Typedef Documentation

APIClassificationVisibilityHandlerProc

typedef bool APIClassificationVisibilityHandlerProc(API_ClassificationVisibilityMode visibilityMode, const GS::Array< API_Guid > &classificationGuids, const API_Guid &classificationItemGuid)

Callback function to handle the visibility of a classification.

Parameters

visibilityMode	[in] specifies what should the callback function return. Has one of the following values: API_ClassificationVisibilityMode Meaning APIClassVis_IsEnabled The callback function should return true if the visibility handling is enabled. APIClassVis_IsClassificationVisible The callback function should return true if the given classification is visible.
classificationGuids	[in] the classification guids of the current element.
classificationItemGuid	[in] the guid of the current classification.

Returns

• true - The result if it was successfull.

APIElemSetSaveOldFormatHandlerProc

typedef GSErrCode APIElemSetSaveOldFormatHandlerProc(API_FTypeID planFileType, GSConstPtr dataPtr, GSPtr *oldDataPtr)

User supplied callback function for handling backward conversion on user data attached to elements.

Parameters

planFileType	[in] File type's ID of the save process
dataPtr	[in] Pointer to the attached user data
oldDataPtr	[out] Pointer to the backward converted user data

Returns

• NoError - The function has completed with success.

Remarks

oldDataPtr is nullptr on call, and should be allocated in the function. If it is nullptr on return, the used data will be deleted from the saved plan.

APIESYMCommandProc

typedef GSErrCode APIESYMCommandProc(const API_ESYMParams *esymParams)

User supplied callback function for handling external symbols.

Parameters

esymParams

[in] This structure contains the various parameters identifying the external symbol (type, index) and the type of operation (new/edit).

Returns

• NoError - The function has completed with success.

Remarks

This is the function which will be called when your add-on installed it with ACAPI_LibraryPart_InstallESYMHandler.

APIIO3DCommandProc

typedef GSErrCode APIIO3DCommandProc(const API_IOParams *ioParams, Modeler::SightPtr sight)

User supplied callback procedure for handling I/O operations.

Parameters

ioParams	[in] This structure contains the various parameters identifying the file to be opened or saved.
sight	[in] The 3D sight pointer.

Returns

• NoError - The function has completed with success.

Remarks

This is the function which will be called when your add-on installed it with ACAPI_AddOnIntegration_InstallFileTypeHandler3D.

APIIOCommandProc

typedef GSErrCode APIIOCommandProc(const API_IOParams *ioParams)

User supplied callback procedure for handling I/O operations.

Parameters

ioParams

[in] This structure contains the various parameters identifying the file to be opened or saved.

Returns

• NoError - The function has completed with success.

Remarks

This is the function which will be called when your add-on installed it with ACAPI_AddOnIntegration_InstallFileTypeHandler. From Archicad 19 you have to enclose the element creation creating in an undoable command scope during a merge file operation. In case you pass empty string parameter to ACAPI_CallUndoableCommand, Archicad replaces it with the default "Paste" undo string. From Archicad 9 merge and open operations can be initiated also with drag drop:

• dropping a file of a registered type onto the frame window (on Windows) results an IO_OPEN method call
• dropping a file of a registered type onto the visible client area of a drawing (floorplan, section, detail) window generates an IO_MERGE operation. In this case the fromDragDrop flag of API_IOParams is set, and the dropOffset field contains the vector that points to the dropping position from the origin. The false value in the noDialog parameter means that the drag drop operation was performed with the right mouse button or with pressing a modifier key (Ctrl on Windows, Alt on the Macintosh).

APIMenuCommandProc

typedef GSErrCode APIMenuCommandProc(const API_MenuParams *menuParams)

User supplied callback procedure for handling menu commands.

Parameters

menuParams

[in] This structure contains the various parameters identifying the menu command.

Returns

• NoError - The function has completed with success.

Remarks

This is the function which will be called when your add-on installed it with ACAPI_MenuItem_InstallMenuHandler. For tool type add-ons, this is the replacement for the original DoCommand function.

APIModulCommandProc

typedef GSErrCode APIModulCommandProc(GSHandle params, GSPtr resultData, bool silentMode)

User supplied callback procedure for handling calls from other add-ons.

Parameters

params	[in/out] This structure contains the parameters of the command passed onto your add-on.
resultData	[out] This structure contains parameters passed back to the caller add-on.
silentMode	[in] This flag tells the add-on to work "silently", i.e. skip all dialogs and warning messages.

Returns

• NoError - The function has completed with success.

Remarks

Your add-on can provide services to other add-ons by calling ACAPI_AddOnAddOnCommunication_RegisterSupportedService in its RegisterInterface function. After that any add-on can call your add-on which knows the command's interface; and this function will be the entry point of your add-on in this case.

APIModulDataMergeHandlerProc

typedef GSErrCode APIModulDataMergeHandlerProc(API_MDSetCmd mode, const GS::UniString &modulName, const API_ModulData *originalInfo, const API_ModulData *toMergeInfo, API_ModulData *destInfo)

User supplied callback procedure for handling module data merge operations.

Parameters

mode	[in] The operation the add-on is called for.
modulName	[in] Identifier name of the modul data (for modules stored in previous versions this parameter is always empty string).
originalInfo	[in] The original module data in the to which data has to be merged into.
toMergeInfo	[in] The incoming module data.
destInfo	[out] The result module data. Your add-on should put the result of the merge in here.

Returns

• NoError - The function has completed with success.

Remarks

This is the function to be called when two conflicting modules need to be merged by your add-on. The handler function pointer must be passed with ACAPI_AddOnIntegration_InstallModulDataMergeHandler. It is also necessary to register this functionality of the add-on with calling ACAPI_AddOnIntegration_RegisterModulDataHandler. The details of the notification process are described in the ModulData Manager section.

APIModulDataSaveOldFormatHandlerProc

typedef GSErrCode APIModulDataSaveOldFormatHandlerProc(API_FTypeID planFileType, GS::HashTable< GS::UniString, API_ModulData * > &modulesToSave)

User supplied callback procedure for converting modules into previous format.

Parameters

planFileType	[in] The old format plan version the project is being saved. In Archicad 13 this can be only APIFType_PlanFile1200.
modulesToSave	[out] A hash table to retrieve the converted module data.

Returns

• NoError - The function has completed with success.

Remarks

In order to save the add-on's moduldata in the proper format into a previous version project file, you need to implement this callback function, and pass it to Archicad with ACAPI_AddOnIntegration_InstallModulDataSaveOldFormatHandler during the Initialize phase. It is also necessary to notify Archicad about this capability of the add-on by calling ACAPI_AddOnIntegration_RegisterModulDataHandler from the RegisterInterface function. This handler function is called whenever the user saves the project into an older format, and tha add-on has any moduldata stored currently into the project. The data should be constructed according to the required version into a dynamically allocated API_ModulData structure, and the pointer of this structure should be pushed into the modulesToSave table. Notice that more modules can be added, should be identified with different names. In Archicad versions prior to 13 were able to store only one moduldata per add-on, this moduldata should be stored with empty string identifier (""). The memory allocated for the converted moduldata by the add-on's handler function will be released by the caller application. For further details of the notification process refer to the ModulData Manager section.

APINavigatorAddOnViewPointDataConvertNewFormatHandlerProc

typedef GSErrCode APINavigatorAddOnViewPointDataConvertNewFormatHandlerProc(API_FTypeID planFileType, const GS::Array< API_NavigatorAddOnViewPointData > &oldFormatVPDataArray, GS::Array< API_NavigatorAddOnViewPointData > &currentFormatVPDataArray)

User supplied callback procedure for converting Navigator AddOn viewpoints into current format.

Parameters

planFileType	[in] The old format plan version being opened.
oldFormatVPDataArray	[in] Navigator AddOn viewpoints in old format.
currentFormatVPDataArray	[out] Navigator AddOn viewpoints in current format. These will be visible after the plan finished opening.

Returns

• NoError - The function has completed with success.

Remarks

In order to convert older version Navigator AddOn viewpoints into current version during plan file opening, you need to implement this callback function, and install it with ACAPI_AddOnIntegration_InstallNavigatorAddOnViewPointDataConvertNewFormatHandler in the Initialize function. It is also necessary to call ACAPI_AddOnIntegration_RegisterNavigatorAddOnViewPointDataHandler from the RegisterInterface function. This handler function is called by Archicad whenever the user opens a plan file, that is in older format. Inside the function the converted viewpoints should be constructed in API_NavigatorAddOnViewPointData structures in the format required by current version of this AddOn, and these structures should be pushed into currentFormatVPDataArray. When Archicad calls this function, it passes an empty currentFormatVPDataArray. If you need to delete a Navigator AddOn viewpoint (e.g. it cannot be converted to current version) then simply do not push it into currentFormatVPDataArray. Note, that if you do not push a root or group, all its descendants will be deleted, even if some descendants were pushed into currentFormatVPDataArray. If you push a viewpoint data with an invalid guid (i.e. one that does not designate an existing root, group or leaf node), it will be skipped, and not created. Order of the items in currentFormatVPDataArray is irrelevant. The hierarchy cannot be changed during conversion. The parentGuid of the pushed structures will be ignored. The item type of the Navigator viewpoints cannot be changed during conversion. The itemType of the pushed structures will be ignored.

APINavigatorAddOnViewPointDataMergeHandlerProc

typedef GSErrCode APINavigatorAddOnViewPointDataMergeHandlerProc(const GS::Array< API_NavigatorAddOnViewPointData > &sourceVPDataArray)

User supplied callback procedure for handling Navigator AddOn viewpoint merge operations.

Parameters

sourceVPDataArray

[in] The list of the Navigator AddOn viewpoints to be merged. These viewpoint roots, groups or leaf nodes come from the merged plan file.

Returns

• NoError - The function has completed with success.

Remarks

This function is called by Archicad when a file merge operation is performed. The handler function should merge the source objects into the project database by calling Navigator AddOn viewpoint related API functions, e.g. ACAPI_Navigator_CreateNavigatorVPItem, ACAPI_Navigator_ChangeNavigatorVPItem.

APINavigatorAddOnViewPointDataSaveOldFormatHandlerProc

typedef GSErrCode APINavigatorAddOnViewPointDataSaveOldFormatHandlerProc(API_FTypeID planFileType, const GS::Array< API_NavigatorAddOnViewPointData > &currentFormatVPDataArray, GS::Array< API_NavigatorAddOnViewPointData > &oldFormatVPDataArray)

User supplied callback procedure for converting Navigator AddOn viewpoints into older format.

Parameters

planFileType	[in] The old format plan version, the project is being saved into.
currentFormatVPDataArray	[in] Navigator AddOn viewpoints in current format.
oldFormatVPDataArray	[out] Navigator AddOn viewpoints in old format. This will be saved into the old format plan.

Returns

• NoError - The function has completed with success.

Remarks

In order to save the Navigator AddOn viewpoints into a previous version project file, you need to implement this callback function, and install it with ACAPI_AddOnIntegration_InstallNavigatorAddOnViewPointDataSaveOldFormatHandler in the Initialize function. It is also necessary to call ACAPI_AddOnIntegration_RegisterNavigatorAddOnViewPointDataHandler from the RegisterInterface function. This handler function is called by Archicad whenever the user saves the project into an older format. Inside the function the converted viewpoints should be constructed in API_NavigatorAddOnViewPointData structures in the format required by the previous version of this AddOn, and these structures should be pushed into oldFormatVPDataArray. When Archicad calls this function, it passes an empty oldFormatVPDataArray. If you need to delete a Navigator AddOn viewpoint (e.g. it cannot be converted to previous version) then simply do not push it into oldFormatVPDataArray. Note, that if you do not push a root or group, all its descendants will be deleted, even if some descendants were pushed into oldFormatVPDataArray. If you push a viewpoint data with an invalid guid (i.e. one that does not designate an existing root, group or leaf node), it will be skipped, and not created. Order of the items in oldFormatVPDataArray is irrelevant. The hierarchy cannot be changed during conversion. The parentGuid of the pushed structures will be ignored. The item type of the Navigator viewpoints cannot be changed during conversion. The itemType of the pushed structures will be ignored.

APIPaletteControlCallBackProc

typedef GSErrCode APIPaletteControlCallBackProc(Int32 referenceID, API_PaletteMessageID messageID, GS::IntPtr param)

User supplied callback function for handling special messages for modeless palettes.

Parameters

referenceID	[in] The unique ID that identifies the modeless palette.
messageID	[in] Event to be handled in the palette control callback procedure.
param	[out] Return parameter, used for APIPalMsg_IsPaletteVisible.

Returns

• NoError - The function has completed with success.

Remarks

You can register this function with ACAPI_RegisterModelessWindow. From now on, it will be your responsibility to adjust the behavior of your palette to the other palettes. The following types of events will come for your custom window:

Message type	Description
APIPalMsg_ClosePalette	The API asks the add-on to close its palette.
APIPalMsg_HidePalette_Begin	Your palette should be hidden for some reason, e.g. the user chose Hide All Palettes from the menu.
APIPalMsg_HidePalette_End	The palette can be shown again if needed.
APIPalMsg_DisableItems_Begin	Certain palette items should be disabled, because the user is performing an input. This is necessary because you shouldn't make any modifications to the database during input.
APIPalMsg_DisableItems_End	The reason behind APIPalMsg_DisableItems_Begin is gone; you can enable the items on the palette.
APIPalMsg_OpenPalette	Sent when the palette should be opened automatically as set in the Work Environment. Your palette should pass a GUID when created: DG::Palette (resourceId, paletteGuid) to make this work.
APIPalMsg_IsPaletteVisible	The Work Environment queries the palette for its visibility status on closing the current document/quitting the application. If you return true in param (really a bool*), then Archicad will send a APIPalMsg_OpenPalette to your add-on on next launch, so that you can re-open your add-on's palette.

The supplied refCon parameter should be the same in the ACAPI_AddOnIntegration_InstallFileTypeHandler function, which you have to call from your Initialize routine. The methodFlags parameter defines which dialogs' file type popup should contain the registered file type:

Flag	File Dialog
Open2DSupported	Open as 2D
Merge2DSupported	Merge
OpenLibPartSupported	Open Library Item
SaveAs2DSupported	Save as 2D
SaveAs3DSupported	Save as 3D
SaveAsFlySupported	Create Fly-Through/Sun Study
Import2DDrawingSupported	Import as Drawing

From API v4.2 you have the possibility to register the MIME type for the file as well. MIME (Multipurpose Internet Mail Extension) types are commonly accepted identifiers for certain media types. Specifying the MIME type makes the file format identification more accurate in the File Type Manager. If you decide to use this feature, you can do this in the following way:

• in the GRC file the string resource that describes the file format must contain two items: the descriptive name of the file format (e.g. "DWF File") the assigned MIME type (e.g. "model/vnd.dwf")
• the descriptive name of the file format (e.g. "DWF File")
• the assigned MIME type (e.g. "model/vnd.dwf")
• in the descStrResItemID parameter of the ACAPI_AddOnIntegration_RegisterFileType function you must pass 0

  Example

  In the localizable GRC file:

ACAPI_AddOnIntegration_RegisterInfoBoxPanel()

GSErrCode ACAPI_AddOnIntegration_RegisterInfoBoxPanel	(	Int32	refCon,

This function checks for the availability of an other add-on's command, without which it cannot run. The other add-on should provide all the necessary information. The function should be called from the RegisterInterface function of the add-on.

Example

//------------------------------------------------------
// Interface definitions
//------------------------------------------------------
GSErrCode RegisterInterface (void)
 
{
    GSErrCode   err;
 
    //
    // Register command services

ACAPI_AddOnIntegration_RegisterSettingsObserver()

GSErrCode ACAPI_AddOnIntegration_RegisterSettingsObserver

(

const API_ElemType &

tool

)

Create an observer to an element settings dialog.

Since

Archicad 26

Parameters

tool	[in] The element type that identifies the settings dialog

Returns

• APIERR_BADPARS - The passed element type is invalid.
• APIERR_BADID - The passed tool does not identify a valid toolbox item (including invisible tools).
• NoError - The function has completed with success.

Remarks

This function creates an observer for an element settings dialog specified by tool. In order to get settings dialog create or destroy events you must install the settings handler callback functions with ACAPI_AddOnIntegration_InstallSettingsHandler. This function should be called from your add-on's RegisterInterface routine. You can register more than one observers from the same add-on for different settings dialogs. From version 26 the tool and variation parameters were merged into a single API_ElemType parameter.

Example

Refer to the Panel_Test
 
example project of the API Development Kit.

ACAPI_AddOnIntegration_RegisterSettingsPanel()

GSErrCode ACAPI_AddOnIntegration_RegisterSettingsPanel	(	Int32	refCon,
		const API_ElemType &	tool,
		short	iconId,
		short	stringId,
		short	pageId,
		short	growType = 0,
		bool	visibleByDefault = false
	)

Appends a custom panel to an element settings dialog.

Since

Archicad 26

Parameters

refCon	[in] Unique reference number chosen for this panel
tool	[in] The element type that identifies the settings dialog
iconId	[in] Panel icon resource ID
stringId	[in] Title text to appear in the handler area of the panel
pageId	[in] Dialog resource ID of the tabpage
growType	[in] Grow type of the tab page: can be DG_DLG_NOGROW, DG_DLG_HGROW, DG_DLG_VGROW, or DG_DLG_HGROW | DG_DLG_VGROW. This parameter is optional, the default is DG_DLG_NOGROW.
visibleByDefault	[in] Show or hide the panel by default (optional parameter, false if omitted)

Returns

• APIERR_BADPARS - The passed element type is invalid.
• APIERR_BADID - The passed tool / variation parameter pair does not identify a valid toolbox item (including invisible tools).
• NoError - The function has completed with success.

Remarks

This function appends a new panel into an element settings dialog specified by tool and variation. In order to get panel create/destroy events you must install the panel handler callback functions with ACAPI_AddOnIntegration_InstallPanelHandler. For more details refer to the general description of Custom Panels in Settings Dialogs. From version 26 the tool and variation parameters were merged into a single API_ElemType parameter.

Example

Resources in the GRC file:

ACAPI_KeepInMemory()

void ACAPI_KeepInMemory

(

bool

keepIn

)

Instructs the host application to keep the add-on in the memory after execution.

Parameters

keepIn

[in] If true the add-on will stay in the memory.

Remarks

This function is used to keep the add-on in the memory. You should call this function with true each time your add-on is called to stay in memory. The values of all your global variables stay the same between the calls to your add-on. Also, when in memory, the Initialize and the FreeData functions of your add-on are not called. See more about this topic at the Control the Load/Unload Mechanism part of the Tips and Tricks.

ACAPI_LibraryPart_InstallESYMHandler()

GSErrCode ACAPI_LibraryPart_InstallESYMHandler	(	GSType	signature,
		APIESYMCommandProc *	handlerProc
	)

Installs a callback for handling external symbols.

Parameters

signature	[in] A four-character identifier of the external symbol.
handlerProc	[in] The callback function to handle the creation and the editing of the external symbol.

Returns

• NoError - The function has completed with success.

Remarks

This function should be called in the Initialize function of your add-on.

Example

// -----------------------------------------------------------------------------
// Called when the add-on has been loaded into memory
// -----------------------------------------------------------------------------
GSErrCode Initialize (void)
 
{
    GSErrCode    err = NoError;
 
    err = ACAPI_LibraryPart_InstallESYMHandler ('ABCD', APIESYMCommandProc);
 
    return err;
}   // Initialize

ACAPI_LibraryPart_RegisterESYM()

GSErrCode ACAPI_LibraryPart_RegisterESYM	(	GSType	signature,
		API_LibTypeID	typeID,
		short	stringResID
	)

Registers an external symbol type with Archicad.

Parameters

signature	[in] Unique identifier of the new symbol type (a four-character ID).
typeID	[in] Type of the new symbol (can be API_ObjectID, API_LampID, API_WindowID, or API_DoorID).
stringResID	[in] Resource containing the description of the new symbol type.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - Invalid symbol type.

Remarks

This function should be called from your add-on's RegisterInterface routine. More than one external symbol can be registered from one add-on. After registration you should also install a callback function with ACAPI_LibraryPart_InstallESYMHandler in your Initialize function, which will handle the events coming from Archicad.

Example

//------------------------------------------------------
// Interface definitions
//------------------------------------------------------
GSErrCode RegisterInterface (void)
{
    GSErrCode   err;
 
    // Register ESYM
    err = ACAPI_LibraryPart_RegisterESYM ('GRPH', API_LampID, 32611);
 
    return err;
}               /* RegisterInterface */

ACAPI_LibraryPart_RegisterSubtype()

GSErrCode ACAPI_LibraryPart_RegisterSubtype	(	GSType	signature,
		short	templateFileResID,
		bool	transparentNode,
		short	stringResID,
		short	smallIconResID,
		short	largeIconResID,
		API_TBoxGroup	toolGroupId,
		API_TBoxEnabled	enableFlags,
		short	defaultsResID
	)

Registers a new library part subtype.

Parameters

signature	[in] A four-character identifier of this library part subtype
templateFileResID	[in] 'FILE' resource ID of the subtype template library part compiled into the add-on
transparentNode	[in] Objects of this subtype can be shown on higher ancestry levels as well
stringResID	[in] Resource ID of the library part subtype description string
smallIconResID	[in] Resource ID of the small-sized toolbox (toolbar) item icon
largeIconResID	[in] Resource ID of the large-sized toolbox item icon
toolGroupId	[in] Toolbox item position
enableFlags	[in] Enable or disable the subtype tool depending on the active window
defaultsResID	[in] ID of the 'ACP0' resource that contains the element default values for this subtype

Returns

• APIERR_BADPARS - templateFileResID refers to an invalid 'FILE' resource or the built-in library part cannot be accepted as subtype template.
• NoError - The function has completed with success.

Remarks

This function registers a new library part subtype. In order to have an own element subtype the add-on must contain a built-in library part in its reource module. This library part will be loaded into the active libraries, and become a new node in the ancestry tree. The new element type will be identified with the signature identifier chosen by the add-on's writer. The signature should be unique in order to avoid collisions. You may pass 0 in the signature parameter if you do not need a new element type but a single subtype node. The subtype can appear in the toolbox as an external tool, and also on the Windows toolbar. In this case you must pass two valid icon resource IDs in the smallIconResID and the largeIconResID parameters. The size of the icons should be 16x16 and 30x21 pixels respectively. You can specify the position of the subtype item inserted into the toolbox with the toolGroupId parameter as follows:

API_TBoxGroup	Meaning
TBoxGroup_Root	The subtype tool item will be appended to the group of model element tools
TBoxGroup_Objects	The subtype tool item will be added to the object tools
TBoxGroup_Openings	The subtype tool item will be added to the window/door tools

You can control the availability of the subtype tool in the toolbox by setting the enableFlags bits:

API_TBoxEnabled	The subtype tool is enabled
API_TBoxEnabled_FloorPlan	on floor plan window
API_TBoxEnabled_ModelSection	on model type section and elevation windows
API_TBoxEnabled_DrawingSection	on drawing type section and elevation windows
API_TBoxEnabled_3D	on 3D model window
API_TBoxEnabled_Detail	on detail window
API_TBoxEnabled_Layout	on layout and master layout windows
API_TBoxEnabled_Worksheet	on worksheet window
API_TBoxEnabled_ModelInteriorElevation	on model type interior elevation windows
API_TBoxEnabled_DrawingInteriorElevation	on drawing type interior elevation windows

If you want to register your subtype tool without appearing in the toolbox, pass 0 for both the smallIconResID and the largeIconResID parameters. If you register a subtype tool you should define the factory default values for this element type in an 'ACP0' resource. The element default will be initialized with these parameters when no preferences data is stored. The structure of this resource is shown at the example below. The resource ID should be passed in the defaultsResID parameter. Learn more about this topic at the general description of Library Part Subtypes.

Example

Resources in the .GRC file:

ACAPI_MenuItem_InstallMenuHandler()

GSErrCode ACAPI_MenuItem_InstallMenuHandler	(	short	menuStrResID,
		APIMenuCommandProc *	handlerProc
	)

Installs a callback procedure for handling the add-on's menu commands.

Parameters

menuStrResID	[in] An identifier of the menu to install the callback procedure for. This should be the same what you used in the ACAPI_MenuItem_RegisterMenu as a menu string resource number in the RegisterInterface function.
handlerProc	[in] The callback function to handle the menu commands.

Returns

• NoError - The function has completed with success.

Remarks

This function should be called in the Initialize function of your add-on. It installs the callback function which is called when the user chooses one of your menu commands.

Example

// -----------------------------------------------------------------------------
// Called when the add-on has been loaded into memory
// -----------------------------------------------------------------------------
GSErrCode Initialize (void)
 
{
    GSErrCode    err = NoError;
 
    err = ACAPI_MenuItem_InstallMenuHandler (32500, APIMenuCommandProc);
 
    return err;
}   // Initialize

ACAPI_MenuItem_RegisterMenu()

GSErrCode ACAPI_MenuItem_RegisterMenu	(	short	menuStrResID,
		short	promptStrResID,
		APIMenuCodeID	menuPosCode,
		GSFlags	menuFlags
	)

Registers the menu items of the add-on.

Parameters

menuStrResID	[in] The resource ID of the menu resource, which should be in the resource fork of the add-on.
promptStrResID	[in] The resource ID of the propmt string resource, which should be in the resource fork of the add-on. These strings appear in the status bar.
menuPosCode	[in] Defines the server application's menu to insert the command into.
menuFlags	[in] Flags describing whether you would like to see any separator item in the menu before or after the registered menu item. Its possible values are: MenuFlag_Default, MenuFlag_SeparatorBefore, and MenuFlag_SeparatorAfter

Returns

• NoError - The function has completed with success.

Remarks

This function should be called from the RegisterInterface routine in your add-on. You can register more than one menu from the same add-on, even appearing in different menus of the server application. The supplied menuStrResID parameter should be the same in the ACAPI_MenuItem_InstallMenuHandler function, which you have to call from your Initialize routine. The following scenarios are possible:

• the add-on inserts one menu item at the position defined by menuPosCode 'STR#' 32500 "Menu Description" { / [ 1] / "My add-on's solo menuitem" }
• the add-on inserts a submenu at the position defined by menuPosCode 'STR#' 32501 "Menu Description" { / [ 1] / "My add-on's submenu" / [ 2] / "My add-on's menuitem #1" / [ 3] / "My add-on's menuitem #2" }
• the add-on inserts its own main menu; menuPosCode should be MenuCode_UserDef 'STR#' 32502 "Menu Description" { / [ 1] / "My add-on's main menu" / [ 2] / "My add-on's solo menuitem" }
• the add-on inserts its own main menu with a submenu; menuPosCode should be MenuCode_UserDef 'STR#' 32503 "Menu Description" { / [ 1] / "My add-on's main menu" / [ 2] / "My add-on's submenu" / [ 3] / "My add-on's menuitem #1" / [ 4] / "My add-on's menuitem #2" } As you see, the add-on may define its own main menu, if it uses MenuCode_UserDef and the menu position. In this case the first item in the STR# resource will be the title of the main menu, and the other items correspond to the menu items in the non-main menu case. If this first item is the same as one of the server application's main menu titles, then the API won't open a new main menu, rather it inserts the add-on's menu into the original main menu, as defined by the rules for that menu. This also means if you use an already existing menu title (e.g. Window) which doesn't have an insertion place for add-ons, your add-on's menu won't appear. This implies that the location of the add-on within the Add-Ons folder doesn't have any impact on the menu position of your add-on's commands. The appearance of menu items can be controlled by control codes appended to the menu item string resource as described in the Required Resources section.

Example

In the GRC file:

ACAPI_Property_InstallPropertyObjectHandler()

GSErrCode ACAPI_Property_InstallPropertyObjectHandler	(	short	strResID,
		APIPropertyObjectCommandProc *	propertyCommandProc
	)

Installs the property handler function for the given menu item.

Parameters

strResID	[in] The string resource ID you install the property handler for.
propertyCommandProc	[in] The property command handler function.

Returns

• NoError - The function has completed with success.

Remarks

The string resource will appear in Archicad's dialogs. This function should be called from the Initialize function of the add-on, after registering the property handler with ACAPI_Property_RegisterPropertyObjectHandler.

Example

//------------------------------------------------------
// Called after the add-on has been loaded into memory
//------------------------------------------------------
GSErrCode Initialize (void)
{
    ACAPI_MenuItem_InstallMenuHandler (MenuResId, Callback_Check_AVA_OR_DIN_MenuItem);
    ACAPI_Property_InstallPropertyObjectHandler (PropertyResId, Callback_Property);
 
    return NoError;
}

ACAPI_Property_InstallPropertyVisibilityHandler()

GSErrCode ACAPI_Property_InstallPropertyVisibilityHandler

(

APIPropertyVisibilityHandlerProc *

handlerProc

)

Installs the property visibility handler function.

Parameters

handlerProc

[in] The property visibility handler function.

Returns

• NoError - The function has completed with success.

Remarks

This function should be called from the Initialize function of the add-on, after registering the property handler with ACAPI_Property_RegisterPropertyVisibilityHandler.

Example

//------------------------------------------------------
// Called after the add-on has been loaded into memory
//------------------------------------------------------
GSErrCode APIMenuCommandProc_Main   (const API_MenuParams *menuParams);
bool PropertyVisibilityHandler (API_PropertyVisibilityMode visibilityMode, const GS::Array<API_Guid>& classificationGuids, const API_Guid& propertyDefinitionGuid);
 
GSErrCode Initialize (void)
{
    GSErrCode err = ACAPI_MenuItem_InstallMenuHandler (32500, APIMenuCommandProc_Main);
    if (err != NoError) {
        return err;
    }
 
    err = ACAPI_Property_InstallPropertyVisibilityHandler (PropertyVisibilityHandler);
    if (err != NoError) {
        return err;
    }
 
    ACAPI_KeepInMemory (true);
    return NoError;
}

(

short

assignStrResID

)

Registers a property handler.

Parameters

assignStrResID

[in] The string resource ID, which will be used in Archicad's dialogs.

Returns

• NoError - The function has completed with success.

Remarks

This function should be called from the RegisterInterface routine in your add-on.

Example

//------------------------------------------------------
// Interface definitions
//------------------------------------------------------
GSErrCode RegisterInterface (void)
{
    ACAPI_MenuItem_RegisterMenu (MenuResId, MenuTextResId, MenuCode_Calculate, MenuFlag_Default);
    ACAPI_Property_RegisterPropertyObjectHandler (PropertyResId);

ACAPI_Property_RegisterPropertyVisibilityHandler()

GSErrCode ACAPI_Property_RegisterPropertyVisibilityHandler

(

void

)

Tells Archicad that your add-on wants to modify property visibility.

Returns

• NoError - The function has completed with success.

Remarks

This function should be called from the RegisterInterface routine in your add-on.

Example

//------------------------------------------------------
// Interface definitions
//------------------------------------------------------
GSErrCode RegisterInterface (void)
{
    GSErrCode err = ACAPI_MenuItem_RegisterMenu (32500, 32600, MenuCode_UserDef, MenuFlag_Default);
    if (err != NoError) {
        return err;
    }
 
    err = ACAPI_Property_RegisterPropertyVisibilityHandler ();
    if (err != NoError) {
        return err;
    }
 
    return NoError;
}   // RegisterInterface

ACAPI_RegisterModelessWindow()

GSErrCode ACAPI_RegisterModelessWindow	(	Int32	referenceID,
		APIPaletteControlCallBackProc *	callBackProc,
		GSFlags	controlFlags,
		const API_Guid &	paletteGuid = APINULLGuid
	)

Registers a modeless palette in the API.

Parameters

referenceID	[in] Arbitrary number to uniquely identify your modeless palette. (You can use the resource ID if you wish.)
callBackProc	[in] Callback procedure for handling special API messages. It is called by the API, independently of DG.
controlFlags	[in] Define the behavior of the palette above different Archicad windows (plan, 3D, section, layout), and in case of selection.
paletteGuid	[in] A unique identifier for recording the state of the palette in the Work Environment. Optional parameter, can be omitted.

Returns

• NoError - The function has completed with success.
• APIERR_BADID - The passed referenceID has already been used.
• APIERR_MEMFULL - No free memory was available for the new entry.

Remarks

Modeless palettes now can be opened with the normal DG functions (either DGModelessInit, or DG::Palette). However, the API should know about the existence of an add-on's palette, so that it could send special messages to the palette (see APIPaletteControlCallBackProc). This function registers the add-on's modeless window with the API; call it from the Initialize function. API 11 introduced new values for the controlFlags parameter: API_PalEnabled_Worksheet, API_PalEnabled_Elevation, and API_PalEnabled_InteriorElevation.

Example

GSErrCode Initialize    (void)
{
    GSErrCode err = ACAPI_MenuItem_InstallMenuHandler (DGTEST_MENU_STRINGSID, MenuCommandHandler);
 
    // If the palette is constructed and registered, the add-on will be not unloaded from the memory while Archicad runs.
    ACAPI_RegisterModelessWindow (OwnerDrawnListBoxPalette::ODLBPaletteRefId (),
                                  OwnerDrawnListBoxPalette::PaletteAPIControlCallBack,
                                  API_PalEnabled_FloorPlan + API_PalEnabled_Section + API_PalEnabled_Elevation +
                                  API_PalEnabled_InteriorElevation + API_PalEnabled_3D +
                                  API_PalEnabled_Detail + API_PalEnabled_Worksheet + API_PalEnabled_Layout +
                                  API_PalEnabled_DocumentFrom3D + API_PalEnabled_ModelCompare, GSGuid2APIGuid (OwnerDrawnListBoxPalette::ODLBPaletteGuid ()));
 
    if (err != NoError)
        DBPrintf ("DG_Test:: Initialize() ACAPI_MenuItem_InstallMenuHandler failed\n");
 
    return err;
}       // Initialize
