virtual L_INT LAnnAutomation::GetAutoCursor(uItem, phCursor)

L_UINT uItem;	/* value that specifies the cursor */
HCURSOR *phCursor;	/* address of an HCURSOR variable */

Gets one of the cursors associated with automated annotations.

Parameter	Description
uItem	Value that specifies the cursor to be displayed on various actions. Possible values are:
	Value	Meaning
	ANNAUTOCURSOR_DEFAULT	[0] Displayed when cursor is over the annotation container, and other action is occurring. The default is the windows predefined cursor IDC_ARROW.
	ANNAUTOCURSOR_DRAWNEW	[1] Displayed when drawing a new annotation (design mode). This is displayed on all tools except for ANNTOOL_SELECT (which displays the ANNAUTOCURSOR_DEFAULT).
	ANNAUTOCURSOR_HANDLE	[2] Displayed in design mode, when cursor is over an annotation handle.
	ANNAUTOCURSOR_HOTSPOT	[3] Displayed in run mode, when cursor over one of the following objects:
		ANNOBJECT_BUTTON
		ANNOBJECT_HOTSPOT
		ANNOBJECT_FREEHANDHOTSPOT
		ANNOBJECT_AUDIO
		ANNOBJECT_VIDEO
		ANNOBJECT_PUSHPIN
	ANNAUTOCURSOR_MOVE	[4] Displayed in design mode, when an annotation is selected and the cursor is over the selected annotation (but not over the annotation handle).
	ANNAUTOCURSOR_SELECT	[5] Displayed in design mode, when hovering over an unselected annotation. The default is the windows predefined cursor IDC_IBEAM.
	ANNAUTOCURSOR_TEXT	[6] Displayed in design mode, when entering text into one of the following text annotations:
		ANNOBJECT_TEXT
		ANNOBJECT_TEXTPOINTER
		ANNOBJECT_RTF
		ANNOBJECT_NOTE
	The default is the windows predefined cursor IDC_IBEAM.
	ANNAUTOCURSOR_WAIT	[7] Displayed during any wait operation. The default is the windows predefined cursor IDC_WAIT.
phCursor	Address of an HCURSOR variable to be updated with the requested annotation cursor.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Call this function to retrieve a copy of one of the annotation cursors. It is the callers responsibility to call DestroyCursor() on the retrieved cursor when finished using the cursor. To customize the annotation cursors, call LAnnAutomation::SetAutoCursor.

Example

// This sample swaps the Default and Move annotation cursors

L_INT LAnnAutomation_GetAutoCursorExample(LAnnAutomation *plAutomation) 
{
   L_INT nRet;
   HCURSOR hCursorMove, hCursorDefault; 
   // Get copy of original cursors
   nRet = plAutomation->GetAutoCursor(ANNAUTOCURSOR_DEFAULT, &hCursorDefault); 
   if(nRet != SUCCESS)
      return nRet;
   nRet = plAutomation->GetAutoCursor(ANNAUTOCURSOR_MOVE, &hCursorMove); 
   if(nRet != SUCCESS)
      return nRet;
   // Change
   nRet = plAutomation->SetAutoCursor(ANNAUTOCURSOR_DEFAULT, hCursorMove); 
   if(nRet != SUCCESS)
      return nRet;
   nRet = plAutomation->SetAutoCursor(ANNAUTOCURSOR_MOVE, hCursorDefault); 
   if(nRet != SUCCESS)
      return nRet;
   // Cleanup
   DestroyCursor(hCursorMove); 
   DestroyCursor(hCursorDefault); 
   return SUCCESS;
