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

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

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;
