  • Article

Call this function to create a dragging bitmap for the given item in a tree view control, create an image list for the bitmap, and add the bitmap to the image list.

CImageList* CreateDragImage( 
   HTREEITEM hItem  
);

Parameters

  • hItem
    Handle of the tree item to be dragged.

Return Value

Pointer to the image list to which the dragging bitmap was added, if successful; otherwise NULL.

Remarks

An application uses the image-list functions to display the image when the item is being dragged.

The CImageList object is permanent, and you must delete it when finished. For example:

HTREEITEM hItem =m_TreeCtrl.GetSelectedItem();

CImageList* pImageList = m_TreeCtrl.CreateDragImage(hItem);

// Do something with the image list. 

delete pImageList;
