TVTDragImage.RecaptureBackground Method

Virtual Tree View

Notification by the drop target tree to update the background image because something in the tree has changed.

Pascal
procedure RecaptureBackground(Tree: TBaseVirtualTree; R: TRect; VisibleRegion: HRGN; CaptureNCArea: Boolean; ReshowDragImage: Boolean);
Notes

The passed rectangle is given in client coordinates of the current drop target tree (given in Tree). The caller does not 

check if the given rectangle is actually within the drag image. Hence this method must do all the checks. This method 

does nothing if the system manages the drag image.
