DoSelectionDropReject Method

In This Topic

Invoke BackgroundSelectionDropReject or ObjectSelectionDropReject event handlers and GoObject.GoObject.OnSelectionDropReject methods to see if any want to prevent a drop.

Syntax

public virtual bool DoSelectionDropReject( 
   GoInputEventArgs evt
)

Parameters

evt

Return Value

true if no drop should occur; false if a drop is acceptable.

Remarks

This is normally called from the GoToolDragging tool's DoMouseMove and DoMouseUp methods, to decide whether a drop is permissible at the given input event point. In Windows Forms, it is also called by DoExternalDrop when dropping GoObjects, for completeness, when the GoToolDragging tool is not used for normal external drag-and-drops. This method must be called before calling DoSelectionDropped, but it may be called many times during a drag before a drop actually happens.
