D&D DragDetect without mouse move distance on Canvas [message #461109] Fri, 16 September 2005 11:27

the D&D Article states that on Windows the mouse has to be
moved a certain distance before the DragDetect Event gets fired.

So far, this is true when dragging from e.g. a Tree.

I have a own implementation of a SWT widget (Canvas) wich contains
child widgets (Item) that can be dragged.
If I press and hold the left mouse button, a DragDetect Event gets
fired after a certain time but without moving the mouse.
That time is rather short, so that the users often accidentally do
a drop which creates a copy of the element.

Why do I get a timed DragDetect instead of the mouse move distance?
Is this a problem/feature in Windows when using a Canvas?

How can I fix this?
