Clamp to Screen: Flickering

[Arokh]

I wrote a Class which clamps Forms to the screen if they are moved near the edge.

After working out some problems, I'm left with just one:

 

Since I'm using the move event, the form is first moved to the mouse position and then to the edge of the screen, resulting in a flickering behavouir.

 

I have 2 ideas to solve the problem, but both need something I don't know how to achive.

 

1)

Prefered solution. (Behavior like Winamp)

The form is moved to the edge without prior move to the mouse.

I would need an event which is fired before the form is moved to the mouse,

and there I would need to be able to cancel the mouse movement (only partially, sometimes both directions).

But I wasn't able to find such an event.

 

2)

Clamp the form when the form is done moving.

The only problem here is that the mouse* events don't work on the frame of the form.

 

 

I have attached the Class.
