To test it, I'm building a simple graph editing tool with it. Here's my problem. When I left click mouse down on the component, then drag something over the edge of the component, I continue to receive MouseMove/MouseUp events. This is the desired behaviour. When I use the Right mouse button, however, the MouseMove/MouseUp events are not fired when I drag off the edge of the component. Does anyone know why the two buttons don't behave the same way, and how I can solve this problem? -David Back to top David Paquette Guest Posted: Thu Oct 21, 2004 7:58 pm    Post subject: Re: Strange Mouse Event Behaviour I Figured it out! .... private procedure WMRButtonDown(var Message: TWMRButtonDown); message WM_RBUTTONDOWN; .... .... procedure TMyComp.WMRButtonDown(var Message: TWMRButtonDown); begin if csCaptureMouse in ControlStyle then MouseCapture := True; inherited; end; .... .... .... It's as simple as that! -David "David Paquette" <nothing (AT) hto (DOT) dsafdas> wrote Quote: Hi All, I'm building a component to be used to build direct manipulation software in.
