Capture Button Down Event

[BrotherC]

Hi, I would like to capture the event of a button being pressed down (CButton control class). Windows only sends a command message when the button is released if using OnClickButton().

If you could help out that would be great. Thanks !

Here's one way to do it: subclass CButton and add a new handler for OnLButtonDown. I did it like this and it seems to work:

void CMyButton::OnLButtonDown(UINT nFlags, CPoint point) 
{
	CRect rc;
	GetClientRect(&rc);
	if(rc.PtInRect(point))
	{
		// do stuff here
	}
	
	CButton::OnLButtonDown(nFlags, point);
}

You may also handle WM_NOTIFY messages. Many controls send WM_NOTIFY messagges when something happens with them.
