I'm writing an app (in C++) which uses WM_LBUTTONDBLCLK.

It's all working fine except but I don't always get the DBLCLK message. Quite often I get two WM_LBUTTONDOWN messages instead.

I've looked at the mouse position - it doesn't move.

I've looked at the time between 开发者_如何学Cthe two WM_LBUTTONDOWN messages - it's well within the value returned by GetDoubleClickTime()

I'm returning 0 for WM_LBUTTONDOWN, WM_LBUTTONUP and WM_LBUTTONDBLCLK.

What would cause this? I'm stumped.

PS: I've tried Windows XP and 7 - same result.

To provoking WM_RBUTTONDBLCLK and WM_LBUTTONDBLCLK cases instead of 2 pairs of buttondown and ups you have to add CS_DBLCLKS flag in your windows style.
