RE: windows 7 menu-/toolbar drawing bug

This bug was reported before. It is not a WTL problem, it is a bug in REBAR
control in Windows. Because of that, we didn't change anything, hoping it
will be fixed.

 

The problem is not specific to Windows 7, it is also there on Windows XP. It
can be seen when the themes are active.

 

The quick solution that Alain proposed is not a general one because
m_hWndToolBar can be used for REBAR or for a ToolBar. There is no easy way
to check what m_hWndToolBar is. Erasing background for the ToolBar would
cause flicker. If you know that you have a REBAR, that then solution if OK.

 

The full solution would be to derive a class from CWindowImpl using
CReBarCtrl as a base window class, implement OnSize handler and erase
background there.

 

Cheers,

Nenad

Hello,

Ah, so the only fixes in the trunk are SLOW fixes? :)
