Re: frame size hints - for Wine

[Mike McCormack <mike codeweavers com>]

Hi All,

I read the thread last November about "frame size hints".

Wine is another "application" where it would be nice to know how large 
the window manager frame is.

Wine needs to know the border sizes when calculating the size of a 
window's client area.  The Win32 API passes the size and location of the 
whole window, including the frame to CreateWindow, so to find the 
correct size of the client area, we should first remove the size of the 
window frame...

The biggest problem is that we need to know this before the window is 
mapped, so that we can send the application a WM_WINDOWPOSCHANGING 
message with its new size :-(

Because we have no reliable way to determine the frame size, Wine 
currently has problems when an application maximizes a window, or 
creates a window the size of the screen... the client area may be 
incorrectly sized, or the borders of the window may not be visible.

If the window manager specification could provide a way to 
(pre-)determine the size of the frame, it would be a good thing for the 
Wine project.
