[perl-win32-gui-hackers] -background option and windows

[Robert May]

I've been looking at a few of the bug reports regarding background 
colours of windows/controls.

(1) It appears that the '-background' option was never intended to work 
with  windows (Win32::GUI::Window, Win32::GUI::Dialog) and that the only 
way to change the background colour of a window is using the -class 
option with a coloured brush.   It might be possible to extend the 
WM_PAINT and/or WM_ERASEBKGND handlers to cope with this - is it work 
exploring?

[-background, should work with most controls (but not Buttons - see 
MSDN).  However, class brushes are ignored for such controls - I have a 
fix for this.]

(2) Does anyone know or have any opinions on what the behaviour for a 
RichEdit control in readonly mode with a given background colour should 
be.   Current behaviour is that if no -background option is given then 
the background is 'white' (COLOR_WINDOW) when read/write and 'grey' 
(COLOR_BTNFACE) when readonly.  If a -background option is given, then 
this colour is used regardless.  My view is that this is a reasonable 
approach, but I thought I'd ask.
