Hi all
I have only been playing with Win32::Gui for about 11 hours so far, but
its doing almost everything I want it to do so far (windows, buttons,
-onEVENT, hooking it into Win32:GuiTest, all works great...)
Cool!
... but, like most newbies, there are always some things that elude me:
Question #1: Can Button objects have a foreground and background color?
It doesnt seem to work for me (no idea why)
Sadly not. The foreground/background colours of most controls are
handled internally by processing the
WM_CTLCOLOREDIT/WM_CTLCOLORSTATIC/WM_CTLCOLORBTN/WM_CTLCOLORLISTBOX
messages. Although the WM_CTLCOLORBTN message looks promising, the
microsoft documentation says:
"The WM_CTLCOLORBTN message is sent to the parent window of a button
before drawing the button. The parent window can change the button's
text and background colors. However, only owner-drawn buttons respond to
the parent window processing this message."
See

Question #2: Can the font and color in Button objects be chosen?
I'm not sure about font. Have you tried creating a new font object, and
passing it to the button constructor with a-font option? If not, then
the answer is still yes, but not easily - you'll need to process the
NM_CUSTOMDRAW messages for the button. The MSDN details are at:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/buttons/buttonreference/buttonmessages/wm_ctlcolorbtn.asp
and you'll find an example of how do do (simple) custom draw for a list
view at
http://perl-win32-gui.sourceforge.net/cgi-bin/wiki.cgi?Change_Listview_Item_Color
See how you get on, and show us where you got to if you need more help.
I have not personally looked at customdraw with buttons, but it may be
that you have to do all the drawing yourself.
Regards,
Rob.
