/*
- "Everything you ever wanted to know about the default buttons" or "Why do we
- have to do all this?"
+ In normal Windows programs there is no need to handle default button
+ manually because this is taken care by the system provided you use
+ WM_NEXTDLGCTL and not just SetFocus() to switch focus betweeh the controls
+ (see http://blogs.msdn.com/oldnewthing/archive/2004/08/02/205624.aspx for
+ the full explanation why just calling SetFocus() is not enough).
+
+ However this only works if the window is a dialog, i.e. uses DefDlgProc(),
+ but not with plain windows using DefWindowProc() and we do want to have
+ default buttons inside frames as well, so we're forced to reimplement all
+ this logic ourselves. It would be great to avoid having to do this but using
+ DefDlgProc() for all the windows would almost certainly result in more
+ problems, we'd need to carefully filter messages and pass some of them to
+ DefWindowProc() and some of them to DefDlgProc() which looks dangerous (what
+ if the handling of some message changes in some Windows version?), so doing
+ this ourselves is probably a lesser evil.
+
+ Read the rest to learn everything you ever wanted to know about the default
+ buttons but were afraid to ask.
+
In MSW the default button should be activated when the user presses Enter
and the current control doesn't process Enter itself somehow. This is
to it. When the button loses focus, it unsets the temporary default and so
the default item will be the permanent default -- that is the default button
if any had been set or none otherwise, which is just what we want.
-
- NB: all this is quite complicated by now and the worst is that normally
- it shouldn't be necessary at all as for the normal Windows programs
- DefWindowProc() and IsDialogMessage() take care of all this
- automatically -- however in wxWidgets programs this doesn't work for
- nested hierarchies (i.e. a notebook inside a notebook) for unknown
- reason and so we have to reproduce all this code ourselves. It would be
- very nice if we could avoid doing it.
