- The comment below and all this code is probably due to not using WM_NEXTDLGCTL
- message when changing focus (but just SetFocus() which is not enough), see
- http://blogs.msdn.com/oldnewthing/archive/2004/08/02/205624.aspx for the
- full explanation.
-
- TODO: Do use WM_NEXTDLGCTL and get rid of all this code.
+ 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.
- "Everything you ever wanted to know about the default buttons" or "Why do we
- have to do all this?"
-
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
handled by ::DefWindowProc() (or maybe ::DefDialogProc()) using DM_SETDEFID
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.
