handled by ::DefWindowProc() (or maybe ::DefDialogProc()) using DM_SETDEFID
Another aspect of "defaultness" is that the default button has different
appearance: this is due to BS_DEFPUSHBUTTON style which is completely
- separate from DM_SETDEFID stuff (!).
+ separate from DM_SETDEFID stuff (!). Also note that BS_DEFPUSHBUTTON should
+ be unset if our parent window is not active so it should be unset whenever
+ we lose activation and set back when we regain it.
Final complication is that when a button is active, it should be the default
one, i.e. pressing Enter on a button always activates it and not another
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.
- Remark that we probably don't need to send DM_SETDEFID as we don't use
- ::IsDialogMessage() (which relies on it) any longer but OTOH it probably
- doesn't hurt neither.
+ 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.
