279 "Everything you ever wanted to know about the default buttons" or "Why do we
280 have to do all this?"
281
282 In MSW the default button should be activated when the user presses Enter
283 and the current control doesn't process Enter itself somehow. This is
284 handled by ::DefWindowProc() (or maybe ::DefDialogProc()) using DM_SETDEFID
285 Another aspect of "defaultness" is that the default button has different
286 appearance: this is due to BS_DEFPUSHBUTTON style which is completely
7fb1b2b4
VZ
287 separate from DM_SETDEFID stuff (!). Also note that BS_DEFPUSHBUTTON should
288 be unset if our parent window is not active so it should be unset whenever
289 we lose activation and set back when we regain it.
d78f09e2
VZ
290
291 Final complication is that when a button is active, it should be the default
292 one, i.e. pressing Enter on a button always activates it and not another
293 one.
294
295 We handle this by maintaining a permanent and a temporary default items in
296 wxControlContainer (both may be NULL). When a button becomes the current
297 control (i.e. gets focus) it sets itself as the temporary default which
298 ensures that it has the right appearance and that Enter will be redirected
299 to it. When the button loses focus, it unsets the temporary default and so
300 the default item will be the permanent default -- that is the default button
301 if any had been set or none otherwise, which is just what we want.
302
7fb1b2b4
VZ
303 NB: all this is quite complicated by now and the worst is that normally
304 it shouldn't be necessary at all as for the normal Windows programs
305 DefWindowProc() and IsDialogMessage() take care of all this
77ffb593 306 automatically -- however in wxWidgets programs this doesn't work for
7fb1b2b4
VZ
307 nested hierarchies (i.e. a notebook inside a notebook) for unknown
308 reason and so we have to reproduce all this code ourselves. It would be
309 very nice if we could avoid doing it.
