276 "Everything you ever wanted to know about the default buttons" or "Why do we
277 have to do all this?"
278
279 In MSW the default button should be activated when the user presses Enter
280 and the current control doesn't process Enter itself somehow. This is
281 handled by ::DefWindowProc() (or maybe ::DefDialogProc()) using DM_SETDEFID
282 Another aspect of "defaultness" is that the default button has different
283 appearance: this is due to BS_DEFPUSHBUTTON style which is completely
7fb1b2b4
VZ
284 separate from DM_SETDEFID stuff (!). Also note that BS_DEFPUSHBUTTON should
285 be unset if our parent window is not active so it should be unset whenever
286 we lose activation and set back when we regain it.
d78f09e2
VZ
287
288 Final complication is that when a button is active, it should be the default
289 one, i.e. pressing Enter on a button always activates it and not another
290 one.
291
292 We handle this by maintaining a permanent and a temporary default items in
293 wxControlContainer (both may be NULL). When a button becomes the current
294 control (i.e. gets focus) it sets itself as the temporary default which
295 ensures that it has the right appearance and that Enter will be redirected
296 to it. When the button loses focus, it unsets the temporary default and so
297 the default item will be the permanent default -- that is the default button
298 if any had been set or none otherwise, which is just what we want.
299
7fb1b2b4
VZ
300 NB: all this is quite complicated by now and the worst is that normally
301 it shouldn't be necessary at all as for the normal Windows programs
302 DefWindowProc() and IsDialogMessage() take care of all this
77ffb593 303 automatically -- however in wxWidgets programs this doesn't work for
7fb1b2b4
VZ
304 nested hierarchies (i.e. a notebook inside a notebook) for unknown
305 reason and so we have to reproduce all this code ourselves. It would be
306 very nice if we could avoid doing it.
