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