3 wxWindow is the base class for all windows. Any children of the window will be deleted
4 automatically by the destructor before the window itself is deleted.
6 %Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
7 %help text. These must not be called by a user program and are documented only for illustration.
8 %On several platforms, only a few of these handlers are actually written (they are not always
9 %needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
10 %the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
11 %platform can implement its native behaviour or just ignore the event if nothing needs to be

260 \func{bool

262 This function simply generates a
\helpref{wxCloseEvent

} whose
263 handler usually tries to close the window. It doesn't close the window itself,
266 \wxheading{Parameters
}
268 \docparam{force
}{{\tt false
} if the window's close handler should be able to veto the destruction
269 of this window,
{\tt true
} if it cannot.
}
273 Close calls the
\helpref{close handler
}{wxcloseevent
} for the window, providing
274 an opportunity for the window to choose whether to destroy the window.
275 Usually it is only used with the top level windows (wxFrame and wxDialog
276 classes) as the others are not supposed to have any special OnClose() logic.
278 The close handler should check whether the window is being deleted forcibly,
279 using
\helpref{wxCloseEvent::GetForce
}{wxcloseeventgetforce
}, in which case it
280 should destroy the window using
\helpref{wxWindow::Destroy
}{wxwindowdestroy
}.
282 {\it Note
} that calling Close does not guarantee that the window will be
283 destroyed; but it provides a way to simulate a manual close of a window, which
284 may or may not be implemented by destroying the window. The default
285 implementation of wxDialog::OnCloseWindow does not necessarily delete the
286 dialog, since it will simply simulate an wxID
\_CANCEL event which is handled by
287 the appropriate button event handler and may do anything at all.
289 To guarantee that the window will be destroyed, call
290 \helpref{wxWindow::Destroy

302 \func{wxSize
}{ConvertDialogToPixels

304 Converts a point or size from dialog units to pixels.
306 For the x dimension, the dialog units are multiplied by the average character width
307 and then divided by
4.
309 For the y dimension, the dialog units are multiplied by the average character height
310 and then divided by
8.
314 Dialog units are used for maintaining a dialog's proportions even if the font changes.
315 Dialogs created using Dialog Editor optionally use dialog units.
317 You can also use these functions programmatically. A convenience macro is defined:

528 anything if there are no subwindows and will only really work correctly if the
529 sizers are used for the subwindows layout. Also, if the window has exactly one
530 subwindow it is better (faster and the result is more precise as Fit adds some
531 margin to account for fuzziness of its calculations) to call

2369 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2370 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2371 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2372 value has to be adjusted when the window is resized, since the page size will have changed.
2374 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2375 the thumb changes size to reflect the page size relative to the length of the
document. When the
2376 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2377 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2434 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2435 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2436 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2437 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2438 and usually the scrollbar will be automatically hidden.

2551 Sets the window to have the given layout sizer. The window

2603 This function tells a window if it should use the system's "theme" code
2604 to draw the windows' background instead if its own background drawing
2605 code. This does not always have any effect since the underlying platform
2606 obviously needs to support the notion of themes in user defined windows.
2607 One such platform is GTK+ where windows can have (very colourful) backgrounds
2608 defined by a user's selected theme.
2610 Dialogs, notebook pages and the status bar have this flag set to true
2611 by default so that the default look and feel is simulated best.
