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

259 This function simply generates a

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

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

527 subwindow it is better (faster and the result is more precise as Fit adds some

2366 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2367 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2368 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2369 value has to be adjusted when the window is resized, since the page size will have changed.
2371 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2372 the thumb changes size to reflect the page size relative to the length of the
document. When the
2373 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2374 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2433 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2434 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2435 and usually the scrollbar will be automatically hidden.

2600 This function tells a window if it should use the system's "theme" code
2601 to draw the windows' background instead if its own background drawing
2602 code. This does not always have any effect since the underlying platform
2603 obviously needs to support the notion of themes in user defined windows.
2604 One such platform is GTK+ where windows can have (very colourful) backgrounds
2605 defined by a user's selected theme.
2607 Dialogs, notebook pages and the status bar have this flag set to true
2608 by default so that the default look and feel is simulated best.
