}}\label{wxwindow
}
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

25 The following styles can apply to all windows, although they will not always make sense for a particular
26 window class or on all platforms.

}\label{wxwindowclose

259 The purpose of this call is to provide a safer way of destroying a window than using
260 the
{\it delete
} operator.
262 \wxheading{Parameters
}
264 \docparam{force
}{FALSE if the window's close handler should be able to veto the destruction
265 of this window, TRUE if it cannot.
}
269 Close calls the
\helpref{close handler
}{wxcloseevent
} for the window, providing an opportunity for the window to
270 choose whether to destroy the window.
272 The close handler should check whether the window is being deleted forcibly,
273 using
\helpref{wxCloseEvent::GetForce
}{wxcloseeventgetforce
}, in which case it should
274 destroy the window using
\helpref{wxWindow::Destroy
}{wxwindowdestroy
}.
276 Applies to managed windows (wxFrame and wxDialog classes) only.
278 {\it Note
} that calling Close does not guarantee that the window will be destroyed; but it
279 provides a way to simulate a manual close of a window, which may or may not be implemented by
280 destroying the window. The default implementation of wxDialog::OnCloseWindow does not
281 necessarily delete the dialog, since it will simply simulate an wxID
\_CANCEL event which
282 itself only hides the dialog.
284 To guarantee that the window will be destroyed, call
\helpref{wxWindow::Destroy
}{wxwindowdestroy
} instead.

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

379 to a list of windows to be deleted on idle time, when all the window's events
380 have been processed. This prevents problems with events being sent to non-existant

16 lines at a time.

0,

2239 Note that with the window at this size, the thumb position can never go

2242 You can determine how many lines are currently visible by dividing the current view

2246 the scrollbar settings when the window size changes. You could therefore put your

2273 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2274 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2275 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2276 value has to be adjusted when the window is resized, since the page size will have changed.
2278 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2279 the thumb changes size to reflect the page size relative to the length of the
document. When the
2280 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2281 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2338 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2339 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2340 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2341 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
