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.

}
264 \docparam{force
}{{\tt FALSE
} if the window's close handler should be able to veto the destruction
265 of this window,
{\tt TRUE

}
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

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:

1978 tends to be more device-independent than

2298 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2299 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2300 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2301 value has to be adjusted when the window is resized, since the page size will have changed.
2303 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2304 the thumb changes size to reflect the page size relative to the length of the
document. When the
2305 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2306 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2363 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total

2365 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2366 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero

2427 The second form is a convenience for calling the first form with default
2428 x and y parameters, and must be used with non-default width and height values.
2430 The first form sets the position and optionally size, of the window.
2431 Parameters may be -
1 to indicate either that a default should be supplied
2432 by wxWindows, or that the current value of the dimension should be used.

}
2478 \func{void
}{SetSizer
}{\param{wxSizer*
}{sizer
},
\param{bool

2480 Sets the window to have the given layout sizer. The window
2481 will then own the object, and will take care of its deletion.
2482 If an existing layout constraints object is already owned by the
2483 window, it will be deleted if the deleteOld parameter is TRUE.
2485 Note that this function will also call
2486 \helpref{SetAutoLayout
}{wxwindowsetautolayout
} implicitly with
{\tt TRUE
}
2487 parameter if the
{\it sizer
}\/ is non-NULL and
{\tt FALSE
} otherwise.
2489 \wxheading{Parameters
}
2491 \docparam{sizer
}{The sizer to set. Pass NULL to disassociate and conditionally delete
2492 the window's sizer. See below.
}
2494 \docparam{deleteOld

2502 You must call
\helpref{wxWindow::SetAutoLayout
}{wxwindowsetautolayout
} to tell a window to use
2503 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
2504 explicitly. When setting both a wxSizer and a
\helpref{wxLayoutConstraints

2505 only the sizer will have effect.

}{\param{bool

2532 This function tells a window if it should use the system's "theme" code
2533 to draw the windows' background instead if its own background drawing
2534 code. This does not always have any effect since the underlying platform
2535 obviously needs to support the notion of themes in user defined windows.
2536 One such platform is GTK+ where windows can have (very colourful) backgrounds
2537 defined by a user's selected theme.
2539 Dialogs, notebook pages and the status bar have this flag set to TRUE
2540 by default so that the default look and feel is simulated best.
