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

}\label{wxwindowclose

284 \func{bool

}{ force =

286 This function simply generates a
\helpref{wxCloseEvent
}{wxcloseevent
} whose
287 handler usually tries to close the window. It doesn't close the window itself,
290 \wxheading{Parameters
}
292 \docparam{force
}{{\tt false
} if the window's close handler should be able to veto the destruction
293 of this window,
{\tt true
} if it cannot.
}
297 Close calls the
\helpref{close handler
}{wxcloseevent
} for the window, providing
298 an opportunity for the window to choose whether to destroy the window.
299 Usually it is only used with the top level windows (wxFrame and wxDialog
300 classes) as the others are not supposed to have any special OnClose() logic.
302 The close handler should check whether the window is being deleted forcibly,
303 using
\helpref{wxCloseEvent::GetForce
}{wxcloseeventgetforce
}, in which case it
304 should destroy the window using
\helpref{wxWindow::Destroy
}{wxwindowdestroy
}.
306 {\it Note
} that calling Close does not guarantee that the window will be
307 destroyed; but it provides a way to simulate a manual close of a window, which
308 may or may not be implemented by destroying the window. The default
309 implementation of wxDialog::OnCloseWindow does not necessarily delete the
310 dialog, since it will simply simulate an wxID
\_CANCEL event which is handled by
311 the appropriate button event handler and may do anything at all.
313 To guarantee that the window will be destroyed, call
314 \helpref{wxWindow::Destroy
}{wxwindowdestroy

}{\param{const wxPoint\&

}}
326 \func{wxSize
}{ConvertDialogToPixels
}{\param{const wxSize\&

328 Converts a point or size from dialog units to pixels.
330 For the x dimension, the dialog units are multiplied by the average character width
331 and then divided by
4.
333 For the y dimension, the dialog units are multiplied by the average character height
334 and then divided by
8.
338 Dialog units are used for maintaining a dialog's proportions even if the font changes.
339 Dialogs created using Dialog Editor optionally use dialog units.
341 You can also use these functions programmatically. A convenience macro is defined:
345 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

406 Destroys the window safely. Use this function instead of the delete operator, since
407 different window classes can be destroyed differently. Frames and dialogs
408 are not destroyed immediately when this function is called -- they are added
409 to a list of windows to be deleted on idle time, when all the window's events
410 have been processed. This prevents problems with events being sent to non-existent

577 anything if there are no subwindows and will only really work correctly if the
578 sizers are used for the subwindows layout. Also, if the window has exactly one
579 subwindow it is better (faster and the result is more precise as Fit adds some

2433 You can determine how many lines are currently visible by dividing the current view
2434 size by the character height in pixels.
2436 When defining your own scrollbar behaviour, you will always need to recalculate
2437 the scrollbar settings when the window size changes. You could therefore put your
2438 scrollbar calculations and SetScrollbar
2439 call into a function named AdjustScrollbars, which can be called initially and also
2440 from your
\helpref{wxSizeEvent

2464 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2465 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2466 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2467 value has to be adjusted when the window is resized, since the page size will have changed.
2469 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2470 the thumb changes size to reflect the page size relative to the length of the
document. When the
2471 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2472 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2529 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2530 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2531 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2532 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2533 and usually the scrollbar will be automatically hidden.

2875 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
2876 the window. The particular implementation depends on the window; for
2877 example a wxToolBar will send an update UI event for each toolbar button,
2878 and a wxFrame will send an update UI event for each menubar menu item.
2879 You can call this function from your application to ensure that your
2880 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
2881 are concerned). This may be necessary if you have called
2882 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
2883 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
2884 limit the overhead that wxWindows incurs by sending update UI events in idle time.
2886 {\it flags
} should be a bitlist of one or more of the following values.
2891 wxUPDATE_UI_NONE =
0x0000, // No particular value
2892 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
2893 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
2897 If you are calling this function from an OnInternalIdle or OnIdle
2898 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
2899 this tells the window to only update the UI elements that need
2900 to be updated in idle time. Some windows update their elements
2901 only when necessary, for example when a menu is about to be shown.
2902 The following is an example of how to call UpdateWindowUI from
