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.

}
39 \twocolitem{\windowstyle{wxWANTS

53 nothing on the other platforms.
}
54 \twocolitem{\windowstyle{wxCLIP
\_CHILDREN}}{Use this style to eliminate flicker caused by the background being

57 a complete redraw of the window whenever it is resized instead of redrawing
58 just the part of the window affected by resizing. Note that this was the
59 behaviour by default before
2.5.1 release and that if you experience redraw
60 problems with the code which previously used to work you may want to try this.

307 This function simply generates a

308 handler usually tries to close the window. It doesn't close the window itself,
311 \wxheading{Parameters
}
313 \docparam{force
}{{\tt false
} if the window's close handler should be able to veto the destruction
314 of this window,
{\tt true
} if it cannot.
}
318 Close calls the
\helpref{close handler
}{wxcloseevent
} for the window, providing
319 an opportunity for the window to choose whether to destroy the window.
320 Usually it is only used with the top level windows (wxFrame and wxDialog
321 classes) as the others are not supposed to have any special OnClose() logic.
323 The close handler should check whether the window is being deleted forcibly,
324 using
\helpref{wxCloseEvent::GetForce
}{wxcloseeventgetforce
}, in which case it
325 should destroy the window using
\helpref{wxWindow::Destroy
}{wxwindowdestroy
}.
327 {\it Note
} that calling Close does not guarantee that the window will be
328 destroyed; but it provides a way to simulate a manual close of a window, which
329 may or may not be implemented by destroying the window. The default
330 implementation of wxDialog::OnCloseWindow does not necessarily delete the
331 dialog, since it will simply simulate an wxID
\_CANCEL event which is handled by
332 the appropriate button event handler and may do anything at all.

348 \func{wxSize

350 Converts a point or size from dialog units to pixels.
352 For the x dimension, the dialog units are multiplied by the average character width
353 and then divided by
4.
355 For the y dimension, the dialog units are multiplied by the average character height
356 and then divided by
8.
360 Dialog units are used for maintaining a dialog's proportions even if the font changes.
361 Dialogs created using Dialog Editor optionally use dialog units.
363 You can also use these functions programmatically. A convenience macro is defined:
367 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

2550 Let's say you wish to display
50 lines of text, using the same font.
2551 The window is sized so that you can only see
16 lines at a time.
2557 SetScrollbar(wxVERTICAL,
0,
16,
50);
2561 Note that with the window at this size, the thumb position can never go
2562 above
50 minus
16, or
34.
2564 You can determine how many lines are currently visible by dividing the current view
2565 size by the character height in pixels.
2567 When defining your own scrollbar behaviour, you will always need to recalculate
2568 the scrollbar settings when the window size changes. You could therefore put your
2569 scrollbar calculations and SetScrollbar
2570 call into a function named AdjustScrollbars, which can be called initially and also
2571 from your
\helpref{wxSizeEvent
}{wxsizeevent
} handler function.

2596 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2597 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2598 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2599 value has to be adjusted when the window is resized, since the page size will have changed.
2601 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2602 the thumb changes size to reflect the page size relative to the length of the
document. When the
2603 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2604 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2663 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2664 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2665 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2666 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2667 and usually the scrollbar will be automatically hidden.

3028 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3029 the window. The particular implementation depends on the window; for
3030 example a wxToolBar will send an update UI event for each toolbar button,
3031 and a wxFrame will send an update UI event for each menubar menu item.
3032 You can call this function from your application to ensure that your
3033 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3034 are concerned). This may be necessary if you have called
3035 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3036 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3037 limit the overhead that wxWindows incurs by sending update UI events in idle time.
3039 {\it flags
} should be a bitlist of one or more of the following values.
3044 wxUPDATE_UI_NONE =
0x0000, // No particular value
3045 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3046 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3050 If you are calling this function from an OnInternalIdle or OnIdle
3051 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3052 this tells the window to only update the UI elements that need
3053 to be updated in idle time. Some windows update their elements
3054 only when necessary, for example when a menu is about to be shown.
