}}\label{wxwindow
}
3 wxWindow is the base class for all windows and represents any visible objecto n
4 screen. All controls, top level windows and so on are windows. Sizers and
5 device contexts are not, however, as they don't appear on screen themselves.
7 Please note that all children of the window will be deleted automatically by
8 the destructor before the window itself is deleted which means that you don't
9 have to worry about deleting them manually. Please see the
\helpref{window
10 deletion overview
}{windowdeletionoverview
} for more information.
12 Also note that in this, and many others, wxWindows classes some
13 \texttt{GetXXX()
} methods may be overloaded (as, for example,
14 \helpref{GetSize
}{wxwindowgetsize
} or
15 \helpref{GetClientSize
}{wxwindowgetclientsize
}). In this case, the overloads
16 are non-virtual because having multiple virtual functions with the same name
17 results in a virtual function name hiding at the derived class level (in
18 English, this means that the derived class has to override all overloaded
19 variants if it overrides any of them). To allow overriding them in the derived
20 class, wxWindows uses a unique protected virtual
\texttt{DoGetXXX()
} method
21 and all
\texttt{GetXXX()
} ones are forwarded to it, so overriding the former
22 changes the behaviour of the latter.

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

\_WINDOW}}{The window is transparent, that is, it will not receive paint
49 events. Windows only.

50 \twocolitem{\windowstyle{wxTAB
\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.
}
51 \twocolitem{\windowstyle{wxWANTS
\_CHARS}}{Use this to indicate that the window
52 wants to get all char events - even for keys like TAB or ENTER which are

62 disable them instead of hiding them when they are not needed (i.e. when the
63 size of the window is big enough to not require the scrollbars to navigate it).
64 This style is currently only implemented for wxMSW and wxUniversal and does
65 nothing on the other platforms.
}
66 \twocolitem{\windowstyle{wxCLIP
\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
67 repainted, then children being painted over them. Windows only.
}
68 \twocolitem{\windowstyle{wxFULL
\_REPAINT\_ON\_RESIZE}}{Use this style to force
69 a complete redraw of the window whenever it is resized instead of redrawing
70 just the part of the window affected by resizing. Note that this was the
71 behaviour by default before
2.5.1 release and that if you experience redraw
72 problems with the code which previously used to work you may want to try this.

319 This function simply generates a

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

360 \func{wxSize

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

2562 Let's say you wish to display
50 lines of text, using the same font.
2563 The window is sized so that you can only see
16 lines at a time.
2569 SetScrollbar(wxVERTICAL,
0,
16,
50);
2573 Note that with the window at this size, the thumb position can never go
2574 above
50 minus
16, or
34.
2576 You can determine how many lines are currently visible by dividing the current view
2577 size by the character height in pixels.
2579 When defining your own scrollbar behaviour, you will always need to recalculate
2580 the scrollbar settings when the window size changes. You could therefore put your
2581 scrollbar calculations and SetScrollbar
2582 call into a function named AdjustScrollbars, which can be called initially and also
2583 from your
\helpref{wxSizeEvent

2608 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2609 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2610 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2611 value has to be adjusted when the window is resized, since the page size will have changed.
2613 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2614 the thumb changes size to reflect the page size relative to the length of the
document. When the
2615 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2616 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2619 Currently, this function should be called before SetPageRange, because of a quirk in the Windows

2675 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2676 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2677 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2678 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2679 and usually the scrollbar will be automatically hidden.

3040 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3041 the window. The particular implementation depends on the window; for
3042 example a wxToolBar will send an update UI event for each toolbar button,
3043 and a wxFrame will send an update UI event for each menubar menu item.
3044 You can call this function from your application to ensure that your
3045 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3046 are concerned). This may be necessary if you have called
3047 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3048 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval

3049 limit the overhead that wxWindows incurs by sending update UI events in idle time.
3051 {\it flags

3056 wxUPDATE_UI_NONE =
0x0000, // No particular value
3057 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3058 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3062 If you are calling this function from an OnInternalIdle or OnIdle
3063 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3064 this tells the window to only update the UI elements that need
3065 to be updated in idle time. Some windows update their elements
3066 only when necessary, for example when a menu is about to be shown.
