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

46 The following styles can apply to all windows, although they will not always make sense for a particular
47 window class or on all platforms.
50 \begin{twocollist
}\itemsep=
0pt
51 \twocolitem{\windowstyle{wxSIMPLE
\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
53 \twocolitem{\windowstyle{wxDOUBLE
\_BORDER}}{Displays a double border. Windows and Mac only.
}
54 \twocolitem{\windowstyle{wxSUNKEN
\_BORDER}}{Displays a sunken border.
}
55 \twocolitem{\windowstyle{wxRAISED
\_BORDER}}{Displays a raised border.
}
56 \twocolitem{\windowstyle{wxSTATIC
\_BORDER}}{Displays a border suitable for a static control. Windows only.
}
57 \twocolitem{\windowstyle{wxNO
\_BORDER}}{Displays no border, overriding the default border style for the window.
}
58 \twocolitem{\windowstyle{wxTRANSPARENT
\_WINDOW}}{The window is transparent, that is, it will not receive paint
59 events. Windows only.
}
60 \twocolitem{\windowstyle{wxTAB
\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.
}
61 \twocolitem{\windowstyle{wxWANTS
\_CHARS}}{Use this to indicate that
62 the window wants to get all char/key events for all keys - even for
63 keys like TAB or ENTER which are usually used for dialog navigation
64 and which wouldn't be generated without this style. If you need to
65 use this style in order to get the arrows or etc., but would still like to have
66 normal keyboard navigation take place, you should create and send a
67 wxNavigationKeyEvent in response to the key events for Tab and
69 \twocolitem{\windowstyle{wxNO
\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
70 the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
71 and no longer has an effect.
}
72 \twocolitem{\windowstyle{wxVSCROLL
}}{Use this style to enable a vertical scrollbar.
}
73 \twocolitem{\windowstyle{wxHSCROLL
}}{Use this style to enable a horizontal scrollbar.
}
74 \twocolitem{\windowstyle{wxALWAYS
\_SHOW\_SB}}{If a window has scrollbars,
75 disable them instead of hiding them when they are not needed (i.e. when the
76 size of the window is big enough to not require the scrollbars to navigate it).
77 This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
78 nothing on the other platforms.
}
79 \twocolitem{\windowstyle{wxCLIP
\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
80 repainted, then children being painted over them. Windows only.
}
81 \twocolitem{\windowstyle{wxFULL
\_REPAINT\_ON\_RESIZE}}{Use this style to force
82 a complete redraw of the window whenever it is resized instead of redrawing
83 just the part of the window affected by resizing. Note that this was the
84 behaviour by default before
2.5.1 release and that if you experience redraw
85 problems with code which previously used to work you may want to try this.
86 Currently this style applies on GTK+
2 and Windows only, and full repainting is always
87 done on other platforms.

101 \twocolitem{\windowstyle{wxWS
\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
102 parent window and so on recursively by default. Using this flag for the
103 given window allows to block this propagation at this window, i.e. prevent
104 the events from being propagated further upwards. Dialogs have this
106 \twocolitem{\windowstyle{wxWS
\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
107 be used with transient windows as otherwise there is the risk of creating a

109 parent is destroyed before the child.

349 This function simply generates a
\helpref{wxCloseEvent
}{wxcloseevent

350 handler usually tries to close the window. It doesn't close the window itself,
353 \wxheading{Parameters
}
355 \docparam{force
}{{\tt false
} if the window's close handler should be able to veto the destruction
356 of this window,
{\tt true
} if it cannot.
}
360 Close calls the
\helpref{close handler
}{wxcloseevent
} for the window, providing
361 an opportunity for the window to choose whether to destroy the window.
362 Usually it is only used with the top level windows (wxFrame and wxDialog
363 classes) as the others are not supposed to have any special OnClose() logic.
365 The close handler should check whether the window is being deleted forcibly,
366 using
\helpref{wxCloseEvent::CanVeto
}{wxcloseeventcanveto
}, in which case it
367 should destroy the window using
\helpref{wxWindow::Destroy
}{wxwindowdestroy
}.
369 {\it Note
} that calling Close does not guarantee that the window will be
370 destroyed; but it provides a way to simulate a manual close of a window, which
371 may or may not be implemented by destroying the window. The default
372 implementation of wxDialog::OnCloseWindow does not necessarily delete the
373 dialog, since it will simply simulate an wxID
\_CANCEL event which is handled by
374 the appropriate button event handler and may do anything at all.
376 To guarantee that the window will be destroyed, call

392 Converts a point or size from dialog units to pixels.
394 For the x dimension, the dialog units are multiplied by the average character width
395 and then divided by
4.
397 For the y dimension, the dialog units are multiplied by the average character height
398 and then divided by
8.
402 Dialog units are used for maintaining a dialog's proportions even if the font changes.
404 You can also use these functions programmatically. A convenience macro is defined:

472 have been processed. This prevents problems with events being sent to non-existent

836 Returns the default font and colours which are used by the control. This is
837 useful if you want to use the same font or colour in your own control as in a
838 standard control -- which is a much better idea than hard coding specific
839 colours or fonts which might look completely out of place on the users
840 system, especially if it uses themes.
842 The
\arg{variant

843 ignore under other platforms. Under Mac, it will change the size of the
844 returned font. See

847 This static method is ``overridden'' in many derived classes and so calling,
848 for example,
\helpref{wxButton

850 from those returned by, say,

933 One advantage of using this function compared to the static version is that
934 the call is automatically dispatched to the correct class (as usual with
935 virtual functions) and you don't have to specify the class name explicitly.
937 The other one is that in the future this function could return different
938 results, for example it might return a different font for an ``Ok'' button
939 than for a generic button if the users GUI is configured to show such buttons
940 in bold font. Of course, the down side is that it is impossible to call this
941 function without actually having an object to apply it to whereas the static

}{\void}
1478 This function is (or should be, in case of custom controls) called during
1479 window creation to intelligently set up the window visual attributes, that is
1480 the font and the foreground and background colours.
1482 By ``intelligently'' the following is meant: by default, all windows use their
1483 own
\helpref{default
}{wxwindowgetclassdefaultattributes
} attributes. However
1484 if some of the parents attributes are explicitly (that is, using
1485 \helpref{SetFont
}{wxwindowsetfont
} and not
1486 \helpref{SetOwnFont
}{wxwindowsetownfont
}) changed
\emph{and
} if the
1487 corresponding attribute hadn't been explicitly set for this window itself,
1488 then this window takes the same value as used by the parent. In addition, if
1489 the window overrides
\helpref{ShouldInheritColours
}{wxwindowshouldinheritcolours
}
1490 to return
\false, the colours will not be changed no matter what and only the
1493 This rather complicated logic is necessary in order to accommodate the
1494 different usage scenarios. The most common one is when all default attributes
1495 are used and in this case, nothing should be inherited as in modern GUIs
1496 different controls use different fonts (and colours) than their siblings so
1497 they can't inherit the same value from the parent. However it was also deemed
1498 desirable to allow to simply change the attributes of all children at once by
1499 just changing the font or colour of their common parent, hence in this case we
1500 do inherit the parents attributes.

3135 Let's say you wish to display
50 lines of text, using the same font.
3136 The window is sized so that you can only see
16 lines at a time.
3142 SetScrollbar(wxVERTICAL,
0,
16,
50);
3146 Note that with the window at this size, the thumb position can never go
3147 above
50 minus
16, or
34.
3149 You can determine how many lines are currently visible by dividing the current view
3150 size by the character height in pixels.
3152 When defining your own scrollbar behaviour, you will always need to recalculate
3153 the scrollbar settings when the window size changes. You could therefore put your
3154 scrollbar calculations and SetScrollbar
3155 call into a function named AdjustScrollbars, which can be called initially and also
3156 from your

3183 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3184 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3185 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3186 value has to be adjusted when the window is resized, since the page size will have changed.
3188 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3189 the thumb changes size to reflect the page size relative to the length of the
document. When the
3190 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3191 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3194 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3195 handling of pages and ranges.

3251 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3252 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3253 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3254 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3255 and usually the scrollbar will be automatically hidden.

3401 One such platform is GTK+ where windows can have (very colourful) backgrounds
3402 defined by a user's selected theme.
3404 Dialogs, notebook pages and the status bar have this flag set to true

3645 \func{virtual void
}{Update
}{\void}
3647 Calling this method immediately repaints the invalidated area of the window and
3648 all of its children recursively while this would usually only happen when the
3649 flow of control returns to the event loop.
3650 Notice that this function doesn't invalidate any area of the window so
3651 nothing happens if nothing has been invalidated (i.e. marked as requiring
3652 a redraw). Use
\helpref{Refresh
}{wxwindowrefresh
} first if you want to
3653 immediately redraw the window unconditionally.

}\label{wxwindowupdatewindowui
}
3658 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
3660 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3661 the window. The particular implementation depends on the window; for
3662 example a wxToolBar will send an update UI event for each toolbar button,
3663 and a wxFrame will send an update UI event for each menubar menu item.
3664 You can call this function from your application to ensure that your
3665 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3666 are concerned). This may be necessary if you have called
3667 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3668 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3669 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3671 {\it flags
} should be a bitlist of one or more of the following values.
3676 wxUPDATE_UI_NONE =
0x0000, // No particular value
3677 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3678 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3682 If you are calling this function from an OnInternalIdle or OnIdle
3683 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3684 this tells the window to only update the UI elements that need
3685 to be updated in idle time. Some windows update their elements
3686 only when necessary, for example when a menu is about to be shown.
3687 The following is an example of how to call UpdateWindowUI from
3691 void MyWindow::OnInternalIdle()
3693 if (wxUpdateUIEvent::CanUpdate(this))
3694 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);

}\label{wxwindowvalidate

3707 \func{virtual bool

3709 Validates the current values of the child controls using their validators.
3711 If the window has
{\tt wxWS
\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3712 the method will also call Validate() of all child windows.
3714 \wxheading{Return value
}
3716 Returns
{\tt false
} if any of the validations failed.
