}}\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.

50 The following styles can apply to all windows, although they will not always make sense for a particular
51 window class or on all platforms.
54 \begin{twocollist
}\itemsep=
0pt
55 \twocolitem{\windowstyle{wxBORDER
\_DEFAULT}}{The window class will decide the kind of border to show, if any.
}
56 \twocolitem{\windowstyle{wxBORDER
\_SIMPLE}}{Displays a thin border around the window. wxSIMPLE
\_BORDER is the old name
58 \twocolitem{\windowstyle{wxBORDER
\_SUNKEN}}{Displays a sunken border. wxSUNKEN
\_BORDER is the old name for this style.
}
59 \twocolitem{\windowstyle{wxBORDER
\_RAISED}}{Displays a raised border. wxRAISED
\_BORDER is the old name for this style.
}
60 \twocolitem{\windowstyle{wxBORDER
\_STATIC}}{Displays a border suitable for a static control. wxSTATIC
\_BORDER is the old name for this style. Windows only.
}
61 \twocolitem{\windowstyle{wxBORDER
\_THEME}}{Displays a native border suitable for a control, on the current platform. On Windows XP or Vista, this will be a themed border; on most other platforms
62 a sunken border will be used. For more information for themed borders on Windows, please see
\helpref{Themed borders on Windows
}{wxmswthemedborders
}.
}
63 \twocolitem{\windowstyle{wxBORDER
\_NONE}}{Displays no border, overriding the default border style for the window. wxNO
\_BORDER is the old name for this style.
}
64 \twocolitem{\windowstyle{wxBORDER
\_DOUBLE}}{This style is obsolete and should not be used.
}
65 \twocolitem{\windowstyle{wxTRANSPARENT
\_WINDOW}}{The window is transparent, that is, it will not receive paint
66 events. Windows only.
}
67 \twocolitem{\windowstyle{wxTAB
\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.
}
68 \twocolitem{\windowstyle{wxWANTS
\_CHARS}}{Use this to indicate that
69 the window wants to get all char/key events for all keys - even for
70 keys like TAB or ENTER which are usually used for dialog navigation
71 and which wouldn't be generated without this style. If you need to
72 use this style in order to get the arrows or etc., but would still like
73 to have normal keyboard navigation take place, you should call
74 \helpref{Navigate
}{wxwindownavigate
} in response to the key events for
76 \twocolitem{\windowstyle{wxNO
\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
77 the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
78 and no longer has an effect.
}
79 \twocolitem{\windowstyle{wxVSCROLL
}}{Use this style to enable a vertical
80 scrollbar. Notice that this style cannot be used with native controls
81 which don't support scrollbars nor with top-level windows in most ports.
}
82 \twocolitem{\windowstyle{wxHSCROLL
}}{Use this style to enable a horizontal
83 scrollbar. The same limitations as for wxVSCROLL apply to this style.
}
84 \twocolitem{\windowstyle{wxALWAYS
\_SHOW\_SB}}{If a window has scrollbars,
85 disable them instead of hiding them when they are not needed (i.e. when the
86 size of the window is big enough to not require the scrollbars to navigate it).
87 This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
88 nothing on the other platforms.
}
89 \twocolitem{\windowstyle{wxCLIP
\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
90 repainted, then children being painted over them. Windows only.
}
91 \twocolitem{\windowstyle{wxFULL
\_REPAINT\_ON\_RESIZE}}{Use this style to force
92 a complete redraw of the window whenever it is resized instead of redrawing
93 just the part of the window affected by resizing. Note that this was the
94 behaviour by default before
2.5.1 release and that if you experience redraw
95 problems with code which previously used to work you may want to try this.
96 Currently this style applies on GTK+
2 and Windows only, and full repainting is always
97 done on other platforms.

\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
117 be used with transient windows as otherwise there is the risk of creating a

119 parent is destroyed before the child.

267 and when the mouse is released the capture returns to the window which had had
268 captured it previously and it is only really released if there were no previous
269 window. In particular, this means that you must release the mouse as many times
270 as you capture it, unless the window receives
271 the

410 \func{bool

412 This function simply generates a
\helpref{wxCloseEvent
}{wxcloseevent
} whose
413 handler usually tries to close the window. It doesn't close the window itself,
416 \wxheading{Parameters
}
418 \docparam{force
}{{\tt false
} if the window's close handler should be able to veto the destruction
419 of this window,
{\tt true
} if it cannot.
}
423 Close calls the
\helpref{close handler
}{wxcloseevent
} for the window, providing
424 an opportunity for the window to choose whether to destroy the window.
425 Usually it is only used with the top level windows (wxFrame and wxDialog
426 classes) as the others are not supposed to have any special OnClose() logic.
428 The close handler should check whether the window is being deleted forcibly,
429 using
\helpref{wxCloseEvent::CanVeto
}{wxcloseeventcanveto
}, in which case it
430 should destroy the window using
\helpref{wxWindow::Destroy
}{wxwindowdestroy
}.
432 {\it Note
} that calling Close does not guarantee that the window will be
433 destroyed; but it provides a way to simulate a manual close of a window, which
434 may or may not be implemented by destroying the window. The default
435 implementation of wxDialog::OnCloseWindow does not necessarily delete the
436 dialog, since it will simply simulate an wxID
\_CANCEL event which is handled by
437 the appropriate button event handler and may do anything at all.

455 Converts a point or size from dialog units to pixels.
457 For the x dimension, the dialog units are multiplied by the average character width
458 and then divided by
4.
460 For the y dimension, the dialog units are multiplied by the average character height
461 and then divided by
8.
465 Dialog units are used for maintaining a dialog's proportions even if the font changes.
467 You can also use these functions programmatically. A convenience macro is defined:

912 Returns the default font and colours which are used by the control. This is
913 useful if you want to use the same font or colour in your own control as in a
914 standard control -- which is a much better idea than hard coding specific
915 colours or fonts which might look completely out of place on the users
916 system, especially if it uses themes.

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

925 return the values appropriate for a button which will be normally different
926 from those returned by, say,

\helpref{GetWindowVariant
}{wxwindowgetwindowvariant

1009 One advantage of using this function compared to the static version is that
1010 the call is automatically dispatched to the correct class (as usual with
1011 virtual functions) and you don't have to specify the class name explicitly.
1013 The other one is that in the future this function could return different
1014 results, for example it might return a different font for an ``Ok'' button
1015 than for a generic button if the users GUI is configured to show such buttons
1016 in bold font. Of course, the down side is that it is impossible to call this
1017 function without actually having an object to apply it to whereas the static

}{\void}
1593 This function is (or should be, in case of custom controls) called during
1594 window creation to intelligently set up the window visual attributes, that is
1595 the font and the foreground and background colours.
1597 By ``intelligently'' the following is meant: by default, all windows use their
1598 own
\helpref{default
}{wxwindowgetclassdefaultattributes
} attributes. However
1599 if some of the parents attributes are explicitly (that is, using
1600 \helpref{SetFont
}{wxwindowsetfont
} and not
1601 \helpref{SetOwnFont
}{wxwindowsetownfont
}) changed
\emph{and
} if the
1602 corresponding attribute hadn't been explicitly set for this window itself,
1603 then this window takes the same value as used by the parent. In addition, if
1604 the window overrides
\helpref{ShouldInheritColours
}{wxwindowshouldinheritcolours
}
1605 to return
\false, the colours will not be changed no matter what and only the
1608 This rather complicated logic is necessary in order to accommodate the
1609 different usage scenarios. The most common one is when all default attributes
1610 are used and in this case, nothing should be inherited as in modern GUIs
1611 different controls use different fonts (and colours) than their siblings so
1612 they can't inherit the same value from the parent. However it was also deemed
1613 desirable to allow to simply change the attributes of all children at once by
1614 just changing the font or colour of their common parent, hence in this case we
1615 do inherit the parents attributes.

16 lines at a time.
3324 SetScrollbar(wxVERTICAL,
0,

3328 Note that with the window at this size, the thumb position can never go

3334 When defining your own scrollbar behaviour, you will always need to recalculate
3335 the scrollbar settings when the window size changes. You could therefore put your

3365 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3366 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3367 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3368 value has to be adjusted when the window is resized, since the page size will have changed.
3370 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3371 the thumb changes size to reflect the page size relative to the length of the
document. When the
3372 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3373 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

3433 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3434 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3435 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3436 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3437 and usually the scrollbar will be automatically hidden.

3692 This function can be called under all platforms but only does anything under
3693 Mac OS X
10.3+ currently. Under this system, each of the standard control can
3694 exist in several sizes which correspond to the elements of wxWindowVariant
3697 enum wxWindowVariant
3699 wxWINDOW_VARIANT_NORMAL, // Normal size
3700 wxWINDOW_VARIANT_SMALL, // Smaller size (about

33 % smaller than normal )
3702 wxWINDOW_VARIANT_LARGE, // Large size (about
25 % larger than normal )
3706 By default the controls use the normal size, of course, but this function can
3707 be used to change this.

3839 \membersection{wxWindow::Update
}\label{wxwindowupdate

3841 \func{virtual void
}{Update
}{\void}
3843 Calling this method immediately repaints the invalidated area of the window and
3844 all of its children recursively while this would usually only happen when the
3845 flow of control returns to the event loop.
3846 Notice that this function doesn't invalidate any area of the window so
3847 nothing happens if nothing has been invalidated (i.e. marked as requiring
3848 a redraw). Use
\helpref{Refresh
}{wxwindowrefresh
} first if you want to
3849 immediately redraw the window unconditionally.
3852 \membersection{wxWindow::UpdateWindowUI
}\label{wxwindowupdatewindowui
}
3854 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
3856 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3857 the window. The particular implementation depends on the window; for
3858 example a wxToolBar will send an update UI event for each toolbar button,
3859 and a wxFrame will send an update UI event for each menubar menu item.
3860 You can call this function from your application to ensure that your
3861 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3862 are concerned). This may be necessary if you have called
3863 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3864 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3865 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3867 {\it flags
} should be a bitlist of one or more of the following values.
3872 wxUPDATE_UI_NONE =
0x0000, // No particular value
3873 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3874 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3878 If you are calling this function from an OnInternalIdle or OnIdle
3879 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3880 this tells the window to only update the UI elements that need
3881 to be updated in idle time. Some windows update their elements
3882 only when necessary, for example when a menu is about to be shown.
3883 The following is an example of how to call UpdateWindowUI from
3887 void MyWindow::OnInternalIdle()
3889 if (wxUpdateUIEvent::CanUpdate(this))
3890 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
