}}\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 only implemented for wxMSW 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.

\_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

\_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.

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

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

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

}
819 \func{static wxVisualAttributes
}{GetClassDefaultAttributes
}{\param{wxWindowVariant
}{ variant =

821 Returns the default font and colours which are used by the control. This is
822 useful if you want to use the same font or colour in your own control as in a
823 standard control -- which is a much better idea than hard coding specific
824 colours or fonts which might look completely out of place on the users
825 system, especially if it uses themes.
827 The
\arg{variant
} parameter is only relevant under Mac currently and is
828 ignore under other platforms. Under Mac, it will change the size of the
829 returned font. See
\helpref{wxWindow::SetWindowVariant
}{wxwindowsetwindowvariant
}
832 This static method is ``overridden'' in many derived classes and so calling,
833 for example,
\helpref{wxButton
}{wxbutton
}::GetClassDefaultAttributes() will typically
834 return the values appropriate for a button which will be normally different
835 from those returned by, say,
\helpref{wxListCtrl
}{wxlistctrl
}::GetClassDefaultAttributes().
837 The
\texttt{wxVisualAttributes
} structure has at least the fields
838 \texttt{font
},
\texttt{colFg
} and
\texttt{colBg
}. All of them may be invalid
839 if it was not possible to determine the default control appearance or,
840 especially for the background colour, if the field doesn't make sense as is

913 \helpref{GetClassDefaultAttributes
}{wxwindowgetclassdefaultattributes
}(
\helpref{GetWindowVariant
}{wxwindowgetwindowvariant

915 One advantage of using this function compared to the static version is that
916 the call is automatically dispatched to the correct class (as usual with
917 virtual functions) and you don't have to specify the class name explicitly.
919 The other one is that in the future this function could return different
920 results, for example it might return a different font for an ``Ok'' button
921 than for a generic button if the users GUI is configured to show such buttons
922 in bold font. Of course, the down side is that it is impossible to call this
923 function without actually having an object to apply it to whereas the static
924 version can be used without having to create an object first.

}{\void}
1375 This function is (or should be, in case of custom controls) called during
1376 window creation to intelligently set up the window visual attributes, that is
1377 the font and the foreground and background colours.
1379 By ``intelligently'' the following is meant: by default, all windows use their
1380 own
\helpref{default
}{wxwindowgetclassdefaultattributes
} attributes. However
1381 if some of the parents attributes are explicitly (that is, using
1382 \helpref{SetFont
}{wxwindowsetfont
} and not
1383 \helpref{SetOwnFont
}{wxwindowsetownfont
}) changed
\emph{and
} if the
1384 corresponding attribute hadn't been explicitly set for this window itself,
1385 then this window takes the same value as used by the parent. In addition, if
1386 the window overrides
\helpref{ShouldInheritColours
}{wxwindowshouldinheritcolours
}
1387 to return
\false, the colours will not be changed no matter what and only the
1390 This rather complicated logic is necessary in order to accommodate the
1391 different usage scenarios. The most common one is when all default attributes
1392 are used and in this case, nothing should be inherited as in modern GUIs
1393 different controls use different fonts (and colours) than their siblings so
1394 they can't inherit the same value from the parent. However it was also deemed
1395 desirable to allow to simply change the attributes of all children at once by
1396 just changing the font or colour of their common parent, hence in this case we
1397 do inherit the parents attributes.

3017 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3018 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3019 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3020 value has to be adjusted when the window is resized, since the page size will have changed.
3022 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3023 the thumb changes size to reflect the page size relative to the length of the
document. When the
3024 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3025 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

3085 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3086 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3087 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3088 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3089 and usually the scrollbar will be automatically hidden.

3274 This function tells a window if it should use the system's "theme" code
3275 to draw the windows' background instead if its own background drawing
3276 code. This does not always have any effect since the underlying platform
3277 obviously needs to support the notion of themes in user defined windows.
3278 One such platform is GTK+ where windows can have (very colourful) backgrounds
3279 defined by a user's selected theme.
3281 Dialogs, notebook pages and the status bar have this flag set to true
3282 by default so that the default look and feel is simulated best.

3499 flow of control returns to the event loop. Notice that this function doesn't
3500 refresh the window and does nothing if the window hadn't been already

}{\param{long
}{ flags = wxUPDATE

3509 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3510 the window. The particular implementation depends on the window; for
3511 example a wxToolBar will send an update UI event for each toolbar button,
3512 and a wxFrame will send an update UI event for each menubar menu item.
3513 You can call this function from your application to ensure that your
3514 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3515 are concerned). This may be necessary if you have called
3516 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3517 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3518 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3520 {\it flags
} should be a bitlist of one or more of the following values.
3525 wxUPDATE_UI_NONE =
0x0000, // No particular value
3526 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3527 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3531 If you are calling this function from an OnInternalIdle or OnIdle
3532 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3533 this tells the window to only update the UI elements that need
3534 to be updated in idle time. Some windows update their elements
3535 only when necessary, for example when a menu is about to be shown.
3536 The following is an example of how to call UpdateWindowUI from
3540 void MyWindow::OnInternalIdle()
