}}\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\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the

114 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
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
\helpref{wxMouseCaptureLostEvent

387 Converts client area size
\arg{size

388 words, the returned value is what would
\helpref{GetSize
}{wxwindowgetsize
}
389 return if this window had client area of given size.
390 Components with $wxDefaultCoord$ value are left unchanged.
392 Note that the conversion is not always exact, it assumes that non-client area
393 doesn't change and so doesn't take into account things like menu bar
394 (un)wrapping or (dis)appearance of the scrollbars.

403 \func{bool

}{\param{bool
}{ force =
{\tt false

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

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

905 \func{static wxVisualAttributes

907 Returns the default font and colours which are used by the control. This is
908 useful if you want to use the same font or colour in your own control as in a
909 standard control -- which is a much better idea than hard coding specific
910 colours or fonts which might look completely out of place on the users
911 system, especially if it uses themes.
913 The
\arg{variant
} parameter is only relevant under Mac currently and is
914 ignore under other platforms. Under Mac, it will change the size of the
915 returned font. See
\helpref{wxWindow::SetWindowVariant
}{wxwindowsetwindowvariant
}
918 This static method is ``overridden'' in many derived classes and so calling,
919 for example,
\helpref{wxButton
}{wxbutton
}::GetClassDefaultAttributes() will typically
920 return the values appropriate for a button which will be normally different
921 from those returned by, say,

925 if it was not possible to determine the default control appearance or,

1001 Currently this is the same as calling
1002 \helpref{GetClassDefaultAttributes
}{wxwindowgetclassdefaultattributes
}(
\helpref{GetWindowVariant
}{wxwindowgetwindowvariant
}()).
1004 One advantage of using this function compared to the static version is that
1005 the call is automatically dispatched to the correct class (as usual with
1006 virtual functions) and you don't have to specify the class name explicitly.
1008 The other one is that in the future this function could return different
1009 results, for example it might return a different font for an ``Ok'' button
1010 than for a generic button if the users GUI is configured to show such buttons
1011 in bold font. Of course, the down side is that it is impossible to call this
1012 function without actually having an object to apply it to whereas the static
1013 version can be used without having to create an object first.

1706 \func{void
}{InheritAttributes
}{\void}
1708 This function is (or should be, in case of custom controls) called during
1709 window creation to intelligently set up the window visual attributes, that is
1710 the font and the foreground and background colours.
1712 By ``intelligently'' the following is meant: by default, all windows use their
1713 own
\helpref{default
}{wxwindowgetclassdefaultattributes
} attributes. However
1714 if some of the parents attributes are explicitly (that is, using
1715 \helpref{SetFont
}{wxwindowsetfont
} and not
1716 \helpref{SetOwnFont
}{wxwindowsetownfont
}) changed
\emph{and
} if the
1717 corresponding attribute hadn't been explicitly set for this window itself,
1718 then this window takes the same value as used by the parent. In addition, if
1719 the window overrides
\helpref{ShouldInheritColours
}{wxwindowshouldinheritcolours
}
1720 to return
\false, the colours will not be changed no matter what and only the
1723 This rather complicated logic is necessary in order to accommodate the
1724 different usage scenarios. The most common one is when all default attributes
1725 are used and in this case, nothing should be inherited as in modern GUIs
1726 different controls use different fonts (and colours) than their siblings so
1727 they can't inherit the same value from the parent. However it was also deemed
1728 desirable to allow to simply change the attributes of all children at once by
1729 just changing the font or colour of their common parent, hence in this case we
1730 do inherit the parents attributes.

3519 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3520 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3521 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3522 value has to be adjusted when the window is resized, since the page size will have changed.
3524 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3525 the thumb changes size to reflect the page size relative to the length of the
document. When the
3526 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3527 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

3587 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3588 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3589 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3590 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3591 and usually the scrollbar will be automatically hidden.

3646 {\bf wxSIZE
\_ALLOW\_MINUS\_ONE}: allow negative dimensions (i.e. value of $wxDefaultCoord$) to be interpreted
3647 as real dimensions, not default values.
3648 {\bf wxSIZE

3649 already the same as the parameters of this function, nothing is done. but with
3650 this flag a window resize may be forced even in this case (supported in wx
3651 2.6.2 and later and only implemented for MSW and ignored elsewhere currently)
3656 The second form is a convenience for calling the first form with default
3657 x and y parameters, and must be used with non-default width and height values.
3659 The first form sets the position and optionally size, of the window.
3660 Parameters may be $wxDefaultCoord$ to indicate either that a default should be supplied
3661 by wxWidgets, or that the current value of the dimension should be used.

3697 Sets the window to have the given layout sizer. The window
3698 will then own the object, and will take care of its deletion.
3699 If an existing layout constraints object is already owned by the
3700 window, it will be deleted if the deleteOld parameter is true.
3702 Note that this function will also call
3703 \helpref{SetAutoLayout

{\tt true

3704 parameter if the

3729 This method calls
\helpref{SetSizer

3730 \helpref{wxSizer::SetSizeHints
}{wxsizersetsizehints
} which sets the initial
3731 window size to the size needed to accommodate all sizer elements and sets the

3740 This function tells a window if it should use the system's "theme" code
3741 to draw the windows' background instead if its own background drawing
3742 code. This does not always have any effect since the underlying platform
3743 obviously needs to support the notion of themes in user defined windows.
3744 One such platform is GTK+ where windows can have (very colourful) backgrounds
3745 defined by a user's selected theme.
3747 Dialogs, notebook pages and the status bar have this flag set to true
3748 by default so that the default look and feel is simulated best.

3853 This function can be called under all platforms but only does anything under

4056 Calling this method immediately repaints the invalidated area of the window and
4057 all of its children recursively while this would usually only happen when the
4058 flow of control returns to the event loop.
4059 Notice that this function doesn't invalidate any area of the window so
4060 nothing happens if nothing has been invalidated (i.e. marked as requiring
4061 a redraw). Use
\helpref{Refresh

}\label{wxwindowupdatewindowui

4067 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
4069 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
4070 the window. The particular implementation depends on the window; for
4071 example a wxToolBar will send an update UI event for each toolbar button,
4072 and a wxFrame will send an update UI event for each menubar menu item.
4073 You can call this function from your application to ensure that your
4074 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
4075 are concerned). This may be necessary if you have called
4076 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
4077 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
4078 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
4080 {\it flags
} should be a bitlist of one or more of the following values.
4085 wxUPDATE_UI_NONE =
0x0000, // No particular value
4086 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
4087 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
4091 If you are calling this function from an OnInternalIdle or OnIdle
4092 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
4093 this tells the window to only update the UI elements that need
4094 to be updated in idle time. Some windows update their elements
4095 only when necessary, for example when a menu is about to be shown.
4096 The following is an example of how to call UpdateWindowUI from
4100 void MyWindow::OnInternalIdle()
4102 if (wxUpdateUIEvent::CanUpdate(this))
