}}\label{wxwindow
}
3 wxWindow is the base class for all windows and represents any visible object on
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, wxWidgets 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, wxWidgets 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.

35 The following styles can apply to all windows, although they will not always make sense for a particular
36 window class or on all platforms.
39 \begin{twocollist

40 \twocolitem{\windowstyle{wxSIMPLE
\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
42 \twocolitem{\windowstyle{wxDOUBLE

\_BORDER}}{Displays a sunken border.
}
44 \twocolitem{\windowstyle{wxRAISED

}
45 \twocolitem{\windowstyle{wxSTATIC
\_BORDER}}{Displays a border suitable for a static control. Windows only.
}
46 \twocolitem{\windowstyle{wxNO
\_BORDER}}{Displays no border, overriding the default border style for the window.
}
47 \twocolitem{\windowstyle{wxTRANSPARENT
\_WINDOW}}{The window is transparent, that is, it will not receive paint
48 events. Windows only.
}
49 \twocolitem{\windowstyle{wxTAB
\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.
}
50 \twocolitem{\windowstyle{wxWANTS
\_CHARS}}{Use this to indicate that
51 the window wants to get all char/key events for all keys - even for
52 keys like TAB or ENTER which are usually used for dialog navigation
53 and which wouldn't be generated without this style. If you need to
54 use this style in order to get the arrows or etc., but would still like to have
55 normal keyboard navigation take place, you should create and send a
56 wxNavigationKeyEvent in response to the key events for Tab and
58 \twocolitem{\windowstyle{wxNO
\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
59 the window completely when its size is changed - you will have to repaint the

}
63 \twocolitem{\windowstyle{wxHSCROLL

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

322 This function simply generates a

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

365 Converts a point or size from dialog units to pixels.
367 For the x dimension, the dialog units are multiplied by the average character width
368 and then divided by
4.
370 For the y dimension, the dialog units are multiplied by the average character height
371 and then divided by
8.
375 Dialog units are used for maintaining a dialog's proportions even if the font changes.
377 You can also use these functions programmatically. A convenience macro is defined:

626 sizers are used for the subwindows layout. Also, if the window has exactly one
627 subwindow it is better (faster and the result is more precise as Fit adds some
628 margin to account for fuzziness of its calculations) to call
631 window->SetClientSize(child->GetSize());
634 instead of calling Fit.

792 Returns the default font and colours which are used by the control. This is
793 useful if you want to use the same font or colour in your own control as in a
794 standard control -- which is a much better idea than hard coding specific
795 colours or fonts which might look completely out of place on the users
796 system, especially if it uses themes.
798 The
\arg{variant
} parameter is only relevant under Mac currently and is
799 ignore under other platforms. Under Mac, it will change the size of the
800 returned font. See
\helpref{wxWindow::SetWindowVariant
}{wxwindowsetwindowvariant

803 This static method is ``overridden'' in many derived classes and so calling,
804 for example,
\helpref{wxButton
}{wxbutton
}::GetClassDefaultAttributes() will typically
805 return the values appropriate for a button which will be normally different
806 from those returned by, say,
\helpref{wxListCtrl
}{wxlistctrl
}::GetClassDefaultAttributes().
808 The
\texttt{wxVisualAttributes
} structure has at least the fields
809 \texttt{font
},
\texttt{colFg
} and
\texttt{colBg
}. All of them may be invalid
810 if it was not possible to determine the default control appearance or,
811 especially for the background colour, if the field doesn't make sense as is
812 the case for
\texttt{colBg

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

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

1303 \membersection{wxWindow::InheritAttributes
}\label{wxwindowinheritattributes
}
1305 \func{void
}{InheritAttributes
}{\void}
1307 This function is (or should be, in case of custom controls) called during
1308 window creation to intelligently set up the window visual attributes, that is
1309 the font and the foreground and background colours.
1311 By ``intelligently'' the following is meant: by default, all windows use their
1312 own
\helpref{default
}{wxwindowgetclassdefaultattributes
} attributes. However
1313 if some of the parents attributes are explicitly (that is, using
1314 \helpref{SetFont
}{wxwindowsetfont
} and not
1315 \helpref{SetOwnFont
}{wxwindowsetownfont
}) changed
\emph{and
} if the
1316 corresponding attribute hadn't been explicitly set for this window itself,
1317 then this window takes the same value as used by the parent. In addition, if
1318 the window overrides
\helpref{ShouldInheritColours
}{wxwindowshouldinheritcolours
}
1319 to return
\false, the colours will not be changed no matter what and only the
1322 This rather complicated logic is necessary in order to accomodate the
1323 different usage scenarius. The most common one is when all default attributes
1324 are used and in this case, nothing should be inherited as in modern GUIs
1325 different controls use different fonts (and colours) than their siblings so
1326 they can't inherit the same value from the parent. However it was also deemed
1327 desirable to allow to simply change the attributes of all children at once by
1328 just changing the font or colour of their common parent, hence in this case we
1329 do inherit the parents attributes.

2851 Let's say you wish to display
50 lines of text, using the same font.
2852 The window is sized so that you can only see
16 lines at a time.
2858 SetScrollbar(wxVERTICAL,
0,
16,
50);
2862 Note that with the window at this size, the thumb position can never go

50 minus
16, or
34.
2865 You can determine how many lines are currently visible by dividing the current view
2866 size by the character height in pixels.
2868 When defining your own scrollbar behaviour, you will always need to recalculate
2869 the scrollbar settings when the window size changes. You could therefore put your
2870 scrollbar calculations and SetScrollbar
2871 call into a function named AdjustScrollbars, which can be called initially and also

2898 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2899 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2900 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2901 value has to be adjusted when the window is resized, since the page size will have changed.
2903 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2904 the thumb changes size to reflect the page size relative to the length of the
document. When the
2905 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2906 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2966 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2967 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2968 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2969 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero

3092 \membersection{wxWindow::SetSizer
}\label{wxwindowsetsizer
}
3094 \func{void
}{SetSizer
}{\param{wxSizer*
}{sizer
},
\param{bool
}{deleteOld=true
}}
3096 Sets the window to have the given layout sizer. The window
3097 will then own the object, and will take care of its deletion.
3098 If an existing layout constraints object is already owned by the
3099 window, it will be deleted if the deleteOld parameter is true.
3101 Note that this function will also call
3102 \helpref{SetAutoLayout
}{wxwindowsetautolayout
} implicitly with
{\tt true
}
3103 parameter if the
{\it sizer
}\/ is non-NULL and
{\tt false
} otherwise.
3105 \wxheading{Parameters
}
3107 \docparam{sizer
}{The sizer to set. Pass NULL to disassociate and conditionally delete
3108 the window's sizer. See below.
}
3110 \docparam{deleteOld
}{If true (the default), this will delete any prexisting sizer.
3111 Pass false if you wish to handle deleting the old sizer yourself.
}
3115 SetSizer now enables and disables Layout automatically, but prior to wxWidgets
2.3.3
3116 the following applied:
3118 You must call
\helpref{wxWindow::SetAutoLayout
}{wxwindowsetautolayout
} to tell a window to use
3119 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3120 explicitly. When setting both a wxSizer and a
\helpref{wxLayoutConstraints
}{wxlayoutconstraints
},
3121 only the sizer will have effect.

}\label{wxwindowsetsizerandfit
}
3126 \func{void
}{SetSizerAndFit
}{\param{wxSizer*

},
\param{bool

3128 The same as
\helpref{SetSizer
}{wxwindowsetsizer
}, except it also sets the size hints
3129 for the window based on the sizer's minimum size.
3132 \membersection{wxWindow::SetTitle

3147 \membersection{wxWindow::SetThemeEnabled
}\label{wxwindowsetthemeenabled
}
3149 \func{virtual void
}{SetThemeEnabled
}{\param{bool
}{enable
}}
3151 This function tells a window if it should use the system's "theme" code
3152 to draw the windows' background instead if its own background drawing
3153 code. This does not always have any effect since the underlying platform
3154 obviously needs to support the notion of themes in user defined windows.
3155 One such platform is GTK+ where windows can have (very colourful) backgrounds
3156 defined by a user's selected theme.
3158 Dialogs, notebook pages and the status bar have this flag set to true
3159 by default so that the default look and feel is simulated best.

3247 \func{void
}{SetWindowVariant
}{\param{wxWindowVariant
}{variant
}}
3249 This function can be called under all platforms but only does anything under
3250 Mac OS X
10.3+ currently. Under this system, each of the standard control can
3251 exist in several sizes which correpond to the elements of wxWindowVariant
3254 enum wxWindowVariant
3256 wxWINDOW_VARIANT_NORMAL, // Normal size
3257 wxWINDOW_VARIANT_SMALL, // Smaller size (about
25 % smaller than normal )
3258 wxWINDOW_VARIANT_MINI, // Mini size (about
33 % smaller than normal )
3259 wxWINDOW_VARIANT_LARGE, // Large size (about
25 % larger than normal )
3263 By default the controls use the normal size, of course, but this function can
3264 be used to change this.

\true.
3279 \membersection{wxWindow::Show
}\label{wxwindowshow
}
3281 \func{virtual bool
}{Show
}{\param{bool
}{ show =

3283 Shows or hides the window. You may need to call
\helpref{Raise

}
3284 for a top level window if you want to bring it to top, although this is not
3285 needed if Show() is called immediately after the frame creation.

3369 \membersection{wxWindow::Update
}\label{wxwindowupdate

3371 \func{virtual void
}{Update
}{\void}
3373 Calling this method immediately repaints the invalidated area of the window
3374 while this would usually only happen when the flow of control returns to the
3375 event loop. Notice that this function doesn't refresh the window and does
3376 nothing if the window hadn't been already repainted. Use
3377 \helpref{Refresh
}{wxwindowrefresh
} first if you want to immediately redraw the
3378 window unconditionally.
3381 \membersection{wxWindow::UpdateWindowUI
}\label{wxwindowupdatewindowui
}
3383 \func{virtual void
}{UpdateWindowUI
}{\param{long
}{ flags = wxUPDATE
\_UI\_NONE}}
3385 This function sends
\helpref{wxUpdateUIEvents
}{wxupdateuievent
} to
3386 the window. The particular implementation depends on the window; for
3387 example a wxToolBar will send an update UI event for each toolbar button,
3388 and a wxFrame will send an update UI event for each menubar menu item.
3389 You can call this function from your application to ensure that your
3390 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3391 are concerned). This may be necessary if you have called
3392 \helpref{wxUpdateUIEvent::SetMode
}{wxupdateuieventsetmode
} or
3393 \helpref{wxUpdateUIEvent::SetUpdateInterval
}{wxupdateuieventsetupdateinterval
} to
3394 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3396 {\it flags
} should be a bitlist of one or more of the following values.
3401 wxUPDATE_UI_NONE =
0x0000, // No particular value
3402 wxUPDATE_UI_RECURSE =
0x0001, // Call the function for descendants
3403 wxUPDATE_UI_FROMIDLE =
0x0002 // Invoked from On(Internal)Idle
3407 If you are calling this function from an OnInternalIdle or OnIdle
3408 function, make sure you pass the wxUPDATE
\_UI\_FROMIDLE flag, since
3409 this tells the window to only update the UI elements that need
3410 to be updated in idle time. Some windows update their elements
3411 only when necessary, for example when a menu is about to be shown.
3412 The following is an example of how to call UpdateWindowUI from
3416 void MyWindow::OnInternalIdle()
3418 if (wxUpdateUIEvent::CanUpdate(this))
3419 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
