12\section{\class{wxWindow}}\label{wxwindow}
13
14wxWindow is the base class for all windows and represents any visible object on
15screen. All controls, top level windows and so on are windows. Sizers and
16device contexts are not, however, as they don't appear on screen themselves.
17
18Please note that all children of the window will be deleted automatically by
19the destructor before the window itself is deleted which means that you don't
20have to worry about deleting them manually. Please see the \helpref{window
21deletion overview}{windowdeletionoverview} for more information.
22
23Also 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
27are non-virtual because having multiple virtual functions with the same name
28results in a virtual function name hiding at the derived class level (in
29English, this means that the derived class has to override all overloaded
30variants if it overrides any of them). To allow overriding them in the derived
31class, wxWidgets uses a unique protected virtual \texttt{DoGetXXX()} method
32and all \texttt{GetXXX()} ones are forwarded to it, so overriding the former
33changes the behaviour of the latter.

50The following styles can apply to all windows, although they will not always make sense for a particular
51window class or on all platforms.
52
53\twocolwidtha{5cm}%
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
57for this style. }
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
62a 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
66events. 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
69the window wants to get all char/key events for all keys - even for
70keys like TAB or ENTER which are usually used for dialog navigation
71and which wouldn't be generated without this style. If you need to
72use this style in order to get the arrows or etc., but would still like
73to have normal keyboard navigation take place, you should call
74\helpref{Navigate}{wxwindownavigate} in response to the key events for
75Tab and Shift-Tab.}
76\twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
77the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
78and no longer has an effect.}
79\twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical
80scrollbar. Notice that this style cannot be used with native controls
81which don't support scrollbars nor with top-level windows in most ports.}
82\twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal
83scrollbar. The same limitations as for wxVSCROLL apply to this style.}
84\twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
85disable them instead of hiding them when they are not needed (i.e. when the
86size of the window is big enough to not require the scrollbars to navigate it).
87This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
88nothing on the other platforms.}
89\twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
90repainted, then children being painted over them. Windows only.}
91\twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
92a complete redraw of the window whenever it is resized instead of redrawing
93just the part of the window affected by resizing. Note that this was the
94behaviour by default before 2.5.1 release and that if you experience redraw
95problems with code which previously used to work you may want to try this.
96Currently this style applies on GTK+ 2 and Windows only, and full repainting is always
97done on other platforms.}

102\wxheading{Extra window styles}

104The following are extra styles, set using \helpref{wxWindow::SetExtraStyle}{wxwindowsetextrastyle}.
105
106\twocolwidtha{5cm}%
107\begin{twocollist}\itemsep=0pt
108\twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{By default, Validate/TransferDataTo/FromWindow()
109only work on direct children of the window (compatible behaviour). Set this flag to make them recursively
110descend into all subwindows.}
111\twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
112parent window and so on recursively by default. Using this flag for the
113given window allows to block this propagation at this window, i.e. prevent
114the events from being propagated further upwards. Dialogs have this
115flag on by default.}
116\twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
117be used with transient windows as otherwise there is the risk of creating a
118dialog/frame with this window as a parent which would lead to a crash if the
119parent is destroyed before the child.}
120\twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
121if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.}
122\twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events,
123even if the mode set by \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} is wxUPDATE\_UI\_PROCESS\_SPECIFIED.}

135
136\func{}{wxWindow}{\void}
137
138Default constructor.
139
140\func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
141 \param{const wxPoint\& }{pos = wxDefaultPosition},
142 \param{const wxSize\& }{size = wxDefaultSize},
143 \param{long }{style = 0},
144 \param{const wxString\& }{name = wxPanelNameStr}}
145
146Constructs a window, which can be a child of a frame, dialog or any other non-control window.
147
148\wxheading{Parameters}
149
150\docparam{parent}{Pointer to a parent window.}
151
152\docparam{id}{Window identifier. If wxID\_ANY, will automatically create an identifier.}
153
154\docparam{pos}{Window position. wxDefaultPosition indicates that wxWidgets
155should generate a default position for the window. If using the wxWindow class directly, supply
156an actual position.}
157
158\docparam{size}{Window size. wxDefaultSize indicates that wxWidgets
159should generate a default size for the window. If no suitable size can be found, the
160window will be sized to 20x20 pixels so that the window is visible but obviously not
161correctly sized. }
162
163\docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
164
165\docparam{name}{Window name.}
166
167
168\membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
169
170\func{}{\destruct{wxWindow}}{\void}
171
172Destructor. Deletes all subwindows, then deletes itself. Instead of using
173the {\bf delete} operator explicitly, you should normally
174use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
175can delete a window only when it is safe to do so, in idle time.

183
184\membersection{wxWindow::AcceptsFocus}\label{wxwindowacceptsfocus}
185
186\constfunc{bool}{AcceptsFocus}{\void}
187
188This method may be overridden in the derived classes to return \false to
189indicate that this control doesn't accept input at all (i.e. behaves like e.g.
190\helpref{wxStaticText}{wxstatictext}) and so doesn't need focus.
191
192\wxheading{See also}
193
194\helpref{AcceptsFocusFromKeyboard}{wxwindowacceptsfocusfromkeyboard}
195
196
197\membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard}
198
199\constfunc{bool}{AcceptsFocusFromKeyboard}{\void}
200
201This method may be overridden in the derived classes to return \false to
202indicate that while this control can, in principle, have focus if the user
203clicks it with the mouse, it shouldn't be included in the TAB traversal chain
204when using the keyboard.
205
206
207\membersection{wxWindow::AddChild}\label{wxwindowaddchild}
208
209\func{virtual void}{AddChild}{\param{wxWindow* }{child}}
210
211Adds a child window. This is called automatically by window creation
212functions so should not be required by the application programmer.
213
214Notice that this function is mostly internal to wxWidgets and shouldn't be
215called by the user code.
216
217\wxheading{Parameters}
218
219\docparam{child}{Child window to add.}
220
221
222\membersection{wxWindow::AlwaysShowScrollbars}\label{wxwindowalwaysshowscrollbars}
223
224\func{void}{AlwaysShowScrollbars}{\param{bool}{ hflag}, \param{bool}{ vflag}}
225
226Call this function to force one or both scrollbars to be always shown, even if
227the window is big enough to show its entire contents without scrolling.
228
229\newsince{2.9.0}
230
231\wxheading{Parameters}
232
233\docparam{hflag}{Whether the horizontal scroll bar should always be visible.}
234
235\docparam{vflag}{Whether the vertical scroll bar should always be visible.}
236
237\wxheading{Remarks}
238
239This function is currently only implemented under Mac/Carbon.
240
241
242\membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
243
244\constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
245
246Sets the cached best size value.
247
248
249\membersection{wxWindow::CanSetTransparent}\label{wxwindowcansettransparent}
250
251\func{bool}{CanSetTransparent}{\void}
252
253Returns \true if the system supports transparent windows and calling
254\helpref{SetTransparent}{wxwindowsettransparent} may succeed. If this function
255returns \false, transparent windows are definitely not supported by the current
256system.
257
258
259\membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
260
261\func{virtual void}{CaptureMouse}{\void}
262
263Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
264release the capture.
265
266Note that wxWidgets maintains the stack of windows having captured the mouse
267and when the mouse is released the capture returns to the window which had had
268captured it previously and it is only really released if there were no previous
269window. In particular, this means that you must release the mouse as many times
270as you capture it, unless the window receives
271the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
272
273Any application which captures the mouse in the beginning of some operation
274{\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
275and cancel this operation when it receives the event. The event handler must
276not recapture mouse.

287
288A synonym for \helpref{Centre}{wxwindowcentre}.
289
290
291\membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent}
292
293\func{void}{CenterOnParent}{\param{int}{ direction}}

303
304
305\membersection{wxWindow::Centre}\label{wxwindowcentre}
306
307\func{void}{Centre}{\param{int}{ direction = wxBOTH}}
308
309Centres the window.
310
311\wxheading{Parameters}
312
313\docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
314or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
315if you want to center the window on the entire screen and not on its
316parent window.}
317
318The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
319(it has no effect).
320
321\wxheading{Remarks}
322
323If the window is a top level one (i.e. doesn't have a parent), it will be
324centered relative to the screen anyhow.

331\membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
332
333\func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
334
335Centres the window on its parent. This is a more readable synonym for
336\helpref{Centre}{wxwindowcentre}.
337
338\wxheading{Parameters}
339
340\docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
341or {\tt wxBOTH}.}
342
343\wxheading{Remarks}
344
345This methods provides for a way to center top level windows over their
346parents instead of the entire screen. If there is no parent or if the
347window is not a top level window, then behaviour is the same as
348\helpref{wxWindow::Centre}{wxwindowcentre}.

355\membersection{wxWindow::CentreOnScreen}\label{wxwindowcentreonscreen}
356
357\func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
358
359Centres the window on screen. This only works for top level windows -
360otherwise, the window will still be centered on its parent.
361
362\wxheading{Parameters}
363
364\docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

407
408\membersection{wxWindow::Close}\label{wxwindowclose}
409
410\func{bool}{Close}{\param{bool}{ force = {\tt false}}}
411
412This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
413handler usually tries to close the window. It doesn't close the window itself,
414however.
415
416\wxheading{Parameters}
417
418\docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
419of this window, {\tt true} if it cannot.}
420
421\wxheading{Remarks}
422
423Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
424an opportunity for the window to choose whether to destroy the window.
425Usually it is only used with the top level windows (wxFrame and wxDialog
426classes) as the others are not supposed to have any special OnClose() logic.
427
428The close handler should check whether the window is being deleted forcibly,
429using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
430should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
431
432{\it Note} that calling Close does not guarantee that the window will be
433destroyed; but it provides a way to simulate a manual close of a window, which
434may or may not be implemented by destroying the window. The default
435implementation of wxDialog::OnCloseWindow does not necessarily delete the
436dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
437the appropriate button event handler and may do anything at all.
438
439To guarantee that the window will be destroyed, call
440\helpref{wxWindow::Destroy}{wxwindowdestroy} instead

451\func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
452
453\func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
454
455Converts a point or size from dialog units to pixels.
456
457For the x dimension, the dialog units are multiplied by the average character width
458and then divided by 4.
459
460For the y dimension, the dialog units are multiplied by the average character height
461and then divided by 8.
462
463\wxheading{Remarks}
464
465Dialog units are used for maintaining a dialog's proportions even if the font changes.
466
467You can also use these functions programmatically. A convenience macro is defined:
468
469{\small

532different window classes can be destroyed differently. Frames and dialogs
533are not destroyed immediately when this function is called -- they are added
534to a list of windows to be deleted on idle time, when all the window's events
535have been processed. This prevents problems with events being sent to non-existent
536windows.
537
538\wxheading{Return value}
539
540{\tt true} if the window has either been successfully deleted, or it has been added
541to the list of windows pending real deletion.

577This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
578in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
579act appropriately. For example, to allow frame and dialog title updating, wxWidgets

722\func{virtual void}{Fit}{\void}
723
724Sizes the window so that it fits around its subwindows. This function won't do
725anything if there are no subwindows and will only really work correctly if
726sizers are used for the subwindows layout. Also, if the window has exactly one
727subwindow it is better (faster and the result is more precise as Fit adds some
728margin to account for fuzziness of its calculations) to call
729
730\begin{verbatim}

740
741Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
742of a window. Mainly useful with scrolled windows to reset scrollbars after
743sizing changes that do not trigger a size event, and/or scrolled windows without
744an interior sizer. This function similarly won't do anything if there are no
745subwindows.

752Freezes the window or, in other words, prevents any updates from taking place
753on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
754be called to reenable window redrawing. Calls to these two functions may be
755nested.
756
757This method is useful for visual appearance optimization (for example, it
758is a good idea to use it before doing many large text insertions in a row into
759a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
760controls so it is mostly just a hint to wxWidgets and not a mandatory

911
912Returns the default font and colours which are used by the control. This is
913useful if you want to use the same font or colour in your own control as in a
914standard control -- which is a much better idea than hard coding specific
915colours or fonts which might look completely out of place on the users
916system, especially if it uses themes.
917
918The \arg{variant} parameter is only relevant under Mac currently and is
919ignore under other platforms. Under Mac, it will change the size of the
920returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
921for more about this.
922
923This static method is ``overridden'' in many derived classes and so calling,
924for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
925return the values appropriate for a button which will be normally different
926from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
927
928The \texttt{wxVisualAttributes} structure has at least the fields
929\texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
930if it was not possible to determine the default control appearance or,
931especially for the background colour, if the field doesn't make sense as is
932the case for \texttt{colBg} for the controls with themed background.

1006Currently this is the same as calling
1007\helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
1008
1009One advantage of using this function compared to the static version is that
1010the call is automatically dispatched to the correct class (as usual with
1011virtual functions) and you don't have to specify the class name explicitly.
1012
1013The other one is that in the future this function could return different
1014results, for example it might return a different font for an ``Ok'' button
1015than for a generic button if the users GUI is configured to show such buttons
1016in bold font. Of course, the down side is that it is impossible to call this
1017function without actually having an object to apply it to whereas the static
1018version can be used without having to create an object first.

1644the font and the foreground and background colours.
1645
1646By ``intelligently'' the following is meant: by default, all windows use their
1647own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1648if some of the parents attributes are explicitly (that is, using
1649\helpref{SetFont}{wxwindowsetfont} and not
1650\helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1651corresponding attribute hadn't been explicitly set for this window itself,
1652then this window takes the same value as used by the parent. In addition, if
1653the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1654to return \false, the colours will not be changed no matter what and only the
1655font might.
1656
1657This rather complicated logic is necessary in order to accommodate the
1658different usage scenarios. The most common one is when all default attributes
1659are used and in this case, nothing should be inherited as in modern GUIs
1660different controls use different fonts (and colours) than their siblings so
1661they can't inherit the same value from the parent. However it was also deemed
1662desirable to allow to simply change the attributes of all children at once by
1663just changing the font or colour of their common parent, hence in this case we
1664do inherit the parents attributes.

2555An event handler is an object that is capable of processing the events

2557an application may wish to substitute another, for example to allow
2558central implementation of event-handling for a variety of different
2559window classes.
2560
2561\helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2562an application to set up a chain of event handlers, where an event not handled by one event handler is
2563handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

2836
2837Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2838be called automatically when the window is resized. Please note that this only
2839happens for the windows usually used to contain children, namely
2840\helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2841(and the classes deriving from them).
2842
2843This method is called implicitly by
2844\helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2845\helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2846manually or otherwise the window layout won't be correctly updated when its
2847size changes.
2848

2860
2861\func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2862
2863Sets the background colour of the window.
2864
2865Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2866explanation of the difference between this method and
2867\helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2868
2869\wxheading{Parameters}
2870
2871\docparam{colour}{The colour to be used as the background colour, pass
2872 {\tt wxNullColour} to reset to the default colour.}
2873
2874\wxheading{Remarks}
2875
2876The background colour is usually painted by the default\rtfsp
2877\helpref{wxEraseEvent}{wxeraseevent} event handler function
2878under Windows and automatically under GTK.
2879
2880Note that setting the background colour does not cause an immediate refresh, so you
2881may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2882calling this function.
2883
2884Using this function will disable attempts to use themes for this
2885window, if the system supports them. Use with care since usually the
2886themes represent the appearance chosen by the user to be used for all
2887applications on the system.

2918
2919This method is only implemented by ports which have support for
2920native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2921container control code to give the native system a hint when
2922doing TAB traversal. A call to this does not disable or change
2923the effect of programmatically calling

2946This sets the size of the window client area in pixels. Using this function to size a window
2947tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2948worry about what dimensions the border or title bar have when trying to fit the window
2949around panel items, for example.

2951\wxheading{Parameters}
2952

2986explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

3041
3042\docparam{handler}{Specifies the handler to be set.}
3043
3044\wxheading{Remarks}
3045
3046An event handler is an object that is capable of processing the events
3047sent to a window. By default, the window is its own event handler, but
3048an application may wish to substitute another, for example to allow
3049central implementation of event-handling for a variety of different
3050window classes.
3051
3052It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
3053since this sets up a chain of event handlers, where an event not handled by
3054one event handler is handed to the next one in the chain.

3077\twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
3078events are propagated upwards to the window parent recursively until a handler
3079for them is found. Using this style allows to prevent them from being
3080propagated beyond this window. Notice that wxDialog has this style on by
3081default for the reasons explained in the
3082\helpref{event processing overview}{eventprocessing}.}
3083\twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a

3116
3117This function is called by wxWidgets keyboard navigation code when the user
3118gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
3119By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

3129use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
3130see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
3131explanations.
3132
3133Please notice that the given font is \emph{not} automatically used for
3134\helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to

3365
3366Let's say you wish to display 50 lines of text, using the same font.
3367The window is sized so that you can only see 16 lines at a time.
3368
3369You would use:
3370
3371{\small%
3372\begin{verbatim}
3373 SetScrollbar(wxVERTICAL, 0, 16, 50);
3374\end{verbatim}
3375}
3376
3377Note that with the window at this size, the thumb position can never go
3378above 50 minus 16, or 34.
3379
3380You can determine how many lines are currently visible by dividing the current view
3381size by the character height in pixels.
3382
3383When defining your own scrollbar behaviour, you will always need to recalculate
3384the scrollbar settings when the window size changes. You could therefore put your
3385scrollbar calculations and SetScrollbar
3386call into a function named AdjustScrollbars, which can be called initially and also
3387from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3411
3412\wxheading{Remarks}
3413
3414The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3415click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3416page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3417value has to be adjusted when the window is resized, since the page size will have changed.
3418
3419In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3420the thumb changes size to reflect the page size relative to the length of the document. When the
3421document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3422will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3423disappear.
3424
3425Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3426handling of pages and ranges.

3481
3482The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3483object length of the scrollbar. If you are implementing a scrolling window, for example, you
3484would adjust the scroll range when the window is resized, by subtracting the window view size from the
3485total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3486and usually the scrollbar will be automatically hidden.

3629to draw the windows' background instead if its own background drawing
3630code. This does not always have any effect since the underlying platform

3632One such platform is GTK+ where windows can have (very colourful) backgrounds
3633defined by a user's selected theme.

3740
3741This function can be called under all platforms but only does anything under
3742Mac OS X 10.3+ currently. Under this system, each of the standard control can
3743exist in several sizes which correspond to the elements of wxWindowVariant
3744enum:
3745\begin{verbatim}
3746enum wxWindowVariant
3747{
3748 wxWINDOW_VARIANT_NORMAL, // Normal size
3749 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3750 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3751 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3752};
3753\end{verbatim}
3754
3755By default the controls use the normal size, of course, but this function can
3756be used to change this.

3764\helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3765forbids inheriting them from the parent window.

3771\membersection{wxWindow::Show}\label{wxwindowshow}
3772
3773\func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3774
3775Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3776for a top level window if you want to bring it to top, although this is not
3777needed if Show() is called immediately after the frame creation.

3780
3781\docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3782
3783\wxheading{Return value}

3796
3797\func{virtual bool}{ShowWithEffect}{\param{wxShowEffect }{effect}, \param{unsigned }{timeout = $0$}, \param{wxDirection }{dir = wxBOTTOM}}
3798
3799This function shows a window, like \helpref{Show()}{wxwindowshow}, but using a
3800special visual effect if possible.
3801
3802Possible values for \arg{effect} are:
3803\begin{twocollist}\itemsep=0pt
3804\twocolitem{wxSHOW\_EFFECT\_ROLL}{Roll window effect}
3805\twocolitem{wxSHOW\_EFFECT\_SLIDE}{Sliding window effect}
3806\twocolitem{wxSHOW\_EFFECT\_BLEND}{Fade in or out effect}
3807\twocolitem{wxSHOW\_EFFECT\_EXPAND}{Expanding or collapsing effect}
3808\end{twocollist}
3809
3810For the roll and slide effects the \arg{dir} parameter specifies the animation
3811direction: it can be one of \texttt{wxTOP}, \texttt{wxBOTTOM}, \texttt{wxLEFT}
3812or \texttt{wxRIGHT}. For the other effects, this parameter is unused.
3813
3814The \arg{timeout} parameter specifies the time of the animation, in
3815milliseconds. If the default value of $0$ is used, the default animation time
3816for the current platform is used.
3817
3818Currently this function is only implemented in wxMSW and does the same thing as
3819Show() in the other ports.

3922
3923\func{virtual void}{Update}{\void}
3924
3925Calling this method immediately repaints the invalidated area of the window and
3926all of its children recursively while this would usually only happen when the
3927flow of control returns to the event loop.
3928Notice that this function doesn't invalidate any area of the window so
3929nothing happens if nothing has been invalidated (i.e. marked as requiring
3930a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3931immediately redraw the window unconditionally.
3932
3933
3934\membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3935
3936\func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3937
3938This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3939the window. The particular implementation depends on the window; for
3940example a wxToolBar will send an update UI event for each toolbar button,
3941and a wxFrame will send an update UI event for each menubar menu item.
3942You can call this function from your application to ensure that your
3943UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3944are concerned). This may be necessary if you have called
3945\helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3946\helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3947limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3948
3949{\it flags} should be a bitlist of one or more of the following values.
3950
3951\begin{verbatim}
3952enum wxUpdateUI
3953{
3954 wxUPDATE_UI_NONE = 0x0000, // No particular value
3955 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3956 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3957};
3958\end{verbatim}
3959
3960If you are calling this function from an OnInternalIdle or OnIdle
3961function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3962this tells the window to only update the UI elements that need
3963to be updated in idle time. Some windows update their elements
3964only when necessary, for example when a menu is about to be shown.
3965The following is an example of how to call UpdateWindowUI from
3966an idle function.
3967
3968\begin{verbatim}
3969void MyWindow::OnInternalIdle()
3970{
3971 if (wxUpdateUIEvent::CanUpdate(this))
3972 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
