2
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.
6
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.
11
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.

33 \wxheading{Window styles}
34
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.
37
38 \twocolwidtha{5cm}%
39 \begin{twocollist}\itemsep=0pt
40 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
41 for this style. }
42 \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows and Mac only.}
43 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
44 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border.}
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
57 Shift-Tab.}
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
60 new window area manually if you use this style. Currently only has an effect for
61 Windows.}
62 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
63 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
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.}

80 \wxheading{Extra window styles}
81
82 The following are extra styles, set using \helpref{wxWindow::SetExtraStyle}{wxwindowsetextrastyle}.
83
84 \twocolwidtha{5cm}%
85 \begin{twocollist}\itemsep=0pt
86 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{By default, Validate/TransferDataTo/FromWindow()
87 only work on direct children of the window (compatible behaviour). Set this flag to make them recursively
88 descend into all subwindows.}
89 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
90 parent window and so on recursively by default. Using this flag for the
91 given window allows to block this propagation at this window, i.e. prevent
92 the events from being propagated further upwards. Dialogs have this
93 flag on by default.}
94 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
95 be used with transient windows as otherwise there is the risk of creating a
96 dialog/frame with this window as a parent which would lead to a crash if the
97 parent is destroyed before the child.}
98 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
99 if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.}
100 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events,
101 even if the mode set by \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} is wxUPDATE\_UI\_PROCESS\_SPECIFIED.}

117 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
118 \param{const wxPoint\& }{pos = wxDefaultPosition},
119 \param{const wxSize\& }{size = wxDefaultSize},
120 \param{long }{style = 0},
121 \param{const wxString\& }{name = wxPanelNameStr}}
122
123 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
124
125 \wxheading{Parameters}
126
127 \docparam{parent}{Pointer to a parent window.}
128
129 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
130
131 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWidgets
132 should generate a default position for the window. If using the wxWindow class directly, supply
133 an actual position.}
134
135 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWidgets
136 should generate a default size for the window. If no suitable size can be found, the
137 window will be sized to 20x20 pixels so that the window is visible but obviously not
138 correctly sized. }
139
140 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
141
142 \docparam{name}{Window name.}
143
144
145 \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
146
147 \func{}{\destruct{wxWindow}}{\void}
148
149 Destructor. Deletes all subwindows, then deletes itself. Instead of using
150 the {\bf delete} operator explicitly, you should normally
151 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
152 can delete a window only when it is safe to do so, in idle time.

160
161 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
162
163 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
164
165 Adds a child window. This is called automatically by window creation
166 functions so should not be required by the application programmer.
167
168 Notice that this function is mostly internal to wxWidgets and shouldn't be
169 called by the user code.
170
171 \wxheading{Parameters}
172
173 \docparam{child}{Child window to add.}
174
175
176 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
177
178 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
179
180 Sets the cached best size value.
181
182
183 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
184
185 \func{virtual void}{CaptureMouse}{\void}
186
187 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
188 release the capture.
189
190 Note that wxWidgets maintains the stack of windows having captured the mouse
191 and when the mouse is released the capture returns to the window which had had
192 captured it previously and it is only really released if there were no previous
193 window. In particular, this means that you must release the mouse as many times
194 as you capture it.

220
221
222 \membersection{wxWindow::Centre}\label{wxwindowcentre}
223
224 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
225
226 Centres the window.
227
228 \wxheading{Parameters}
229
230 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
231 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
232 if you want to center the window on the entire screen and not on its
233 parent window.}
234
235 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
236 (it has no effect).
237
238 \wxheading{Remarks}
239
240 If the window is a top level one (i.e. doesn't have a parent), it will be
241 centered relative to the screen anyhow.

250 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
251
252 Centres the window on its parent. This is a more readable synonym for
253 \helpref{Centre}{wxwindowcentre}.
254
255 \wxheading{Parameters}
256
257 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
258 or {\tt wxBOTH}.}
259
260 \wxheading{Remarks}
261
262 This methods provides for a way to center top level windows over their
263 parents instead of the entire screen. If there is no parent or if the
264 window is not a top level window, then behaviour is the same as
265 \helpref{wxWindow::Centre}{wxwindowcentre}.

273
274 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
275
276 Centres the window on screen. This only works for top level windows -
277 otherwise, the window will still be centered on its parent.
278
279 \wxheading{Parameters}
280
281 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

302 modifying its parameters.}
303
304 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
305
306 Converts to screen coordinates from coordinates relative to this window.
307
308 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
309 a screen coordinate will be passed out.}
310
311 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
312 a screen coordinate will be passed out.}
313
314 \docparam{pt}{The client position for the second form of the function.}
315
316 \pythonnote{In place of a single overloaded method name, wxPython

324
325 \membersection{wxWindow::Close}\label{wxwindowclose}
326
327 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
328
329 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
330 handler usually tries to close the window. It doesn't close the window itself,
331 however.
332
333 \wxheading{Parameters}
334
335 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
336 of this window, {\tt true} if it cannot.}
337
338 \wxheading{Remarks}
339
340 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
341 an opportunity for the window to choose whether to destroy the window.
342 Usually it is only used with the top level windows (wxFrame and wxDialog
343 classes) as the others are not supposed to have any special OnClose() logic.
344
345 The close handler should check whether the window is being deleted forcibly,
346 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
347 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
348
349 {\it Note} that calling Close does not guarantee that the window will be
350 destroyed; but it provides a way to simulate a manual close of a window, which
351 may or may not be implemented by destroying the window. The default
352 implementation of wxDialog::OnCloseWindow does not necessarily delete the
353 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
354 the appropriate button event handler and may do anything at all.
355
356 To guarantee that the window will be destroyed, call
357 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

367
368 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
369
370 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
371
372 Converts a point or size from dialog units to pixels.
373
374 For the x dimension, the dialog units are multiplied by the average character width
375 and then divided by 4.
376
377 For the y dimension, the dialog units are multiplied by the average character height
378 and then divided by 8.
379
380 \wxheading{Remarks}
381
382 Dialog units are used for maintaining a dialog's proportions even if the font changes.
383
384 You can also use these functions programmatically. A convenience macro is defined:
385
386 {\small
387 \begin{verbatim}
388 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

448 Destroys the window safely. Use this function instead of the delete operator, since
449 different window classes can be destroyed differently. Frames and dialogs
450 are not destroyed immediately when this function is called -- they are added
451 to a list of windows to be deleted on idle time, when all the window's events
452 have been processed. This prevents problems with events being sent to non-existent
453 windows.
454

493 Does the window-specific updating after processing the update event.
494 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
495 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
496 act appropriately. For example, to allow frame and dialog title updating, wxWidgets

639
640 Sizes the window so that it fits around its subwindows. This function won't do
641 anything if there are no subwindows and will only really work correctly if the
642 sizers are used for the subwindows layout. Also, if the window has exactly one
643 subwindow it is better (faster and the result is more precise as Fit adds some
644 margin to account for fuzziness of its calculations) to call
645
646 \begin{verbatim}

658 of a window. Mainly useful with scrolled windows to reset scrollbars after
659 sizing changes that do not trigger a size event, and/or scrolled windows without
660 an interior sizer. This function similarly won't do anything if there are no
661 subwindows.
662
663
664 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

666 \func{virtual void}{Freeze}{\void}
667
668 Freezes the window or, in other words, prevents any updates from taking place
669 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
670 be called to reenable window redrawing. Calls to these two functions may be
671 nested.
672
673 This method is useful for visual appearance optimization (for example, it
674 is a good idea to use it before doing many large text insertions in a row into
675 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
676 controls so it is mostly just a hint to wxWidgets and not a mandatory

699
700 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
701 in one thing. GetBestSize should return the minimum untruncated size of the
702 window, while this method will return the largest of BestSize and any user

724 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
725 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
726 application to implement (wxBG\_STYLE\_CUSTOM).
727
728 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
729 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

755 example, for a static control, it will be the minimal size such that the
756 control label is not truncated. For windows containing subwindows (typically
757 \helpref{wxPanel}{wxpanel}), the size returned by this function will be the
758 same as the size the window would have had after calling

805
806 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
807
808 Returns the default font and colours which are used by the control. This is
809 useful if you want to use the same font or colour in your own control as in a
810 standard control -- which is a much better idea than hard coding specific
811 colours or fonts which might look completely out of place on the users
812 system, especially if it uses themes.
813
814 The \arg{variant} parameter is only relevant under Mac currently and is
815 ignore under other platforms. Under Mac, it will change the size of the
816 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
817 for more about this.
818
819 This static method is ``overridden'' in many derived classes and so calling,
820 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
821 return the values appropriate for a button which will be normally different
822 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
823
824 The \texttt{wxVisualAttributes} structure has at least the fields
825 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
826 if it was not possible to determine the default control appearance or,
827 especially for the background colour, if the field doesn't make sense as is
828 the case for \texttt{colBg} for the controls with themed background.

898
899 Currently this is the same as calling
900 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
901
902 One advantage of using this function compared to the static version is that
903 the call is automatically dispatched to the correct class (as usual with
904 virtual functions) and you don't have to specify the class name explicitly.
905
906 The other one is that in the future this function could return different
907 results, for example it might return a different font for an ``Ok'' button
908 than for a generic button if the users GUI is configured to show such buttons
909 in bold font. Of course, the down side is that it is impossible to call this
910 function without actually having an object to apply it to whereas the static
911 version can be used without having to create an object first.

1371 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1372
1373 \func{void}{InheritAttributes}{\void}
1374
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.
1378
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
1388 font might.
1389
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.

1679 %% An example of using this function is in the implementation of escape-character processing for wxDialog,

2168 is called to ensure that the menu items are in the correct state. The menu does
2169 not get deleted by the window.
2170
2171 It is recommended to not explicitly specify coordinates when calling PopupMenu
2172 in response to mouse click, because some of the ports (namely, wxGTK) can do
2173 a better job of positioning the menu in that case.

2187
2188 Pushes this event handler onto the event stack for the window.
2189
2190 \wxheading{Parameters}
2191
2192 \docparam{handler}{Specifies the handler to be pushed.}
2193
2194 \wxheading{Remarks}
2195
2196 An event handler is an object that is capable of processing the events
2197 sent to a window. By default, the window is its own event handler, but
2198 an application may wish to substitute another, for example to allow
2199 central implementation of event-handling for a variety of different
2200 window classes.
2201
2202 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2203 an application to set up a chain of event handlers, where an event not handled by one event handler is
2204 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2205 remove the event handler.

2250 repainted.
2251
2252 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2258
2259 \func{bool}{RegisterHotKey}{\param{int}{ hotkeyId}, \param{int}{ modifiers}, \param{int}{ virtualKeyCode}}
2260
2261 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2262 will receive a hotkey event. It will receive the event even if the application is in the background
2263 and does not have the input focus because the user is working with some other application.

2470
2471 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2472 be called automatically when the window is resized. It is called implicitly by
2473 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2474 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2475 manually or otherwise the window layout won't be correctly updated when its
2476 size changes.
2477
2478 \wxheading{Parameters}

2494 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2495 explanation of the difference between this method and
2496 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.

2498 \wxheading{Parameters}
2499
2500 \docparam{colour}{The colour to be used as the background colour, pass
2501 {\tt wxNullColour} to reset to the default colour.}
2502
2503 \wxheading{Remarks}
2504
2505 The background colour is usually painted by the default\rtfsp
2506 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2507 under Windows and automatically under GTK.
2508
2509 Note that setting the background colour does not cause an immediate refresh, so you
2510 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2511 calling this function.
2512
2513 Using this function will disable attempts to use themes for this
2514 window, if the system supports them. Use with care since usually the
2515 themes represent the appearance chosen by the user to be used for all
2516 applications on the system.

2532 Sets the background style of the window. The background style indicates
2533 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2534 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2535 application to implement (wxBG\_STYLE\_CUSTOM).
2536
2537 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom

2578
2579 This sets the size of the window client area in pixels. Using this function to size a window
2580 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2581 worry about what dimensions the border or title bar have when trying to fit the window

2736
2737 \docparam{handler}{Specifies the handler to be set.}
2738
2739 \wxheading{Remarks}
2740
2741 An event handler is an object that is capable of processing the events
2742 sent to a window. By default, the window is its own event handler, but
2743 an application may wish to substitute another, for example to allow
2744 central implementation of event-handling for a variety of different
2745 window classes.
2746
2747 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2748 this sets up a chain of event handlers, where an event not handled by one event handler is
2749 handed to the next one in the chain.

2769 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
2770 and Validate() methods will recursively descend into all children of the

2772 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2773 events are propagated upwards to the window parent recursively until a handler
2774 for them is found. Using this style allows to prevent them from being
2775 propagated beyond this window. Notice that wxDialog has this style on by
2776 default for the reasons explained in the
2777 \helpref{event processing overview}{eventprocessing}.}
2778 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2779 window from being used as an implicit parent for the dialogs which were
2780 created without a parent. It is useful for the windows which can disappear at
2781 any moment as creating children of such windows results in fatal problems.}
2782 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
2783 caption. When pressed, Windows will go into a context-sensitive help mode and wxWidgets will send
2784 a wxEVT\_HELP event if the user clicked on an application window.
2785 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2786 you should use the style of
2787 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the
2788 frames having this style (the dialogs don't have minimize nor maximize box by

2814 This function is called by wxWidgets keyboard navigation code when the user
2815 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2816 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

2965 \wxheading{Remarks}
2966
2967 Let's say you wish to display 50 lines of text, using the same font.
2968 The window is sized so that you can only see 16 lines at a time.
2969
2970 You would use:
2971
2972 {\small%
2973 \begin{verbatim}
2974 SetScrollbar(wxVERTICAL, 0, 16, 50);
2975 \end{verbatim}
2976 }
2977
2978 Note that with the window at this size, the thumb position can never go
2979 above 50 minus 16, or 34.
2980
2981 You can determine how many lines are currently visible by dividing the current view
2982 size by the character height in pixels.
2983
2984 When defining your own scrollbar behaviour, you will always need to recalculate
2985 the scrollbar settings when the window size changes. You could therefore put your
2986 scrollbar calculations and SetScrollbar
2987 call into a function named AdjustScrollbars, which can be called initially and also
2988 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3011
3012 \wxheading{Remarks}
3013
3014 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3015 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3016 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3017 value has to be adjusted when the window is resized, since the page size will have changed.
3018
3019 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3020 the thumb changes size to reflect the page size relative to the length of the document. When the
3021 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3022 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3023 disappear.
3024
3025 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3026 handling of pages and ranges.

3081
3082 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3083 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3084 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3085 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3086 and usually the scrollbar will be automatically hidden.

3200 \wxheading{Remarks}
3201
3202 If this function is called, the user will not be able to size the window outside the
3203 given bounds.
3204
3205 The resizing increments are only significant under Motif or Xt.

3208 \membersection{wxWindow::SetSizer}\label{wxwindowsetsizer}
3209
3210 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3211
3212 Sets the window to have the given layout sizer. The window
3213 will then own the object, and will take care of its deletion.
3214 If an existing layout constraints object is already owned by the
3215 window, it will be deleted if the deleteOld parameter is true.
3216
3217 Note that this function will also call
3218 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
3219 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
3220
3221 \wxheading{Parameters}
3222
3223 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
3224 the window's sizer. See below.}
3225
3226 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
3227 Pass false if you wish to handle deleting the old sizer yourself.}
3228
3229 \wxheading{Remarks}
3230
3231 SetSizer now enables and disables Layout automatically, but prior to wxWidgets 2.3.3
3232 the following applied:
3233
3234 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3235 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3236 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3237 only the sizer will have effect.

3241
3242 \func{void}{SetSizerAndFit}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3243
3244 The same as \helpref{SetSizer}{wxwindowsetsizer}, except it also sets the size hints
3245 for the window based on the sizer's minimum size.

3263 \membersection{wxWindow::SetThemeEnabled}\label{wxwindowsetthemeenabled}
3264
3265 \func{virtual void}{SetThemeEnabled}{\param{bool }{enable}}
3266
3267 This function tells a window if it should use the system's "theme" code
3268 to draw the windows' background instead if its own background drawing
3269 code. This does not always have any effect since the underlying platform
3270 obviously needs to support the notion of themes in user defined windows.
3271 One such platform is GTK+ where windows can have (very colourful) backgrounds
3272 defined by a user's selected theme.
3273
3274 Dialogs, notebook pages and the status bar have this flag set to true
3275 by default so that the default look and feel is simulated best.

3347
3348 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
3349
3350 Sets the style of the window. Please note that some styles cannot be changed
3351 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
3352 be called after changing the others for the change to take place immediately.

3362
3363 \func{void}{SetWindowVariant}{\param{wxWindowVariant}{variant}}
3364
3365 This function can be called under all platforms but only does anything under
3366 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3367 exist in several sizes which correspond to the elements of wxWindowVariant
3368 enum:
3369 \begin{verbatim}
3370 enum wxWindowVariant
3371 {
3372 wxWINDOW_VARIANT_NORMAL, // Normal size
3373 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3374 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3375 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3376 };
3377 \end{verbatim}
3378
3379 By default the controls use the normal size, of course, but this function can
3380 be used to change this.

3386
3387 Return \true from here to allow the colours of this window to be changed by
3388 \helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3389 forbids inheriting them from the parent window.
3390
3391 The base class version returns \false, but this method is overridden in
3392 \helpref{wxControl}{wxcontrol} where it returns \true.
3393
3394
3395 \membersection{wxWindow::Show}\label{wxwindowshow}
3396
3397 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3398
3399 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3400 for a top level window if you want to bring it to top, although this is not
3401 needed if Show() is called immediately after the frame creation.
3402
3403 \wxheading{Parameters}
3404
3405 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3406
3407 \wxheading{Return value}
3408
3409 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
3410 done because it already was in the requested state.

3421
3422 Reenables window updating after a previous call to

3424 exactly the same number of times as \helpref{Freeze}{wxwindowfreeze}.

3431 Transfers values from child controls to data areas specified by their validators. Returns
3432 {\tt false} if a transfer failed.
3433
3434 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,

3486
3487 \func{virtual void}{Update}{\void}
3488
3489 Calling this method immediately repaints the invalidated area of the window
3490 while this would usually only happen when the flow of control returns to the
3491 event loop. Notice that this function doesn't refresh the window and does
3492 nothing if the window hadn't been already repainted. Use
3493 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3494 window unconditionally.
3495
3496
3497 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3498
3499 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3500
3501 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3502 the window. The particular implementation depends on the window; for
3503 example a wxToolBar will send an update UI event for each toolbar button,
3504 and a wxFrame will send an update UI event for each menubar menu item.
3505 You can call this function from your application to ensure that your
3506 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3507 are concerned). This may be necessary if you have called
3508 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3509 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3510 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3511
3512 {\it flags} should be a bitlist of one or more of the following values.
3513
3514 \begin{verbatim}
3515 enum wxUpdateUI
3516 {
3517 wxUPDATE_UI_NONE = 0x0000, // No particular value
3518 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3519 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3520 };
3521 \end{verbatim}
3522
3523 If you are calling this function from an OnInternalIdle or OnIdle
3524 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3525 this tells the window to only update the UI elements that need
3526 to be updated in idle time. Some windows update their elements
3527 only when necessary, for example when a menu is about to be shown.
3528 The following is an example of how to call UpdateWindowUI from
3529 an idle function.
3530
3531 \begin{verbatim}
3532 void MyWindow::OnInternalIdle()
3533 {
3534 if (wxUpdateUIEvent::CanUpdate(this))
3535 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
