12 \section{\class{wxWindow}}\label{wxwindow}
13
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.
17
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.
22
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.

44 \wxheading{Window styles}
45
46 The following styles can apply to all windows, although they will not always make sense for a particular
47 window class or on all platforms.
48
49 \twocolwidtha{5cm}%
50 \begin{twocollist}\itemsep=0pt
51 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
52 for this style. }
53 \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows and Mac only.}
54 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
55 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border.}
56 \twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control. Windows only. }
57 \twocolitem{\windowstyle{wxNO\_BORDER}}{Displays no border, overriding the default border style for the window.}
58 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
59 events. Windows only.}
60 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
61 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
62 the window wants to get all char/key events for all keys - even for
63 keys like TAB or ENTER which are usually used for dialog navigation
64 and which wouldn't be generated without this style. If you need to
65 use this style in order to get the arrows or etc., but would still like to have
66 normal keyboard navigation take place, you should create and send a
67 wxNavigationKeyEvent in response to the key events for Tab and
68 Shift-Tab.}
69 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
70 the window completely when its size is changed - you will have to repaint the
71 new window area manually if you use this style. Currently only has an effect for
72 Windows.}
73 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
74 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
75 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
76 disable them instead of hiding them when they are not needed (i.e. when the
77 size of the window is big enough to not require the scrollbars to navigate it).
78 This style is currently only implemented for wxMSW and wxUniversal and does
79 nothing on the other platforms.}
80 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
81 repainted, then children being painted over them. Windows only.}
82 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
83 a complete redraw of the window whenever it is resized instead of redrawing
84 just the part of the window affected by resizing. Note that this was the
85 behaviour by default before 2.5.1 release and that if you experience redraw
86 problems with the code which previously used to work you may want to try this.}

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

122 \membersection{wxWindow::wxWindow}\label{wxwindowctor}
123
124 \func{}{wxWindow}{\void}
125
126 Default constructor.
127
128 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
129 \param{const wxPoint\& }{pos = wxDefaultPosition},
130 \param{const wxSize\& }{size = wxDefaultSize},
131 \param{long }{style = 0},
132 \param{const wxString\& }{name = wxPanelNameStr}}
133
134 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
135
136 \wxheading{Parameters}
137
138 \docparam{parent}{Pointer to a parent window.}
139
140 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
141
142 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWidgets
143 should generate a default position for the window. If using the wxWindow class directly, supply
144 an actual position.}
145
146 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWidgets
147 should generate a default size for the window. If no suitable size can be found, the
148 window will be sized to 20x20 pixels so that the window is visible but obviously not
149 correctly sized. }
150
151 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
152
153 \docparam{name}{Window name.}
154
155
156 \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
157
158 \func{}{\destruct{wxWindow}}{\void}
159
160 Destructor. Deletes all subwindows, then deletes itself. Instead of using
161 the {\bf delete} operator explicitly, you should normally
162 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
163 can delete a window only when it is safe to do so, in idle time.

170
171
172 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
173
174 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
175
176 Adds a child window. This is called automatically by window creation
177 functions so should not be required by the application programmer.
178
179 Notice that this function is mostly internal to wxWidgets and shouldn't be
180 called by the user code.
181
182 \wxheading{Parameters}
183
184 \docparam{child}{Child window to add.}
185
186
187 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
188
189 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
190
191 Sets the cached best size value.
192
193
194 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
195
196 \func{virtual void}{CaptureMouse}{\void}
197
198 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
199 release the capture.
200
201 Note that wxWidgets maintains the stack of windows having captured the mouse
202 and when the mouse is released the capture returns to the window which had had
203 captured it previously and it is only really released if there were no previous
204 window. In particular, this means that you must release the mouse as many times
205 as you capture it.

215
216 A synonym for \helpref{Centre}{wxwindowcentre}.
217
218
219 \membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent}

224
225
226 \membersection{wxWindow::CenterOnScreen}\label{wxwindowcenteronscreen}
227
228 \func{void}{CenterOnScreen}{\param{int}{ direction}}
229
230 A synonym for \helpref{CentreOnScreen}{wxwindowcentreonscreen}.
231
232
233 \membersection{wxWindow::Centre}\label{wxwindowcentre}
234
235 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
236
237 Centres the window.
238
239 \wxheading{Parameters}
240
241 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
242 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
243 if you want to center the window on the entire screen and not on its
244 parent window.}
245
246 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
247 (it has no effect).
248
249 \wxheading{Remarks}
250
251 If the window is a top level one (i.e. doesn't have a parent), it will be
252 centered relative to the screen anyhow.

259 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
260
261 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
262
263 Centres the window on its parent. This is a more readable synonym for
264 \helpref{Centre}{wxwindowcentre}.
265
266 \wxheading{Parameters}
267
268 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
269 or {\tt wxBOTH}.}
270
271 \wxheading{Remarks}
272
273 This methods provides for a way to center top level windows over their
274 parents instead of the entire screen. If there is no parent or if the
275 window is not a top level window, then behaviour is the same as
276 \helpref{wxWindow::Centre}{wxwindowcentre}.

284
285 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
286
287 Centres the window on screen. This only works for top level windows -
288 otherwise, the window will still be centered on its parent.
289
290 \wxheading{Parameters}
291
292 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

305 cause an erase background event to be generated.
306
307
308 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}

313 modifying its parameters.}
314
315 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
316
317 Converts to screen coordinates from coordinates relative to this window.
318
319 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
320 a screen coordinate will be passed out.}
321
322 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
323 a screen coordinate will be passed out.}
324
325 \docparam{pt}{The client position for the second form of the function.}
326
327 \pythonnote{In place of a single overloaded method name, wxPython
328 implements the following methods:\par

335
336 \membersection{wxWindow::Close}\label{wxwindowclose}
337
338 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
339
340 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
341 handler usually tries to close the window. It doesn't close the window itself,
342 however.
343
344 \wxheading{Parameters}
345
346 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
347 of this window, {\tt true} if it cannot.}
348
349 \wxheading{Remarks}
350
351 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
352 an opportunity for the window to choose whether to destroy the window.
353 Usually it is only used with the top level windows (wxFrame and wxDialog
354 classes) as the others are not supposed to have any special OnClose() logic.
355
356 The close handler should check whether the window is being deleted forcibly,
357 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
358 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
359
360 {\it Note} that calling Close does not guarantee that the window will be
361 destroyed; but it provides a way to simulate a manual close of a window, which
362 may or may not be implemented by destroying the window. The default
363 implementation of wxDialog::OnCloseWindow does not necessarily delete the
364 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
365 the appropriate button event handler and may do anything at all.
366
367 To guarantee that the window will be destroyed, call
368 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

378
379 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
380
381 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
382
383 Converts a point or size from dialog units to pixels.
384
385 For the x dimension, the dialog units are multiplied by the average character width
386 and then divided by 4.
387
388 For the y dimension, the dialog units are multiplied by the average character height
389 and then divided by 8.
390
391 \wxheading{Remarks}
392
393 Dialog units are used for maintaining a dialog's proportions even if the font changes.
394
395 You can also use these functions programmatically. A convenience macro is defined:
396
397 {\small
398 \begin{verbatim}
399 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

458
459 Destroys the window safely. Use this function instead of the delete operator, since
460 different window classes can be destroyed differently. Frames and dialogs
461 are not destroyed immediately when this function is called -- they are added
462 to a list of windows to be deleted on idle time, when all the window's events
463 have been processed. This prevents problems with events being sent to non-existent
464 windows.
465
466 \wxheading{Return value}

501
502 \func{virtual void}{DoUpdateWindowUI}{\param{wxUpdateUIEvent\&}{ event}}
503
504 Does the window-specific updating after processing the update event.
505 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
506 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
507 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
508 implements this function as follows:

649
650 \func{virtual void}{Fit}{\void}
651
652 Sizes the window so that it fits around its subwindows. This function won't do
653 anything if there are no subwindows and will only really work correctly if the
654 sizers are used for the subwindows layout. Also, if the window has exactly one
655 subwindow it is better (faster and the result is more precise as Fit adds some
656 margin to account for fuzziness of its calculations) to call
657
658 \begin{verbatim}
659 window->SetClientSize(child->GetSize());

664
665 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}
666
667 \func{virtual void}{FitInside}{\void}
668
669 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
670 of a window. Mainly useful with scrolled windows to reset scrollbars after
671 sizing changes that do not trigger a size event, and/or scrolled windows without
672 an interior sizer. This function similarly won't do anything if there are no
673 subwindows.
674
675
676 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}
677
678 \func{virtual void}{Freeze}{\void}
679
680 Freezes the window or, in other words, prevents any updates from taking place
681 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
682 be called to reenable window redrawing. Calls to these two functions may be
683 nested.
684
685 This method is useful for visual appearance optimization (for example, it
686 is a good idea to use it before doing many large text insertions in a row into
687 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
688 controls so it is mostly just a hint to wxWidgets and not a mandatory

710 \constfunc{wxSize}{GetAdjustedBestSize}{\void}
711
712 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
713 in one thing. GetBestSize should return the minimum untruncated size of the
714 window, while this method will return the largest of BestSize and any user
715 specified minimum size. ie. it is the minimum size the window should currently
716 be drawn at, not the minimal size it can possibly tolerate.

736 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
737 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
738 application to implement (wxBG\_STYLE\_CUSTOM).
739
740 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
741 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

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

817
818 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
819
820 Returns the default font and colours which are used by the control. This is
821 useful if you want to use the same font or colour in your own control as in a
822 standard control -- which is a much better idea than hard coding specific
823 colours or fonts which might look completely out of place on the users
824 system, especially if it uses themes.
825
826 The \arg{variant} parameter is only relevant under Mac currently and is
827 ignore under other platforms. Under Mac, it will change the size of the
828 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
829 for more about this.
830
831 This static method is ``overridden'' in many derived classes and so calling,
832 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
833 return the values appropriate for a button which will be normally different
834 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
835
836 The \texttt{wxVisualAttributes} structure has at least the fields
837 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
838 if it was not possible to determine the default control appearance or,
839 especially for the background colour, if the field doesn't make sense as is
840 the case for \texttt{colBg} for the controls with themed background.

908
909 \constfunc{virtual wxVisualAttributes}{GetDefaultAttributes}{\void}
910
911 Currently this is the same as calling
912 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
913
914 One advantage of using this function compared to the static version is that
915 the call is automatically dispatched to the correct class (as usual with
916 virtual functions) and you don't have to specify the class name explicitly.
917
918 The other one is that in the future this function could return different
919 results, for example it might return a different font for an ``Ok'' button
920 than for a generic button if the users GUI is configured to show such buttons
921 in bold font. Of course, the down side is that it is impossible to call this
922 function without actually having an object to apply it to whereas the static
923 version can be used without having to create an object first.

1370 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1371
1372 \func{void}{InheritAttributes}{\void}
1373
1374 This function is (or should be, in case of custom controls) called during
1375 window creation to intelligently set up the window visual attributes, that is
1376 the font and the foreground and background colours.
1377
1378 By ``intelligently'' the following is meant: by default, all windows use their
1379 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1380 if some of the parents attributes are explicitly (that is, using
1381 \helpref{SetFont}{wxwindowsetfont} and not
1382 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1383 corresponding attribute hadn't been explicitly set for this window itself,
1384 then this window takes the same value as used by the parent. In addition, if
1385 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1386 to return \false, the colours will not be changed no matter what and only the
1387 font might.
1388
1389 This rather complicated logic is necessary in order to accommodate the
1390 different usage scenarios. The most common one is when all default attributes
1391 are used and in this case, nothing should be inherited as in modern GUIs
1392 different controls use different fonts (and colours) than their siblings so
1393 they can't inherit the same value from the parent. However it was also deemed
1394 desirable to allow to simply change the attributes of all children at once by
1395 just changing the font or colour of their common parent, hence in this case we
1396 do inherit the parents attributes.

1678 %% An example of using this function is in the implementation of escape-character processing for wxDialog,

2167 is called to ensure that the menu items are in the correct state. The menu does
2168 not get deleted by the window.
2169
2170 It is recommended to not explicitly specify coordinates when calling PopupMenu
2171 in response to mouse click, because some of the ports (namely, wxGTK) can do
2172 a better job of positioning the menu in that case.

2186
2187 Pushes this event handler onto the event stack for the window.
2188
2189 \wxheading{Parameters}
2190
2191 \docparam{handler}{Specifies the handler to be pushed.}
2192
2193 \wxheading{Remarks}
2194
2195 An event handler is an object that is capable of processing the events
2196 sent to a window. By default, the window is its own event handler, but
2197 an application may wish to substitute another, for example to allow
2198 central implementation of event-handling for a variety of different
2199 window classes.
2200
2201 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2202 an application to set up a chain of event handlers, where an event not handled by one event handler is
2203 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2204 remove the event handler.

2249 repainted.
2250
2251 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

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

2476
2477 \wxheading{Parameters}

2497 \wxheading{Parameters}
2498
2499 \docparam{colour}{The colour to be used as the background colour, pass
2500 {\tt wxNullColour} to reset to the default colour.}
2501
2502 \wxheading{Remarks}
2503
2504 The background colour is usually painted by the default\rtfsp
2505 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2506 under Windows and automatically under GTK.
2507
2508 Note that setting the background colour does not cause an immediate refresh, so you
2509 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2510 calling this function.
2511
2512 Using this function will disable attempts to use themes for this
2513 window, if the system supports them. Use with care since usually the
2514 themes represent the appearance chosen by the user to be used for all
2515 applications on the system.

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

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

2735
2736 \docparam{handler}{Specifies the handler to be set.}
2737
2738 \wxheading{Remarks}
2739
2740 An event handler is an object that is capable of processing the events
2741 sent to a window. By default, the window is its own event handler, but
2742 an application may wish to substitute another, for example to allow
2743 central implementation of event-handling for a variety of different
2744 window classes.
2745
2746 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2747 this sets up a chain of event handlers, where an event not handled by one event handler is
2748 handed to the next one in the chain.

2766 \twocolwidtha{5cm}%
2767 \begin{twocollist}\itemsep=0pt
2768 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
2769 and Validate() methods will recursively descend into all children of the
2770 window if it has this style flag set.}
2771 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2772 events are propagated upwards to the window parent recursively until a handler
2773 for them is found. Using this style allows to prevent them from being
2774 propagated beyond this window. Notice that wxDialog has this style on by
2775 default for the reasons explained in the
2776 \helpref{event processing overview}{eventprocessing}.}
2777 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2778 window from being used as an implicit parent for the dialogs which were
2779 created without a parent. It is useful for the windows which can disappear at
2780 any moment as creating children of such windows results in fatal problems.}
2781 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
2782 caption. When pressed, Windows will go into a context-sensitive help mode and wxWidgets will send
2783 a wxEVT\_HELP event if the user clicked on an application window.
2784 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2785 you should use the style of
2786 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the
2787 frames having this style (the dialogs don't have minimize nor maximize box by

2813 This function is called by wxWidgets keyboard navigation code when the user
2814 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2815 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

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

3010
3011 \wxheading{Remarks}
3012
3013 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3014 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3015 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3016 value has to be adjusted when the window is resized, since the page size will have changed.
3017
3018 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3019 the thumb changes size to reflect the page size relative to the length of the document. When the
3020 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3021 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3022 disappear.
3023
3024 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3025 handling of pages and ranges.

3080
3081 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3082 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3083 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3084 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3085 and usually the scrollbar will be automatically hidden.

3197 \docparam{incSize}{Increment size (Motif/Xt only).}
3198
3199 \wxheading{Remarks}
3200
3201 If this function is called, the user will not be able to size the window outside the
3202 given bounds.
3203
3204 The resizing increments are only significant under Motif or Xt.

3207 \membersection{wxWindow::SetSizer}\label{wxwindowsetsizer}
3208
3209 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3210
3211 Sets the window to have the given layout sizer. The window
3212 will then own the object, and will take care of its deletion.
3213 If an existing layout constraints object is already owned by the
3214 window, it will be deleted if the deleteOld parameter is true.
3215
3216 Note that this function will also call
3217 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
3218 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
3219
3220 \wxheading{Parameters}
3221
3222 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
3223 the window's sizer. See below.}
3224
3225 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
3226 Pass false if you wish to handle deleting the old sizer yourself.}
3227
3228 \wxheading{Remarks}
3229
3230 SetSizer now enables and disables Layout automatically, but prior to wxWidgets 2.3.3
3231 the following applied:
3232
3233 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3234 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3235 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3236 only the sizer will have effect.

3240
3241 \func{void}{SetSizerAndFit}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3242
3243 The same as \helpref{SetSizer}{wxwindowsetsizer}, except it also sets the size hints
3244 for the window based on the sizer's minimum size.

3246
3247 \membersection{wxWindow::SetTitle}\label{wxwindowsettitle}
3248
3249 \func{virtual void}{SetTitle}{\param{const wxString\& }{title}}

3262 \membersection{wxWindow::SetThemeEnabled}\label{wxwindowsetthemeenabled}
3263
3264 \func{virtual void}{SetThemeEnabled}{\param{bool }{enable}}
3265
3266 This function tells a window if it should use the system's "theme" code
3267 to draw the windows' background instead if its own background drawing
3268 code. This does not always have any effect since the underlying platform
3269 obviously needs to support the notion of themes in user defined windows.
3270 One such platform is GTK+ where windows can have (very colourful) backgrounds
3271 defined by a user's selected theme.
3272
3273 Dialogs, notebook pages and the status bar have this flag set to true
3274 by default so that the default look and feel is simulated best.

3345 \membersection{wxWindow::SetWindowStyleFlag}\label{wxwindowsetwindowstyleflag}
3346
3347 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
3348
3349 Sets the style of the window. Please note that some styles cannot be changed
3350 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
3351 be called after changing the others for the change to take place immediately.

3361
3362 \func{void}{SetWindowVariant}{\param{wxWindowVariant}{variant}}
3363
3364 This function can be called under all platforms but only does anything under
3365 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3366 exist in several sizes which correspond to the elements of wxWindowVariant
3367 enum:
3368 \begin{verbatim}
3369 enum wxWindowVariant
3370 {
3371 wxWINDOW_VARIANT_NORMAL, // Normal size
3372 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3373 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3374 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3375 };
3376 \end{verbatim}
3377
3378 By default the controls use the normal size, of course, but this function can
3379 be used to change this.

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

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);
