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}}{On Windows, this style used to disable repainting
70 the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
71 and no longer has an effect.}
72 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
73 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
74 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
75 disable them instead of hiding them when they are not needed (i.e. when the
76 size of the window is big enough to not require the scrollbars to navigate it).
77 This style is currently only implemented for wxMSW and wxUniversal and does
78 nothing on the other platforms.}
79 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
80 repainted, then children being painted over them. Windows only.}
81 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
82 a complete redraw of the window whenever it is resized instead of redrawing
83 just the part of the window affected by resizing. Note that this was the
84 behaviour by default before 2.5.1 release and that if you experience redraw
85 problems with code which previously used to work you may want to try this.
86 Currently this style applies on GTK+ 2 and Windows only, and full repainting is always
87 done on other platforms.}

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

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

171
172
173 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
174
175 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
176
177 Adds a child window. This is called automatically by window creation
178 functions so should not be required by the application programmer.
179
180 Notice that this function is mostly internal to wxWidgets and shouldn't be
181 called by the user code.
182
183 \wxheading{Parameters}
184
185 \docparam{child}{Child window to add.}
186
187
188 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
189
190 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
191
192 Sets the cached best size value.
193
194
195 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
196
197 \func{virtual void}{CaptureMouse}{\void}
198
199 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
200 release the capture.
201
202 Note that wxWidgets maintains the stack of windows having captured the mouse
203 and when the mouse is released the capture returns to the window which had had
204 captured it previously and it is only really released if there were no previous
205 window. In particular, this means that you must release the mouse as many times
206 as you capture it.
207

214
215 \func{void}{Center}{\param{int}{ direction}}
216
217 A synonym for \helpref{Centre}{wxwindowcentre}.
218
219
220 \membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent}

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

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

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

306 cause an erase background event to be generated.
307
308
309 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}
310
311 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}

313 \perlnote{In wxPerl this method returns a 2-element list instead of
314 modifying its parameters.}
315
316 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
317
318 Converts to screen coordinates from coordinates relative to this window.
319
320 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
321 a screen coordinate will be passed out.}
322
323 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
324 a screen coordinate will be passed out.}
325
326 \docparam{pt}{The client position for the second form of the function.}
327
328 \pythonnote{In place of a single overloaded method name, wxPython
329 implements the following methods:\par
330 \indented{2cm}{\begin{twocollist}

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

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

457
458 \func{virtual bool}{Destroy}{\void}
459
460 Destroys the window safely. Use this function instead of the delete operator, since
461 different window classes can be destroyed differently. Frames and dialogs
462 are not destroyed immediately when this function is called -- they are added
463 to a list of windows to be deleted on idle time, when all the window's events
464 have been processed. This prevents problems with events being sent to non-existent
465 windows.
466
467 \wxheading{Return value}

496 Gets the size which best suits the window: for a control, it would be
497 the minimal size which doesn't truncate the control, for a panel - the
498 same size as it would have after a call to \helpref{Fit()}{wxwindowfit}.

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

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

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

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

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

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

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

909
910 \constfunc{virtual wxVisualAttributes}{GetDefaultAttributes}{\void}
911
912 Currently this is the same as calling
913 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
914
915 One advantage of using this function compared to the static version is that
916 the call is automatically dispatched to the correct class (as usual with
917 virtual functions) and you don't have to specify the class name explicitly.
918
919 The other one is that in the future this function could return different
920 results, for example it might return a different font for an ``Ok'' button
921 than for a generic button if the users GUI is configured to show such buttons
922 in bold font. Of course, the down side is that it is impossible to call this
923 function without actually having an object to apply it to whereas the static
924 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.

1678 %%
1679 %% An example of using this function is in the implementation of escape-character processing for wxDialog,

2167 Just before the menu is popped up, \helpref{wxMenu::UpdateUI}{wxmenuupdateui}
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.

2225
2226 \func{virtual void}{Refresh}{\param{bool}{ eraseBackground = {\tt true}}, \param{const wxRect* }{rect = NULL}}
2227
2228 Causes this window, and all of its children recursively (except under wxGTK1
2229 where this is not implemented), to be repainted. Note that repainting doesn't
2230 happen immediately but only during the next event loop iteration, if you need
2231 to update the window immediately you should use \helpref{Update}{wxwindowupdate}
2232 instead.

2250
2251 Redraws the contents of the given rectangle: only the area inside it will be
2252 repainted.
2253
2254 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax
2255 as it can be called with a temporary wxRect object as argument like this
2256 \texttt{RefreshRect(wxRect(x, y, w, h))}.

2260
2261 \func{bool}{RegisterHotKey}{\param{int}{ hotkeyId}, \param{int}{ modifiers}, \param{int}{ virtualKeyCode}}
2262
2263 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2264 will receive a hotkey event. It will receive the event even if the application is in the background
2265 and does not have the input focus because the user is working with some other application.

2267 \wxheading{Parameters}
2268
2269 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If

2284
2285 Use EVT\_HOTKEY(hotkeyId, fnc) in the event table to capture the event.

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

2480
2481 \wxheading{Parameters}

2501 \wxheading{Parameters}
2502
2503 \docparam{colour}{The colour to be used as the background colour, pass
2504 {\tt wxNullColour} to reset to the default colour.}
2505
2506 \wxheading{Remarks}
2507
2508 The background colour is usually painted by the default\rtfsp
2509 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2510 under Windows and automatically under GTK.
2511
2512 Note that setting the background colour does not cause an immediate refresh, so you
2513 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2514 calling this function.
2515
2516 Using this function will disable attempts to use themes for this
2517 window, if the system supports them. Use with care since usually the
2518 themes represent the appearance chosen by the user to be used for all
2519 applications on the system.

2536 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2537 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2538 application to implement (wxBG\_STYLE\_CUSTOM).
2539
2540 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom

2581
2582 This sets the size of the window client area in pixels. Using this function to size a window
2583 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2584 worry about what dimensions the border or title bar have when trying to fit the window

2739
2740 \docparam{handler}{Specifies the handler to be set.}
2741
2742 \wxheading{Remarks}
2743
2744 An event handler is an object that is capable of processing the events
2745 sent to a window. By default, the window is its own event handler, but
2746 an application may wish to substitute another, for example to allow
2747 central implementation of event-handling for a variety of different
2748 window classes.
2749
2750 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2751 this sets up a chain of event handlers, where an event not handled by one event handler is
2752 handed to the next one in the chain.

2772 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
2773 and Validate() methods will recursively descend into all children of the

2775 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2776 events are propagated upwards to the window parent recursively until a handler
2777 for them is found. Using this style allows to prevent them from being
2778 propagated beyond this window. Notice that wxDialog has this style on by
2779 default for the reasons explained in the
2780 \helpref{event processing overview}{eventprocessing}.}
2781 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2782 window from being used as an implicit parent for the dialogs which were
2783 created without a parent. It is useful for the windows which can disappear at
2784 any moment as creating children of such windows results in fatal problems.}
2785 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
2786 caption. When pressed, Windows will go into a context-sensitive help mode and wxWidgets will send
2787 a wxEVT\_HELP event if the user clicked on an application window.
2788 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2789 you should use the style of
2790 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the
2791 frames having this style (the dialogs don't have minimize nor maximize box by

2817 This function is called by wxWidgets keyboard navigation code when the user
2818 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2819 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

2969
2970 Let's say you wish to display 50 lines of text, using the same font.
2971 The window is sized so that you can only see 16 lines at a time.
2972
2973 You would use:
2974
2975 {\small%
2976 \begin{verbatim}
2977 SetScrollbar(wxVERTICAL, 0, 16, 50);
2978 \end{verbatim}
2979 }
2980
2981 Note that with the window at this size, the thumb position can never go
2982 above 50 minus 16, or 34.
2983
2984 You can determine how many lines are currently visible by dividing the current view
2985 size by the character height in pixels.
2986
2987 When defining your own scrollbar behaviour, you will always need to recalculate
2988 the scrollbar settings when the window size changes. You could therefore put your
2989 scrollbar calculations and SetScrollbar
2990 call into a function named AdjustScrollbars, which can be called initially and also
2991 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3014
3015 \wxheading{Remarks}
3016
3017 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3018 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3019 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3020 value has to be adjusted when the window is resized, since the page size will have changed.
3021
3022 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3023 the thumb changes size to reflect the page size relative to the length of the document. When the
3024 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3025 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3026 disappear.
3027
3028 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3029 handling of pages and ranges.

3084
3085 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3086 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3087 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3088 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3089 and usually the scrollbar will be automatically hidden.

3203 \wxheading{Remarks}
3204
3205 If this function is called, the user will not be able to size the window outside the
3206 given bounds.
3207
3208 The resizing increments are only significant under Motif or Xt.

3211 \membersection{wxWindow::SetSizer}\label{wxwindowsetsizer}
3212
3213 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3214
3215 Sets the window to have the given layout sizer. The window
3216 will then own the object, and will take care of its deletion.
3217 If an existing layout constraints object is already owned by the
3218 window, it will be deleted if the deleteOld parameter is true.
3219
3220 Note that this function will also call
3221 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
3222 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
3223
3224 \wxheading{Parameters}
3225
3226 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
3227 the window's sizer. See below.}
3228
3229 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
3230 Pass false if you wish to handle deleting the old sizer yourself.}
3231
3232 \wxheading{Remarks}
3233
3234 SetSizer now enables and disables Layout automatically, but prior to wxWidgets 2.3.3
3235 the following applied:
3236
3237 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3238 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3239 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3240 only the sizer will have effect.

3244
3245 \func{void}{SetSizerAndFit}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3246
3247 The same as \helpref{SetSizer}{wxwindowsetsizer}, except it also sets the size hints
3248 for the window based on the sizer's minimum size.

3251 \membersection{wxWindow::SetTitle}\label{wxwindowsettitle}

3266 \membersection{wxWindow::SetThemeEnabled}\label{wxwindowsetthemeenabled}
3267
3268 \func{virtual void}{SetThemeEnabled}{\param{bool }{enable}}
3269
3270 This function tells a window if it should use the system's "theme" code
3271 to draw the windows' background instead if its own background drawing
3272 code. This does not always have any effect since the underlying platform
3273 obviously needs to support the notion of themes in user defined windows.
3274 One such platform is GTK+ where windows can have (very colourful) backgrounds
3275 defined by a user's selected theme.
3276
3277 Dialogs, notebook pages and the status bar have this flag set to true
3278 by default so that the default look and feel is simulated best.

3349 \membersection{wxWindow::SetWindowStyleFlag}\label{wxwindowsetwindowstyleflag}
3350
3351 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
3352
3353 Sets the style of the window. Please note that some styles cannot be changed
3354 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
3355 be called after changing the others for the change to take place immediately.

3365
3366 \func{void}{SetWindowVariant}{\param{wxWindowVariant}{variant}}
3367
3368 This function can be called under all platforms but only does anything under
3369 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3370 exist in several sizes which correspond to the elements of wxWindowVariant
3371 enum:
3372 \begin{verbatim}
3373 enum wxWindowVariant
3374 {
3375 wxWINDOW_VARIANT_NORMAL, // Normal size
3376 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3377 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3378 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3379 };
3380 \end{verbatim}
3381
3382 By default the controls use the normal size, of course, but this function can
3383 be used to change this.

3389
3390 Return \true from here to allow the colours of this window to be changed by
3391 \helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3392 forbids inheriting them from the parent window.
3393
3394 The base class version returns \false, but this method is overridden in
3395 \helpref{wxControl}{wxcontrol} where it returns \true.
3396
3397
3398 \membersection{wxWindow::Show}\label{wxwindowshow}
3399
3400 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3401
3402 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3403 for a top level window if you want to bring it to top, although this is not
3404 needed if Show() is called immediately after the frame creation.
3405
3406 \wxheading{Parameters}
3407
3408 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3409
3410 \wxheading{Return value}
3411
3412 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
3413 done because it already was in the requested state.

3426 Reenables window updating after a previous call to

3428 exactly the same number of times as \helpref{Freeze}{wxwindowfreeze}.

3435 Transfers values from child controls to data areas specified by their validators. Returns
3436 {\tt false} if a transfer failed.
3437
3438 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,

3490
3491 \func{virtual void}{Update}{\void}
3492
3493 Calling this method immediately repaints the invalidated area of the window and
3494 all of its children recursively while this would usually only happen when the
3495 flow of control returns to the event loop. Notice that this function doesn't
3496 refresh the window and does nothing if the window hadn't been already
3497 repainted. Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3498 immediately redraw the window unconditionally.
3499
3500
3501 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3502
3503 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3504
3505 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3506 the window. The particular implementation depends on the window; for
3507 example a wxToolBar will send an update UI event for each toolbar button,
3508 and a wxFrame will send an update UI event for each menubar menu item.
3509 You can call this function from your application to ensure that your
3510 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3511 are concerned). This may be necessary if you have called
3512 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3513 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3514 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3515
3516 {\it flags} should be a bitlist of one or more of the following values.
3517
3518 \begin{verbatim}
3519 enum wxUpdateUI
3520 {
3521 wxUPDATE_UI_NONE = 0x0000, // No particular value
3522 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3523 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3524 };
3525 \end{verbatim}
3526
3527 If you are calling this function from an OnInternalIdle or OnIdle
3528 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3529 this tells the window to only update the UI elements that need
3530 to be updated in idle time. Some windows update their elements
3531 only when necessary, for example when a menu is about to be shown.
3532 The following is an example of how to call UpdateWindowUI from
3533 an idle function.
3534
3535 \begin{verbatim}
3536 void MyWindow::OnInternalIdle()
3537 {
3538 if (wxUpdateUIEvent::CanUpdate(this))
3539 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
