1 \section{\class{wxWindow}}\label{wxwindow}
2
3 wxWindow is the base class for all windows and represents any visible objecto n
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},

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}}
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}
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::CaptureMouse}\label{wxwindowcapturemouse}
177
178 \func{virtual void}{CaptureMouse}{\void}
179
180 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
181 release the capture.
182
183 Note that wxWidgets maintains the stack of windows having captured the mouse
184 and when the mouse is released the capture returns to the window which had had
185 captured it previously and it is only really released if there were no previous
186 window. In particular, this means that you must release the mouse as many times
187 as you capture it.

214
215 \membersection{wxWindow::Centre}\label{wxwindowcentre}
216
217 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
218
219 Centres the window.
220
221 \wxheading{Parameters}
222
223 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
224 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
225 if you want to center the window on the entire screen and not on its
226 parent window.}
227
228 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
229 (it has no effect).
230
231 \wxheading{Remarks}
232
233 If the window is a top level one (i.e. doesn't have a parent), it will be
234 centered relative to the screen anyhow.

244
245 Centres the window on its parent. This is a more readable synonym for
246 \helpref{Centre}{wxwindowcentre}.
247
248 \wxheading{Parameters}
249
250 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
251 or {\tt wxBOTH}.}
252
253 \wxheading{Remarks}
254
255 This methods provides for a way to center top level windows over their
256 parents instead of the entire screen. If there is no parent or if the
257 window is not a top level window, then behaviour is the same as
258 \helpref{wxWindow::Centre}{wxwindowcentre}.

266
267 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
268
269 Centres the window on screen. This only works for top level windows -
270 otherwise, the window will still be centered on its parent.
271
272 \wxheading{Parameters}
273
274 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

318 \membersection{wxWindow::Close}\label{wxwindowclose}
319
320 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
321
322 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
323 handler usually tries to close the window. It doesn't close the window itself,
324 however.
325
326 \wxheading{Parameters}
327
328 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
329 of this window, {\tt true} if it cannot.}
330
331 \wxheading{Remarks}
332
333 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
334 an opportunity for the window to choose whether to destroy the window.
335 Usually it is only used with the top level windows (wxFrame and wxDialog
336 classes) as the others are not supposed to have any special OnClose() logic.
337
338 The close handler should check whether the window is being deleted forcibly,
339 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
340 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
341
342 {\it Note} that calling Close does not guarantee that the window will be
343 destroyed; but it provides a way to simulate a manual close of a window, which
344 may or may not be implemented by destroying the window. The default
345 implementation of wxDialog::OnCloseWindow does not necessarily delete the
346 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
347 the appropriate button event handler and may do anything at all.
348
349 To guarantee that the window will be destroyed, call
350 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

360
361 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
362
363 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
364
365 Converts a point or size from dialog units to pixels.
366
367 For the x dimension, the dialog units are multiplied by the average character width
368 and then divided by 4.
369
370 For the y dimension, the dialog units are multiplied by the average character height
371 and then divided by 8.
372
373 \wxheading{Remarks}
374
375 Dialog units are used for maintaining a dialog's proportions even if the font changes.
376
377 You can also use these functions programmatically. A convenience macro is defined:
378
379 {\small
380 \begin{verbatim}
381 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

441 Destroys the window safely. Use this function instead of the delete operator, since
442 different window classes can be destroyed differently. Frames and dialogs
443 are not destroyed immediately when this function is called -- they are added
444 to a list of windows to be deleted on idle time, when all the window's events
445 have been processed. This prevents problems with events being sent to non-existent
446 windows.
447

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

621
622 \func{virtual void}{Fit}{\void}
623
624 Sizes the window so that it fits around its subwindows. This function won't do
625 anything if there are no subwindows and will only really work correctly if the
626 sizers are used for the subwindows layout. Also, if the window has exactly one
627 subwindow it is better (faster and the result is more precise as Fit adds some
628 margin to account for fuzziness of its calculations) to call
629
630 \begin{verbatim}
631 window->SetClientSize(child->GetSize());

642 of a window. Mainly useful with scrolled windows to reset scrollbars after
643 sizing changes that do not trigger a size event, and/or scrolled windows without
644 an interior sizer. This function similarly won't do anything if there are no
645 subwindows.

648 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

652 Freezes the window or, in other words, prevents any updates from taking place
653 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
654 be called to reenable window redrawing. Calls to these two functions may be
655 nested.
656
657 This method is useful for visual appearance optimization (for example, it
658 is a good idea to use it before inserting large amount of text into a
659 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
660 controls so it is mostly just a hint to wxWidgets and not a mandatory

684 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
685 in one thing. GetBestSize should return the minimum untruncated size of the
686 window, while this method will return the largest of BestSize and any user
687 specified minimum size. ie. it is the minimum size the window should currently

721 This functions returns the best acceptable minimal size for the window. For
722 example, for a static control, it will be the minimal size such that the
723 control label is not truncated. For windows containing subwindows (typically
724 \helpref{wxPanel}{wxpanel}), the size returned by this function will be the
725 same as the size the window would have had after calling

772
773 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
774
775 Returns the default font and colours which are used by the control. This is
776 useful if you want to use the same font or colour in your own control as in a
777 standard control -- which is a much better idea than hard coding specific
778 colours or fonts which might look completely out of place on the users
779 system, especially if it uses themes.
780
781 The \arg{variant} parameter is only relevant under Mac currently and is
782 ignore under other platforms. Under Mac, it will change the size of the
783 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
784 for more about this.
785
786 This static method is ``overridden'' in many derived classes and so calling,
787 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
788 return the values appropriate for a button which will be normally different
789 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
790
791 The \texttt{wxVisualAttributes} structure has at least the fields
792 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
793 if it was not possible to determine the default control appearance or,
794 especially for the background colour, if the field doesn't make sense as is
795 the case for \texttt{colBg} for the controls with themed background.

865
866 Currently this is the same as calling
867 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
868
869 One advantage of using this function compared to the static version is that
870 the call is automatically dispatched to the correct class (as usual with
871 virtual functions) and you don't have to specify the class name explicitly.
872
873 The other one is that in the future this function could return different
874 results, for example it might return a different font for an ``Ok'' button
875 than for a generic button if the users GUI is configured to show such buttons
876 in bold font. Of course, the down side is that it is impossible to call this
877 function without actually having an object to apply it to whereas the static
878 version can be used without having to create an object first.

1286 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1287
1288 \func{void}{InheritAttributes}{\void}
1289
1290 This function is (or should be, in case of custom controls) called during
1291 window creation to intelligently set up the window visual attributes, that is
1292 the font and the foreground and background colours.
1293
1294 By ``intelligently'' the following is meant: by default, all windows use their
1295 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1296 if some of the parents attributes are explicitly (that is, using
1297 \helpref{SetFont}{wxwindowsetfont} and not
1298 \helpref{SetDefaultFont}{wxwindowsetdefaultfont}) changed \emph{and} if the
1299 corresponding attribute hadn't been explicitly set for this window itself,
1300 then this window takes the same value as used by the parent. In addition, if
1301 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1302 to return \false, the colours will not be changed no matter what and only the
1303 font might.
1304
1305 This rather complicated logic is necessary in order to accomodate the
1306 different usage scenarius. The most common one is when all default attributes
1307 are used and in this case, nothing should be inherited as in modern GUIs
1308 different controls use different fonts (and colours) than their siblings so
1309 they can't inherit the same value from the parent. However it was also deemed
1310 desirable to allow to simply change the attributes of all children at once by
1311 just changing the font or colour of their common parent, hence in this case we
1312 do inherit the parents attributes.

2081
2082 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows

2348
2349 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2350 be called automatically when the window is resized. It is called implicitly by
2351 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2352 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2353 manually or otherwise the window layout won't be correctly updated when its
2354 size changes.
2355
2356 \wxheading{Parameters}
2357
2358 \docparam{autoLayout}{Set this to {\tt true} if you wish the Layout function to be called

2370 Sets the background colour of the window.
2371
2372 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2373 explanation of the difference between this method and
2374 \helpref{SetDefaultBackgroundColour}{wxwindowsetdefaultbackgroundcolour}.
2375
2376 \wxheading{Parameters}
2377
2378 \docparam{colour}{The colour to be used as the background colour, pass
2379 {\tt wxNullColour} to reset to the default colour.}
2380
2381 \wxheading{Remarks}
2382
2383 The background colour is usually painted by the default\rtfsp
2384 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2385 under Windows and automatically under GTK.
2386
2387 Note that setting the background colour does not cause an immediate refresh, so you
2388 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2389 calling this function.
2390
2391 Using this function will disable attempts to use themes for this
2392 window, if the system supports them. Use with care since usually the
2393 themes represent the appearance chosen by the user to be used for all
2394 applications on the system.

2410
2411 A {\it smart} SetSize that will fill in default size components with the
2412 window's {\it best} size values. Also sets the window's minsize to
2413 the value passed in for use with sizers. This means that if a full or

2436
2437 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2438
2439 This sets the size of the window client area in pixels. Using this function to size a window
2440 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2441 worry about what dimensions the border or title bar have when trying to fit the window
2442 around panel items, for example.
2443

2445

2496 will then own the object, and will take care of its deletion.
2497 If an existing layout constraints object is already owned by the
2498 window, it will be deleted.

2502 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2503 constraints.}
2504
2505 \wxheading{Remarks}
2506
2507 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2508 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2509 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2574
2575 \docparam{handler}{Specifies the handler to be set.}
2576
2577 \wxheading{Remarks}
2578
2579 An event handler is an object that is capable of processing the events
2580 sent to a window. By default, the window is its own event handler, but
2581 an application may wish to substitute another, for example to allow
2582 central implementation of event-handling for a variety of different
2583 window classes.
2584
2585 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2586 this sets up a chain of event handlers, where an event not handled by one event handler is
2587 handed to the next one in the chain.

2610 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command

2614 default for the reasons explained in the

2616 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a

2624 you should use the style of
2625 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the

2788 Let's say you wish to display 50 lines of text, using the same font.
2789 The window is sized so that you can only see 16 lines at a time.
2790
2791 You would use:
2792
2793 {\small%
2794 \begin{verbatim}
2795 SetScrollbar(wxVERTICAL, 0, 16, 50);
2796 \end{verbatim}
2797 }
2798
2799 Note that with the window at this size, the thumb position can never go
2800 above 50 minus 16, or 34.
2801
2802 You can determine how many lines are currently visible by dividing the current view
2803 size by the character height in pixels.
2804
2805 When defining your own scrollbar behaviour, you will always need to recalculate
2806 the scrollbar settings when the window size changes. You could therefore put your
2807 scrollbar calculations and SetScrollbar
2808 call into a function named AdjustScrollbars, which can be called initially and also
2809 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2832
2833 \wxheading{Remarks}
2834
2835 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2836 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2837 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2838 value has to be adjusted when the window is resized, since the page size will have changed.
2839
2840 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2841 the thumb changes size to reflect the page size relative to the length of the document. When the
2842 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2843 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2844 disappear.
2845
2846 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2847 handling of pages and ranges.

2901 \wxheading{Remarks}
2902
2903 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2904 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2905 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2906 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2907 and usually the scrollbar will be automatically hidden.

3090 code. This does not always have any effect since the underlying platform

3092 One such platform is GTK+ where windows can have (very colourful) backgrounds
3093 defined by a user's selected theme.

3210 forbids inheriting them from the parent window.
3211
3212 The base class version returns \false, but this method is overridden in
3213 \helpref{wxControl}{wxcontrol} where it returns \true.

3218 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3219
3220 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3221 for a top level window if you want to bring it to top, although this is not
3222 needed if Show() is called immediately after the frame creation.

3225
3226 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3227
3228 \wxheading{Return value}
3229
3230 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
3231 done because it already was in the requested state.

3243 Reenables window updating after a previous call to

3251
3252 Transfers values from child controls to data areas specified by their validators. Returns
3253 {\tt false} if a transfer failed.
3254
3255 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3256 the method will also call TransferDataFromWindow() of all child windows.

3307
3308 \func{virtual void}{Update}{\void}
3309
3310 Calling this method immediately repaints the invalidated area of the window
3311 while this would usually only happen when the flow of control returns to the
3312 event loop. Notice that this function doesn't refresh the window and does
3313 nothing if the window hadn't been already repainted. Use
3314 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3315 window unconditionally.

3318 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3319
3320 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3321
3322 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3323 the window. The particular implementation depends on the window; for
3324 example a wxToolBar will send an update UI event for each toolbar button,
3325 and a wxFrame will send an update UI event for each menubar menu item.
3326 You can call this function from your application to ensure that your
3327 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3328 are concerned). This may be necessary if you have called
3329 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3330 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3331 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3332
3333 {\it flags} should be a bitlist of one or more of the following values.
3334
3335 \begin{verbatim}
3336 enum wxUpdateUI
3337 {
3338 wxUPDATE_UI_NONE = 0x0000, // No particular value
3339 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3340 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3341 };
3342 \end{verbatim}
3343
3344 If you are calling this function from an OnInternalIdle or OnIdle
3345 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3346 this tells the window to only update the UI elements that need
3347 to be updated in idle time. Some windows update their elements
3348 only when necessary, for example when a menu is about to be shown.
3349 The following is an example of how to call UpdateWindowUI from
3350 an idle function.
3351
3352 \begin{verbatim}
3353 void MyWindow::OnInternalIdle()
3354 {
3355 if (wxUpdateUIEvent::CanUpdate(this))
3356 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3357 }

3372
3373 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3374 the method will also call Validate() of all child windows.
3375
3376 \wxheading{Return value}
