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, wxWindows 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, wxWindows 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.}

118 \param{const wxPoint\& }{pos = wxDefaultPosition},
119 \param{const wxSize\& }{size = wxDefaultSize},
120 \param{long }{style = 0},
121 \param{const wxString\& }{name = wxPanelNameStr}}
122
123 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
124
125 \wxheading{Parameters}
126
127 \docparam{parent}{Pointer to a parent window.}
128
129 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
130
131 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
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 wxWindows
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 wxWindows
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 wxWindows 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 wxWindows 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.

243 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
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

317
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

474
475 \func{virtual void}{DoUpdateWindowUI}{\param{wxUpdateUIEvent\&}{ event}}
476
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, wxWindows

517
518 \func{virtual bool}{Enable}{\param{bool}{ enable = {\tt true}}}
519
520 Enable or disable the window for user input. Note that when a parent window is
521 disabled, all of its children are disabled as well and they are reenabled again
522 when the parent is.
523
524 \wxheading{Parameters}

620 \membersection{wxWindow::Fit}\label{wxwindowfit}
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());
632 \end{verbatim}
633
634 instead of calling Fit.

636
637 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}
638
639 \func{virtual void}{FitInside}{\void}
640
641 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
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.
646
647
648 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}
649
650 \func{virtual void}{Freeze}{\void}
651
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 wxWindows and not a mandatory

682 \constfunc{wxSize}{GetAdjustedBestSize}{\void}
683
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
688 be drawn at, not the minimal size it can possibly tolerate.

707
708 This functions returns the best acceptable minimal size for the window. For
709 example, for a static control, it will be the minimal size such that the
710 control label is not truncated. For windows containing subwindows (typically
711 \helpref{wxPanel}{wxpanel}), the size returned by this function will be the
712 same as the size the window would have had after calling
713 \helpref{Fit}{wxwindowfit}.

759
760 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
761
762 Returns the default font and colours which are used by the control. This is
763 useful if you want to use the same font or colour in your own control as in a
764 standard control -- which is a much better idea than hard coding specific
765 colours or fonts which might look completely out of place on the users
766 system, especially if it uses themes.
767
768 The \arg{variant} parameter is only relevant under Mac currently and is
769 ignore under other platforms. Under Mac, it will change the size of the
770 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
771 for more about this.
772
773 This static method is ``overridden'' in many derived classes and so calling,
774 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
775 return the values appropriate for a button which will be normally different
776 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
777
778 The \texttt{wxVisualAttributes} structure has at least the fields
779 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
780 if it was not possible to determine the default control appearance or,
781 especially for the background colour, if the field doesn't make sense as is
782 the case for \texttt{colBg} for the controls with themed background.

846
847 \constfunc{virtual wxVisualAttributes}{GetDefaultAttributes}{\void}
848
849 Currently this is the same as calling
850 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
851
852 One advantage of using this function compared to the static version is that
853 the call is automatically dispatched to the correct class (as usual with
854 virtual functions) and you don't have to specify the class name explicitly.
855
856 The other one is that in the future this function could return different
857 results, for example it might return a different font for an ``Ok'' button
858 than for a generic button if the users GUI is configured to show such buttons
859 in bold font. Of course, the down side is that it is impossible to call this
860 function without actually having an object to apply it to whereas the static
861 version can be used without having to create an object first.

2013 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows

2279
2280 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2281 be called automatically when the window is resized. It is called implicitly by
2282 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2283 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2284 manually or otherwise the window layout won't be correctly updated when its
2285 size changes.
2286
2287 \wxheading{Parameters}

2303 \wxheading{Parameters}
2304
2305 \docparam{colour}{The colour to be used as the background colour.}
2306
2307 \wxheading{Remarks}
2308
2309 The background colour is usually painted by the default\rtfsp
2310 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2311 under Windows and automatically under GTK.
2312
2313 Note that setting the background colour does not cause an immediate refresh, so you
2314 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2315 calling this function.
2316
2317 Use this function with care under GTK+ as the new appearance of the window might
2318 not look equally well when used with "Themes", i.e GTK+'s ability to change its
2319 look as the user wishes with run-time loadable modules.

2342 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2343
2344 This sets the size of the window client area in pixels. Using this function to size a window
2345 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2346 worry about what dimensions the border or title bar have when trying to fit the window
2347 around panel items, for example.
2348

2370 This normally does not need to be called by user code. It is called

2372 remove itself from the sizer when it is destroyed.

2379 % VZ: the docs are correct, if the code doesn't behave like this, it must be

2381 Sets the window's cursor. Notice that the window cursor also sets it for the
2382 children of the window implicitly.
2383
2384 The {\it cursor} may be {\tt wxNullCursor} in which case the window cursor will
2385 be reset back to default.

2398 \func{void}{SetConstraints}{\param{wxLayoutConstraints* }{constraints}}
2399
2400 Sets the window to have the given layout constraints. The window
2401 will then own the object, and will take care of its deletion.
2402 If an existing layout constraints object is already owned by the
2403 window, it will be deleted.
2404
2405 \wxheading{Parameters}
2406
2407 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2408 constraints.}
2409
2410 \wxheading{Remarks}
2411
2412 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2413 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2414 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2415 sizer will have effect.

2439 \wxheading{Parameters}
2440
2441 \docparam{handler}{Specifies the handler to be set.}
2442
2443 \wxheading{Remarks}
2444
2445 An event handler is an object that is capable of processing the events
2446 sent to a window. By default, the window is its own event handler, but
2447 an application may wish to substitute another, for example to allow
2448 central implementation of event-handling for a variety of different
2449 window classes.
2450
2451 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2452 this sets up a chain of event handlers, where an event not handled by one event handler is
2453 handed to the next one in the chain.

2471 \twocolwidtha{5cm}%
2472 \begin{twocollist}\itemsep=0pt
2473 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
2474 and Validate() methods will recursively descend into all children of the
2475 window if it has this style flag set.}
2476 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2477 events are propagated upwards to the window parent recursively until a handler
2478 for them is found. Using this style allows to prevent them from being
2479 propagated beyond this window. Notice that wxDialog has this style on by
2480 default for the reasons explained in the
2481 \helpref{event processing overview}{eventprocessing}.}
2482 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2483 window from being used as an implicit parent for the dialogs which were
2484 created without a parent. It is useful for the windows which can disappear at
2485 any moment as creating children of such windows results in fatal problems.}
2486 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
2487 caption. When pressed, Windows will go into a context-sensitive help mode and wxWindows will send
2488 a wxEVT\_HELP event if the user clicked on an application window.
2489 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2490 you should use the style of
2491 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the
2492 frames having this style (the dialogs don't have minimize nor maximize box by

2641 Let's say you wish to display 50 lines of text, using the same font.
2642 The window is sized so that you can only see 16 lines at a time.
2643
2644 You would use:
2645
2646 {\small%
2647 \begin{verbatim}
2648 SetScrollbar(wxVERTICAL, 0, 16, 50);
2649 \end{verbatim}
2650 }
2651
2652 Note that with the window at this size, the thumb position can never go
2653 above 50 minus 16, or 34.
2654
2655 You can determine how many lines are currently visible by dividing the current view
2656 size by the character height in pixels.
2657
2658 When defining your own scrollbar behaviour, you will always need to recalculate
2659 the scrollbar settings when the window size changes. You could therefore put your
2660 scrollbar calculations and SetScrollbar
2661 call into a function named AdjustScrollbars, which can be called initially and also
2662 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2677
2678 \wxheading{Parameters}
2679
2680 \docparam{orientation}{Determines the scrollbar whose page size is to be set. May be wxHORIZONTAL or wxVERTICAL.}
2681
2682 \docparam{pageSize}{Page size in scroll units.}
2683
2684 \docparam{refresh}{{\tt true} to redraw the scrollbar, {\tt false} otherwise.}
2685
2686 \wxheading{Remarks}
2687
2688 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2689 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2690 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2691 value has to be adjusted when the window is resized, since the page size will have changed.
2692
2693 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2694 the thumb changes size to reflect the page size relative to the length of the document. When the
2695 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2696 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2697 disappear.
2698
2699 Currently, this function should be called before SetPageRange, because of a quirk in the Windows

2754 \wxheading{Remarks}
2755
2756 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2757 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2758 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2759 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2760 and usually the scrollbar will be automatically hidden.

2876 Sets the window to have the given layout sizer. The window
2877 will then own the object, and will take care of its deletion.
2878 If an existing layout constraints object is already owned by the
2879 window, it will be deleted if the deleteOld parameter is true.
2880
2881 Note that this function will also call

2931 This function tells a window if it should use the system's "theme" code
2932 to draw the windows' background instead if its own background drawing
2933 code. This does not always have any effect since the underlying platform
2934 obviously needs to support the notion of themes in user defined windows.
2935 One such platform is GTK+ where windows can have (very colourful) backgrounds
2936 defined by a user's selected theme.
2937
2938 Dialogs, notebook pages and the status bar have this flag set to true

3021 This function can be called under all platforms but only does anything under
3022 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3023 exist in several sizes which correpond to the elements of wxWindowVariant
3024 enum:
3025 \begin{verbatim}
3026 enum wxWindowVariant
3027 {

3029 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )

3031 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3032 };

3132
3133 Calling this method immediately repaints the invalidated area of the window
3134 while this would usually only happen when the flow of control returns to the
3135 event loop. Notice that this function doesn't refresh the window and does
3136 nothing if the window hadn't been already repainted. Use
3137 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3138 window unconditionally.

3141 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3142
3143 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3144
3145 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3146 the window. The particular implementation depends on the window; for
3147 example a wxToolBar will send an update UI event for each toolbar button,
3148 and a wxFrame will send an update UI event for each menubar menu item.
3149 You can call this function from your application to ensure that your
3150 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3151 are concerned). This may be necessary if you have called
3152 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3153 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3154 limit the overhead that wxWindows incurs by sending update UI events in idle time.
3155
3156 {\it flags} should be a bitlist of one or more of the following values.
3157
3158 \begin{verbatim}
3159 enum wxUpdateUI
3160 {
3161 wxUPDATE_UI_NONE = 0x0000, // No particular value
3162 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3163 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3164 };
3165 \end{verbatim}
3166
3167 If you are calling this function from an OnInternalIdle or OnIdle
3168 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3169 this tells the window to only update the UI elements that need
3170 to be updated in idle time. Some windows update their elements
3171 only when necessary, for example when a menu is about to be shown.
3172 The following is an example of how to call UpdateWindowUI from
3173 an idle function.
3174
3175 \begin{verbatim}
3176 void MyWindow::OnInternalIdle()
3177 {
3178 if (wxUpdateUIEvent::CanUpdate(this))
