1 \section{\class{wxWindow}}\label{wxwindow}
2
3 wxWindow is the base class for all windows and represents any visible object on
4 screen. All controls, top level windows and so on are windows. Sizers and
5 device contexts are not, however, as they don't appear on screen themselves.
6
7 Please note that all children of the window will be deleted automatically by
8 the destructor before the window itself is deleted which means that you don't
9 have to worry about deleting them manually. Please see the \helpref{window
10 deletion overview}{windowdeletionoverview} for more information.
11
12 Also note that in this, and many others, wxWidgets classes some
13 \texttt{GetXXX()} methods may be overloaded (as, for example,
14 \helpref{GetSize}{wxwindowgetsize} or
15 \helpref{GetClientSize}{wxwindowgetclientsize}). In this case, the overloads
16 are non-virtual because having multiple virtual functions with the same name
17 results in a virtual function name hiding at the derived class level (in
18 English, this means that the derived class has to override all overloaded
19 variants if it overrides any of them). To allow overriding them in the derived
20 class, wxWidgets uses a unique protected virtual \texttt{DoGetXXX()} method
21 and all \texttt{GetXXX()} ones are forwarded to it, so overriding the former
22 changes the behaviour of the latter.

33 \wxheading{Window styles}
34
35 The following styles can apply to all windows, although they will not always make sense for a particular
36 window class or on all platforms.
37
38 \twocolwidtha{5cm}%
39 \begin{twocollist}\itemsep=0pt
40 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
41 for this style. }
42 \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows and Mac only.}
43 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
44 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border.}
45 \twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control. Windows only. }
46 \twocolitem{\windowstyle{wxNO\_BORDER}}{Displays no border, overriding the default border style for the window.}
47 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
48 events. Windows only.}
49 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
50 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
51 the window wants to get all char/key events for all keys - even for
52 keys like TAB or ENTER which are usually used for dialog navigation
53 and which wouldn't be generated without this style. If you need to
54 use this style in order to get the arrows or etc., but would still like to have
55 normal keyboard navigation take place, you should create and send a
56 wxNavigationKeyEvent in response to the key events for Tab and
57 Shift-Tab.}
58 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
59 the window completely when its size is changed - you will have to repaint the
60 new window area manually if you use this style. Currently only has an effect for
61 Windows.}
62 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
63 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
64 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
65 disable them instead of hiding them when they are not needed (i.e. when the
66 size of the window is big enough to not require the scrollbars to navigate it).
67 This style is currently only implemented for wxMSW and wxUniversal and does
68 nothing on the other platforms.}
69 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
70 repainted, then children being painted over them. Windows only.}
71 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
72 a complete redraw of the window whenever it is resized instead of redrawing
73 just the part of the window affected by resizing. Note that this was the
74 behaviour by default before 2.5.1 release and that if you experience redraw
75 problems with the code which previously used to work you may want to try this.}

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

114
115 Default constructor.
116
117 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
118 \param{const wxPoint\& }{pos = wxDefaultPosition},
119 \param{const wxSize\& }{size = wxDefaultSize},
120 \param{long }{style = 0},
121 \param{const wxString\& }{name = wxPanelNameStr}}
122
123 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
124
125 \wxheading{Parameters}
126
127 \docparam{parent}{Pointer to a parent window.}
128
129 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
130
131 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWidgets
132 should generate a default position for the window. If using the wxWindow class directly, supply
133 an actual position.}
134
135 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWidgets
136 should generate a default size for the window. If no suitable size can be found, the
137 window will be sized to 20x20 pixels so that the window is visible but obviously not
138 correctly sized. }
139
140 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
141
142 \docparam{name}{Window name.}
143
144
145 \membersection{wxWindow::\destruct{wxWindow}}
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.

159
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.

213
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}}

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

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

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());

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.

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

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 wxWidgets and not a mandatory

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

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.

864 \constfunc{virtual wxVisualAttributes}{GetDefaultAttributes}{\void}
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{SetOwnFont}{wxwindowsetownfont}) 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.

2104 An event handler is an object that is capable of processing the events

2107 central implementation of event-handling for a variety of different
2108 window classes.
2109
2110 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows

2167 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2168 will receive a hotkey event. It will receive the event even if the application is in the background
2169 and does not have the input focus because the user is working with some other application.
2170
2171 \wxheading{Parameters}
2172
2173 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If
2174 this function is called from a shared DLL, it must be a system wide unique identifier between 0xC000 and 0xFFFF.
2175 This is a MSW specific detail.}
2176
2177 \docparam{modifiers}{A bitwise combination of {\tt wxMOD\_SHIFT}, {\tt wxMOD\_CONTROL}, {\tt wxMOD\_ALT}

2376
2377 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2378 be called automatically when the window is resized. It is called implicitly by
2379 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2380 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2381 manually or otherwise the window layout won't be correctly updated when its
2382 size changes.
2383
2384 \wxheading{Parameters}
2385
2386 \docparam{autoLayout}{Set this to {\tt true} if you wish the Layout function to be called

2400 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2401 explanation of the difference between this method and
2402 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2403
2404 \wxheading{Parameters}
2405
2406 \docparam{colour}{The colour to be used as the background colour, pass
2407 {\tt wxNullColour} to reset to the default colour.}
2408
2409 \wxheading{Remarks}
2410
2411 The background colour is usually painted by the default\rtfsp
2412 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2413 under Windows and automatically under GTK.
2414
2415 Note that setting the background colour does not cause an immediate refresh, so you
2416 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2417 calling this function.
2418
2419 Using this function will disable attempts to use themes for this
2420 window, if the system supports them. Use with care since usually the
2421 themes represent the appearance chosen by the user to be used for all
2422 applications on the system.

2438
2439 A {\it smart} SetSize that will fill in default size components with the
2440 window's {\it best} size values. Also sets the window's minsize to
2441 the value passed in for use with sizers. This means that if a full or

2465 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2466
2467 This sets the size of the window client area in pixels. Using this function to size a window
2468 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2469 worry about what dimensions the border or title bar have when trying to fit the window
2470 around panel items, for example.

2524 will then own the object, and will take care of its deletion.
2525 If an existing layout constraints object is already owned by the
2526 window, it will be deleted.
2527
2528 \wxheading{Parameters}
2529
2530 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2531 constraints.}
2532
2533 \wxheading{Remarks}
2534
2535 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2536 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2537 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2602
2603 \docparam{handler}{Specifies the handler to be set.}
2604
2605 \wxheading{Remarks}
2606
2607 An event handler is an object that is capable of processing the events
2608 sent to a window. By default, the window is its own event handler, but
2609 an application may wish to substitute another, for example to allow
2610 central implementation of event-handling for a variety of different
2611 window classes.
2612
2613 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2614 this sets up a chain of event handlers, where an event not handled by one event handler is
2615 handed to the next one in the chain.

2638 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command

2642 default for the reasons explained in the
2643 \helpref{event processing overview}{eventprocessing}.}
2644 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a

2652 you should use the style of

2815
2816 Let's say you wish to display 50 lines of text, using the same font.
2817 The window is sized so that you can only see 16 lines at a time.
2818
2819 You would use:
2820
2821 {\small%
2822 \begin{verbatim}
2823 SetScrollbar(wxVERTICAL, 0, 16, 50);
2824 \end{verbatim}
2825 }
2826
2827 Note that with the window at this size, the thumb position can never go
2828 above 50 minus 16, or 34.
2829
2830 You can determine how many lines are currently visible by dividing the current view
2831 size by the character height in pixels.
2832
2833 When defining your own scrollbar behaviour, you will always need to recalculate
2834 the scrollbar settings when the window size changes. You could therefore put your
2835 scrollbar calculations and SetScrollbar
2836 call into a function named AdjustScrollbars, which can be called initially and also
2837 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2860
2861 \wxheading{Remarks}
2862
2863 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2864 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2865 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2866 value has to be adjusted when the window is resized, since the page size will have changed.
2867
2868 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2869 the thumb changes size to reflect the page size relative to the length of the document. When the
2870 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2871 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2872 disappear.
2873
2874 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2875 handling of pages and ranges.

2930
2931 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2932 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2933 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2934 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2935 and usually the scrollbar will be automatically hidden.

3118 code. This does not always have any effect since the underlying platform

3120 One such platform is GTK+ where windows can have (very colourful) backgrounds
3121 defined by a user's selected theme.

3212 \func{void}{SetWindowVariant}{\param{wxWindowVariant}{variant}}
3213
3214 This function can be called under all platforms but only does anything under
3215 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3216 exist in several sizes which correpond to the elements of wxWindowVariant
3217 enum:
3218 \begin{verbatim}
3219 enum wxWindowVariant
3220 {
3221 wxWINDOW_VARIANT_NORMAL, // Normal size
3222 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3223 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3224 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3225 };
3226 \end{verbatim}
3227
3228 By default the controls use the normal size, of course, but this function can
3229 be used to change this.

3232 \membersection{wxWindow::ShouldInheritColours}\label{wxwindowshouldinheritcolours}
3233
3234 \func{virtual bool}{ShouldInheritColours}{\void}
3235
3236 Return \true from here to allow the colours of this window to be changed by
3237 \helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3238 forbids inheriting them from the parent window.
3239
3240 The base class version returns \false, but this method is overridden in
3241 \helpref{wxControl}{wxcontrol} where it returns \true.

3244 \membersection{wxWindow::Show}\label{wxwindowshow}
3245
3246 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3247
3248 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3249 for a top level window if you want to bring it to top, although this is not
3250 needed if Show() is called immediately after the frame creation.
3251
3252 \wxheading{Parameters}
3253
3254 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3255
3256 \wxheading{Return value}
3257
3258 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
3259 done because it already was in the requested state.

3270
3271 Reenables window updating after a previous call to
3272 \helpref{Freeze}{wxwindowfreeze}. To really thaw the control, it must be called
3273 exactly the same number of times as \helpref{Freeze}{wxwindowfreeze}.

3279
3280 Transfers values from child controls to data areas specified by their validators. Returns
3281 {\tt false} if a transfer failed.
3282
3283 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3284 the method will also call TransferDataFromWindow() of all child windows.

3318
3319 \docparam{hotkeyId}{Numeric identifier of the hotkey. Must be the same id that was passed to RegisterHotKey.}

3334 \membersection{wxWindow::Update}\label{wxwindowupdate}
3335
3336 \func{virtual void}{Update}{\void}
3337
3338 Calling this method immediately repaints the invalidated area of the window
3339 while this would usually only happen when the flow of control returns to the
3340 event loop. Notice that this function doesn't refresh the window and does
3341 nothing if the window hadn't been already repainted. Use
3342 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3343 window unconditionally.

3346 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3347
3348 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3349
3350 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3351 the window. The particular implementation depends on the window; for
3352 example a wxToolBar will send an update UI event for each toolbar button,
3353 and a wxFrame will send an update UI event for each menubar menu item.
3354 You can call this function from your application to ensure that your
3355 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3356 are concerned). This may be necessary if you have called
3357 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3358 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3359 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3360
3361 {\it flags} should be a bitlist of one or more of the following values.
3362
3363 \begin{verbatim}
3364 enum wxUpdateUI
3365 {
3366 wxUPDATE_UI_NONE = 0x0000, // No particular value
3367 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3368 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3369 };
3370 \end{verbatim}
3371
3372 If you are calling this function from an OnInternalIdle or OnIdle
3373 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3374 this tells the window to only update the UI elements that need
3375 to be updated in idle time. Some windows update their elements
3376 only when necessary, for example when a menu is about to be shown.
3377 The following is an example of how to call UpdateWindowUI from
3378 an idle function.
3379
3380 \begin{verbatim}
3381 void MyWindow::OnInternalIdle()
3382 {
3383 if (wxUpdateUIEvent::CanUpdate(this))
3384 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3385 }

3395 \membersection{wxWindow::Validate}\label{wxwindowvalidate}
3396
3397 \func{virtual bool}{Validate}{\void}
3398
3399 Validates the current values of the child controls using their validators.
3400
3401 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3402 the method will also call Validate() of all child windows.
3403
3404 \wxheading{Return value}
3405
3406 Returns {\tt false} if any of the validations failed.
