3 wxWindow is the base class for all windows. Any children of the window will be deleted
4 automatically by the destructor before the window itself is deleted.
5
6 %Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
7 %help text. These must not be called by a user program and are documented only for illustration.
8 %On several platforms, only a few of these handlers are actually written (they are not always
9 %needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
10 %the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
11 %platform can implement its native behaviour or just ignore the event if nothing needs to be
12 %done.

26 window class or on all platforms.

37 events. Windows only.}
38 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
39 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that the window
40 wants to get all char events - even for keys like TAB or ENTER which are
41 usually used for dialog navigation and which wouldn't be generated without
42 this style}
43 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
44 the window completely when its size is changed - you will have to repaint the
45 new window area manually if you use this style. Currently only has an effect for
46 Windows.}
47 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
48 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
49 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}{If a window has scrollbars,
50 disable them instead of hiding them when they are not needed (i.e. when the
51 size of the window is big enough to not require the scrollbars to navigate it).
52 This style is currently only implemented for wxMSW and wxUniversal and does
53 nothing on the other platforms.}
54 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
55 repainted, then children being painted over them. Windows only.}

82 \docparam{parent}{Pointer to a parent window.}
83
84 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
85
86 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
87 should generate a default position for the window. If using the wxWindow class directly, supply
88 an actual position.}
89
90 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
91 should generate a default size for the window. If no suitable size can be found, the

99 \membersection{wxWindow::\destruct{wxWindow}}
100
101 \func{}{\destruct{wxWindow}}{\void}
102
103 Destructor. Deletes all subwindows, then deletes itself. Instead of using
104 the {\bf delete} operator explicitly, you should normally
105 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
106 can delete a window only when it is safe to do so, in idle time.

114 \membersection{wxWindow::AddChild}
115
116 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
117
118 Adds a child window. This is called automatically by window creation
119 functions so should not be required by the application programmer.
120
121 \wxheading{Parameters}
122
123 \docparam{child}{Child window to add.}
124
125 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
126
127 \func{virtual void}{CaptureMouse}{\void}
128
129 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
130 release the capture.
131
132 Note that wxWindows maintains the stack of windows having captured the mouse
133 and when the mouse is released the capture returns to the window which had had
134 captured it previously and it is only really released if there were no previous
135 window. In particular, this means that you must release the mouse as many times
136 as you capture it.

161
162 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
163
164 Centres the window.
165
166 \wxheading{Parameters}
167
168 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

174 (it has no effect).
175

197 \wxheading{Remarks}
198
199 This methods provides for a way to center top level windows over their
200 parents instead of the entire screen. If there is no parent or if the
201 window is not a top level window, then behaviour is the same as
202 \helpref{wxWindow::Centre}{wxwindowcentre}.

211
212 Centres the window on screen. This only works for top level windows -
213 otherwise, the window will still be centered on its parent.
214
215 \wxheading{Parameters}

240 Converts to screen coordinates from coordinates relative to this window.
241
242 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
243 a screen coordinate will be passed out.}

257
258 \membersection{wxWindow::Close}\label{wxwindowclose}
259
260 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
261
262 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
263 handler usually tries to close the window. It doesn't close the window itself,
264 however.
265
266 \wxheading{Parameters}
267
268 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
269 of this window, {\tt true} if it cannot.}
270
271 \wxheading{Remarks}
272
273 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
274 an opportunity for the window to choose whether to destroy the window.
275 Usually it is only used with the top level windows (wxFrame and wxDialog
276 classes) as the others are not supposed to have any special OnClose() logic.
277
278 The close handler should check whether the window is being deleted forcibly,
279 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
280 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
281
282 {\it Note} that calling Close does not guarantee that the window will be
283 destroyed; but it provides a way to simulate a manual close of a window, which
284 may or may not be implemented by destroying the window. The default
285 implementation of wxDialog::OnCloseWindow does not necessarily delete the
286 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
287 the appropriate button event handler and may do anything at all.
288
289 To guarantee that the window will be destroyed, call
290 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

299
300 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
301
302 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
303
304 Converts a point or size from dialog units to pixels.
305
306 For the x dimension, the dialog units are multiplied by the average character width
307 and then divided by 4.
308
309 For the y dimension, the dialog units are multiplied by the average character height
310 and then divided by 8.
311
312 \wxheading{Remarks}
313
314 Dialog units are used for maintaining a dialog's proportions even if the font changes.
315 Dialogs created using Dialog Editor optionally use dialog units.
316
317 You can also use these functions programmatically. A convenience macro is defined:
318
319 {\small
320 \begin{verbatim}
321 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

382 Destroys the window safely. Use this function instead of the delete operator, since
383 different window classes can be destroyed differently. Frames and dialogs
384 are not destroyed immediately when this function is called -- they are added
385 to a list of windows to be deleted on idle time, when all the window's events
386 have been processed. This prevents problems with events being sent to non-existent
387 windows.
388

524
525 \func{virtual void}{Fit}{\void}
526
527 Sizes the window so that it fits around its subwindows. This function won't do
528 anything if there are no subwindows and will only really work correctly if the
529 sizers are used for the subwindows layout. Also, if the window has exactly one
530 subwindow it is better (faster and the result is more precise as Fit adds some
531 margin to account for fuzziness of its calculations) to call
532
533 \begin{verbatim}

540
541 \func{virtual void}{FitInside}{\void}
542
543 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
544 of a window. Mainly useful with scrolled windows to reset scrollbars after
545 sizing changes that do not trigger a size event, and/or scrolled windows without
546 an interior sizer. This function similarly won't do anything if there are no
547 subwindows.

1987 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
1988 be called automatically when the window is resized. It is called implicitly by
1989 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
1990 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
1991 manually or otherwise the window layout won't be correctly updated when its

2010
2011 \docparam{colour}{The colour to be used as the background colour.}
2012
2013 \wxheading{Remarks}
2014
2015 The background colour is usually painted by the default\rtfsp
2016 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2017 under Windows and automatically under GTK.
2018
2019 Note that setting the background colour does not cause an immediate refresh, so you
2020 may wish to call \helpref{wxWindow::Clear}{wxwindowclear} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2021 calling this function.
2022
2023 Use this function with care under GTK as the new appearance of the window might
2024 not look equally well when used with "Themes", i.e GTK's ability to change its
2025 look as the user wishes with run-time loadable modules.

2047
2048 This sets the size of the window client area in pixels. Using this function to size a window
2049 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2050 worry about what dimensions the border or title bar have when trying to fit the window
2051 around panel items, for example.

2102 will then own the object, and will take care of its deletion.
2103 If an existing layout constraints object is already owned by the
2104 window, it will be deleted.
2105
2106 \wxheading{Parameters}

2108 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2109 constraints.}
2110
2111 \wxheading{Remarks}
2112
2113 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2114 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2115 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2149 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2150 this sets up a chain of event handlers, where an event not handled by one event handler is
2151 handed to the next one in the chain.

2173 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2174 events are propagated upwards to the window parent recursively until a handler
2175 for them is found. Using this style allows to prevent them from being
2176 propagated beyond this window. Notice that wxDialog has this style on by
2177 default for the reasons explained in the
2178 \helpref{event processing overview}{eventprocessing}.}
2179 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2180 window from being used as an implicit parent for the dialogs which were
2181 created without a parent. It is useful for the windows which can disappear at
2182 any moment as creating children of such windows results in fatal problems.}
2183 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
2184 caption. When pressed, Windows will go into a context-sensitive help mode and wxWindows will send
2185 a wxEVT\_HELP event if the user clicked on an application window.
2186 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2187 you should use the style of
2188 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the

2207 This function is called by wxWindows keyboard navigation code when the user
2208 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2209 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

2324 Let's say you wish to display 50 lines of text, using the same font.
2325 The window is sized so that you can only see 16 lines at a time.
2326
2327 You would use:
2328
2329 {\small%
2330 \begin{verbatim}
2331 SetScrollbar(wxVERTICAL, 0, 16, 50);
2332 \end{verbatim}
2333 }
2334
2335 Note that with the window at this size, the thumb position can never go
2336 above 50 minus 16, or 34.
2337
2338 You can determine how many lines are currently visible by dividing the current view
2339 size by the character height in pixels.
2340
2341 When defining your own scrollbar behaviour, you will always need to recalculate
2342 the scrollbar settings when the window size changes. You could therefore put your
2343 scrollbar calculations and SetScrollbar
2344 call into a function named AdjustScrollbars, which can be called initially and also
2345 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2368
2369 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2370 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2371 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2372 value has to be adjusted when the window is resized, since the page size will have changed.
2373
2374 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2375 the thumb changes size to reflect the page size relative to the length of the document. When the
2376 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2377 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2378 disappear.
2379
2380 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2381 handling of pages and ranges.

2433
2434 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2435 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2436 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2437 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2438 and usually the scrollbar will be automatically hidden.

2663
2664 \func{void}{SetWindowStyle}{\param{long}{ style}}
2665
2666 Identical to \helpref{SetWindowStyleFlag}{wxwindowsetwindowstyleflag}.
2667
2668 \membersection{wxWindow::SetWindowStyleFlag}\label{wxwindowsetwindowstyleflag}
2669
2670 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
2671
2672 Sets the style of the window. Please note that some styles cannot be changed
2673 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
2674 be called after changing the others for the change to take place immediately.

2682 \membersection{wxWindow::Show}\label{wxwindowshow}
2683
2684 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
2685
2686 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
2687 for a top level window if you want to bring it to top, although this is not
2688 needed if Show() is called immediately after the frame creation.
2689
2690 \wxheading{Parameters}
2691
2692 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
2693
2694 \wxheading{Return value}
2695
2696 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
2697 done because it already was in the requested state.

2712 \func{virtual bool}{TransferDataFromWindow}{\void}
2713
2714 Transfers values from child controls to data areas specified by their validators. Returns
2715 {\tt false} if a transfer failed.
2716
2717 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
2718 the method will also call TransferDataFromWindow() of all child windows.

2746
2747 Calling this method immediately repaints the invalidated area of the window
2748 while this would usually only happen when the flow of control returns to the
2749 event loop. Notice that this function doesn't refresh the window and does
2750 nothing if the window hadn't been already repainted. Use
2751 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
2752 window unconditionally.
2753
2754 \membersection{wxWindow::Validate}\label{wxwindowvalidate}
2755
2756 \func{virtual bool}{Validate}{\void}
2757
2758 Validates the current values of the child controls using their validators.
2759
2760 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
2761 the method will also call Validate() of all child windows.
2762
2763 \wxheading{Return value}
