2
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.

30 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
31 for this style. }

37 events. Windows only.}
38 \twocolitem{\windowstyle{wxNO\_3D}}{Prevents the children of this window taking on 3D styles, even though
39 the application-wide policy is for 3D controls. Windows only.}
40 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
41 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that the window
42 wants to get all char events - even for keys like TAB or ENTER which are
43 usually used for dialog navigation and which wouldn't be generated without
44 this style}
45 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
46 the window completely when its size is changed - you will have to repaint the
47 new window area manually if you use this style. Currently only has an effect for
48 Windows.}

50 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
51 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being

69 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
70 \param{const wxPoint\& }{pos = wxDefaultPosition},
71 \param{const wxSize\& }{size = wxDefaultSize},
72 \param{long }{style = 0},

74
75 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
76
77 \wxheading{Parameters}
78
79 \docparam{parent}{Pointer to a parent window.}
80
81 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
82
83 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
84 should generate a default position for the window. If using the wxWindow class directly, supply
85 an actual position.}
86
87 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
88 should generate a default size for the window. If no suitable size can be found, the
89 window will be sized to 20x20 pixels so that the window is visible but obviously not
90 correctly sized. }
91
92 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
93
94 \docparam{name}{Window name.}
95
96 \membersection{wxWindow::\destruct{wxWindow}}
97
98 \func{}{\destruct{wxWindow}}{\void}
99
100 Destructor. Deletes all subwindows, then deletes itself. Instead of using
101 the {\bf delete} operator explicitly, you should normally
102 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
103 can delete a window only when it is safe to do so, in idle time.

111 \membersection{wxWindow::AddChild}
112
113 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
114
115 Adds a child window. This is called automatically by window creation
116 functions so should not be required by the application programmer.
117
118 \wxheading{Parameters}
119
120 \docparam{child}{Child window to add.}
121
122 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
123
124 \func{virtual void}{CaptureMouse}{\void}
125
126 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
127 release the capture.
128
129 Note that wxWindows maintains the stack of windows having captured the mouse
130 and when the mouse is released the capture returns to the window which had had
131 captured it previously and it is only really released if there were no previous
132 window. In particular, this means that you must release the mouse as many times
133 as you capture it.

156
157 \membersection{wxWindow::Centre}\label{wxwindowcentre}
158
159 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
160
161 Centres the window.
162
163 \wxheading{Parameters}
164
165 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
166 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
167 if you want to center the window on the entire screen and not on its
168 parent window.}
169
170 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
171 (it has no effect).
172
173 \wxheading{Remarks}
174
175 If the window is a top level one (i.e. doesn't have a parent), it will be
176 centered relative to the screen anyhow.

184 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
185
186 Centres the window on its parent. This is a more readable synonym for
187 \helpref{Centre}{wxwindowcentre}.
188
189 \wxheading{Parameters}
190
191 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
192 or {\tt wxBOTH}.}
193
194 \wxheading{Remarks}
195
196 This methods provides for a way to center top level windows over their
197 parents instead of the entire screen. If there is no parent or if the
198 window is not a top level window, then behaviour is the same as
199 \helpref{wxWindow::Centre}{wxwindowcentre}.

207 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
208
209 Centres the window on screen. This only works for top level windows -
210 otherwise, the window will still be centered on its parent.
211
212 \wxheading{Parameters}
213
214 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

233 modifying its parameters.}
234
235 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
236
237 Converts to screen coordinates from coordinates relative to this window.
238
239 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
240 a screen coordinate will be passed out.}
241
242 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
243 a screen coordinate will be passed out.}
244
245 \docparam{pt}{The client position for the second form of the function.}
246
247 \pythonnote{In place of a single overloaded method name, wxPython
248 implements the following methods:\par

254
255 \membersection{wxWindow::Close}\label{wxwindowclose}
256
257 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
258
259 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
260 handler usually tries to close the window. It doesn't close the window itself,
261 however.
262
263 \wxheading{Parameters}
264
265 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
266 of this window, {\tt true} if it cannot.}
267
268 \wxheading{Remarks}
269
270 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
271 an opportunity for the window to choose whether to destroy the window.
272 Usually it is only used with the top level windows (wxFrame and wxDialog
273 classes) as the others are not supposed to have any special OnClose() logic.
274
275 The close handler should check whether the window is being deleted forcibly,
276 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
277 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
278
279 {\it Note} that calling Close does not guarantee that the window will be
280 destroyed; but it provides a way to simulate a manual close of a window, which
281 may or may not be implemented by destroying the window. The default
282 implementation of wxDialog::OnCloseWindow does not necessarily delete the
283 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
284 the appropriate button event handler and may do anything at all.
285
286 To guarantee that the window will be destroyed, call
287 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

296
297 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
298
299 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
300
301 Converts a point or size from dialog units to pixels.
302
303 For the x dimension, the dialog units are multiplied by the average character width
304 and then divided by 4.
305
306 For the y dimension, the dialog units are multiplied by the average character height
307 and then divided by 8.
308
309 \wxheading{Remarks}
310
311 Dialog units are used for maintaining a dialog's proportions even if the font changes.
312 Dialogs created using Dialog Editor optionally use dialog units.
313
314 You can also use these functions programmatically. A convenience macro is defined:
315
316 {\small
317 \begin{verbatim}
318 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

376
377 \func{virtual bool}{Destroy}{\void}
378
379 Destroys the window safely. Use this function instead of the delete operator, since
380 different window classes can be destroyed differently. Frames and dialogs
381 are not destroyed immediately when this function is called -- they are added
382 to a list of windows to be deleted on idle time, when all the window's events
383 have been processed. This prevents problems with events being sent to non-existent
384 windows.
385
386 \wxheading{Return value}

523
524 Sizes the window so that it fits around its subwindows. This function won't do
525 anything if there are no subwindows.
526
527 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}

529 \func{virtual void}{FitInside}{\void}
530
531 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
532 of a window. Mainly useful with scrolled windows to reset scrollbars after
533 sizing changes that do not trigger a size event, and/or scrolled windows without
534 an interior sizer. This function similarly won't do anything if there are no
535 subwindows.
536
537 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}
538
539 \func{virtual void}{Freeze}{\void}
540
541 Freezes the window or, in other words, prevents any updates from taking place
542 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
543 be called to reenable window redrawing.
544
545 This method is useful for visual appearance optimization (for example, it
546 is a good idea to use it before inserting large amount of text into a
547 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
548 controls so it is mostly just a hint to wxWindows and not a mandatory

555 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
556 in one thing. GetBestSize should return the minimum untruncated size of the
557 window, while this method will return the largest of BestSize and any user
558 specified minimum size. ie. it is the minimum size the window should currently
559 be drawn at, not the minimal size it can possibly tolerate.

1955
1956 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
1957 be called automatically when the window is resized. It is called implicitly by
1958 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
1959 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
1960 manually or otherwise the window layout won't be correctly updated when its

1978 \wxheading{Parameters}
1979
1980 \docparam{colour}{The colour to be used as the background colour.}
1981
1982 \wxheading{Remarks}
1983
1984 The background colour is usually painted by the default\rtfsp
1985 \helpref{wxEraseEvent}{wxeraseevent} event handler function
1986 under Windows and automatically under GTK.
1987
1988 Note that setting the background colour does not cause an immediate refresh, so you
1989 may wish to call \helpref{wxWindow::Clear}{wxwindowclear} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
1990 calling this function.
1991
1992 Use this function with care under GTK as the new appearance of the window might
1993 not look equally well when used with "Themes", i.e GTK's ability to change its
1994 look as the user wishes with run-time loadable modules.

2015 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2016
2017 This sets the size of the window client area in pixels. Using this function to size a window
2018 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2019 worry about what dimensions the border or title bar have when trying to fit the window

2072 If an existing layout constraints object is already owned by the

2293 Let's say you wish to display 50 lines of text, using the same font.
2294 The window is sized so that you can only see 16 lines at a time.
2295
2296 You would use:
2297
2298 {\small%
2299 \begin{verbatim}
2300 SetScrollbar(wxVERTICAL, 0, 16, 50);
2301 \end{verbatim}
2302 }
2303
2304 Note that with the window at this size, the thumb position can never go
2305 above 50 minus 16, or 34.
2306
2307 You can determine how many lines are currently visible by dividing the current view
2308 size by the character height in pixels.
2309
2310 When defining your own scrollbar behaviour, you will always need to recalculate
2311 the scrollbar settings when the window size changes. You could therefore put your
2312 scrollbar calculations and SetScrollbar
2313 call into a function named AdjustScrollbars, which can be called initially and also
2314 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2336 \wxheading{Remarks}
2337
2338 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2339 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2340 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2341 value has to be adjusted when the window is resized, since the page size will have changed.
2342
2343 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2344 the thumb changes size to reflect the page size relative to the length of the document. When the
2345 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2346 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2347 disappear.
2348
2349 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2350 handling of pages and ranges.

2402
2403 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2404 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2405 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2406 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2407 and usually the scrollbar will be automatically hidden.

2648 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
2649
2650 Sets the style of the window. Please note that some styles cannot be changed
2651 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
2652 be called after changing the others for the change to take place immediately.
2653
2654 See \helpref{Window styles}{windowstyles} for more information about flags.

2661
2662 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
2663
2664 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
2665 for a top level window if you want to bring it to top, although this is not
2666 needed if Show() is called immediately after the frame creation.
2667
2668 \wxheading{Parameters}
2669
2670 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
2671
2672 \wxheading{Return value}
2673
2674 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
2675 done because it already was in the requested state.

2690 \func{virtual bool}{TransferDataFromWindow}{\void}
2691
2692 Transfers values from child controls to data areas specified by their validators. Returns
2693 {\tt false} if a transfer failed.
2694
2695 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
2696 the method will also call TransferDataFromWindow() of all child windows.

2724
2725 Calling this method immediately repaints the invalidated area of the window
2726 while this would usually only happen when the flow of control returns to the
2727 event loop. Notice that this function doesn't refresh the window and does
2728 nothing if the window hadn't been already repainted. Use
2729 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
2730 window unconditionally.
2731
2732 \membersection{wxWindow::Validate}\label{wxwindowvalidate}
2733
2734 \func{virtual bool}{Validate}{\void}
2735
2736 Validates the current values of the child controls using their validators.
2737
2738 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
2739 the method will also call Validate() of all child windows.
2740
2741 \wxheading{Return value}
2742
