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.

25 The following styles can apply to all windows, although they will not always make sense for a particular
26 window class or on all platforms.

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

64
65 \func{}{wxWindow}{\void}
66
67 Default constructor.
68
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},
73 \param{const wxString\& }{name = wxPanelNameStr}}
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.

182 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
183
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

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.}

243 a screen coordinate will be passed out.}
244
245 \docparam{pt}{The client position for the second form of the function.}
246

254
255 \membersection{wxWindow::Close}\label{wxwindowclose}
256
257 \func{virtual bool}{Close}{\param{bool}{ force = {\tt FALSE}}}
258
259 The purpose of this call is to provide a safer way of destroying a window than using
260 the {\it delete} operator.
261
262 \wxheading{Parameters}
263
264 \docparam{force}{{\tt FALSE} if the window's close handler should be able to veto the destruction
265 of this window, {\tt TRUE} if it cannot.}
266
267 \wxheading{Remarks}
268
269 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
270 choose whether to destroy the window.
271
272 The close handler should check whether the window is being deleted forcibly,
273 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
274 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
275
276 Applies to managed windows (wxFrame and wxDialog classes) only.
277
278 {\it Note} that calling Close does not guarantee that the window will be destroyed; but it
279 provides a way to simulate a manual close of a window, which may or may not be implemented by
280 destroying the window. The default implementation of wxDialog::OnCloseWindow does not
281 necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
282 itself only hides the dialog.
283
284 To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead.

294 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
295
296 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
297
298 Converts a point or size from dialog units to pixels.
299
300 For the x dimension, the dialog units are multiplied by the average character width
301 and then divided by 4.
302
303 For the y dimension, the dialog units are multiplied by the average character height
304 and then divided by 8.
305
306 \wxheading{Remarks}
307
308 Dialog units are used for maintaining a dialog's proportions even if the font changes.
309 Dialogs created using Dialog Editor optionally use dialog units.
310
311 You can also use these functions programmatically. A convenience macro is defined:
312
313 {\small
314 \begin{verbatim}
315 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

373

375
376 Destroys the window safely. Use this function instead of the delete operator, since
377 different window classes can be destroyed differently. Frames and dialogs
378 are not destroyed immediately when this function is called - they are added
379 to a list of windows to be deleted on idle time, when all the window's events
380 have been processed. This prevents problems with events being sent to non-existant
381 windows.
382

472
473 Freezes the window or, in other words, prevents any updates from taking place
474 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
475 be called to reenable window redrawing.
476
477 This method is useful for visual appearance optimization (for example, it
478 is a good idea to use it before inserting large amount of text into a
479 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
480 controls so it is mostly just a hint to wxWindows and not a mandatory

499 This functions returns the best acceptable minimal size for the window. For
500 example, for a static control, it will be the minimal size such that the
501 control label is not truncated. For windows containing subwindows (typically
502 \helpref{wxPanel}{wxpanel}), the size returned by this function will be the

1193 %%
1194 %% This is an event handler function called when the user has tried to close a a frame
1195 %% or dialog box using the window manager (X) or system menu (Windows). It is
1196 %% called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1197 %% that the application can also invoke the handler programmatically.
1198 %%
1199 %% Use the EVT\_CLOSE event table macro to handle close events.
1200 %%
1201 %% You should check whether the application is forcing the deletion of the window
1202 %% using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is {\tt TRUE},
1203 %% destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1204 %% If not, it is up to you whether you respond by destroying the window.
1205 %%
1206 %% (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1207 %% the window is required, test for the negative of CanVeto. If CanVeto returns {\tt FALSE},
1208 %% it is not possible to skip window deletion.)
1209 %%
1210 %% If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1211 %% let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function

1952 \docparam{colour}{The colour to be used as the background colour.}

1962 calling this function.
1963
1964 Use this function with care under GTK as the new appearance of the window might

1989 This sets the size of the window client area in pixels. Using this function to size a window
1990 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not

2244 Let's say you wish to display 50 lines of text, using the same font.
2245 The window is sized so that you can only see 16 lines at a time.
2246
2247 You would use:
2248
2249 {\small%
2250 \begin{verbatim}
2251 SetScrollbar(wxVERTICAL, 0, 16, 50);
2252 \end{verbatim}
2253 }
2254
2255 Note that with the window at this size, the thumb position can never go
2256 above 50 minus 16, or 34.
2257
2258 You can determine how many lines are currently visible by dividing the current view
2259 size by the character height in pixels.
2260
2261 When defining your own scrollbar behaviour, you will always need to recalculate
2262 the scrollbar settings when the window size changes. You could therefore put your
2263 scrollbar calculations and SetScrollbar
2264 call into a function named AdjustScrollbars, which can be called initially and also
2265 from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

2286
2287 \wxheading{Remarks}
2288
2289 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2290 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2291 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2292 value has to be adjusted when the window is resized, since the page size will have changed.
2293
2294 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2295 the thumb changes size to reflect the page size relative to the length of the document. When the
2296 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2297 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2298 disappear.
2299
2300 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2301 handling of pages and ranges.

2352 \wxheading{Remarks}
2353
2354 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2355 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2356 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2357 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2358 and usually the scrollbar will be automatically hidden.
