3 wxWindow is the base class for all windows. Any
4 children of the window will be deleted automatically by the destructor
5 before the window itself is deleted.

49
50 \func{}{wxWindow}{\void}
51
52 Default constructor.
53
54 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
55 \param{const wxPoint\& }{pos = wxDefaultPosition},
56 \param{const wxSize\& }{size = wxDefaultSize},
57 \param{long }{style = 0},
58 \param{const wxString\& }{name = wxPanelNameStr}}
59
60 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
61
62 \wxheading{Parameters}
63
64 \docparam{parent}{Pointer to a parent window.}
65
66 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
67
68 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
69 should generate a default position for the window. If using the wxWindow class directly, supply
70 an actual position.}
71
72 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
73 should generate a default size for the window. If no suitable size can be found, the
74 window will be sized to 20x20 pixels so that the window is visible but obviously not
75 correctly sized. }
76
77 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
78
79 \docparam{name}{Window name.}
80
81 \membersection{wxWindow::\destruct{wxWindow}}
82
83 \func{}{\destruct{wxWindow}}{\void}
84
85 Destructor. Deletes all subwindows, then deletes itself. Instead of using
86 the {\bf delete} operator explicitly, you should normally
87 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
88 can delete a window only when it is safe to do so, in idle time.

97 \membersection{wxWindow::AddChild}
98
99 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
100
101 Adds a child window. This is called automatically by window creation
102 functions so should not be required by the application programmer.

130
131 \membersection{wxWindow::Centre}\label{wxwindowcentre}
132
133 \func{void}{Centre}{\param{int}{ direction = wxHORIZONTAL}}
134
135 Centres the window.
136
137 \wxheading{Parameters}
138
139 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
140 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
141 if you want to center the window on the entire screen and not on its
142 parent window.}
143
144 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer.
145
146 \wxheading{Remarks}
147
148 If the window is a top level one (i.e. doesn't have a parent), it will be
149 centered relative to the screen anyhow.

155 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
156
157 \func{void}{CentreOnParent}{\param{int}{ direction = wxHORIZONTAL}}
158
159 Centres the window.
160
161 \wxheading{Parameters}
162
163 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
164 or {\tt wxBOTH}.}
165
166 \wxheading{Remarks}
167
168 This methods provides for a way to center top level windows over their
169 parents instead of the entire screen. If there is no parent or if the
170 window is not a top level window, then behaviour is the same as
171 \helpref{wxWindow::Centre}{wxwindowcentre}.

179 \func{void}{Clear}{\void}
180
181 Clears the window by filling it with the current background colour. Does not
182 cause an erase background event to be generated.
183
184 \membersection{wxWindow::ClientToScreen}
185
186 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
187
188 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
189
190 Converts to screen coordinates from coordinates relative to this window.
191
192 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
193 a screen coordinate will be passed out.}
194
195 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
196 a screen coordinate will be passed out.}
197
198 \docparam{pt}{The client position for the second form of the function.}

205 \end{twocollist}}
206 }
207
208
209 \membersection{wxWindow::Close}\label{wxwindowclose}
210
211 \func{virtual bool}{Close}{\param{const bool}{ force = FALSE}}
212
213 The purpose of this call is to provide a safer way of destroying a window than using
214 the {\it delete} operator.
215
216 \wxheading{Parameters}
217
218 \docparam{force}{FALSE if the window's close handler should be able to veto the destruction
219 of this window, TRUE if it cannot.}
220
221 \wxheading{Remarks}
222
223 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
224 choose whether to destroy the window.
225
226 The close handler should check whether the window is being deleted forcibly,
227 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
228 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
229
230 Applies to managed windows (wxFrame and wxDialog classes) only.
231
232 {\it Note} that calling Close does not guarantee that the window will be destroyed; but it
233 provides a way to simulate a manual close of a window, which may or may not be implemented by
234 destroying the window. The default implementation of wxDialog::OnCloseWindow does not
235 necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
236 itself only hides the dialog.
237
238 To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead.

248
249 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
250
251 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
252
253 Converts a point or size from dialog units to pixels.
254
255 For the x dimension, the dialog units are multiplied by the average character width
256 and then divided by 4.
257
258 For the y dimension, the dialog units are multiplied by the average character height
259 and then divided by 8.
260
261 \wxheading{Remarks}
262
263 Dialog units are used for maintaining a dialog's proportions even if the font changes.
264 Dialogs created using Dialog Editor optionally use dialog units.
265
266 You can also use these functions programmatically. A convenience macro is defined:
267
268 {\small
269 \begin{verbatim}
270 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
271 \end{verbatim}

299 \func{wxSize}{ConvertPixelsToDialog}{\param{const wxSize\&}{ sz}}
300
301 Converts a point or size from pixels to dialog units.
302
303 For the x dimension, the pixels are multiplied by 4 and then divided by the average
304 character width.
305
306 For the y dimension, the pixels are multipled by 8 and then divided by the average
307 character height.

328
329 \func{virtual bool}{Destroy}{\void}
330
331 Destroys the window safely. Use this function instead of the delete operator, since
332 different window classes can be destroyed differently. Frames and dialogs
333 are not destroyed immediately when this function is called - they are added
334 to a list of windows to be deleted on idle time, when all the window's events
335 have been processed. This prevents problems with events being sent to non-existant
336 windows.
337
338 \wxheading{Return value}
339
340 TRUE if the window has either been successfully deleted, or it has been added
341 to the list of windows pending real deletion.

928
929 This member function is called in response to a keypress. To intercept this event,
930 use the EVT\_CHAR macro in an event table definition. Your {\bf OnChar} handler may call this
931 default function to achieve default keypress functionality.
932
933 Note that the ASCII values do not have explicit key codes: they are passed as ASCII
934 values.
935
936 Note that not all keypresses can be intercepted this way. If you wish to intercept modifier
937 keypresses, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
938 \helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.

953 before they are processed by child windows.
954
955 \wxheading{Parameters}
956
957 \docparam{event}{Object containing keypress information. See \helpref{wxKeyEvent}{wxkeyevent} for
958 details about this class.}
959
960 \wxheading{Remarks}
961
962 This member function is called in response to a keypress, if the window is active. To intercept this event,
963 use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
964 keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
965
966 An example of using this function is in the implementation of escape-character processing for wxDialog,
967 where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
968
969 Note that the ASCII values do not have explicit key codes: they are passed as ASCII
970 values.
971
972 This function is only relevant to top-level windows (frames and dialogs), and under
973 Windows only. Under GTK the normal EVT\_CHAR\_ event has the functionality, i.e.
974 you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip}
975 the window won't get the event.

1012
1013 {\bf Note:} This is an obsolete function.

1033
1034 This is an event handler function called when the user has tried to close a a frame
1035 or dialog box using the window manager (X) or system menu (Windows). It is
1036 called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1037 that the application can also invoke the handler programmatically.
1038
1039 Use the EVT\_CLOSE event table macro to handle close events.
1040
1041 You should check whether the application is forcing the deletion of the window
1042 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1043 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1044 If not, it is up to you whether you respond by destroying the window.
1045
1046 (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1047 the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1048 it is not possible to skip window deletion.)
1049
1050 If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1051 let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1052 to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1053
1054 \wxheading{Remarks}
1055
1056 The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1057 for backward compatibility with earlier versions of wxWindows. The
1058 default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1059 destroying the window if it returns TRUE or if the close is being forced.

1133 default function to achieve default keypress functionality.
1134
1135 Note that not all keypresses can be intercepted this way. If you wish to intercept special
1136 keys, such as shift, control, and function keys, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
1137 \helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.
1138
1139 Most, but not all, windows allow keypresses to be intercepted.

1255 pressed.
1256
1257 \wxheading{Parameters}

1332 Sent to the event handler when the window must be refreshed.
1333
1334 \wxheading{Parameters}
1335
1336 \docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
1337
1338 \wxheading{Remarks}
1339
1340 Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1341
1342 In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
1343
1344 For example:
1345
1346 \small{%
1347 \begin{verbatim}
1348 void MyWindow::OnPaint(wxPaintEvent& event)
1349 {
1350 wxPaintDC dc(this);
1351
1352 DrawMyDocument(dc);
1353 }
1354 \end{verbatim}
1355 }%
1356
1357 You can optimize painting by retrieving the rectangles
1358 that have been damaged and only repainting these. The rectangles are in
1359 terms of the client area, and are unscrolled, so you will need to do
1360 some calculations using the current view position to obtain logical,
1361 scrolled units.
1362
1363 Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
1364
1365 {\small%
1366 \begin{verbatim}
1367 // Called when window needs to be repainted.
1368 void MyWindow::OnPaint(wxPaintEvent& event)
1369 {
1370 wxPaintDC dc(this);
1371
1372 // Find Out where the window is scrolled to
1373 int vbX,vbY; // Top left corner of client
1374 ViewStart(&vbX,&vbY);
1375
1376 int vX,vY,vW,vH; // Dimensions of client area in pixels
1377 wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
1378
1379 while (upd)
1380 {
1381 vX = upd.GetX();
1382 vY = upd.GetY();
1383 vW = upd.GetW();
1384 vH = upd.GetH();
1385
1386 // Alternatively we can do this:
1387 // wxRect rect;
1388 // upd.GetRect(&rect);
1389
1390 // Repaint this rectangle
1391 ...some code...
1392
1393 upd ++ ;
1394 }
1395 }
1396 \end{verbatim}

1557 An event handler is an object that is capable of processing the events
1558 sent to a window. By default, the window is its own event handler, but
1559 an application may wish to substitute another, for example to allow
1560 central implementation of event-handling for a variety of different
1561 window classes.
1562
1563 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1564 an application to set up a chain of event handlers, where an event not handled by one event handler is
1565 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

1714
1715 \docparam{colour}{The colour to be used as the background colour.}
1716
1717 \wxheading{Remarks}
1718
1719 The background colour is usually painted by the default\rtfsp
1720 \helpref{wxWindow::OnEraseBackground}{wxwindowonerasebackground} event handler function
1721 under Windows and automatically under GTK.
1722
1723 Note that setting the background colour does not cause an immediate refresh, so you

1746 This sets the size of the window client area in pixels. Using this function to size a window
1747 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
1748 worry about what dimensions the border or title bar have when trying to fit the window

1790
1791 \docparam{handler}{Specifies the handler to be set.}
1792
1793 \wxheading{Remarks}
1794
1795 An event handler is an object that is capable of processing the events
1796 sent to a window. By default, the window is its own event handler, but
1797 an application may wish to substitute another, for example to allow
1798 central implementation of event-handling for a variety of different
1799 window classes.
1800
1801 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
1802 this sets up a chain of event handlers, where an event not handled by one event handler is
1803 handed to the next one in the chain.

1951 Let's say you wish to display 50 lines of text, using the same font.
1952 The window is sized so that you can only see 16 lines at a time.
1953
1954 You would use:
1955
1956 {\small%
1957 \begin{verbatim}
1958 SetScrollbar(wxVERTICAL, 0, 16, 50);
1959 \end{verbatim}
1960 }
1961
1962 Note that with the window at this size, the thumb position can never go
1963 above 50 minus 16, or 34.
1964
1965 You can determine how many lines are currently visible by dividing the current view
1966 size by the character height in pixels.
1967
1968 When defining your own scrollbar behaviour, you will always need to recalculate
1969 the scrollbar settings when the window size changes. You could therefore put your
1970 scrollbar calculations and SetScrollbar
1971 call into a function named AdjustScrollbars, which can be called initially and also
1972 from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

1993
1994 \wxheading{Remarks}
1995
1996 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
1997 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
1998 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
1999 value has to be adjusted when the window is resized, since the page size will have changed.
2000
2001 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2002 the thumb changes size to reflect the page size relative to the length of the document. When the
2003 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2004 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2005 disappear.
2006
2007 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2008 handling of pages and ranges.

2061 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2062 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2063 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2064 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2065 and usually the scrollbar will be automatically hidden.
