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.}
74
75 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
76
77 \docparam{name}{Window name.}
78
79 \membersection{wxWindow::\destruct{wxWindow}}
80
81 \func{}{\destruct{wxWindow}}{\void}
82
83 Destructor. Deletes all subwindows, then deletes itself. Instead of using
84 the {\bf delete} operator explicitly, you should normally
85 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
86 can delete a window only when it is safe to do so, in idle time.

94
95 \membersection{wxWindow::AddChild}
96
97 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
98
99 Adds a child window. This is called automatically by window creation
100 functions so should not be required by the application programmer.
101
102 \wxheading{Parameters}
103
104 \docparam{child}{Child window to add.}
105
106 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
107
108 \func{virtual void}{CaptureMouse}{\void}
109
110 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
111 release the capture.

117 \membersection{wxWindow::Center}\label{wxwindowcenter}
118
119 \func{void}{Center}{\param{int}{ direction}}
120
121 A synonym for \helpref{Centre}{wxwindowcentre}.
122
123 \membersection{wxWindow::Centre}\label{wxwindowcentre}
124
125 \func{virtual void}{Centre}{\param{int}{ direction = wxHORIZONTAL}}
126
127 Centres the window.
128
129 \wxheading{Parameters}
130
131 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
132 or {\tt wxBOTH}.}
133
134 \wxheading{Remarks}
135
136 The actual behaviour depends on the derived window. For a frame or dialog box,
137 centring is relative to the whole display. For a panel item, centring is
138 relative to the panel.

144 \membersection{wxWindow::Clear}\label{wxwindowclear}
145
146 \func{void}{Clear}{\void}
147
148 Clears the window by filling it with the current background colour. Does not
149 cause an erase background event to be generated.
150
151 \membersection{wxWindow::ClientToScreen}
152
153 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
154
155 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
156
157 Converts to screen coordinates from coordinates relative to this window.
158
159 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
160 a screen coordinate will be passed out.}
161
162 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
163 a screen coordinate will be passed out.}
164
165 \docparam{pt}{The client position for the second form of the function.}
166
167 \pythonnote{In place of a single overloaded method name, wxPython
168 implements the following methods:\par
169 \indented{2cm}{\begin{twocollist}
170 \twocolitem{\bf{ClientToScreen(point)}}{Accepts and returns a wxPoint}

174
175
176 \membersection{wxWindow::Close}\label{wxwindowclose}
177
178 \func{virtual bool}{Close}{\param{const bool}{ force = FALSE}}
179
180 The purpose of this call is to provide a safer way of destroying a window than using
181 the {\it delete} operator.
182
183 \wxheading{Parameters}
184
185 \docparam{force}{FALSE if the window's close handler should be able to veto the destruction
186 of this window, TRUE if it cannot.}
187
188 \wxheading{Remarks}
189
190 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
191 choose whether to destroy the window.
192
193 The close handler should check whether the window is being deleted forcibly,
194 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
195 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
196
197 Applies to managed windows (wxFrame and wxDialog classes) only.
198
199 {\it Note} that calling Close does not guarantee that the window will be destroyed; but it
200 provides a way to simulate a manual close of a window, which may or may not be implemented by
201 destroying the window. The default implementation of wxDialog::OnCloseWindow does not
202 necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
203 itself only hides the dialog.
204
205 To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead.

215
216 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
217
218 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
219
220 Converts a point or size from dialog units to pixels.
221
222 For the x dimension, the dialog units are multiplied by the average character width
223 and then divided by 4.
224
225 For the y dimension, the dialog units are multiplied by the average character height
226 and then divided by 8.
227
228 \wxheading{Remarks}
229
230 Dialog units are used for maintaining a dialog's proportions even if the font changes.
231 Dialogs created using Dialog Editor optionally use dialog units.
232
233 You can also use these functions programmatically. A convenience macro is defined:
234
235 {\small
236 \begin{verbatim}
237 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
238 \end{verbatim}

267
268 Converts a point or size from pixels to dialog units.
269
270 For the x dimension, the pixels are multiplied by 4 and then divided by the average
271 character width.
272
273 For the y dimension, the pixels are multipled by 8 and then divided by the average
274 character height.
275

297
298 Destroys the window safely. Use this function instead of the delete operator, since
299 different window classes can be destroyed differently. Frames and dialogs
300 are not destroyed immediately when this function is called - they are added
301 to a list of windows to be deleted on idle time, when all the window's events
302 have been processed. This prevents problems with events being sent to non-existant
303 windows.
304
305 \wxheading{Return value}
306
307 TRUE if the window has either been successfully deleted, or it has been added

565
566 The interpretation of this function differs from class to class.
567 For frames and dialogs, the value returned is the title. For buttons or static text controls, it is
568 the button text. This function can be useful for meta-programs (such as testing
569 tools or special-needs access programs) which need to identify windows
570 by name.

890 This member function is called in response to a keypress. To intercept this event,

921 \wxheading{Remarks}
922
923 This member function is called in response to a keypress, if the window is active. To intercept this event,
924 use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
925 keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
926
927 An example of using this function is in the implementation of escape-character processing for wxDialog,
928 where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
929
930 Note that the ASCII values do not have explicit key codes: they are passed as ASCII
931 values.

971
972 {\bf Note:} This is an obsolete function.

992
993 This is an event handler function called when the user has tried to close a a frame
994 or dialog box using the window manager (X) or system menu (Windows). It is
995 called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
996 that the application can also invoke the handler programmatically.
997
998 Use the EVT\_CLOSE event table macro to handle close events.
999
1000 You should check whether the application is forcing the deletion of the window
1001 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1002 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1003 If not, it is up to you whether you respond by destroying the window.
1004
1005 (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1006 the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1007 it is not possible to skip window deletion.)
1008
1009 If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1010 let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1011 to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1012
1013 \wxheading{Remarks}
1014
1015 The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1016 for backward compatibility with earlier versions of wxWindows. The
1017 default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1018 destroying the window if it returns TRUE or if the close is being forced.

1212 pressed.
1213
1214 \wxheading{Parameters}

1288
1289 Sent to the event handler when the window must be refreshed.
1290
1291 \wxheading{Parameters}
1292
1293 \docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
1294
1295 \wxheading{Remarks}
1296
1297 Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1298
1299 In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
1300
1301 For example:
1302
1303 \small{%
1304 \begin{verbatim}
1305 void MyWindow::OnPaint(wxPaintEvent& event)
1306 {
1307 wxPaintDC dc(this);
1308
1309 DrawMyDocument(dc);
1310 }
1311 \end{verbatim}
1312 }%
1313
1314 You can optimize painting by retrieving the rectangles
1315 that have been damaged and only repainting these. The rectangles are in
1316 terms of the client area, and are unscrolled, so you will need to do
1317 some calculations using the current view position to obtain logical,
1318 scrolled units.
1319
1320 Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
1321
1322 {\small%
1323 \begin{verbatim}
1324 // Called when window needs to be repainted.
1325 void MyWindow::OnPaint(wxPaintEvent& event)
1326 {
1327 wxPaintDC dc(this);
1328
1329 // Find Out where the window is scrolled to
1330 int vbX,vbY; // Top left corner of client
1331 ViewStart(&vbX,&vbY);
1332
1333 int vX,vY,vW,vH; // Dimensions of client area in pixels
1334 wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
1335
1336 while (upd)
1337 {
1338 vX = upd.GetX();
1339 vY = upd.GetY();
1340 vW = upd.GetW();
1341 vH = upd.GetH();
1342
1343 // Alternatively we can do this:
1344 // wxRect rect;
1345 // upd.GetRect(&rect);
1346
1347 // Repaint this rectangle
1348 ...some code...
1349
1350 upd ++ ;
1351 }
1352 }

1500 \wxheading{Remarks}
1501
1502 An event handler is an object that is capable of processing the events
1503 sent to a window. By default, the window is its own event handler, but
1504 an application may wish to substitute another, for example to allow
1505 central implementation of event-handling for a variety of different
1506 window classes.
1507
1508 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1509 an application to set up a chain of event handlers, where an event not handled by one event handler is
1510 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
1511 remove the event handler.

1713
1714 \docparam{handler}{Specifies the handler to be set.}
1715
1716 \wxheading{Remarks}
1717
1718 An event handler is an object that is capable of processing the events
1719 sent to a window. By default, the window is its own event handler, but
1720 an application may wish to substitute another, for example to allow
1721 central implementation of event-handling for a variety of different
1722 window classes.
1723
1724 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
1725 this sets up a chain of event handlers, where an event not handled by one event handler is
1726 handed to the next one in the chain.

1890 Let's say you wish to display 50 lines of text, using the same font.
1891 The window is sized so that you can only see 16 lines at a time.
1892
1893 You would use:
1894
1895 {\small%
1896 \begin{verbatim}
1897 SetScrollbar(wxVERTICAL, 0, 16, 50);
1898 \end{verbatim}
1899 }
1900
1901 Note that with the window at this size, the thumb position can never go
1902 above 50 minus 16, or 34.
1903
1904 You can determine how many lines are currently visible by dividing the current view
1905 size by the character height in pixels.
1906
1907 When defining your own scrollbar behaviour, you will always need to recalculate
1908 the scrollbar settings when the window size changes. You could therefore put your
1909 scrollbar calculations and SetScrollbar
1910 call into a function named AdjustScrollbars, which can be called initially and also
1911 from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

1932
1933 \wxheading{Remarks}
1934
1935 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
1936 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
1937 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
1938 value has to be adjusted when the window is resized, since the page size will have changed.
1939
1940 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
1941 the thumb changes size to reflect the page size relative to the length of the document. When the
1942 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
1943 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
1944 disappear.
1945
1946 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
1947 handling of pages and ranges.

2000 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2001 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2002 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2003 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2004 and usually the scrollbar will be automatically hidden.
