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.

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

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144 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer.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.

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}.

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.}

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}

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.

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

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

922
923 Note that the ASCII values do not have explicit key codes: they are passed as ASCII

925
926 Note that not all keypresses can be intercepted this way. If you wish to intercept modifier
927 keypresses, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or

949
950 \wxheading{Remarks}
951
952 This member function is called in response to a keypress, if the window is active. To intercept this event,
953 use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
954 keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
955
956 An example of using this function is in the implementation of escape-character processing for wxDialog,
957 where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
958
959 Note that the ASCII values do not have explicit key codes: they are passed as ASCII
960 values.
961
962 This function is only relevant to top-level windows (frames and dialogs), and under
963 Windows only. Under GTK the normal EVT\_CHAR\_ event has the functionality, i.e.
964 you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip}
965 the window won't get the event.

1002
1003 {\bf Note:} This is an obsolete function.

1023
1024 This is an event handler function called when the user has tried to close a a frame
1025 or dialog box using the window manager (X) or system menu (Windows). It is
1026 called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1027 that the application can also invoke the handler programmatically.
1028
1029 Use the EVT\_CLOSE event table macro to handle close events.
1030
1031 You should check whether the application is forcing the deletion of the window
1032 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1033 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1034 If not, it is up to you whether you respond by destroying the window.
1035
1036 (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1037 the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1038 it is not possible to skip window deletion.)
1039
1040 If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1041 let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1042 to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1043
1044 \wxheading{Remarks}
1045
1046 The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1047 for backward compatibility with earlier versions of wxWindows. The
1048 default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1049 destroying the window if it returns TRUE or if the close is being forced.

1150 This member function is called in response to a key up event. To intercept this event,
1151 use the EVT\_KEY\_UP macro in an event table definition. Your {\bf OnKeyUp} handler may call this
1152 default function to achieve default keypress functionality.
1153
1154 Note that not all keypresses can be intercepted this way. If you wish to intercept special
1155 keys, such as shift, control, and function keys, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
1156 \helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.
1157
1158 Most, but not all, windows allow key up events to be intercepted.

1323
1324 \wxheading{Parameters}
1325
1326 \docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
1327
1328 \wxheading{Remarks}
1329
1330 Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1331
1332 In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
1333
1334 For example:
1335
1336 \small{%
1337 \begin{verbatim}
1338 void MyWindow::OnPaint(wxPaintEvent& event)
1339 {
1340 wxPaintDC dc(this);
1341
1342 DrawMyDocument(dc);
1343 }
1344 \end{verbatim}
1345 }%
1346
1347 You can optimize painting by retrieving the rectangles
1348 that have been damaged and only repainting these. The rectangles are in
1349 terms of the client area, and are unscrolled, so you will need to do
1350 some calculations using the current view position to obtain logical,
1351 scrolled units.
1352
1353 Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
1354
1355 {\small%
1356 \begin{verbatim}
1357 // Called when window needs to be repainted.
1358 void MyWindow::OnPaint(wxPaintEvent& event)
1359 {
1360 wxPaintDC dc(this);
1361
1362 // Find Out where the window is scrolled to
1363 int vbX,vbY; // Top left corner of client
1364 ViewStart(&vbX,&vbY);
1365
1366 int vX,vY,vW,vH; // Dimensions of client area in pixels
1367 wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
1368
1369 while (upd)
1370 {
1371 vX = upd.GetX();
1372 vY = upd.GetY();
1373 vW = upd.GetW();
1374 vH = upd.GetH();
1375
1376 // Alternatively we can do this:
1377 // wxRect rect;
1378 // upd.GetRect(&rect);
1379
1380 // Repaint this rectangle
1381 ...some code...
1382
1383 upd ++ ;
1384 }
1385 }

1547 An event handler is an object that is capable of processing the events
1548 sent to a window. By default, the window is its own event handler, but
1549 an application may wish to substitute another, for example to allow
1550 central implementation of event-handling for a variety of different
1551 window classes.
1552
1553 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1554 an application to set up a chain of event handlers, where an event not handled by one event handler is
1555 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

1703 \wxheading{Parameters}
1704
1705 \docparam{colour}{The colour to be used as the background colour.}
1706
1707 \wxheading{Remarks}
1708
1709 The background colour is usually painted by the default\rtfsp
1710 \helpref{wxWindow::OnEraseBackground}{wxwindowonerasebackground} event handler function
1711 under Windows and automatically under GTK.
1712
1713 Note that setting the background colour does not cause an immediate refresh, so you
1714 may wish to call \helpref{wxWindow::Clear}{wxwindowclear} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
1715 calling this function.
1716
1717 Note that when using this functions under GTK, you will disable the so called "themes",

1735
1736 This sets the size of the window client area in pixels. Using this function to size a window
1737 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
1738 worry about what dimensions the border or title bar have when trying to fit the window
1739 around panel items, for example.

1780
1781 \docparam{handler}{Specifies the handler to be set.}
1782
1783 \wxheading{Remarks}
1784
1785 An event handler is an object that is capable of processing the events
1786 sent to a window. By default, the window is its own event handler, but
1787 an application may wish to substitute another, for example to allow
1788 central implementation of event-handling for a variety of different
1789 window classes.
1790
1791 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
1792 this sets up a chain of event handlers, where an event not handled by one event handler is
1793 handed to the next one in the chain.

1941 Let's say you wish to display 50 lines of text, using the same font.
1942 The window is sized so that you can only see 16 lines at a time.
1943
1944 You would use:
1945
1946 {\small%
1947 \begin{verbatim}
1948 SetScrollbar(wxVERTICAL, 0, 16, 50);
1949 \end{verbatim}
1950 }
1951
1952 Note that with the window at this size, the thumb position can never go
1953 above 50 minus 16, or 34.
1954
1955 You can determine how many lines are currently visible by dividing the current view
1956 size by the character height in pixels.
1957
1958 When defining your own scrollbar behaviour, you will always need to recalculate
1959 the scrollbar settings when the window size changes. You could therefore put your
1960 scrollbar calculations and SetScrollbar
1961 call into a function named AdjustScrollbars, which can be called initially and also
1962 from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

1982 \docparam{refresh}{TRUE to redraw the scrollbar, FALSE otherwise.}
1983
1984 \wxheading{Remarks}
1985
1986 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
1987 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
1988 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
1989 value has to be adjusted when the window is resized, since the page size will have changed.
1990
1991 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
1992 the thumb changes size to reflect the page size relative to the length of the document. When the
1993 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
1994 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
1995 disappear.
1996
1997 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
1998 handling of pages and ranges.

2050
2051 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2052 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2053 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2054 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2055 and usually the scrollbar will be automatically hidden.
