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.
103
104 \wxheading{Parameters}
105
106 \docparam{child}{Child window to add.}
107
108 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
109
110 \func{virtual void}{CaptureMouse}{\void}
111
112 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
113 release the capture.

122
123 A synonym for \helpref{Centre}{wxwindowcentre}.
124
125 \membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent}
126
127 \func{void}{CenterOnParent}{\param{int}{ direction}}
128
129 A synonym for \helpref{CentreOnParent}{wxwindowcentreonparent}.
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 wxCENTER\_FRAME} flag if you want to center the window
141 on its parent and not on the screen (actually, this flag is added automatically for all controls
142 because it makes no sense to center them on the screen)}
143
144 \wxheading{Remarks}
145
146 The actual behaviour depends on the derived window. For a frame or dialog box,
147 centring is relative to the whole display. For a panel item, centring is
148 relative to the panel.

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

181 cause an erase background event to be generated.
182
183 \membersection{wxWindow::ClientToScreen}
184
185 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
186
187 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
188
189 Converts to screen coordinates from coordinates relative to this window.
190
191 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
192 a screen coordinate will be passed out.}
193
194 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
195 a screen coordinate will be passed out.}
196
197 \docparam{pt}{The client position for the second form of the function.}

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

247
248 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
249
250 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
251
252 Converts a point or size from dialog units to pixels.
253
254 For the x dimension, the dialog units are multiplied by the average character width
255 and then divided by 4.
256
257 For the y dimension, the dialog units are multiplied by the average character height
258 and then divided by 8.
259
260 \wxheading{Remarks}
261
262 Dialog units are used for maintaining a dialog's proportions even if the font changes.
263 Dialogs created using Dialog Editor optionally use dialog units.
264
265 You can also use these functions programmatically. A convenience macro is defined:
266
267 {\small
268 \begin{verbatim}
269 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
270 \end{verbatim}

300 Converts a point or size from pixels to dialog units.
301
302 For the x dimension, the pixels are multiplied by 4 and then divided by the average
303 character width.
304
305 For the y dimension, the pixels are multipled by 8 and then divided by the average
306 character height.

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

924
925 Note that not all keypresses can be intercepted this way. If you wish to intercept modifier

948
949 \wxheading{Remarks}
950
951 This member function is called in response to a keypress, if the window is active. To intercept this event,
952 use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
953 keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
954
955 An example of using this function is in the implementation of escape-character processing for wxDialog,
956 where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
957
958 Note that the ASCII values do not have explicit key codes: they are passed as ASCII
959 values.
960
961 This function is only relevant to top-level windows (frames and dialogs), and under
962 Windows only. Under GTK the normal EVT\_CHAR\_ event has the functionality, i.e.
963 you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip}
964 the window won't get the event.

1001
1002 {\bf Note:} This is an obsolete function.

1022
1023 This is an event handler function called when the user has tried to close a a frame
1024 or dialog box using the window manager (X) or system menu (Windows). It is
1025 called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1026 that the application can also invoke the handler programmatically.
1027
1028 Use the EVT\_CLOSE event table macro to handle close events.
1029
1030 You should check whether the application is forcing the deletion of the window
1031 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1032 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1033 If not, it is up to you whether you respond by destroying the window.
1034
1035 (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1036 the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1037 it is not possible to skip window deletion.)
1038
1039 If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1040 let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1041 to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1042
1043 \wxheading{Remarks}
1044
1045 The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1046 for backward compatibility with earlier versions of wxWindows. The
1047 default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1048 destroying the window if it returns TRUE or if the close is being forced.

1149 This member function is called in response to a key up event. To intercept this event,
1150 use the EVT\_KEY\_UP macro in an event table definition. Your {\bf OnKeyUp} handler may call this
1151 default function to achieve default keypress functionality.
1152
1153 Note that not all keypresses can be intercepted this way. If you wish to intercept special
1154 keys, such as shift, control, and function keys, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
1155 \helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.
1156
1157 Most, but not all, windows allow key up events to be intercepted.

1322
1323 \wxheading{Parameters}
1324
1325 \docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
1326
1327 \wxheading{Remarks}
1328
1329 Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1330
1331 In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
1332
1333 For example:
1334
1335 \small{%
1336 \begin{verbatim}
1337 void MyWindow::OnPaint(wxPaintEvent& event)
1338 {
1339 wxPaintDC dc(this);
1340
1341 DrawMyDocument(dc);
1342 }
1343 \end{verbatim}
1344 }%
1345
1346 You can optimize painting by retrieving the rectangles
1347 that have been damaged and only repainting these. The rectangles are in
1348 terms of the client area, and are unscrolled, so you will need to do
1349 some calculations using the current view position to obtain logical,
1350 scrolled units.
1351
1352 Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
1353
1354 {\small%
1355 \begin{verbatim}
1356 // Called when window needs to be repainted.
1357 void MyWindow::OnPaint(wxPaintEvent& event)
1358 {
1359 wxPaintDC dc(this);
1360
1361 // Find Out where the window is scrolled to
1362 int vbX,vbY; // Top left corner of client
1363 ViewStart(&vbX,&vbY);
1364
1365 int vX,vY,vW,vH; // Dimensions of client area in pixels
1366 wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
1367
1368 while (upd)
1369 {
1370 vX = upd.GetX();
1371 vY = upd.GetY();
1372 vW = upd.GetW();
1373 vH = upd.GetH();
1374
1375 // Alternatively we can do this:
1376 // wxRect rect;
1377 // upd.GetRect(&rect);
1378
1379 // Repaint this rectangle
1380 ...some code...
1381
1382 upd ++ ;
1383 }
1384 }

1535 \wxheading{Remarks}
1536
1537 An event handler is an object that is capable of processing the events
1538 sent to a window. By default, the window is its own event handler, but
1539 an application may wish to substitute another, for example to allow
1540 central implementation of event-handling for a variety of different
1541 window classes.
1542
1543 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1544 an application to set up a chain of event handlers, where an event not handled by one event handler is
1545 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
1546 remove the event handler.

1681
1682 \docparam{colour}{The colour to be used as the background colour.}
1683
1684 \wxheading{Remarks}
1685
1686 The background colour is usually painted by the default\rtfsp
1687 \helpref{wxWindow::OnEraseBackground}{wxwindowonerasebackground} event handler function
1688 under Windows and automatically under GTK.
1689
1690 Note that setting the background colour does not cause an immediate refresh, so you
1691 may wish to call \helpref{wxWindow::Clear}{wxwindowclear} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
1692 calling this function.

1712
1713 This sets the size of the window client area in pixels. Using this function to size a window
1714 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
1715 worry about what dimensions the border or title bar have when trying to fit the window
1716 around panel items, for example.

1757
1758 \docparam{handler}{Specifies the handler to be set.}
1759
1760 \wxheading{Remarks}
1761
1762 An event handler is an object that is capable of processing the events
1763 sent to a window. By default, the window is its own event handler, but
1764 an application may wish to substitute another, for example to allow
1765 central implementation of event-handling for a variety of different
1766 window classes.
1767
1768 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
1769 this sets up a chain of event handlers, where an event not handled by one event handler is
1770 handed to the next one in the chain.

1918 Let's say you wish to display 50 lines of text, using the same font.
1919 The window is sized so that you can only see 16 lines at a time.
1920
1921 You would use:
1922
1923 {\small%
1924 \begin{verbatim}
1925 SetScrollbar(wxVERTICAL, 0, 16, 50);
1926 \end{verbatim}
1927 }
1928
1929 Note that with the window at this size, the thumb position can never go
1930 above 50 minus 16, or 34.
1931
1932 You can determine how many lines are currently visible by dividing the current view
1933 size by the character height in pixels.
1934
1935 When defining your own scrollbar behaviour, you will always need to recalculate
1936 the scrollbar settings when the window size changes. You could therefore put your
1937 scrollbar calculations and SetScrollbar
1938 call into a function named AdjustScrollbars, which can be called initially and also
1939 from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

1959 \docparam{refresh}{TRUE to redraw the scrollbar, FALSE otherwise.}
1960
1961 \wxheading{Remarks}
1962
1963 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
1964 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
1965 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
1966 value has to be adjusted when the window is resized, since the page size will have changed.
1967
1968 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
1969 the thumb changes size to reflect the page size relative to the length of the document. When the
1970 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
1971 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
1972 disappear.
1973
1974 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
1975 handling of pages and ranges.

2027
2028 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2029 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2030 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2031 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2032 and usually the scrollbar will be automatically hidden.
