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. | |

154 | \func{void}{Centre}{\param{int}{ direction = wxBOTH}} | |
155 | ||
156 | Centres the window. | |

159 | ||
160 | \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp | |
161 | or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag | |
162 | if you want to center the window on the entire screen and not on its | |

164 | ||
165 | The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer | |

189 | \wxheading{Remarks} | |
190 | ||
191 | This methods provides for a way to center top level windows over their | |
192 | parents instead of the entire screen. If there is no parent or if the | |
193 | window is not a top level window, then behaviour is the same as | |

250 | \membersection{wxWindow::Close}\label{wxwindowclose} | |
251 | ||
252 | \func{virtual bool}{Close}{\param{bool}{ force = FALSE}} | |
253 | ||
254 | The purpose of this call is to provide a safer way of destroying a window than using | |
255 | the {\it delete} operator. | |
256 | ||
257 | \wxheading{Parameters} | |
258 | ||
259 | \docparam{force}{FALSE if the window's close handler should be able to veto the destruction | |
260 | of this window, TRUE if it cannot.} | |
261 | ||
262 | \wxheading{Remarks} | |
263 | ||
264 | Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to | |
265 | choose whether to destroy the window. | |
266 | ||
267 | The close handler should check whether the window is being deleted forcibly, | |
268 | using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should | |
269 | destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}. | |
270 | ||
271 | Applies to managed windows (wxFrame and wxDialog classes) only. | |
272 | ||
273 | {\it Note} that calling Close does not guarantee that the window will be destroyed; but it | |
274 | provides a way to simulate a manual close of a window, which may or may not be implemented by | |
275 | destroying the window. The default implementation of wxDialog::OnCloseWindow does not | |
276 | necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which | |
277 | itself only hides the dialog. | |
278 | ||
279 | To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead. | |

291 | ||
292 | \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}} | |
293 | ||
294 | Converts a point or size from dialog units to pixels. | |
295 | ||
296 | For the x dimension, the dialog units are multiplied by the average character width | |
297 | and then divided by 4. | |
298 | ||
299 | For the y dimension, the dialog units are multiplied by the average character height | |
300 | and then divided by 8. | |
301 | ||
302 | \wxheading{Remarks} | |
303 | ||
304 | Dialog units are used for maintaining a dialog's proportions even if the font changes. | |
305 | Dialogs created using Dialog Editor optionally use dialog units. | |
306 | ||
307 | You can also use these functions programmatically. A convenience macro is defined: | |

1067 | ||
1068 | This member function is called in response to a keypress. To intercept this event, | |
1069 | use the EVT\_CHAR macro in an event table definition. Your {\bf OnChar} handler may call this | |
1070 | default function to achieve default keypress functionality. | |
1071 | ||
1072 | Note that the ASCII values do not have explicit key codes: they are passed as ASCII | |
1073 | values. | |
1074 | ||
1075 | Note that not all keypresses can be intercepted this way. If you wish to intercept modifier | |
1076 | keypresses, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or | |
1077 | \helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}. | |
1078 | ||
1079 | Most, but not all, windows allow keypresses to be intercepted. | |
1080 | ||
1081 | {\bf Tip:} be sure to call {\tt event.Skip()} for events that you don't process in this function, | |

1092 | \func{void}{OnCharHook}{\param{wxKeyEvent\&}{ event}} | |
1093 | ||
1094 | This member is called to allow the window to intercept keyboard events | |
1095 | before they are processed by child windows. | |
1096 | ||
1097 | \wxheading{Parameters} | |

1101 | ||
1102 | \wxheading{Remarks} | |
1103 | ||
1104 | This member function is called in response to a keypress, if the window is active. To intercept this event, | |
1105 | use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular | |
1106 | keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing. | |
1107 | ||
1108 | An example of using this function is in the implementation of escape-character processing for wxDialog, | |
1109 | where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event. | |
1110 | ||
1111 | Note that the ASCII values do not have explicit key codes: they are passed as ASCII | |
1112 | values. | |
1113 | ||
1114 | This function is only relevant to top-level windows (frames and dialogs), and under | |
1115 | Windows only. Under GTK the normal EVT\_CHAR\_ event has the functionality, i.e. | |
1116 | you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip} | |
1117 | the window won't get the event. | |

1151 | ||
1152 | Called when the user has tried to close a a frame | |

1154 | ||
1155 | {\bf Note:} This is an obsolete function. | |

1173 | ||
1174 | \func{void}{OnCloseWindow}{\param{wxCloseEvent\& }{event}} | |
1175 | ||
1176 | This is an event handler function called when the user has tried to close a a frame | |
1177 | or dialog box using the window manager (X) or system menu (Windows). It is | |
1178 | called via the \helpref{wxWindow::Close}{wxwindowclose} function, so | |
1179 | that the application can also invoke the handler programmatically. | |
1180 | ||
1181 | Use the EVT\_CLOSE event table macro to handle close events. | |
1182 | ||
1183 | You should check whether the application is forcing the deletion of the window | |
1184 | using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE, | |
1185 | destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}. | |
1186 | If not, it is up to you whether you respond by destroying the window. | |
1187 | ||
1188 | (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of | |
1189 | the window is required, test for the negative of CanVeto. If CanVeto returns FALSE, | |
1190 | it is not possible to skip window deletion.) | |
1191 | ||
1192 | If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to | |
1193 | let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function | |
1194 | to return TRUE or FALSE depending on whether the close instruction was honoured or not. | |
1195 | ||
1196 | \wxheading{Remarks} | |
1197 | ||
1198 | The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains | |
1199 | for backward compatibility with earlier versions of wxWindows. The | |
1200 | default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose}, | |
1201 | destroying the window if it returns TRUE or if the close is being forced. | |

1248 | ||
1249 | Under non-Windows platforms, this event is simulated (simply generated just before the | |

1251 | you set the text background colour explicitly in order to prevent flicker. | |
1252 | The default background colour under GTK is grey. | |

1409 | You can choose any member function to receive | |

1412 | ||
1413 | The default implementation for \helpref{wxFrame::OnMenuHighlight}{wxframeonmenuhighlight} displays help | |
1414 | text in the first field of the status bar. | |
1415 | ||
1416 | This function was known as {\bf OnMenuSelect} in earlier versions of wxWindows, but this was confusing | |
1417 | since a selection is normally a left-click action. | |

1478 | Sent to the event handler when the window must be refreshed. | |

1482 | \docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.} | |
1483 | ||
1484 | \wxheading{Remarks} | |
1485 | ||
1486 | Use the EVT\_PAINT macro in an event table definition to intercept paint events. | |
1487 | ||
1488 | Note that In a paint event handler, the application must {\it always} create a \helpref{wxPaintDC}{wxpaintdc} object, | |
1489 | even if you do not use it. Otherwise, under MS Windows, refreshing for this and other windows will go wrong. | |
1490 | ||
1491 | For example: | |
1492 | ||
1493 | \small{% | |
1494 | \begin{verbatim} | |
1495 | void MyWindow::OnPaint(wxPaintEvent\& event) | |
1496 | { | |
1497 | wxPaintDC dc(this); | |
1498 | ||
1499 | DrawMyDocument(dc); | |
1500 | } | |
1501 | \end{verbatim} | |
1502 | }% | |
1503 | ||
1504 | You can optimize painting by retrieving the rectangles | |
1505 | that have been damaged and only repainting these. The rectangles are in | |
1506 | terms of the client area, and are unscrolled, so you will need to do | |
1507 | some calculations using the current view position to obtain logical, | |
1508 | scrolled units. | |
1509 | ||
1510 | Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class: | |
1511 | ||
1512 | {\small% | |
1513 | \begin{verbatim} | |
1514 | // Called when window needs to be repainted. | |
1515 | void MyWindow::OnPaint(wxPaintEvent\& event) | |
1516 | { | |
1517 | wxPaintDC dc(this); | |
1518 | ||
1519 | // Find Out where the window is scrolled to | |
1520 | int vbX,vbY; // Top left corner of client | |
1521 | GetViewStart(&vbX,&vbY); | |
1522 | ||
1523 | int vX,vY,vW,vH; // Dimensions of client area in pixels | |
1524 | wxRegionIterator upd(GetUpdateRegion()); // get the update rect list | |
1525 | ||
1526 | while (upd) | |
1527 | { | |
1528 | vX = upd.GetX(); | |
1529 | vY = upd.GetY(); | |
1530 | vW = upd.GetW(); | |
1531 | vH = upd.GetH(); | |
1532 | ||
1533 | // Alternatively we can do this: | |
1534 | // wxRect rect; | |
1535 | // upd.GetRect(&rect); | |
1536 | ||
1537 | // Repaint this rectangle | |
1538 | ...some code... | |

1709 | An event handler is an object that is capable of processing the events | |

1715 | \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows | |

1910 | The background colour is usually painted by the default\rtfsp | |

1912 | under Windows and automatically under GTK. | |
1913 | ||

1942 | ||
1943 | This sets the size of the window client area in pixels. Using this function to size a window | |
1944 | tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not | |

2027 | ||
2028 | \wxheading{Remarks} | |
2029 | ||
2030 | An event handler is an object that is capable of processing the events | |
2031 | sent to a window. By default, the window is its own event handler, but | |
2032 | an application may wish to substitute another, for example to allow | |
2033 | central implementation of event-handling for a variety of different | |
2034 | window classes. | |
2035 | ||
2036 | It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since | |
2037 | this sets up a chain of event handlers, where an event not handled by one event handler is | |

2179 | ||
2180 | Let's say you wish to display 50 lines of text, using the same font. | |
2181 | The window is sized so that you can only see 16 lines at a time. | |
2182 | ||
2183 | You would use: | |
2184 | ||
2185 | {\small% | |
2186 | \begin{verbatim} | |
2187 | SetScrollbar(wxVERTICAL, 0, 16, 50); | |
2188 | \end{verbatim} | |
2189 | } | |
2190 | ||
2191 | Note that with the window at this size, the thumb position can never go | |
2192 | above 50 minus 16, or 34. | |
2193 | ||
2194 | You can determine how many lines are currently visible by dividing the current view | |
2195 | size by the character height in pixels. | |
2196 | ||
2197 | When defining your own scrollbar behaviour, you will always need to recalculate | |
2198 | the scrollbar settings when the window size changes. You could therefore put your | |
2199 | scrollbar calculations and SetScrollbar | |

2221 | \docparam{refresh}{TRUE to redraw the scrollbar, FALSE otherwise.} | |
2222 | ||
2223 | \wxheading{Remarks} | |
2224 | ||
2225 | The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you | |
2226 | click on the area above/left of or below/right of the thumb. Normally you will want a whole visible | |
2227 | page to be scrolled, i.e. the size of the current view (perhaps the window client size). This | |
2228 | value has to be adjusted when the window is resized, since the page size will have changed. | |
2229 | ||
2230 | In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows | |
2231 | the thumb changes size to reflect the page size relative to the length of the document. When the | |
2232 | document size is only slightly bigger than the current view (window) size, almost all of the scrollbar | |
2233 | will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems) | |
2234 | disappear. | |
2235 | ||
2236 | Currently, this function should be called before SetPageRange, because of a quirk in the Windows | |
2237 | handling of pages and ranges. | |

2289 | ||
2290 | The range of a scrollbar is the number of steps that the thumb may travel, rather than the total | |
2291 | object length of the scrollbar. If you are implementing a scrolling window, for example, you | |
2292 | would adjust the scroll range when the window is resized, by subtracting the window view size from the | |
2293 | total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero | |
2294 | and usually the scrollbar will be automatically hidden. | |
