407 | Close calls the <A HREF="wx45.htm#wxcloseevent">close handler</A> for the window, providing an opportunity for the window to | |
408 | choose whether to destroy the window.<P> | |
409 | The close handler should check whether the window is being deleted forcibly, | |
410 | using <A HREF="wx45.htm#wxcloseeventgetforce">wxCloseEvent::GetForce</A>, in which case it should | |
411 | destroy the window using <A HREF="wx260.htm#wxwindowdestroy">wxWindow::Destroy</A>.<P> | |
412 | Applies to managed windows (wxFrame and wxDialog classes) only.<P> | |
413 | <I>Note</I> that calling Close does not guarantee that the window will be destroyed; but it | |
414 | provides a way to simulate a manual close of a window, which may or may not be implemented by | |
415 | destroying the window. The default implementation of wxDialog::OnCloseWindow does not | |
416 | necessarily delete the dialog, since it will simply simulate an wxID_CANCEL event which | |
417 | itself only hides the dialog.<P> | |
418 | To guarantee that the window will be destroyed, call <A HREF="wx260.htm#wxwindowdestroy">wxWindow::Destroy</A> instead.<P> | |

1361 | This is an event handler function called when the user has tried to close a a frame | |
1362 | or dialog box using the window manager (X) or system menu (Windows). It is | |

1366 | You should check whether the application is forcing the deletion of the window | |
1367 | using <A HREF="wx45.htm#wxcloseeventgetforce">wxCloseEvent::GetForce</A>. If this is TRUE, | |

1371 | the window is required, test for the negative of CanVeto. If CanVeto returns FALSE, | |
1372 | it is not possible to skip window deletion.)<P> | |
1373 | If you don't destroy the window, you should call <A HREF="wx45.htm#wxcloseeventveto">wxCloseEvent::Veto</A> to | |
1374 | let the calling code know that you did not destroy the window. This allows the <A HREF="wx260.htm#wxwindowclose">wxWindow::Close</A> function | |

1603 | </FONT>You can optimize painting by retrieving the rectangles | |
1604 | that have been damaged and only repainting these. The rectangles are in | |
