Pressing "Esc" key closed the dialog with only wxID_OK button (but no wxID_CANCEL one) by default but pressing the "close window" button only closed it if wxID_CANCEL was present. Fix this by using the same code in OnCloseWindow() as in OnCharHook(), after extracting it into the new SendCloseButtonClickEvent() method. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65488 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
