…UI event notification when the selected file type filter changes Added method wxFileDialog::GetCurrentlySelectedFilterIndex(). This method returns the 0-based file type filter currently selected in a file dialog, analogously to GetCurrentlySelectedFilename() does for the current file. Only supported in MSW. The value returned is always undefined elsewhere. Added a wxEVT_UPDATE_UI event notification when the selection of the file type filter changes. This allows extra file dialog controls to adjust their state depending on the file type filter currently selected. Only supported in MSW.

@vadz hDlg causes a warning because it is not used. Could you add WXUNUSED?
