Thanks for your answer here Mattias -
GetActiveWindow does seem to be just what I need to be able to create my
own code from - but I cant get it to work :(
I have extracted the function and placed in a new app - causes exception
at gtk_is_window
Are Gtk windows the same as Gdk windows ? - 'get_toplevels' returns
gdkwindows, but using as gtkwindow ?
uses gtk2, glib, gdk;
function GetActiveWindow :integer;
var
TopList, List: PGList;
Widget: PGTKWidget;
Window: PGTKWindow;
begin
Result := 0;
TopList := glib.pglist(gdk_window_get_toplevels);
List := TopList;
while List <> nil do begin
if (List^.Data <> nil) then begin
gdk_window_get_user_data(PGDKWindow(List^.Data), Pgpointer(@Window));
// --------FAILS AT NEXT LINE //
if gtk_is_window(Window) then begin
Widget := Window^.focus_widget;
if Widget=nil then Widget:=PGtkWidget(Window);
if (Widget <> nil) and gtk_widget_has_focus(Widget) then begin
Result := 1;//PtrUInt(GetMainWidget(PGtkWidget(Window)));
Break;
end;
end;
end;
list := g_list_next(list);
end;
if TopList <> nil then g_list_free(TopList);
end;
