It definitely makes sense for an on-screen window to have a transient dialog. With a little care (see "messages boxes" in the widget demo) on the mac the transient can be a "sheet" that opens from the top of the master window. It even makes sense for an iconified window to have a transient since the window manager still controls iconified windows. But a withdrawn window, with no icon (and no listing in the mac Window menu) is beyond the user's control. The really deadly combination is when a transient of a withdrawn window (so the transient is withdrawn) also has a grab on mouse and keyboard events. That one should be avoided. It is not clear to me why Tk allows it. I believe it should be avoided on all platforms, since withdrawn windows are supposed to be completely removed from the window manager and only known to Tk. But testing is needed, of course. I don't know the full history. I know there were changes between 8.6.9 and 8.6.10 needed to bring the mac port to its current state where it passes all of the Tk regression tests. (That is not the case with unix at the moment and I know there are many issues with iconified and withdrawn windows in Gnome 3 due to changes in window manager behavior which have not been fully incorporated into Tk.) I suspect there were many prior releases with no changes to this behavior on the mac. PS The formerly soon-to-be-released 8.6.10 has now been released. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38882> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
