in thread Tkx g_bind to menu on listbox only for selected row

Thanks! That worked for me!

Final question: The menu persists after the user has moved the mouse away from the selected row. There does not seem to be anything like "g_tk___popdown()". How can I pop down the menu?

    There does not seem to be anything like "g_tk___popdown()". How can I pop down the menu?

    You can't, that is the point/purpose/design behind tk_popup, it shows a menu, pauses your program, until user makes a selection (or escapes)

    maybe you want balloons/tooltips ?

      No good for me, as I need to call subs from the user's selection. Frustrating, as all the available documentation I've seen refers to 'the OSs native functions' for popping the menu down. I really don't want the user to have to remember to press 'Esc' to get rid of the menu!

      Windows manages to do this with its own apps, why can't Perl?

      Thanks a lot for all your help anyway!!! I've got it semi-working now but will leave it turned off by default, activatable by user option as an experiment until I find something better.

        No good for me, ...

        Well, that is what you get with tk+listbox+optionmenu,

        Tkx is 98% tcl/tk, so whatever choices those tcl guys made is what you have

        If you want different behaviour, you'll have to pick a different widget, or copy menu.tcl and edit out the grabs (and whatever else) until it does what you want

        Good luck
