Get all selected options from listbox embedded into input dialog

[georgtree]

Hello!
I faced with the issue - I can't get all selected listbox elements from the input dialog by method [dlg valueInput], it returns only first selected element from the top, even if the -selectmode multiple is set for that widget. How to get values in form of list of all currently selected elements?
Thank you in advance!

The same issue is with tbl (tablelist) widget, used in the same manner. IIRC, the general solution was involved, but obviously not for the input dialog. I'll try and solve this.

Thanks for the feedback.

Well, for listbox and probably for tablelist I'd use the following method:
along with -selectmode multiple I'd set two other options - popup and -onevent.

Though, the popup is optional, it's a command launched when a user tries to call a context menu on the listbox.

The main for this issue is the -onevent option that is a binding list of event handler event handler ... pairs to handle events on a widget, where handlers are commands that may include Tk wildcards of bind command, the main is %W, the widget's path.

Briefly, try this template of listbox options:

-selectmode multiple -popup {::NS::LbxPopup %X %Y} -onevent {<<ListboxSelect>> {puts "%W : \[%W curselection\]"}}

Instead of the "puts", set your command that saves the current selection ([%W curselection]) to a variable, for the final processing it when a user selects Ok or a similar confirmation.

Personally, I use the input dialogue for rather simple cases, i.e. when I should simply get some data ordered in rows. It's not designed for a complex dialogue. But in e_menu application and alike, it's just what's needed.

It would be good to make a set of ready to use apave dialogues' templates in alited's Tools/Paver menu. Though, you don't use alited anymore alas.
