[ltk-user] Add an event in the ltk event queue
by Syll 05 Jun '12

05 Jun '12

Hello Is it possible to add an event in the ltk event queue from another thread ? I can put events in a queue and use (after ...) to read it periodically in the ltk thread, but it would be easier and more efficient to use the ltk event queue directly. Thank you Syll

[ltk-user] Selection in listbox
by Syll 28 Apr '12

28 Apr '12

Hello I have a few problems/questions with listbox selection (especially multiple selection). * If the listbox does'nt have the focus and I select items with Ctrl+click (including the first one), events from keys are not triggered for this listbox. Is it because the listbox has'nt get the focus at all ? How do i give the focus to the listbox (but not to any item) ? * If I understand this well, there are two special states that can be applied to list items : say "selected" (zero, one or several items) and "focused" (zero or one item). * I can select an item with listbox-select. How can I give the focus to an item ? * I catch selection events with <<ListboxSelect>>. How can I catch "item focus" events ? How can I get the focused item ? Thank you Syll
