I have 4 ListBoxes in my GUI created through App Designer.
I need to populate Listbox_2 according to which item in ListBox_1 has been selected.
Basically I need an event "Item_Selected" ad relative callback that does not seem to ba available for the ListBox.
The only cllback available is "ValueChanged". Is such an event triggered when an item is selected?
How can I generate such an evet myself?
Thank you very much
