Double click with a listbox

[Cecil Westerhof]

I had:
bind .f.brew <<ListboxSelect>> [list makeTea %W]

That worked fine, but I prefer not to fire on selection of an entry,
but when an entry is double-clicked. So I tried (beside some other
things):
bind .f.brew <<Double-1>> [list makeTea %W]

But that does not work. How would I get that working?

It needs to be:

bind .f.brew <Double-1> [list makeTea %W]

One set of <Angle Brackets> is used for "real" bindings - ones that refer to actual mouse or keyboard actions.

When <<Two Sets>> are used, it's for a "virtual" event binding, where you have a binding with a custom name and can then assign any number of "real" bindings to trigger it with the [event] command. (For instance, the [text] widget binds to the virtual <<Copy>> and <<Paste>> events, and these are triggered by <Control-c> & <Insert>, and <Control-v> & <Shift-Insert>, respectively.)
