Creating themed/style widget question

[Adrian Davis]

I'd like to create a themed/style widget, looking exactly like the ttk
combobox, which pops-up a frame/toplevel instead of a listbox.

Is it possible to script this?

If so, are there and examples which illustrate this?

Many Thanks,

Something which is always possible for widget where only the initial
appearance counts, is to bind <ButtonPress-1> with code that ends with
"break".
This way, the default binding is disabled and nothing pops up. You can
post your toplevel/frame at that spot, and set a local grab to detect
clicks outside and unpost it (just like the combobox does internally).

That seems to do exactly what I want!!

The Ttk combobox is itself scripted in Tcl -- check the lib/tk8.x/ttk
folder of your Tcl installation for combobox.tcl. You can see the
bindings that need to be overridden at the top. You can also see that
this code already creates a toplevel and frame to hold the listbox and
scrollbar, so you can probably just copy+paste the relevant bits and
then create a new binding class, then ttk::combobox .cb -class MyCombo.
