I have a big table with buttons, entries and labels,
and would make the TAB key jump to next entry instead
of going through every widget. The set_focus_chain()
seems to exist for this purpose, but I couldn't make
it work.
Below is the full source code for a simple window with
a 2x2 table containing :
Entry1 Button1
Entry2 Button2
The set_focus_chain() runs with a list containing {
Entry1, Entry2 } but doesn't modify TAB key behaviour.
Any hint?
Regards,
Romain
