time-selector: fix tabbing focus from hours to minute
Fix tabbing in GcalEditDialog
.
GcalEditDialog
was setting can_focus=True
on GcalTimeSelector
objects,
which prevented the children (the input fields) from obtaining the focus.
Fixed by simply not specifying can_focus=True
(it takes the default
value of False
). This also means that we can now tab from the date field
to the hours field.
