|
|
This class provides an interface to selecting from the predefined
|
|
options or entering custom string.
|
|
|
|
The typical usage should be:
|
|
type_sel = StandardCustomSelector(mapping,None,custom_key,active_key)
|
|
whatever_table.attach(type_sel,...)
|
|
or
|
|
type_sel = StandardCustomSelector(mapping,cbe,custom_key,active_key)
|
|
with the existing ComboBoxEntry cbe.
|
|
|
|
To set up the combo box, specify the active key at creation time,
|
|
or later (or with custom text) use:
|
|
type_sel.set_values(i,s)
|
|
|
|
and later, when or before the dialog is closed, do:
|
|
(i,s) = type_sel.get_values()
|
|
|
|
to obtain the tuple of (int,str) corresponding to the user selection.
|
|
|
|
No selection will return (custom_key,'') if the custom key is given,
|
|
or (None,'') if it is not given.
|
|
|
|
The active_key determines the default selection that will be displayed
|
|
upon widget creation. If omitted, the entry will be empty. If present,
|
|
then no selection on the user's part will return the
|
|
(active_key,mapping[active_key]) tuple.
