Toga Selection widget

[montyonthebonty]

Good evening

Is there a way of adding a second, hidden, field to an item in a selection widget, like a primary key?

Thanks
Chris

The best option I can give you right now is to construct your data as a dictionary:

data = {
    'label 1': 15,
    'label 2': 16,
    'label 3': 17,
}

Then pass that data to the selection widget as the data. When the item is selected, you'll get back the label; use that to look up the primary key in the data.

Longer term, the intention is to allow you to pass any object with a __str__ to the selection, so you can associate the primary key directly with the selected item. We also want to allow the use of "ListSource" objects, similar to how a Table view works, so that the data can be completely abstracted from the widget.

Thanks, that’s great - although it’s good to hear there’s a longer term solution in the pipeline as well, just in case somebody manages to use the same label twice in the source table!
