Focus all widgets in Columns about urwid HOT 7 CLOSED

@rndUser I think we need to add the hash method to AttrSpec for that to work. It certainly works with palettes:

from urwid import MainLoop, Edit, AttrMap, Columns, ListBox, SimpleListWalker

loop = MainLoop(
    widget=ListBox(SimpleListWalker([
        AttrMap(
            Columns([
                AttrMap(Edit('one'), 'col1'),
                AttrMap(Edit('two'), 'col2')]),
            None,
            focus_map={'col1': 'focus1', 'col2': 'focus2'}),
        AttrMap(
            Columns([
                AttrMap(Edit('three'), 'col1'),
                AttrMap(Edit('four'), 'col2')]),
            None,
            focus_map={'col1': 'focus1', 'col2': 'focus2'})])),
    palette=[
        ('col1', 'dark green', 'light gray'),
        ('col2', 'dark blue', 'light gray'),
        ('focus1', 'light green', 'dark blue'),
        ('focus2', 'light blue', 'dark blue')])
loop.run()

@rndusr if you would like the whole Columns to be visibly in focus put an AttrMap around the Columns instead of inside it.

Closing this issue for now, please feel free to reopen if this doesn't solve your problem.

I want different colors for each widget in the Columns, so wrapping the whole Columns in an AttrMap doesn't work.

I can't figure out how to reopen this issue. Am I too dumb or simply not allowed?

You can have AttrMap around the Columns and inside each item too. The AttrMap outside just needs to have a focus_map passed as a dict so it can modify attributes already set by the widgets inside.

Ok, I don't quite understand how this might work right now, but I'm gonna bang my head against the manual a bit more. Thanks for your quick help!

But I have one more question: I'm currently passing AttrSpecs to AttrMap like this:

AttrMap(somewidget, AttrSpec('brown', 'black'), AttrSpec('yellow', 'dark gray'))

Can I keep doing this when I pass dicts to AttrMap or will I have to use a palette? Or, to ask in another way: Can I use AttrSpecs as key and value in the dict I'm passing as focus_map?

I guess I'll have to do some rewriting then.
Thanks again for your help. It's very much appreciated.
