Quick question about Display Attributes. So the idea of
AttrMap is to change one set of attributes to others but this suggests that widgets can own Attributes in the first place. The only widget I see that has this is Text but how does this work for other widgets?

So let's say I have a
Columns container with a bunch of Text widget. I can do a attr = AttrMap(my_column, "some_colour") on the container to change the colour of everything in the column to a colour. At this point does my column have any attributes of itself?
If sometime later I want to change the colour of my columns should I do
attr2 = AttrMap(my_column, "some_other_colour") ? Or call set_attr_map on attr instance?
If its the latter then do I want the new mapping to be
{None: "some_other_colour"} or {"some_colour": "some_other_colour"}
?
t1 = urwid.LineBox(urwid.Text("One"))
t2 = urwid.LineBox(urwid.Text("Two"))
col = urwid.Columns([(10, t1), (10, t2)])
w = urwid.Padding(col, align="center")
fill = urwid.Filler(w, "top")
loop = urwid.MainLoop(fill)
loop.run()
which gives
Explicitly providing
left to Padding does work but can't get it to work automatically with align
Isn't
Padding what I'd want to center-align a Column widget?
and hopefully a simpler question. I want to have a pane where I can watch the output of a shell command into (something like
tail -F log.txt). Isurwid.Terminal` the widget I want or is that an overkill? I only need it to be read-only so I thought I might be able to get away with something simpler
What's the status of
.pack(...) implementation? A contributor made a PR which used it, assuming it worked for many widgets, but apparently it's a work in progress? There doesn't seem to be an urwid issue tracking this, so I wanted to check if this was on the radar for upcoming work or if it had slipped through the net - and if there was an issue in urwid then we'd have something to refer to :+1:
:thumbsup:
although I think that function gets me as far as the container
so I had to also set the
focus_position of the final container as well

Is there a way to make this structure flat? I wanna have a tree for every user (nodes under SEARCH RESULTS). Should I use Pile for that? How would the widget structure look like?
class Browser:
def __init__(self, search_replies):
self.top_node = BrowserParentNode(search_replies, key='SEARCH RESULTS')
self.list_box = urwid.TreeListBox(urwid.TreeWalker(self.top_node))
self.view = urwid.Frame(
self.list_box,
)
def main(self):
loop = asyncio.get_event_loop()
main_loop = urwid.MainLoop(
self.view,
event_loop=urwid.AsyncioEventLoop(
loop=loop,
),
unhandled_input=self.unhandled_input
)
main_loop.run()
def unhandled_input(self, key):
if key in ('q', 'Q'):
raise urwid.ExitMainLoop
I want to get rid of a SEARCH RESULTS node, basically.
*I tried to use a for loop and it always says syntax error
do u know if urwid doesn’t support for loops?
which breaks when the widget in it is a placeholder that is initially not selectable, but is later swapped for a selectable one
should I just initialize it with a selectable placeholder? or should Pile stop caching _selectable and instead always delegate it when it's called?
which works, but it was a bit nontrivial to figure out
list_widgets = urwid.SimpleListWalker([])
...
list_widgets.set_focus(list_widgets.positions(reverse=True)[0])
but this shows only the item before the last one
what am I doin wrong?
(the hiearchy is Frame -> ListBox -> SImpleListWalker and everything is in default settings)
Hello. Some time ago I asked about mnemonics in Urwid on StackOverflow. The question, quite short and with images, is here: https://stackoverflow.com/questions/61969402/urwid-button-mnemonic-keys. I haven't received any reply there. Is this feature available in Urwid under a different name?
