and if not map, then perhaps inject?

valadaa48

@valadaa48

ok I figured out the method of injecting input

@wardi

@valadaa48 reminds me of http://excess.org/article/2010/03/urwid-crystalfontz-635-lcd/

@valadaa48

aha, this is an embedded arm device I have

it's working great btw using pipes

and I really love what you've done

at first I tried ./myapp.py < /dev/input/event2 but urwid choked on get key (assuming the input are keyboard scancodes). Allowing the control mapper to map any uinput code like KEY_ENTER, BTN_JOYSTICK_EAST would actually open up urwid to practically any uinput device

/usr/include/lirc/include/linux/input-event-codes.h

@valadaa48

also, does urwid support attributes in strings? like f"{color.RED}hello {color.BLUE}world"

@valadaa48

@wardi if I wanted to create a 2 column layout in a Frame, setting the body to Columns([Text("foo"), Text("bar")]) doesn't seem to work

Ideally I'm looking for a 40%/60% split

valadaa48

@valadaa48

got this working

@valadaa48

how can I disable a component from being selectable?

tonycpsu

@tonycpsu

add a selectable method that returns False

valadaa48

@valadaa48

@tonycpsu thank you. So I take it the only way is to subclass all of my various components?

valadaa48

@valadaa48

monkey patch looks to be the ticket here

valadaa48

@valadaa48

my top-level component is a frame, I would like to add a popup window. Would I need to convert top-level to be an overlay for this to work?

also, if I wanted a popup on top of a popup, is this achievable?

sorry for all the questions but I think my app is nearly complete and I think urwid is fantastic

the last bit of workflow I'm trying to achieve is: popup context window when clicking on a menu item and this context window would have the ability to popup a confirmation dialog

tonycpsu

@tonycpsu

@valadaa48 i've never done a popup from a popup but it should work

examples/pop_up.py shows how it works

valadaa48

@valadaa48

thank you

I'm setting loop.widget = term (Terminal) if the user hits a button but I'm not sure how I might be able to exit out of the terminal using a keystroke back to the main menu

valadaa48

@valadaa48

ok figured that one out

valadaa48

@valadaa48

is the advised way of having multiple "screens" to replace loop.widget?

i.e, if I have 2 Frames the user can switch via F1/F2

Ian Ward

@wardi

@valadaa48 WidgetPlaceholder IIRC

then you're not tied to switching loop.widget, you can switch out widgets wherever you need

valadaa48

@valadaa48

ok great

my app is coming along nicely

I'm very glad I tried urwid before doing this in python curses directly

Is there a way to have a urwid app to do a sys.exit() after a configurable timeout if no input has been received from the user in more than 30 seconds?

Neil Pilgrim

@neiljp

Is there some way to get horizontal layout that I'm missing, that allows multi-line/row flow but isn't fixed width like GridFlow? Columns don't seem to accept flow over multiple rows except within boxes of a given row, which isn't quite what I'm looking for.

Some columns that are too wide just don't get rendered in a fixed width, which I can avoid using a box-column right now, but doesn't really give the right layout.

Neil Pilgrim

@neiljp

I'm thinking of something like a GridFlow, but where it flows onto multiple lines if there isn't enough space to fit on one line. A good example might be something like 'breadcrumbs', ie. "large area > smaller area > tiny", where they might be broken up into multiple lines at the '>' boundary if the width shrinks, but in chunks a little like Columns, over multiple rows like GridFlow but not with fixed widths for each chunk.

Ian Ward

@wardi

you might need to make your own widget that manages its children the way you want, take a look at the source for GridFlow IIRC it uses Columns and Pile widgets based on the size given

Neil Pilgrim

@neiljp

This seems like a fairly useful general case, ie. horizontal flow, and I was surprised it wasn't a standard widget - do you think it could be one if it was developed?

Ian Ward

@wardi

sure if it's general enough

valadaa48

@valadaa48

has anyone worked out a way of getting more than 16/8 colors in the linux console?

I don't think it's supported but figure you guys might know of any tricks

also utf-8 glyphs seem to be a challenge as well

Neil Pilgrim

@neiljp

unicode works for me, but only the simpler ones, and presumably it depends on the font too.

Neil Pilgrim

@neiljp

We definitely have issues with 'complex' unicode in zulip-term, which is why we currently default to expand emoji into short names - it tends to shift the layout otherwise, in some cases.

valadaa48

@valadaa48

is that in the linux console or via x/wayland?

valadaa48

@valadaa48

class MyButton(urwid.Button):
    def __init__(self, caption):
        super(MyButton, self).__init__("")
        self._w = urwid.AttrMap(
            urwid.SelectableIcon(caption, 0), "button", "button_focus"
        )

I'm using that, but I can't seem to make not selectable

I tried button._selectable = False

valadaa48

@valadaa48

anyone aware of an onscreen keyboard implementation within urwid?

@ulidtko

@mimansa-dev Is there a way to have a urwid app to do a sys.exit() after a configurable timeout if no input has been received from the user in more than 30 seconds?

Yes. Check out urwid.MainLoop, it has methods to set timers
