get dimensions of area

[nschloe]

For my top-equivalent in Textual, I draw a bunch of graphs in areas:

    class TiptopApp(App):
        async def on_mount(self) -> None:
            grid = await self.view.dock_grid(edge="left")

            # 8/13: approx golden ratio :)
            grid.add_column(fraction=8, name="left")
            grid.add_column(fraction=13, name="right")

            grid.add_row(size=1, name="topline")
            grid.add_row(fraction=1, name="top")
            grid.add_row(fraction=1, name="center")
            grid.add_row(fraction=1, name="bottom")

            grid.add_areas(
                area0="left-start|right-end,topline",
                area1="left-start|right-end,top",
                area2="left,center",
                area3="left,bottom",
                area4="right,center-start|bottom-end",
            )

            grid.place(
                area0=InfoLine(),
                area1=CPU(),
                area2=Mem(),
                area3=Net(),
                area4=ProcsList(),
            )

In the widgets that generate the graph, I would like to have some way of knowing the dimensionality of the area such that I can scale the graphs accordingly. I'd also like to have some "resize" event that I can act upon.

Is this available yet?

That looks great!

There is a resize event, which will give you the new dimensions of the widget.

[nschloe]

Is this information available on_mount, too?

[willmcgugan]

It's not. The mount event happens prior to the layout, but you will get a resize event immediately after (but before rendering).

[nschloe]

but before rendering

That's good enough. Thanks!

Hi,
I was wondering where these functions InfoLine, CPU, Mem, Net and ProcsList are coming from?
Is there a standard module where they can be imported from?
Or have you made them yourself from modules such as platform?
Thanks for your reply.

Or have you made them yourself from modules such as platform?

An psutils, yes.

thanks.
Should you ever want to share this code, i am interested!
