Question: How to center a grid?

[LBCrion]

I pushed the initial implementation of the 3 grids into the main git branch. You can pack widgets into "start", "center" and "end" grids. If you omit grids name, it will be assumed to be the start grid, this should preserve compatibility with the existing configs. You may need to have a start grid in the current version even if it's empty. I'll fix this limitation on the next update. Can you check if this works for your use case please?

I.e. if we specify center alignment, where in the central grid will the widget go?

This is actually not a simple question. Gtk allocates space evenly between widgets configured with expand set to true, so adding a tray on one side will skew the center (since the two labels get expanded to equal size). The only certain way to achieve this that is to implement left, center and right grids and pack widgets into these. It should be easy to implement, but I need to think of how to do this right in terms of configuration. I'm currently thinking of allowing multiple layout sections, I.e.: Layout("left") {...} Layout("center") {...} Layout("right") {...} If the default Layout is "left", we should get the current behaviour.

Another way to do it in my opinion is to have an "align" variable inside the widget, like:

grid {
      align = "center"
      ...
  }

and if it's not defined in the user's configuration then set it to left as in default. This way when you release the update people don't have to update their configuration file.

It works perfectly! I will open a new issue if I encounter any problems.
Thanks for all your hard work!

I may introduce a slight breaking change for start/ center/ end layouts. The names will need to have a leading ':', I.e. change "center" to ": center". The intention is to allow running multiple bars in the same process, so layouts can be named to contain both a bar id and a grid I'd, I.e. "bar1:center". Bar id will be optional if you just want a single bar, so for a single bar you'll just need to add a leading ':'. I think it's better to make the naming change now, before grid id feature makes it into a release. I'll let you know when I push this change into git.

The new names should now work in current git.
