TabBar: Ability to make tabs expand to fill blank space

[devvoid]

It would be extremely useful if there were some way of making tabs expand to fill all empty space in a TabBar, in a way similar to a control's "expand" size flag.

Here's an example of what I mean: On the left is a standard TabContainer, while on the right is a hacked-together mockup I made, which is an HBoxContainer full of buttons with their horizontal size flags set to "expand".

This looks much better visually, especially in situations where there's a fixed number of tabs and the amount will never change, but obviously to implement this in an actual game would take a lot of re-implementing TabContainer's functionality. It would be incredibly useful if there were just a property you could set to make this happen - maybe another entry on the AlignmentMode enum?

I've no idea why isn't this a thing. Anyway currently to implement it by code?

I don't think so, not without manually calling "set_tab_title" and padding the title with whitespace to get the correct size.

I second that this would be a very useful feature, it seems that everything related to tab sizing is done internally and there is no way to really override it. At the very least I wish there was an option to set a minimum width for the tabs.

Probably doable, will have a look to try to implement it

[TheZomb]

@davthedev I've currently already started implementing it, but would be glad if we could work together on it. That would make both our lives easier. Let's get into contact via mail

[davthedev]

To kill two birds with one stone, we can use this opportunity to implement an actual "tab alignment" setting.

[TheZomb]

yeah that sounds great. and it should also work fine with the function of having tabs larger than the tab bar width hidden and cyclable. All in all, the only thing that needs to be implemented actually is being able to set tab min width I think. Everything else should be doable with the currently implemented features

If you put this code in a Tab Container it should add space to both sides of your Tabs:
