GridBag Style Layout?

With the current layout schemes you aren't allowed much variation (save for doing it yourself.) I would like something akin to GridBag layouts (or even just better horizontal and vertical). Currently I have a horizontal layout where I want one element to always take up 80% of the width and the other two to take up 15% and 5% I currently see no way of doing this, save for sizing it myself. Are any of the layout tools sufficient for this? Or will we need to make do and wait?

It would also be nice to be able to pad pieces of components away from their edges by a set amount without using one of the strict layouts.

 

Like Java's GridBag where you have to set constraints left and right?
What about something like Qt's nested layouts?
A vertical layout that can contain a horizontal layout (without creating an additional panel!), and gracefully resizes by itself without specifying a ton of constraints?

 

Yes. You said you have a Horizontal Layout Group. Add a LayoutElement to each child and set the FlexibleWidths to 80, 15, and 5. Make sure Minimum and Preferred Widths are all 0.

The basic anchoring functionality can be used to make a rect be a set distance away from the edge of the parent.

 

Ah, I didn't know the internal LayoutElements could override the Horizontal/Vertical layouts. Thank you.

 

Sadly the grid-layout doesn't appear to support this functionality - the ratio fitter doesn't play nicely.

I would like my primary layout to consist of 3 elements, a central square, and an element that fills from the bottom left, and one from the top right.

This would provide space at the sides on landscape, and at the top in portrait - those elements could sort themselves out once everything else is in order. I can't seem to pin things to the parent and have them grow, and the grid forces element's sizes.

 

It's inconvenient that the grid doesn't work for this, but what does seem to work is having a panel (just a rect-transform and nothing else) with a vertical layout, then panels for each row with horizontal layouts, then the elements arranged inside. This works only if you know ahead of time your number of rows/columns, though.

 

For my case, this wouldn't work, as I want my primary layout to switch between horizontal and vertical, a grid layout would change the order nicely, but so would having layout elements working on a non-layout group.
