Maintain Aspect anchor

[ghost]

I was looking for this earlier and couldn't find. What I mean is, if any Control-based node occupies 25% of the screen on 480p, it must also occupy 25% of the screen in 1080p. I know how do this manually, you have to set the anchors like this:

Anchor left: pos.x / screen_width
Anchor top: pos.y / screen_height
Anchor right: (pos.x + size.x) / screen_width
Anchor bottom: (pos.y + size.y) / screen_height

But if the UI changes, there's the need to recalculate those anchors. There should be a 'Maintain Aspect' anchor that calculates it automatically using the code above. Or if there is already something that does this, then it should be more visible.

I do know about viewport stretch on the project settings, but then it applies to everything

Godot 3.0 Beta 2

why did you remove issue template? your godot version?

with godot 3.0, you can do it like above.

this will cover top 25% of the screen on whatever screen size.

Maybe another dragging mode, in which it moves anchors instead of margins would help? Potentially it might be triggered by holding Ctrl/Shift/Alt.

I don't really get the problem.
You can drag the anchors using the dedicated helpers (the green pins, activated with the 'h' key).

Also, if you activate smart snapping, anchors can be snapped to the node side, which should solve your problem.

It's in "View"/"Show helpers".

Every control node when selected should show its anchor helpers, disregarding 'Show helpers' option.

When I implemented it @reduz told me it was better not to show them by default. But I'm personally not against the idea. This has to be discussed.

When changing only anchors the node will get strangely relocated, which interrupts workflow. (probably a bug)

Can you open an issue for this one ? With a screen capture if possible, I cannot reproduce. Edit: I managed to reproduce it, and fix it :)

Add a 'Maintain aspect' button to 'Layout' which sets the anchors to the node's boundaries.

Adding a "Set to the node's boundaries" option in "Layout" / "Anchors only", would make sense.
Maybe we can also have a modifier (ctrl, alt or shift) to keep the margin values when moving the anchors too.

This is fixed now.
