having spent a couple of days implementing zooming and panning canvas with GUI elements with old IMGUI + editor window, I decided to ask this (with zero time spent reading UIElements docs):
A. Is it possible to zoom Editor window Rect contents in similar manner to GUI.Matrix, but with less issues, like clipping on left/up directions?
B. Is there some sort of “canvas” like world space and viewport concept in UIElements or do we still need to simulate view position / zooming manually by moving objects or by using some view position offset to place stuff?
I’m asking this so that I can consider if I want to already try using UIElements or not :).
All major GraphView-based tools (ex. ShaderGraph, VFX Graph) released in the last year+ use UIElements. If you try any of them, you’ll see how UIElements performs when zooming and panning.
Zooming and panning in UIElements is really easy. Elements are hierarchical and have a transform. You are free to transform them (and their children) any way you want.
Sorry for bumping an old thread, but it seemed relevant - how are you supposed to transform them, when the VisualElement.transform property, the VisualElement.style property, and the VisualElement.worldBounds property are all read-only? I don’t understand what API I should be using to make transform changes programmatically.
edit: I now realize that while the style property is read-only, you can make changes to it that are persistent.
Just to make this clear both VisualElement.transform and VisualElement.style are not read only.
ITransform interface has setter for position, rotation and scale.
IStyle interface has setter for all style properties.
