How to get UI element size property with Unity UI toolkit

I'm trying to get and store the width of a UI element (using the Unity UI toolkit) for later calculation:

int width = SomeGroupBox.style.width.value;

Where the group box is acquired by SomeGroupBox = GetComponent<UIDocument>().rootVisualElement.Q<GroupBox>("NameOfGroupBox"); .

But Unity refuses to give me the width and showed:

Error CS0029 Cannot implicitly convert type 'UnityEngine.UIElements.Length' to 'int'

Explicitly casting it into int also did not work, neither does the float or long type.

Is there a way to use the UnityEngine.UIElements.Length type as int?

Solution

  • To get the dimensions of a UI element it is recommented to use resolvedStyle

    So in your case:

    SomeGroupBox = GetComponent<UIDocument>().rootVisualElement.Q<GroupBox>("NameOfGroupBox");

int width = SomeGroupBox.resolvedStyle.width;
