存在足够空间时,应向此布局元素分配的首选宽度。
可将 preferredWidth 设置为 -1,以删除该大小。
using UnityEngine; using System.Collections; using UnityEngine.UI; // Required when using UI elements.
public class ExampleClass : MonoBehaviour { public Transform MyContentPanel;
//Sets the flexible height on on all children in the content panel. public void Start() { //Assign all the children of the content panel to an array. LayoutElement[] myLayoutElements = MyContentPanel.GetComponentsInChildren<LayoutElement>();
//For each child in the array change its LayoutElement's preferred width size to 250. foreach (LayoutElement element in myLayoutElements) { element.preferredWidth = 250f; } } }
