Shows an Editor window using popup-style framing.
This means the window has no frame, and is not draggable. It is intended for showing something like a popup menu within an existing window.
Opening a window using this method will not give it the functionality of a popup window, only the styling. For full popup functionality (eg, auto closing when the window loses focus), use PopupWindow.
using UnityEngine; using UnityEditor; using UnityEngine.UIElements; public class ShowPopupExample : EditorWindow { [MenuItem("Examples/ShowPopup Example")] static void Init() { ShowPopupExample window = ScriptableObject.CreateInstance<ShowPopupExample>(); window.position = new Rect(Screen.width / 2, Screen.height / 2, 250, 150); window.ShowPopup(); } void CreateGUI() { var label = new Label("This is an example of EditorWindow.ShowPopup"); rootVisualElement.Add(label); var button = new Button(); button.text = "Agree!"; button.clicked += () => this.Close(); rootVisualElement.Add(button); } }
