EditorWindow.ShowModalUtility

Description

Shows the EditorWindow as a floating modal window.

You cannot interact with the utility window while the Editor is runs. The EditorWindow.ShowModalUtility window is never hidden by the Editor. You cannot dock the utility window to the Editor.

Utility windows are always in front of normal Unity windows. The utility window is hidden when the user switches from Unity to another application.

Note: You do not need to use EditorWindow.GetWindow before you use this function to show the window.
