Disposable helper class for managing BeginGroup / EndGroup.
BeginGroup is called at construction, and EndGroup is called when the instance is disposed.
When you begin a group, the coordinate system for GUI controls are set so (0,0) is the top-left corner of the group. All controls are clipped to the group.
Groups can be nested - if they are, children are clipped to their parents.
This is very useful when moving a bunch of GUI elements around on screen. A common use case is designing your menus to fit on a specific screen size, then centering the GUI on larger displays.

using UnityEngine;
public class Example : MonoBehaviour { void OnGUI() { // Constrain all drawing to be within a 800x600 pixel area centered on the screen. using (var groupScope = new GUI.GroupScope(new Rect(Screen.width / 2 - 400, Screen.height / 2 - 300, 800, 600))) { // Draw a box in the new coordinate space defined by the BeginGroup. // Notice how (0,0) has now been moved on-screen. GUI.Box(new Rect(0, 0, 800, 600), "This box is now centered! - here you would put your main menu"); } // The group is now ended. } }
| GUI.GroupScope | Create a new GroupScope and begin the corresponding group. |
