GUI splitter control
How can I make a GUI splitter control, similar to the splitter the console has?
1 using UnityEngine; 2 using UnityEditor; 3 4 public class GUISplitter : EditorWindow { 5 Vector2 posLeft; 6 Vector2 posRight; 7 GUIStyle styleLeftView; 8 GUIStyle styleRightView; 9 float splitterPos; 10 Rect splitterRect; 11 Vector2 dragStartPos; 12 bool dragging; 13 float splitterWidth = 5; 14 15 // Add menu named "My Window" to the Window menu 16 [MenuItem ("GUI/GUISplitter")] 17 static void Init () { 18 GUISplitter window = (GUISplitter)EditorWindow.GetWindow ( 19 typeof (GUISplitter)); 20 window.position = new Rect(200, 200, 200,200); 21 window.splitterPos = 100; 22 } 23 24 void OnGUI (){ 25 if (styleLeftView == null) 26 styleLeftView = new GUIStyle(GUI.skin.box); 27 if (styleRightView == null) 28 styleRightView = new GUIStyle(GUI.skin.button); 29 30 GUILayout.BeginHorizontal (); 31 32 // Left view 33 posLeft = GUILayout.BeginScrollView (posLeft, 34 GUILayout.Width (splitterPos), 35 GUILayout.MaxWidth(splitterPos), 36 GUILayout.MinWidth(splitterPos)); 37 GUILayout.Box ("Left View", 38 styleLeftView, 39 GUILayout.ExpandWidth(true), 40 GUILayout.ExpandHeight(true)); 41 GUILayout.EndScrollView (); 42 43 // Splitter 44 GUILayout.Box ("", 45 GUILayout.Width(splitterWidth), 46 GUILayout.MaxWidth (splitterWidth), 47 GUILayout.MinWidth(splitterWidth), 48 GUILayout.ExpandHeight(true)); 49 splitterRect = GUILayoutUtility.GetLastRect (); 50 51 // Right view 52 posRight = GUILayout.BeginScrollView (posRight, 53 GUILayout.ExpandWidth(true)); 54 GUILayout.Box ("Right View", 55 styleRightView, 56 GUILayout.ExpandWidth(true), 57 GUILayout.ExpandHeight(true)); 58 GUILayout.EndScrollView (); 59 60 GUILayout.EndHorizontal (); 61 62 // Splitter events 63 if (Event.current != null) { 64 switch (Event.current.rawType) { 65 case EventType.MouseDown: 66 if (splitterRect.Contains (Event.current.mousePosition)) { 67 Debug.Log ("Start dragging"); 68 dragging = true; 69 } 70 break; 71 case EventType.MouseDrag: 72 if (dragging){ 73 Debug.Log ("moving splitter"); 74 splitterPos += Event.current.delta.x; 75 Repaint (); 76 } 77 break; 78 case EventType.MouseUp: 79 if (dragging){ 80 Debug.Log ("Done dragging"); 81 dragging = false; 82 } 83 break; 84 } 85 } 86 } 87 }
