Message Box Question(please read)

Question

Okay, so I have a message box script that I made and everything is going perfect except sometime the text is too much for the size of the box. Is there any way I can make the box's height/width change according to how much text there is?

I found something in the GUI docs that can be usefull:

http://unity3d.com/support/documentation/ScriptReference/GUIStyle.CalcSize.html

It shows an example where the rect is calculated according to the label parameter:

 function ProgressBar (value : float, label : String) {
     var size : Vector2 = GUI.skin.GetStyle("ProgressBarText").CalcSize(GUIContent(label));
     var rect : Rect = GUILayoutUtility.GetRect (size.x, Mathf.Max(size.y));
     rect = Rect(rect.x + 4, rect.y, rect.width -8, rect.height);
     EditorGUI.ProgressBar (rect, value, label);
     EditorGUILayout.Space();
 }

I've not tested this, and I think the GUI docs are somewhat incomplete and obscure, but maybe this can help you.

this may help

 void OnGUI()
 {
     GUI.ModalWindow(0, new Rect(Screen.width / 2 - Screen.width / 5, Screen.height / 2 - Screen.height / 4, Screen.width / 5 * 2, Screen.height / 4 + 20), DialogWindow, "");
 }

 private bool showDialogWindow;

 public void DialogWindow(int id)
 {
     {
         GUILayout.BeginVertical();
         {
             GUILayout.Label("Use this item?");
             GUILayout.Space(20);
             GUILayout.BeginHorizontal();
             {
                 GUILayout.Space(20);
                 if (GUILayout.Button("Yes"))
                 {
                     if (selectedUseItem)
                     {
                         DoSomething();
                         showDialogWindow = false;
                     }
                 }
                 if (GUILayout.Button("No"))
                     showDialogWindow = false;

                 GUILayout.Space(20);
             }
             GUILayout.EndHorizontal();
         }
         GUILayout.EndVertical();
     }
 }
