Using GUIStyle on an Editor Script

Hi every one, a got this little problem:

In the Editor Script:

var scroll : Vector2;

function OnInspectorGUI () {
    scroll = EditorGUILayout.BeginScrollView(scroll,, GUILayout.MinHeigth(100));
    // Some Content.

I have tried many ways to draw the scroll view style but I only got this issue:

NullReferenceException: Object reference not set to an instance of an object
UnityEngine.GUILayoutEntry.ApplyOptions (UnityEngine.GUILayoutOption[] options).

I already read the unity manual, and they said it’s possible, this are the options:

BeginScrollView (scrollPosition : Vector2, alwaysShowHorizontal : boolean, alwaysShowVertical : boolean, horizontalScrollbar : GUIStyle, verticalScrollbar : GUIStyle, background : GUIStyle, params options : GUILayoutOption[]) : Vector2.

If any one can help me to understood this, that will be appreciated.
Thanks in advance.

GUIStyle does not have a member “box”, but that actually isn’t the immediate problem. You should look into EditorStyles for more info on styles in the Editor. Also, you can use a GUISkin in your editor as well if you require a lot of skinning!

Your immediate problem is that your last parameter needs to be an array of GUILayoutOption:

var scroll : Vector2;
function OnInspectorGUI () {
scroll = EditorGUILayout.BeginScrollView(scroll, new GUILayoutOption[1]{GUILayout.MinHeight(100)});
// Some Content.

Hope that helps.


Sorry for the delay, but according to some tests carried out, certain options can be used to modify the view in the inspector using the default guiskin.

Like this:

var numbers : int;

// On the GUI function in editor script.
numbers = EditorGUILayout.IntField("Value", numbers, "box", GUILayout.MinWidth(100));

This will show an IntField with “box” style.
