Staggering buttons with GUI.SelectionGrid

Question

I'm trying to offset buttons so they are layed out at a diagonal from each other. Each one corresponds to a different view of the screen; so, it would make sense to use GUI.SelectionGrid to have the buttons provide feedback for which screen the user is currently on. Is there anyway to do this with one SelectionGrid? I was thinking placing them in a GUILayout would be the way to go. If that's the right path would it just take nesting the SelectionGrid between GUILayout.BeginHorizontal and BeginVertical?

Here's a screen shot of what I'm attempting to accomplish:

The SelectionGrid just seems like the class I want to use to have selected buttons highlighted.

There is no way to align the items within a selection grid afaik. I used toggle buttons with a button skin for that and controlled their state by an array.

just a small example:

 bool[] myStates = new bool[3]{true, false, false};

 ...

 GUILayout.BeginHorizontal(); //your custom layout instead
 {
     if(GUILayout.Toggle(myStates[0], "Pay", myButtonStyle))
     {
         CheckState(myStates, 0);
     }
     if(GUILayout.Toggle(myStates[1], "Politics", myButtonStyle))
     {
         CheckState(myStates, 1);
     }
     if(GUILayout.Toggle(myStates[2], "Strike", myButtonStyle))
     {
         CheckState(myStates, 2);
     }
 }
 GUILayout.EndHorizontal();

 ...

 protected void CheckState(bool[] values, int selectedIndex)
 {
     for (int i = 0; i < values.Length; i++) 
     {
         values[i] = i == selectedIndex;
     }
 }

oh yeah, and I could just skin the toggles to look more like a button.

Additionally an example for the skin config:

I have just one question about your code. I noticed commenting out values[i] = i == selectedIndex; stops the selected toggle from switching. How is values[i] changing the value of myStates without passing by reference?

NV$$anonymous$$ arrays are reference types.
