GUILayout.Box and OnMouseEnter not firing

My Issue: I can't get OnMouseEnter events from a GUILayout.Box.
My Goal: To create a GUI that has a large table or tree view of information from which the user can select an item or range of items.
My Experience: years in coding, but very little with Unity and immediate mode GUI coding.
My System: Unity 2.6.1 on Snow Leapord

I'm experimenting with a long list of Box controls in a scroll view as follows. The script is tied to my Main Camera. Any ideas why I'm not getting the event or suggestions on how I can better achieve my goal? Thanks!


void OnGUI() {
GUI.skin = theSkin;
if (isVisible)
{
Rect outer = new Rect((Screen.width - WIDTH), (Screen.height - HEIGHT) - 40, WIDTH, HEIGHT);
scrollPosition = GUI.BeginScrollView(outer, scrollPosition, new Rect(0, 0, WIDTH-30, 60000), false, true);

GUILayout.BeginVertical();
mEnumerator.Reset();
while (mEnumerator.MoveNext())
{
mItem = (MyItemType)mEnumerator.Current;
GUILayout.Box(mItem.Name.ToUpper() + ":", myOptions);
GUILayout.Box(mItem.Text, textStyle, mOptions);
}
GUI.EndScrollView();
}

}
void OnMouseEnter() {
Debug.Log("OnMouseEnter");
}
void OnMouseOver() {
Debug.Log("OnMouseOver");
}

void OnMouseExit() {
Debug.Log("OnMouseExit");
}

 

I'm definately not entirely confident to be giving advice, since I've only been going for a few days, but since you're in the OnGUI(), you might want to look at this, for getting mouse events

Event.current

ie inside the OnGUI()

Code (csharp):

1.  
2. if (Event.current.type == EventType.mouseUp) {
3.  
4. }
5.  

You can just do a Debug.Log (Event.current); to get a stream of events inside the onGUI.

 

The OnMouseXXX functions work when the mouse moves over an object with a collider or a GUIText/GUITexture component. You can check if the mouse position is within a control's rectangle using Rect.Contains.

 

Thanks for the replies.
It seems like I can get the job done using Button because I'll know exactly which button was pressed and I can tag my item as selected. Whereas with Event and Box, I'm not sure I'm guaranteed that the mouse event came from the last Box I drew.

Do you think there is significant overhead using Button versus Box or Label? I have 1600 buttons in a Scroll View and I'm surprised how fast it's rendering my table on my MacBook. I want this to work on an iPad.
