[solved] what is the difference between label and button

I want to design an gui editor.
the following is my code(SimpleLabel.cs):


using UnityEngine;
using System.Collections;

[ExecuteInEditMode()]
public class SimpleLabel : MonoBehaviour
{
public Rect location = new Rect(0, 0, 100, 100);
private bool _startDrag = false;
public string textLabel;
public GUIStyle textStyle = new GUIStyle();
public string labelId;



void OnGUI()
{
//refresh the main camera.
Camera.main.transform.Translate(new Vector3(0, 0, 0));

//GUILayout.Label(GUI.depth.ToString());
if (Event.current.mousePosition.x >= location.xMin
Event.current.mousePosition.x <= location.xMax
Event.current.mousePosition.y >= location.yMin
Event.current.mousePosition.y <= location.yMax
Event.current.type == EventType.mouseDown)
{
//Debug.Log("Mouse Down");
_startDrag = true;
}


if (_startDrag Event.current.type == EventType.mouseDrag)
{
{
if (Event.current.button == 0)
{
location.x += Event.current.delta.x;
location.y += Event.current.delta.y;
}
else if (Event.current.button == 1)
{
location.width += Event.current.delta.x;
location.height += Event.current.delta.y;
}
}
}


if (_startDrag Event.current.type == EventType.mouseUp)
{
_startDrag = false;
}
GUI.Box(location, textLabel);
}
}


I also created another file called SimpleButton with similar code(change the Box into Label).

then I add two button and two label to the main camera.

Now the problem is I can change each button position easily,even they are at the same position at first.but I cann't do that on the label. it seems there is a layer on each button, but not on label(box).
Can anyone help me?
Thanks.

 

I'm sorry, I wrote a wrong word.
another file should change the Box(Label) into Button.

 

OK,Now I 've found the problem.
Every time after using Event.Current,
I should add a code Event.current.Used() method,
so that other GUI elements can ignore it.

but I'm still not understand why the button element can ignore the event automatically.

Thanks.

 

because you didn't tell it to.
you need to inform the ui that the focus is "locked" basically (I think its a GUIUtility field / function when I remember read) on the object with id XY. Then it won't react to it on other objects

 

Thanks for reply,dreamora.
I think you must mean the GUIUtility.hotControl.
Can I use this to tell the ui a Label has caught the focus and prevent other gui components(including label) from achieving the the event again?
