    I realy hope I'm not being a complete maroon here, and yes I've searched....but, it seems that GUI.changed does not flag clicks or changes to GUI.Textfield? It seems to me that would be real handy, just like it is for the other GUI controls.

    Code (csharp):
    1.     void OnGUI()
    2.     {
    3.         text1 = GUI.TextField(new Rect(50, 50, 100, 100), text1);
    4.  
    5.         if( GUI.changed )
    6.             print( "text field change");
    7.     }
    8.

    I don't think the method GUI.changed is a good idea, what if you have lots of GUI components with different types?
    I prefer codes like this:
    Code (csharp):
    1.  
    2. TextField myText1=new GUI.TextField();
    3. myText1.setLocation(new Rect(0,0,100,100));
    4. myText1.setTexture(myTexture);
    5. string content="show here";
    6. myText1.setContent(content);
    7. myText1.Show();//show the textfield on the screen
    8. if(myText1.isChanged)
    9. {
    10.   Debug.Log("new textField content:"+content);
    11. }
    12.

    wisly, thank you, I appreciate the reply. I like your idea. However, in your example, you are using TextField as a type, which it is not (it is a method). And you are using "setLocation" and those other methods, which I can find nowhere, expecially not "isChanged". ??? Am I missing something?

    I would do something like:
    Code (csharp):
    1.  
    2. private string typedText;
    3.  
    4. void OnGUI()
    5. {
    6.     string newText = GUI.Textfield(new Rect(),typedText);
    7.  
    8.     if(newText != typedText)
    9.     {
    10.         Debug.Log("Textfield changed!");
    11.     }
    12.  
    13.     typedText = newText;
    14. }
    15.

    No, you are not.
    That kind of method is just what I think.
    it's not really provided by the unity3d at this time.
    In fact,
    Lukas 's suggestion is really useful and possible.
    or maybe you can create a custom class to implement that.
