JTextField overriding

[kohinoor2007]

Hi guys,

Have a class ,which Iam extending from "JTextField" under swing.Want to overide the " setText" function as follows:
Want to set a flag before I call the super class "SetText".How could I achieve it....

public void setText(String text){

val = true; // "Val" is a boolean declared in the class.
super().setText(text); // this gives a compile time error.
val = false;
}


Have implemented a DocumentEvent which is fired each time characters are inserted or removed from a text component.

The event is also fired if the set of attributes in the text component is changed.That I want to avoid.Thats why Iam overriding the "setText".

How can I modify my overrided "setText" function the way I have described,so that I can call the super "setText" function...


Thanks in advance......

I think you need to drop the () after super.

super.setText(text);

 

[kodr]

super() is used for constructors. I think, still new to Java.

kdor is right. Does your example compile?

What you can do is adding a listener that will only throw the events if they come from a text change.

Cheers,
Dian
