Extends JLabel

[Dipke]

Hi,

I want to use my own labels in the programm.
So i have extend JLabel to put my own extentsions in it.

public class Label extends JLabel {
    
    public Label(String s) {
        super(s);
    }
}

But when i want to use the ".setHorizontalTextPosition" on such a Label it does not work.
I get the following error message

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: java.awt.Label.setHorizontalTextPosition

Label label = new Label("text");
label.setHorizontalTextPosition(0);

Why is that ?
The "".setHorizontalTextPosition" is public in JLabel thus an extends of JLabel must have acces to it.

instead i have to make first an implementation of "Label"

public class LabelImpl extends Label {

    public LabelImpl(String s) {
        super(s);
    }    
}

Then this is working.

LabelImpl label = new LabelImpl("text") ;
label.setHorizontalTextPosition(0);

What is the reason for that ?

Kind regards
Dipke

Problem solved.
I have imported the awt.label instead of my label object.
Thats why it was not working

Always a bad idea to name your custom classes the same as a JDK class (and especially so when the name of a class in the java.lang package is duplicated).

That said, are you sure you want to use inheritance? It's usually better to write a method (or a static method in a utility class) that sets the desired attributes of an unextended JLabel.
