数组到JLabel

Question

I have two Packages with java Class

• PKStrings
• PkJforms

---

public class classWork {
    public String[] titleMenu={
        "A","B","C","D"
    };

    public int intOption;
}

I have JFrame with menu

• A click go jframe A,

  B click go jframe B,

  C click go jframe C,

  D click go jframe D

And other frame in same package JFram01 , contains JLabel .

How to recognize if you click on "A" and show that position label?

Answer 1

I dont understand your need. "A click A go jframe A" doesnot make sense.
if you want to go to another jFrame when clicking a label
Try this

    private void yourlabelMouseClicked(java.awt.event.MouseEvent evt) {
          //  either you can hide the current jFrame by setting 
            jFrame.setVisible(false);
            newjFrame.setVisible(True);
                    or
            make these jFrames in 2 different classes that make simple invocations
        }

Answer 2

From what i understand u can use a public variable in your package and store value in it using the on click event on A, B, C .....

then access that info from the jfaram you want

eg

public String pos ="";

A onclick event(){
   pos="A";
}


finally

if(pos.compareto("A")==0){
   jlabel.settext("A");
}
