Question

I am currently in a midst of developing an desktop application. I have the menu bar, which has the RUN command with the ALT-R mnemonic. Also, I have a RUN button in one of the frames & I have declared an ActionListener for the same. Is there a way to use the same ActionListener for the RUN command menu-item..? Or should it be re-declared all the way again..?

Answer 1

If you calling second class from first then you can pass the class where you implemented the ActionListener to second class. i.e.

class A implements ActionListener{
   @Override
   public void actionPerformed(ActionEvent ae) {
     //--- coding.........
   }

   //--- Somewhere in this class
   B b=new B(this);
}

class B{
   A a;
   public B(A a){
      this.a = a;
   }
   //-- now use this.a where you wanna set actionListener
}

Or you can also easily pass it as:

class B{
  //-- Where you want to add ActionListener
    button.addActionListener(new A());
}
