Is something wrong with the construction of this class? I am trying to add an instance of it to a JPanel in another class:
public class calculator2 extends JPanel {
public calculator2() {
JPanel x = new JPanel();
x.setLayout(new GridLayout(0,5));
x.add(new JLabel());
x.add(new JButton("<<"));
x.add(new JLabel());
x.add(new JButton(">>"));
x.add(new JLabel());
}
}
This is what I am trying to use it on:
calculator2 test = new calculator2();
JPanel panel3 = new JPanel(new BorderLayout());
panel3.add(test, BorderLayout.SOUTH);
I dont get any type of run time error,it just dosen't show up. When I put the code from the calculator2 class in the same class I am using in the second portion of code it shows up. Thank you for your consideration.
This is actually just an example, I have a full class with about 25 components using actionlisteners and the like and wanted to add it to a panel using the above method.
Here you are just creating the panel without adding it anywhere to be seen. Try using the parents methods inherited from JPanel instead of creating a new instance of another JPanel in the constructor.
This will be , just remove the instance called x.
public class calculator2 extends JPanel {
public calculator2() {
super();
setLayout(new GridLayout(0,5));
add(new JLabel());
add(new JButton("<<"));
add(new JLabel());
add(new JButton(">>"));
add(new JLabel());
}
}
