Dynamic Component Creation

Question

Hi,
Can someone tell me if there is a way to get the following code to work or another way to get the same effect? I want to be able to create buttons on demand, when the user clicks an "add" button.
JPanel numpanel = new JPanel();
int i;
for(i = 1; i<13; i++){
JButton ("num"+i) = new JButton(("Num-" + i));
numpanel.add(("num"+i));
}

Answer 1

Do you need to hold a reference to the buttons or do yo just want to add them to the panel?
If you just need to keep adding buttons, then use this:
//asssume count is a class level variable
numpanel.add(new JButton("Num-" + count++));If you need to hold a reference to each button (quite likely), then use an ArrayList/Vector to hold the buttons
JButton b = new JButton("Num-" + count++);
list.add(b);
//--- list is the ArrayList that has been created and initialised.
numpanel.add(b);When you need to retrieve any button, use list.get(i).
