Question

given i have a button that would be added to different panels am i right to say instantiating 1 JButton is not possible?

example: added a “Cancel” Button to exit application and adding it to a Tab Pane with a certain amount of tabs.

can i do

JButton btnCancel = new JButton(“Cancel”);

and in one of the JPanel for the 1st tab of the JFrame
tab1.add(btnCancel);

2nd tab
tab2.add(btnCancel);

or must i create a new JButton for each tab pane?

Answer 1

Put it below the tab pane. So your hierarchy would look like this:

• JFrame
  • JTabbedPane
    • JPanel for tab 1
    • JPanel for tab 2, etc.
  • JButton cancel
