Question

Here is the code I am using:

JMenu menu = new JMenu("Menu");

JMenuItem item = new JMenuItem("Add");
item.add(new JButton("SOMETHING A BIT WORDY"));
menu.add(item);

// ... 
JMenuBar menuBar = new JMenuBar();
menuBar.addMenu(menu);
JFrame frame = new JFrame();
frame.setJMenuBar(menuBar);

// ...
frame.pack();
frame.setVisible();

However, the button (inside of the menu item) appears small and only contains the text “…” which is used when the button’s size cannot fit the intended text. Is there any way to make my JMenuItem “grow” to fit my JButton (or JTextArea, or JLabel, or whatever the Component may be)?

Answer 1

I totally agree with others who posted their comments, it may be an odd mix to put an button in the menuitem, if you insist to this, setPreferredSize can solve your problem.
I used a bad hard code implementation, if anyone know how to set the width dynamically, please guide me too. 😛 thx in advance.

JMenu menu = new JMenu("Menu");

JMenuItem item = new JMenuItem("Add");
item.add(new JButton("SOMETHING A BIT WORDY"));
item.setLayout(new FlowLayout()); // set FlowLayout for item
item.setPreferredSize(new Dimension(200, 100)); // hard code implementation :-(
menu.add(item);

// ... 
JMenuBar menuBar = new JMenuBar();
menuBar.add(menu);
JFrame frame = new JFrame();
frame.setJMenuBar(menuBar);

// ...
frame.pack();
frame.setVisible(true);
