size of JComboBox

[jerico]

Hi, I am developing an application for which I need to increase the size of the JComboBox.But it is not getting increased.I used the following technique:

Container cont;
JComboBox valueTypeBox ;
valueTypeBox = new JComboBox();

valueTypeBox.addItem("asia");
valueTypeBox.addItem("india");

cont = getContentPane();
GridBagLayout theLayout = new GridBagLayout();
GridBagConstraints c = new GridBagConstraints();
JPanel hostPanel = new JPanel();
hostPanel.setLayout(theLayout);
c.gridx = 2;
c.gridy = 3;
c.anchor = GridBagConstraints.FIRST_LINE_START;
c.fill = GridBagConstraints.NONE;
c.weightx = 1;
c.weighty = 0;
c.insets = new Insets(10, 0, 0, 40);
hostPanel.add(valueTypeBox,c);

Please suggest as how can I increase the size of the JComboBox.Thanks for help.

We have two method called setPreferedSize(int,int) and setMinimumSize(int,int) . try this it may solve your problem

The size of JComponents depends on the Layout specified by the container.. In order to change sizes and even locations you need to implement LayoutManager and do it as you want.. here is a snippet of it.

container.setLayout(new CustomLayout);
 
    public void layoutContainer(Container parent) {
        Insets insets = parent.getInsets();
 
        Component c;
        c = parent.getComponent(0);   /* the first component you add into the container */
        if (c.isVisible()) {c.setBounds(insets.left+8,insets.top+24,480,248);} /* its location and size */
    }
