Change font of dialog box

Question

I am using JOptionPane as dialog box for my application.
Could anybody tell me how to change the font properties of JOptionPane?
Thanks a lot.

Answer 1

I've tried a lot of ways to change the font of the Labels and Buttons in JOptionPane.
But I still can't change the Input Dialog.
Here is the way that I change the fonts of buttons of JOptionPane:
String message;//Message to display
String title;//Title of the dialog
Icon icon;//Icon to display
JOptionPane op = new JOptionPane(msg,JOptionPane.QUESTION_MESSAGE, JOptionPane.OK_CANCEL_OPTION, icon, new Object[] {"Yes", "No"}, "No");
//panel1 is the panel that holds the buttons
JPanel panel1 = (JPanel)op.getAccessibleContext().getAccessibleChild(1);
//the panel that holds labels is op.getAccessibleContext().getAccessibleChild(0);
//but labels can use embedded HTML, that's more easier than doing like this.
//then get the components that you want to change.
//get the first button
JButton btnYes = (JButton)panel1.getAccessibleContext().getAccessibleChild(0);
//get the second button
JButton btnNo = (JButton)panel1.getAccessibleContext().getAccessibleChild(1);
//then set the font, here I set them different to show that it does work!
btnYes.setFont(new java.awt.Font("SansSerif", 0, 11));
btnYes.setFont(new java.awt.Font("SansSerif", 0, 12));
//then show the dialog...
op.createDialog(null, title).setVisible(true);
But it seems rather ugly...and I can't do this to the input dialog, because
i don't know how to create a JOptionPane instance for input component(TextField
or ComboBox), but just write JOptionPane.showInputDialog(....) as a default one.
