A fixed-size button...
public class ArrowButton extends BasicArrowButton {
private Dimension pref;
public ArrowButton(int type, Action action) {
super(type);
int size = new JComboBox().getPreferredSize().height - 1;
pref = new Dimension(size, size);
addActionListener(action);
}
public Dimension getMaximumSize() { return pref; }
public Dimension getMinimumSize() { return pref; }
public Dimension getPreferredSize() { return pref; }
}
A text field that won't expand vertically...
public class BaseDialog extends JDialog {
public static JTextField stdTextField(int columns) {
final JTextField tf = new JTextField(columns) {
public Dimension getMaximumSize() {
Dimension max = super.getMaximumSize();
Dimension prf = getPreferredSize();
return new Dimension(max.width, prf.height);
}
};
