I have a JPanel containing JButtons and a few other things, and I want the entire panel to have a tool-tip. When I call setToolTipText on the JPanel, the tool-tip only appears in empty spaces within the JPanel.
Is there a way to set a tool-tip on the JPanel such that it applies to the JPanel and its children, or am I stuck with calling setToolTipText on all the children as well?
Create a recursive method:
public static void setToolTipRecursively(JComponent c, String text) {
c.setToolTipText(text);
for (Component cc : c.getComponents())
if (cc instanceof JComponent)
setToolTipRecursively((JComponent) cc, text);
}
Full example:
public static void main(String[] args) {
final JFrame frame = new JFrame("Test");
frame.add(new JLabel("Testing (no tooltip here)"), BorderLayout.NORTH);
final JPanel panel = new JPanel(new GridLayout(2, 1));
panel.setBackground(Color.RED);
panel.add(new JLabel("Hello"));
panel.add(new JTextField("World!"));
setToolTipRecursively(panel, "Hello World!");
frame.add(panel, BorderLayout.CENTER);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 300);
frame.setVisible(true);
}
