JButton with HTML named action and a mnemonic
I have a JButton that is constructed using an Action and this action has a name that is contains html.
I then开发者_如何学Python go about setting the mnemonic on the JButton by first parsing out html to get the first character in the name.
For example, the JButton name might be "<html>Test<br>Button</html>", so after parsing the html the mnemonic key should be "T".
So now when the JButton is rendered I can push alt-T to activate the button, however the underline mnemonic indicator on the T is not present.
Would anyone know a way to get this to occur?
It is unclear to me what you mean by "setting the mnemomic on the JButton by parsing html". The mnemonic can be set on a JButton by calling the method setMnemonic in the JButton class. I tried below piece of code and when I press Alt+P I get the message I am pressed printed in the console.
public class HTMLButton extends JPanel implements ActionListener {
JButton b1;
public HTMLButton() {
super(new BorderLayout());
b1 = new JButton("<html><b><u>P</u>ress</b></html>");
b1.setMnemonic(KeyEvent.VK_P);
b1.addActionListener(this);
add(b1);
}
public void actionPerformed(final ActionEvent e) {
System.out.println("I am pressed");
}
}
