Java MouseListener并非始终有效

Question

I find it odd that in my project, the mouselistener is not always heard. Has anyone else come across this? Or am I doing something wrong? I have to sometimes click it several times before it opens. I do wait between clicks to see if it is a performance issue.

JButton btnPin = new JButton("Pin");
btnPin.addMouseListener(new MouseAdapter() {
    public void mouseClicked(MouseEvent arg0) {
        if(staffPinDialog == null || staffPinDialog.isShowing() == false)
            staffPinDialog = new StaffPinDialog(idClicked);                 
    }
});

StaffPinDialog is a JDialog, where the reference has been created elsewhere. idClicked is also always initialized.

You're not supposed to use a MouseListener to detect button clicks. Use an ActionListener instead.

This will also have the additional advantage of being able to click the button using the keyboard.
