下面代码实现了鼠标各按键单击和左键击双击，以及右键弹出菜单
JButton btn = new JButton("鼠标左键、右键、滚轮点击测试");
btn.addMouseListener(new MouseAdapter() {
@Override
public void mousePressed(MouseEvent e) {
if (e.getButton() == MouseEvent.BUTTON1) {
JOptionPane.showMessageDialog(MainFrame.this, "鼠标左键");
} else if (e.getButton() == MouseEvent.BUTTON2) {
JOptionPane.showMessageDialog(MainFrame.this, "鼠标滚轮点击");
} else if (e.getButton() == MouseEvent.BUTTON3) {
JOptionPane.showMessageDialog(MainFrame.this, "鼠标右键");
}
super.mousePressed(e);
}
});
JButton btn2 = new JButton("鼠标单击双击测试");
btn2.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
if (e.getButton() == MouseEvent.BUTTON1
&& e.getClickCount() == 2) {
JOptionPane.showMessageDialog(MainFrame.this, "鼠标双击");
}
super.mousePressed(e);
}
});
JButton btn3 = new JButton("右键弹出菜单");
btn3.addMouseListener(new MouseAdapter() {
@Override
public void mousePressed(MouseEvent event) {
// 调用triggerEvent方法处理事件
//triggerEvent(event);
// isPopupTrigger():返回此鼠标事件是否为该平台的弹出菜单触发事件。
if (event.isPopupTrigger())
// 显示菜单
popupMenu.show(event.getComponent(), event.getX(), event.getY());
}
@Override
public void mouseReleased(MouseEvent event) {
//triggerEvent(event);
// isPopupTrigger():返回此鼠标事件是否为该平台的弹出菜单触发事件。
if (event.isPopupTrigger())
// 显示菜单
popupMenu.show(event.getComponent(), event.getX(), event.getY());
}
});
