JMenu和JPopupMenu的摆动鼠标单击事件 [英] Swing Mouse Click Event for JMenu and JPopupMenu
问题描述
我希望Eclipse在Swing的菜单和弹出菜单之外的鼠标单击具有行为.基本上，在Eclipse中，当您在菜单外按下鼠标时，菜单消失，并且鼠标按下事件会转发到您用鼠标单击的组件上.
I would like to have Eclipse behavior for mouse clicks outside menus and popup menus in Swing. Basically, in Eclipse, when you press the mouse OUTSIDE the menu, the menu disappears and the mouse press event is forwarded to the component on which you clicked with the mouse.
令人烦恼的是，Swing并没有这样做，而且我也找不到解决之道.
Irritatingly, Swing does not do this, and I can't find a way around it.
现在，即使使用Windows LAF，我也必须再次单击以获取该组件来注册鼠标单击.
Right now, even with Windows LAF, i have to click a second time to get the component to register the mouse click.
为了得到答复，只需在桌子上做
For the sake of the response just do it on a table
final JPopupMenu popupMenu = new JPopupMenu();
JMenuItem viewProfile = new JMenuItem("View Profile");
viewProfile.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
}
});
popupMenu.add(viewProfile);
table.setComponentPopupMenu(popupMenu);
这是一个测试代码.我认为向每个简单的组件添加鼠标侦听器并不方便，因此它们可以在弹出菜单之后注册鼠标单击.在下面的示例中，表格确实实现了它，但按钮没有实现.
here is a test code. I don't think it is convenient to add a mouse listener to every simple component so they can register mouse clicks after a popup menu. In the following example, the Table does implement it, but not the Button.
import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JMenuItem;
import javax.swing.JPanel;
import javax.swing.JPopupMenu;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
import javax.swing.table.DefaultTableModel;
public class TestMouse {
public static void main(String[] args) {
new TestMouse();
}
private JLabel counter;
private int count;
private JPanel northPanel;
private JButton clickMe;
public TestMouse() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
DefaultTableModel model = new DefaultTableModel(new Object[] { "A", "B", "B", "B", "B", "B", "B" }, 10);
JTable table = new JTable(model);
northPanel = new JPanel();
clickMe = new JButton("Button");
clickMe.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("clicked");
count++;
}
});
counter = new JLabel("0");
northPanel.add(counter);
northPanel.add(clickMe);
final JPopupMenu popupMenu = new JPopupMenu();
JMenuItem viewProfile = new JMenuItem("View Profile");
viewProfile.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
}
});
popupMenu.add(viewProfile);
table.setComponentPopupMenu(popupMenu);
table.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
System.out.println("clicked");
count++;
counter.setText(String.valueOf(count));
}
});
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(northPanel, BorderLayout.NORTH);
frame.add(new JScrollPane(table));
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
}
推荐答案
我似乎无法复制该问题.
I don't seem to be able to replicate the issue.
当我右键单击表格时，会出现弹出菜单，当我再次单击表格(以消除弹出窗口)时，会触发mouseClicked事件.
When I right click the table, the popup menu appears and when I click the table again (to dismiss the popup), the mouseClicked event is triggered.
注意将计数器放在北位置...
Note the counter in the north position...
