在Java中,可以通过添加WindowListener来捕获窗口最小化(windowIconified)和窗口恢复(windowDeiconified)事件。具体步骤如下:
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;
public class MyWindowListener implements WindowListener {
@Override
public void windowOpened(WindowEvent e) {
// 窗口打开时的操作
}
@Override
public void windowClosing(WindowEvent e) {
// 窗口关闭时的操作
}
@Override
public void windowClosed(WindowEvent e) {
// 窗口已经关闭时的操作
}
@Override
public void windowIconified(WindowEvent e) {
// 窗口最小化时的操作
}
@Override
public void windowDeiconified(WindowEvent e) {
// 窗口恢复时的操作
}
@Override
public void windowActivated(WindowEvent e) {
// 窗口被激活时的操作
}
@Override
public void windowDeactivated(WindowEvent e) {
// 窗口失去焦点时的操作
}
}
import javax.swing.JFrame;
public class MyFrame extends JFrame {
public MyFrame() {
// 设置窗口属性等
// ...
// 创建一个WindowListener对象
MyWindowListener windowListener = new MyWindowListener();
// 添加WindowListener到窗口对象
addWindowListener(windowListener);
}
}
public void updateUiChanged() {
// 其他操作
// 调用窗口对象的windowIconified()和windowDeiconified()方法
myFrame.windowIconified(new WindowEvent(myFrame, WindowEvent.WINDOW_ICONIFIED));
myFrame.windowDeiconified(new WindowEvent(myFrame, WindowEvent.WINDOW_DEICONIFIED));
// 其他操作
}
通过上述步骤,你可以在updateUiChanged()事件之前捕获Java窗口最小化和窗口恢复事件。
