button.setText("Go");
button.addListener(SWT.Selection, new Listener(){
@Override
public void handleEvent(Event arg0) {
while (true) {
int x = MouseInfo.getPointerInfo().getLocation().x;
int y = MouseInfo.getPointerInfo().getLocation().y;
label.setText(x + ":" + y);
}

label = new Label(shell, SWT.NONE);
shell.open();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}
我有我想要的。
谢谢巴兹的帮助

您首先要实现的是什么?我想单击位于外部应用程序上的指定文本框,然后单击循环。我想记住单击的文本框位置x,y。如何知道外部应用程序中的文本框何时被单击?我不需要知道文本框何时被单击。我需要知道鼠标按钮是否被点击,无论它在哪里被点击。所以你只想知道你的按钮何时被点击?这就是SWT.Selection侦听器已经做的事情,那么为什么要使用while-true循环呢?
