GWT通知小部件？ [英] GWT notification widget?

问题描述

你知道GWT是否有任何通知部件，比如这里的一个？

解决方案

  public class DelayedPopup extends PopupPanel {
 
 public DelayedPopup（String text，boolean autoHide，boolean modal）{
 super（autoHide，modal）; 
 setWidget（new Label（text））; 
} 
 
 void show（int delayMilliseconds）{
 show（）; 
 Timer t = new Timer（）{
 @Override 
 public void run（）{
 DelayedPopup.this.hide（）; 
} 
}; 
 
 //安排定时器在3秒内关闭弹出窗口。 
 t.schedule（3000）; 
 
 
 
 
 
 
 $ b 
这不在我的脑中，所以它可能不会编译，但你明白了。
 
 
 
 更新： 
 
 
 
 
  public class Notification extends PopupPanel {
 
 public Notification（String text）{
 super（false，false）; 
 setWidget（new Label（text））; 
} 
 
 @Override 
 public void show（）{
 installCloseHandler（）; 
 super.show（）; 
} 
 
 public native void installCloseHandler（）/ *  -  {
 var tmp = this; 
 $ wnd.onmousemove = function（）{
 //编辑com.google.gwt.sample.contacts.client包
 //与您自己的包名称匹配
 tmp @ com.google.gwt.sample.contacts.client.Notification ::隐藏（）（）; 
 $ wnd.onmousemove = null; 
} 
}  -  * /; 
} 
  
 
do you know if there is any notification widget for GWT out there, like this one here?

解决方案
AFAIK there is no such widget in core GWT, but why not roll your own: 
public class DelayedPopup extends PopupPanel {

    public DelayedPopup(String text, boolean autoHide, boolean modal) {
        super(autoHide, modal);
        setWidget(new Label(text));
    }

    void show(int delayMilliseconds) {
        show();
        Timer t = new Timer() {
            @Override
            public void run() {
                DelayedPopup.this.hide();
            }
        };

        // Schedule the timer to close the popup in 3 seconds.
        t.schedule(3000);
    }
}
This is out of my head so it might not compile, but you get the idea.

Update:

As per comment, I'm adding notification that hides itself on mouse move:
public class Notification extends PopupPanel {

    public Notification(String text) {
        super(false, false);
        setWidget(new Label(text));
    }

    @Override
    public void show() {
        installCloseHandler();
        super.show();
    }

    public native void installCloseHandler() /*-{
        var tmp = this;
        $wnd.onmousemove = function() {
            // edit the com.google.gwt.sample.contacts.client package 
            // to match your own package name
            [e-mail]::hide()();
            $wnd.onmousemove = null;
        }
    }-*/;
}
