java如何使用gquery手势插件在页面上启用文本突出显示？

Question

我有一个为移动设备设计的复杂GWT应用程序，在其（根）ApplicationPresenter中有以下gwtquery-gestures-plugin代码：

$(RootPanel.get())
            .as(Gesture.Gesture)
            .on("tap", new Function()
            {
                @Override
                public boolean f(Event e)
                {
                    Log.info("tap:" + e.getType() + ", x:" + e.getClientX() + ", y:" + e.getClientY());

                    // handle tap events here

                    return true;
                }
            })
            .on("swipeone", new Function()
            {
                @Override
                public boolean f(Event e)
                {
                    GestureObjects.Options o = arguments(0);
                    int delta = (int) o.delta().get(0).moved();

                    Log.info(o.description() + ":" + o.directionName() + ", x:" + e.getClientX() + ", y:" + e.getClientY() + ", delta:" + delta);

                    // handle swipe events here

                    return true;
                }

            });

不幸的是，这个插件似乎完全劫持了文本的本机选择，因此用户无法复制和粘贴任何内容。有没有办法实现这一点，或者有什么解决办法

在仔细检查文档后，我发现这个静态布尔值hasGestures，可以用来检查我们是否正在移动decive上加载

因此，代码段现在变成：

if(Gesture.hasGestures) // only load for mobile devices
    {
        $(RootPanel.get())
                .as(Gesture.Gesture)
                .on("tap", new Function() 
                {
                    @Override
                    public boolean f(Event e)
                    {
                        Log.info("tap:" + e.getType() + ", x:" + e.getClientX() + ", y:" + e.getClientY());

                        return true;
                    }
                })
                .on("swipeone", new Function()
                {
                    @Override
                    public boolean f(Event e)
                    {
                        GestureObjects.Options o = arguments(0);
                        int delta = (int) o.delta().get(0).moved();

                        Log.info(o.description() + ":" + o.directionName() + ", x:" + e.getClientX() + ", y:" + e.getClientY() + ", delta:" + delta);

                        return true;
                    }

                });
    }
    else
    {
        Log.info("Not adding gesture handlers as this is not a mobile device!");
    }
