如何使用gquery手勢插件在頁面上啟用文本突出顯示?

[英]How to enable text highlighting on a page using gquery gestures plugin?

我有一個專為移動設備設計的復雜GWT應用程序,其(根)ApplicationPresenter中具有以下gwtquery-gestures-plugin代碼:

$(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,此插件似乎完全劫持了文本的本機選擇,因此用戶無法復制和粘貼任何內容 有沒有一種方法可以啟用此功能,或者有某種解決方法?

在仔細檢查文檔時,我發現此靜態布爾hasGestures可用於檢查我們是否在移動設備上加載。

現在,代碼段變為:

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!");
    }
