Java 如何使用gquery手势插件在页面上启用文本突出显示?
我有一个为移动设备设计的复杂GWT应用程序,其(根)ApplicationPresenter中有以下代码:Java 如何使用gquery手势插件在页面上启用文本突出显示?,java,gwt,gesture,gwtquery,gquery,Java,Gwt,Gesture,Gwtquery,Gquery,我有一个为移动设备设计的复杂GWT应用程序,其(根)ApplicationPresenter中有以下代码: $(RootPanel.get()) .as(Gesture.Gesture) .on("tap", new Function() { @Override public boolean f(Event e) {
$(RootPanel.get())
.as(Gesture.Gesture)
.on("tap", new Function()
{
@Override

{
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。是否有办法启用此功能,或者某种解决方法?仔细查看文档后,我发现这个静态布尔值

,可用于检查我们是否在移动设备上加载
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!");
}
