I have a complex GWT application that is designed for mobile and has this gwtquery-gestures-plugin code in its (root) ApplicationPresenter:
$(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;
}
});
Unfortunately this plugin seems to totally hijack the native selection of text, so the user can't copy and paste anything. Is there a way to enable this, or a workaround of some kind?
On closer inspection of the documentation, I found this static boolean hasGestures that can be used to check if we are loading on a mobile decive or not.
So the snippet now becomes:
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!");
}
