this.add(widgetPanel); // add the component in an absolute position and size
Ok, now we start to migrate to new version, we have a top layer that hide the componentes, for example: Buttons extends SenchaButton so there is no problem to migrate the application. But the BIG problem are we can't find a similar way to position the componentes in Absolute position and size with GXT 3.0
¿Can you help us with this? We spent a lot of time finding a solution in Internet, but at the moment we fail.
