Re: Wait until widget is ready

Hi Michael,

The Widget.onLoad method should be called after its attached to the
document (rendered)...

Assuming that you have a "MyComponent" inside a ScrollPanel, perhaps
try this in your MyComponent:

@Override
public onLoad() {

Widget parent = getParent();

if (parent != null && parent.isAttached() && parent.isVisible
()) {
// set parent scrollPosition...
}
}

How are you calculating the scollPosition?

Cheers,
Dave
