I put this into the class that creates the Frame. A mouse event in
the primary screen class (which extends AbsolutePanel and has this
object placed on it) calls 'offerControls()' - which will someday.
For now, it's just a quick re-use while I work this out.
It has no effect - the scrollbars are still there. I do see the
Window.Alert, so I know the call comes through:
public class Underlay extends Frame implements ftWidget
{
private String address = null;
private Underlay()
{}
public Underlay( String address )
{
this.address = address;
this.setUrl( address );
// this.setStylePrimaryName( ".ft-underlay" );
}
public void offerControls()
{
Window.alert( "Called offerControls" );
newPageInFrame( this.getElement() );
}
native void newPageInFrame( Element frame )/*-{
var FramePageHeight = framePage.scrollHeight + 10;
frame.style.height=FramePageHeight;
}-*/;
}
Any thoughts? If I make this Frame arbitrarily big, then there
(usually) won't be scrollbars, but the outer panel would scroll off
into space. I am bemused there is no way to tell this to size itself
to fit it's contents (what else is it for?).
I did some experiments with SmartGWT setAutoHeight() but couldn't get
the scrollbars to leave that way either. If you're certain that would
work, it's worth pursuing.
Any help would be appreciated.
Thanks,
Bret
