If I understand you correctly, you'd like to have a glasspanel above
the "previous activity" while the "new one" starts? (until it calls
AcceptsOneWidget#setWidget to "reveal" itself) ?
IMO you should do this on your AcceptsOneWidget itself, not from
within your activities:
final SimplePanel realDisplay = new SimplePanel();
myActivitymanager.setDisplay(new AcceptsOneWidget {
public void setWidget(IsWidget w) {
if (w == null) {
// show a glass panel
} else {
// hide the glass panel, then:
realDisplay.setWidget(x);
}
}
});
