Thanks Thomas. Much cleaner that way!
New code:
/**
* @return the number of modal popups currently showing
*/
public static int getNumPopupsShowing() {
int result = 0;
for (int i=0; i<RootPanel.get().getWidgetCount(); i++) {
Widget widget = RootPanel.get().getWidget(i);
if (widget instanceof PopupPanel
&& ((PopupPanel)widget).isShowing()
&& ((PopupPanel)widget).isModal()) {
result++;
}
}
return result;
}
I actually thought this wouldn't work when compiled, because I didn't know
how it would tell which div was a popup panel, but somehow it does! Go GWT!
