// Problem: how to add items to a tab?
// First off, widget should allow non-dialog bosses, (i.e. also other widgets)
// Could add a common base class for Widgets and Dialogs.
// Then you add tabs using the following method, which returns a unique ID
      int addTab(const String &title);
// Maybe we need to remove tabs again? Hm
      //void removeTab(int tabID);
// Setting the active tab:
      void setActiveTab(int tabID);
// setActiveTab changes the value of _firstWidget. This means Widgets added afterwards
// will be added to the active tab.
