// NOTES FOR CREATING SUBPAGES
//===============================
// 1) Subclass this PageWidget for any client page
// 2) Init any internal widgets/classes in the constructor
// 3) Make sure you handle the [Save/Load]Settings functions (LoadSettings() will be called automatially after widget creation)
// 4) Make sure to emit the signals as needed for interactivity with the main container
//===============================

//Structure of all information needed for a page
struct PAGEINFO{
  QString name, title,  icon, comment, category, id;

	//emit this when we need to change to another client/page (if needed - generally only used for the base/group pages)
	void ChangePage(QString); //ID of new page to open
