There is Virtual Method NewScrollPos() can be overloaded and which can then be used to call a callback WhenScrollChange. setting WhenScrollChange from main app can be used to trace scrollchange.
scrollclick can be implemented probably with a more elaborate derived class forwarding leftclick event of sb object member of LineEdit class.
#include <CtrlLib/CtrlLib.h>
using namespace Upp;
class LineEditExtended : public LineEdit{
public:
virtual void NewScrollPos(){ WhenScrollChange();}
Callback WhenScrollChange;
};
