Thanks Aris. I am new to C++ GUI and upp.

I am lost on how to use the code you posted.

For a simple app re text only when enter key pushed (K_ENTER ?).
#include <CtrlLib/CtrlLib.h>

using namespace Upp;

GUI_APP_MAIN
{
	TopWindow  app;
	app.SetRect(0, 0, 200, 60);
	EditField  box1, box2;
	app.Add(box1.TopPosZ(0, 20).HSizePos());
	app.Add(box2.TopPosZ(20, 20).HSizePos());
	
	box2<<= ~box1;
//	box2<<= conv(~box1, units, decpl);
	
	app.Run();
}

Having the data typed into box1 go to box2 only when K_ENTER.

My upp Gui works good and converts angles decimal degrees to deg min sec, converts distance meters, km, feet, miles nautical miles, etc.
Calculate the geodesic distance with the Vincenty Formula/s. There are some situations where data typed in like miles it should be acted on by K_ENTER rather than and before a calculation function is called.
