When using a read-only EditString field right button menu "Copy" works, however Ctrl-C does not work.
Test case:
include <CtrlLib/CtrlLib.h>
using namespace Upp;
GUI_APP_MAIN
{
TopWindow app;
app.SetRect(0, 0, 200, 20);
EditString text;
text <<= "Try to copy this with Ctrl-C";
text.SetReadOnly();
app.Add(text.SizePos());
app.Run();
}
In this example you will not copy the field with Ctrl-C, only with right button menu and choosing "Copy".
