I'm creating a tablebox with a number col edit box that will show the date. However even if I set the format properly the calendar icon doesn't show up. Here's an example:
nw = new window("Test Calendar",
neb = number edit box(),
tb = table box(
string col box("String", {"One", "Two"}),
date_nceb = number col edit box("Dates", {., .})
)
);
neb << Set Format( Format( "ddMonyyyy", 12 ) );
date_nceb << Set Format( Format( "ddMonyyyy", 12 ) );

As you can see for the number edit box the calendar icon shows up properly. Nothing for the Dates column though.
