Is a field editable?

[Horace Ho]

Hi,

  What can prohibit a field from accepting input from
graffiti or virtual keyboard other than the 'editable'
attribute?

  I have explicitly set a field's editable value to 1,
and verify with the following code:

  {
  FieldAttrType attr;
  FieldPtr fldP = FrmGetObjectPtr(frm, FrmGetObjectIndex(frm,
MainDesc1Field));
  if (fldP) {
    FldGetAttributes (fldP, &attr);
    if (attr.editable) WinDrawChars("Yes", 3, 1, 1);
    else WinDrawChars("No", 2, 1, 1);
  }

  However the field just does not accept any input
(no append/delete/insert).

  Why?

Thanks
