To populate a Tlist item, do the following:
1. Create a TLIST item in the EMP block. and give it a height to accommodate several names.
2. Using the TLIST property pallete:
a. Set the Column Name property to EMPNO
b. Click on the Elements in List property. Delete each List Element and delete each List Item Value. If you don't do this you will get an error when you compile.
3. Create a record group using this query:
select ename, to_char(empno) from emp
4. Create a WHEN-NEW-FORM-INSTANCE trigger, and place this code inside the trigger:
Declare
err_num number;
Begin
clear_list('YOUR_TLIST');
err_num := populate_group('YOUR_RECORD_GROUP');
If err_num = 0 Then
populate_list('YOUR_TLIST', 'YOUR_RECORD_GROUP');
Else
message('Error populating Tlist');
message('Error populating Tlist');
End If;
End;
5. Compile and run the form. The ENAMEs will appear in the TList, and each ENAME will have a value equal to its EMPNO.
