(Friendly bump)
Could anybody please tell me what i am doing wrong when i dynamically
change the contents of a fixed combobox?
The way i do it, every time the entries are new created, the combobox
displays each entry with "echos" - instead of showing the line "a1" it
shows the line "a1 a1". After the next time the contents are created,
each line shows s double echo (e.g., "s1 s1 s1" instead of "s1")
But when i read the contents of a selected entry, the value is correct:
it yields "a1" instead of the displayed "a1 a1 a1".
The attached zip file contains the sources and a makefile for
a very simplified application which shows the bad behaviour.
I would be very thankful for any helpful ideas
Thank You
Jody
