Dymically determing the number of check list in Zenity, How?

hi,
In my project i cannot determine the number of check list initially... I will know dynamically during execution... so How to specify the number of check list dynamically in zenity

Waiting for your precious Answer.....

You can count it on fly and then pass those options to zenity to a load dialog box or whatever. If you have working or pseudo code to show paste it here or explain in more detail.
