1) My program is a desktop applicaiton, not a web-site one (hovewer I am aware Qt can be scripted with a javascript-alike scripting engine, but I never used it and I don't know if this is the case);
2) The program you cited is not free, and this would be a problem for my gpl-program;
3) I already solved in the above way.

Thank you any how...
