From the whole batch of answers i have received i could assume that there is no solution to this problem.
You could also conclude from the lack of answers that nobody feels to make a working example of what you wanted to achieve. You (and others, of course) can increase the chance of someone looking into your problem by creating a complete and minimal example of what you tried. It is of course not a guarantee to an answer, but let's say the least thing that a person seeking help should do. It is absolutely no use to publish only a few lines in case of a problem. What the problem-solvers want is code that they can cut and paste to their editor and run it. Then they look at the output and then at the code and sometimes they know where the problem is. One thing that a problem-solver will not want to do is fill in the missing parts of posted code like in a high school exam. I don't try to be smart here, it is just the fact how the community works.
