open tcl script in GUI

Hello all
I created a graphical interface (piece of them in the picture below):

I am interested in the following questions:
1. How can I bind running a .tcl file to a button click? (see the fourth question)
2. How to change the font size on the background? (in HyperView)
*TitleFont('Arial', 1, 0, 12) do not work

3. While I work in HyperMesh, i have command.tcl, where all my operations are recorded. But in HyperView I don't find such file. Then I try to 'File- Save session - open it in notepad'. But it is not log file

Is there such a file to see the commands being invoked?

4. I'm try to change legend and notes in HyperView. After wrote a .tcl to 'legend file'
But it is don't work from button. And worked, if we choose in manual mode (as picture in this topic):
