Form Part access through scripting

Is it possible to get (limited) access through scripting to the properties of Form Parts?

for example: the heigth and the BackGroundColor?

Reason: In the footer of my form I have a ToolBar with buttons. Buttons can be dynamically added. So, it can be that there are so many buttons on the Toolbar that they do not fit nicely. In that case I want to show a second row ToolBar (Is always there, but normally invisible). For this, the height of the Footer needs to be adjustable, so I can both fit them into the Footer (normally, the footer has the height of only one ToolBar).

The height is not possible we will think about the bgcolor
