The explanation of Benoit is correct but I do also not understand it 100% for following reason.

I had same finding in the past, and if you search in the complete source code you 
can find those "ToolPanelContainer, FExpander, ToolPanel, Expander" in components
written in gambas. And that is exactly what I do not understand.
