InspectorBar with larger font and access to combobox itemindex

I´m using IspectorBar with a larger font. Where can I set the font size of the combobox of the valuelist property?

And is it possible to find out the itemindex of the combobox?

The font of the combobox is set to the font of the TInspectorPanel where the inplace combobox editor is on.
From where exactly do you want to get the ItemIndex of the combobox? Before?During?After? editing?
