Hi, Pete.
Thanks for your advice.
I'd read the documents in the Matchbox site.
To change fonts for matchbox-panel, I must write '.desktop' file which have *same* name as *Matchbox-WM* theme. But, pdaXrom use the Openbox for WM. I have no idea to give a name to a .desktop file. In this case, I should use a default theme name? What is the default?
Is there a anybody who knows how to change fonts in this case.
