[SOLVED] Change the font of Gnome System Tray Notifications

[parsilinux]

Hi.
I need to change the font and its size, in gnome system tray notifications popup. (not libnotify)
for example i am using MDic Dictionary and when i highlight a word to see its translation, the font in notification popup is small and hard to read. (see the picture below):

tnx.
