The KisFontComboBoxes class This is a little widget with two comboboxes. One is for the font family, and the other for the style, using the power of QFontDataBase. This allows us to limit the amount of fonts visible in the fonts drop down, as that can be a quite intense number when you have several 'style complete' fonts.
