The default "Lucida Grande" available on MacOS X has no italic variant. To confirm this look for Lucida Grande in Font Book or write "TEST" in TextEdit, set its font to Lucida Grande and try to make it Italic. If you want to use SLANT_ITALIC, you need a font which actually has an italic shape. (Please notice that some fonts have oblique style instead of italic and the quartz font backend considers them to be different). Thanks for reply, whether it is possible to check up presence of the necessary font somehow?
cairo_select_font_face(
target,
"Lucida Grande", // Default font on mac
CAIRO_FONT_SLANT_ITALIC,
CAIRO_FONT_WEIGHT_NORMAL );
cairo_status_t status = cairo_status( mpTarget );
// Here status == CAIRO_STATUS_SUCCESS

Cairo does its best to provide a font that looks like the one you asked for, but will fallback to less and less similar fonts, ending with "Helvetica" (normal) if it can't find what you were asking for. If you want to make sure the font will be the one you specified, you should probably use CGFontCreateWithFontName to create the CGFont and cairo_quartz_font_face_create_for_cgfont to use it within cairo.
