REPLY FIELDS responsetype The type of this reply, in this case XCBQUERYFONT. This field is also present in the xcbgenericreplyt and can be used to tell replies apart from each other. sequence The sequence number of the last request processed by the X11 server. length The length of the reply, in words (a word is 4 bytes). minbounds minimum bounds over all existing char maxbounds maximum bounds over all existing char mincharorbyte2 first character maxcharorbyte2 last character defaultchar char to print for undefined character propertieslen how many properties there are drawdirection One of the following values: XCBFONTDRAWLEFTTORIGHT TODO: NOT YET DOCUMENTED. XCBFONTDRAWRIGHTTOLEFT TODO: NOT YET DOCUMENTED. minbyte1 TODO: NOT YET DOCUMENTED. maxbyte1 TODO: NOT YET DOCUMENTED. allcharsexist flag if all characters have nonzero size fontascent baseline to top edge of raster fontdescent baseline to bottom edge of raster charinfoslen TODO: NOT YET DOCUMENTED. DESCRIPTION Queries information associated with the font. RETURN VALUE Returns an xcbqueryfontcookiet. Errors have to be handled when calling the reply function xcbqueryfontreply. If you want to handle errors in the event loop instead, use xcbqueryfontunchecked. See xcb-requests(3) for details. ERRORS This request does never generate any errors. SEE ALSO
