int gp_widget_tattr_parse(const char *attrs, gp_widget_tattr *tattr, int flags);
Text Attributes
Text attributes describe text font, size, etc. Attributes can be either passed
down as a C constants, e.g. GP_TATTR_BOLD | GP_TATTR_LARGE or parsed from a
string from JSON e.g. "bold|large".
Functions
Parses text attribute string, returns zero on success.
The flags can be used to select which attributes should be enabled in the parser. Passing GP_TATTR_FONT enables font parsing and GP_TATTR_HALIGN enables horizontal alignment flags, both can be enabled by passing a bitwise or i.e. GP_TATTR_FONT | GP_TATTR_HALIGN.
const gp_text_style *gp_widget_tattr_font(gp_widget_tattr attr, const gp_widget_render_ctx *ctx)
Returns a font based on the attributes and render context, this is supposed to be used in widgets for size computation and rendering.
