Struct SymbolicPaintable

Source
pub struct SymbolicPaintable { /* private fields */ }
Available on crate feature v4_6 only.
Expand description

SymbolicPaintable is an interface that support symbolic colors in paintables.

gdk::Paintables implementing the interface will have the vfunc::Gtk::SymbolicPaintable::snapshot_symbolic function called and have the colors for drawing symbolic icons passed. At least 4 colors are guaranteed to be passed every time.

These 4 colors are the foreground color, and the colors to use for errors, warnings and success information in that order.

More colors may be added in the future.

§Implements

SymbolicPaintableExt, gdk::prelude::PaintableExt

GLib type: GObject with reference counted clone semantics.
