the new color

fn set_use_alpha(&self, use_alpha: bool)

Sets whether or not the color chooser should use the alpha channel.

use_alpha

true if color chooser should use alpha channel, false if not

fn connect_color_activated<F: Fn(&Self, &RGBA) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

color

the color

fn connect_property_rgba_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId
