Expand description

Trait containing all ColorChooser methods.

§Implementors

ColorButton, ColorChooserDialog, ColorChooserWidget, ColorChooser

Provided Methods§

Source

fn rgba(&self) -> RGBA

Gets the currently-selected color.

§Returns
§color

a gdk::RGBA to fill in with the current color

Source

fn uses_alpha(&self) -> bool

Returns whether the color chooser shows the alpha channel.

§Returns

true if the color chooser uses the alpha channel, false if not

Source

fn set_rgba(&self, color: &RGBA)

Sets the color.

§color

the new color

Source

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

Source

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

Emitted when a color is activated from the color chooser. This usually happens when the user clicks a color swatch, or a color is selected and the user presses one of the keys Space, Shift+Space, Return or Enter.

§color

the color

Source

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

Source

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

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
