Expand description
Required methods
Gets the title of the color selection dialog.
Returns
An internal string, do not free the return value
The selected opacity value (0 fully transparent, 65535 fully opaque).
fn shows_editor(&self) -> bool
fn shows_editor(&self) -> bool
v3_20
only.Set this property to true
to skip the palette
in the dialog and go directly to the color editor.
This property should be used in cases where the palette in the editor would be redundant, such as when the color button is already part of a palette.
fn set_show_editor(&self, show_editor: bool)

fn connect_color_set<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
The ::color-set signal is emitted when the user selects a color.
When handling this signal, use gtk_color_button_get_rgba()
to
find out which color was just selected.
Note that this signal is only emitted when the user changes the color. If you need to react to programmatic color changes as well, use the notify::color signal.
