Required Methods
sourcefn title(&self) -> Option<GString>
fn title(&self) -> Option<GString>
Gets the title of the color selection dialog.
Returns
An internal string, do not free the return value
sourcefn set_alpha(&self, alpha: u32)
fn set_alpha(&self, alpha: u32)
The selected opacity value (0 fully transparent, 65535 fully opaque).
sourcefn shows_editor(&self) -> bool
fn shows_editor(&self) -> bool
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.
sourcefn set_show_editor(&self, show_editor: bool)
fn set_show_editor(&self, show_editor: bool)
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.
sourcefn connect_color_set<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
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.
