Implementations

Creates a new color button.

This returns a widget in the form of a small button containing a swatch representing the current selected color. When the button is clicked, a color chooser dialog will open, allowing the user to select a color. The swatch will be updated to reflect the new color when the user finishes.

Returns

a new color button

Creates a new color button showing the given color.

rgba

A gdk::RGBA to set the current color with

Returns

a new color button

Creates a new builder-pattern struct instance to construct ColorButton objects.

This method returns an instance of ColorButtonBuilder which can be used to create ColorButton objects.

Gets whether the dialog is modal.

Returns

true if the dialog is modal

Gets the title of the color chooser dialog.

Returns

An internal string, do not free the return value

Sets whether the dialog should be modal.

true to make the dialog modal

Sets the title for the color chooser dialog.

title

String containing new window title

Whether the color chooser should open in editor mode.

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.

Emitted when the user selects a color.

When handling this signal, use ColorChooserExt::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.
