Struct gtk4::ColorChooserWidget[][src]

pub struct ColorChooserWidget(_);
Expand description

The ColorChooserWidget widget lets the user select a color.

By default, the chooser presents a predefined palette of colors, plus a small number of settable custom colors. It is also possible to select a different color with the single-color editor.

To enter the single-color editing mode, use the context menu of any color of the palette, or use the ‘+’ button to add a new custom color.

The chooser automatically remembers the last selection, as well as custom colors.

To create a ColorChooserWidget, use new().

To change the initially selected color, use ColorChooserExt::set_rgba(). To get the selected color use ColorChooserExt::rgba().

The ColorChooserWidget is used in the ColorChooserDialog to provide a dialog for selecting colors.
