pub struct ColorChooserWidget { /* private fields */ }
Expand description
Direct use of ColorChooserWidget
is deprecated.
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.
§Actions
ColorChooserWidget
defines a set of built-in actions:
color.customize
activates the color editor for the given color.color.select
emits thecolor-activated
signal for the given color.
§CSS names
ColorChooserWidget
has a single CSS node with name colorchooser.
§Properties
§show-editor
true
when the color chooser is showing the single-color editor.
It can be set to switch the color chooser into single-color editing mode.

in
the default signal handler.
Note that if both tooltip-text
and
tooltip-markup
are set, the last one wins.

When ::use-alpha is false
, the gdk::RGBA
struct obtained
via the rgba
property will be
forced to have alpha == 1.
