ColorChooserGidBuilderImpl.useAlpha

T useAlpha(bool propval)

Set useAlpha property.

Parameters

propval Whether colors may have alpha (translucency). When ::use-alpha is false, the [gdk.rgba.RGBA] struct obtained via the [gtk.color_chooser.ColorChooser.rgba] property will be forced to have alpha == 1. Implementations are expected to show alpha by rendering the color over a non-uniform background (like a checkerboard pattern).

Returns

Builder instance for fluent chaining

Deprecated

Use [gtk.color_dialog.ColorDialog] and [gtk.color_dialog_button.ColorDialogButton]

instead of widgets implementing [gtk.color_chooser.ColorChooser]
