ColorChooserT.useAlpha

Set useAlpha property.

bool useAlpha [@property getter]
bool useAlpha [@property setter]
template ColorChooserT()
@property
void
useAlpha
(
bool propval
)

Parameters

propval bool: 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).

Detailed Description

Deprecated: Use gtk.color_dialog.ColorDialog and gtk.color_dialog_button.ColorDialogButton instead of widgets implementing gtk.color_chooser.ColorChooser
