PointerInterface

public class ColorChooser
extends Interface

`GtkColorChooser` is an interface that is implemented by widgets
for choosing colors.

Depending on the situation, colors may be allowed to have alpha (translucency).

Method Details

getClassHandler

public static ClassHandler getClassHandler()

getRgba

public void getRgba(@Nonnull
 RGBA color)

Gets the currently-selected color.

Parameters:

color - a `GdkRGBA` to fill in with the current color

getUseAlpha

public boolean getUseAlpha()

Returns whether the color chooser shows the alpha channel.

Returns:

%TRUE if the color chooser uses the alpha channel, %FALSE if not

setRgba

public void setRgba(@Nonnull
 RGBA color)

Sets the color.

Parameters:

color - the new color

setUseAlpha

public void setUseAlpha(boolean use_alpha)

Sets whether or not the color chooser should use the alpha channel.

Parameters:

use_alpha - %TRUE if color chooser should use alpha channel, %FALSE if not

onColorActivated

public SignalHandler onColorActivated(ColorChooser.OnColorActivated signal)

Connect to signal "color-activated".
See ColorChooser.OnColorActivated.onColorActivated(ch.bailu.gtk.gdk.RGBA) for signal description.
