Methods / Constructors
Method / Constructor		Defined By
	new Gdk.Visual () Create a new Gdk.Visual Create a new Gdk.Visual
	Gdk.Visual.get_best () : Gdk.Visual Get the visual with the most available colors for the default GDK screen. Get the visual with the most available colors for the default GDK screen. The return value should not be freed. Returns: Gdk.Visual best visual	Gdk.Visual
	Gdk.Visual.get_best_depth () : gint32 Get the best available depth for the default GDK screen. Get the best available depth for the default GDK screen. "Best" means "largest," i.e. 32 preferred over 24 preferred over 8 bits per pixel. Returns: gint32 best available depth	Gdk.Visual
	Gdk.Visual.get_best_type () : Gdk.VisualType Return the best available visual type for the default GDK screen. Return the best available visual type for the default GDK screen. Returns: Gdk.VisualType best visual type	Gdk.Visual
	Gdk.Visual.get_best_with_both (gint32 *depth, VisualType visual_type) : Gdk.Visual Combines gdk_visual_get_best_with_depth() and gdk_visual_get_best_with_type(). Combines gdk_visual_get_best_with_depth() and gdk_visual_get_best_with_type(). Parameters: gint32 depth* Required (not null) a bit depth Gdk.VisualType visual_type Required (not null) a visual type Returns: Gdk.Visual best visual with both depth and	Gdk.Visual
	Gdk.Visual.get_best_with_depth (gint32 *depth) : Gdk.Visual Get the best visual with depth depth* for the default GDK screen. Get the best visual with depth depth for the default GDK screen. Color visuals and visuals with mutable colormaps are preferred over grayscale or fixed-colormap visuals. The return value should not be freed. NULL may be returned if no visual supports depth. Parameters: gint32 depth Required (not null) a bit depth Returns: Gdk.Visual best visual for the given depth	Gdk.Visual
	Gdk.Visual.get_best_with_type (VisualType *visual_type) : Gdk.Visual Get the best visual of the given visual_type* for the default GDK screen. Get the best visual of the given visual_type for the default GDK screen. Visuals with higher color depths are considered better. The return value should not be freed. NULL may be returned if no visual has type Parameters: Gdk.VisualType visual_type Required (not null) a visual type Returns: Gdk.Visual best visual of the given type	Gdk.Visual
	Gdk.Visual.get_system () : Gdk.Visual Get the system's default visual for the default GDK screen. Get the system's default visual for the default GDK screen. This is the visual for the root window of the display. The return value should not be freed. Returns: Gdk.Visual system visual	Gdk.Visual
	get_bits_per_rgb () : gint32 Returns the number of significant bits per red, green and blue value. Returns the number of significant bits per red, green and blue value. Returns: gint32 The number of significant bits per color value for visual.	Gdk.Visual
	get_blue_pixel_details () : Object Obtains values that are needed to calculate blue pixel values in TrueColor and DirectColor. Obtains values that are needed to calculate blue pixel values in TrueColor and DirectColor. The "mask" is the significant bits within the pixel. The "shift" is the number of bits left we must shift a primary for it to be in position (according to the "mask"). Finally, "precision" refers to how much precision the pixel value contains for a particular primary. Returns: mask: guint32 shift: gint32 precision: gint32	Gdk.Visual
	get_byte_order () : Gdk.ByteOrder Returns the byte order of this visual. Returns the byte order of this visual. Returns: Gdk.ByteOrder A GdkByteOrder stating the byte order of visual.	Gdk.Visual
	get_colormap_size () : gint32 Returns the size of a colormap for this visual. Returns the size of a colormap for this visual. Returns: gint32 The size of a colormap that is suitable for visual.	Gdk.Visual
	get_depth () : gint32 Returns the bit depth of this visual. Returns the bit depth of this visual. Returns: gint32 The bit depth of this visual.	Gdk.Visual
	get_green_pixel_details () : Object Obtains values that are needed to calculate green pixel values in TrueColor and DirectColor. Obtains values that are needed to calculate green pixel values in TrueColor and DirectColor. The "mask" is the significant bits within the pixel. The "shift" is the number of bits left we must shift a primary for it to be in position (according to the "mask"). Finally, "precision" refers to how much precision the pixel value contains for a particular primary. Returns: mask: guint32 shift: gint32 precision: gint32	Gdk.Visual
	get_red_pixel_details () : Object Obtains values that are needed to calculate red pixel values in TrueColor and DirectColor. Obtains values that are needed to calculate red pixel values in TrueColor and DirectColor. The "mask" is the significant bits within the pixel. The "shift" is the number of bits left we must shift a primary for it to be in position (according to the "mask"). Finally, "precision" refers to how much precision the pixel value contains for a particular primary. Returns: mask: guint32 shift: gint32 precision: gint32	Gdk.Visual
	get_screen () : Gdk.Screen Gets the screen to which this visual belongs Gets the screen to which this visual belongs Returns: Gdk.Screen the screen to which this visual belongs.	Gdk.Visual
	get_visual_type () : Gdk.VisualType Returns the type of visual this is (PseudoColor, TrueColor, etc). Returns the type of visual this is (PseudoColor, TrueColor, etc). Returns: Gdk.VisualType A GdkVisualType stating the type of visual.	Gdk.Visual
