Constants

Functions

GetBest() : Gtk.Gdk.Visual.T

Get the visual with the most available colors for the default GDK screen. The return value should not be freed.

Returns

best visual. [transfer none]

GetBestDepth() : Std.Integer.SmallT

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

best available depth

GetBestType() : Gtk.Gdk.VisualType.T

Return the best available visual type for the default GDK screen.

Returns

best visual type

GetBestWithBoth(depth @ Std.Integer.SmallT, visual_type @ Gtk.Gdk.VisualType.T) : Gtk.Gdk.Visual.T

Combines GetBestWithDepth and GetBestWithType.

depth	a bit depth
visual_type	a visual type
Returns	best visual with both depth and visual_type, or NULL if none. [transfer none]

GetBestWithDepth(depth @ Std.Integer.SmallT) : Gtk.Gdk.Visual.T

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.

depth	a bit depth
Returns	best visual for the given depth. [transfer none]

GetBestWithType(visual_type @ Gtk.Gdk.VisualType.T) : Gtk.Gdk.Visual.T

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 visual_type.

visual_type	a visual type
Returns	best visual of the given type. [transfer none]

GetSystem() : Gtk.Gdk.Visual.T

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

system visual. [transfer none]

GetType() : Gtk.GObject.Type.T

Methods

:GetBitsPerRgb(self @ T) : Std.Integer.SmallT

Returns the number of significant bits per red, green and blue value.

visual	a T
Returns	The number of significant bits per color value for visual.

:GetBluePixelDetails(self @ T, mask @ Std.Object.T, shift @ Std.Object.T, precision @ Std.Object.T) : Std.Object.T

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.

visual	a T
mask	A pointer to a guint32 to be filled in, or NULL. [out][allow-none]
shift	A pointer to a gint to be filled in, or NULL. [out][allow-none]
precision	A pointer to a gint to be filled in, or NULL. [out][allow-none]

:GetByteOrder(self @ T) : Gtk.Gdk.ByteOrder.T

Returns the byte order of this visual.

visual	A T.
Returns	A Gtk.Gdk.ByteOrder.T stating the byte order of visual.

:GetColormapSize(self @ T) : Std.Integer.SmallT

Returns the size of a colormap for this visual.

visual	A T.
Returns	The size of a colormap that is suitable for visual.

:GetDepth(self @ T) : Std.Integer.SmallT

Returns the bit depth of this visual.

visual	A T.
Returns	The bit depth of this visual.

:GetGreenPixelDetails(self @ T, mask @ Std.Object.T, shift @ Std.Object.T, precision @ Std.Object.T) : Std.Object.T

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.

visual	a T
mask	A pointer to a guint32 to be filled in, or NULL. [out][allow-none]
shift	A pointer to a gint to be filled in, or NULL. [out][allow-none]
precision	A pointer to a gint to be filled in, or NULL. [out][allow-none]

:GetRedPixelDetails(self @ T, mask @ Std.Object.T, shift @ Std.Object.T, precision @ Std.Object.T) : Std.Object.T

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.

visual	A T.
mask	A pointer to a guint32 to be filled in, or NULL. [out][allow-none]
shift	A pointer to a gint to be filled in, or NULL. [out][allow-none]
precision	A pointer to a gint to be filled in, or NULL. [out][allow-none]

:GetScreen(self @ T) : Gtk.Gdk.Screen.T

Gets the screen to which this visual belongs

visual	a T
Returns	the screen to which this visual belongs. [transfer none]

:GetVisualType(self @ T) : Gtk.Gdk.VisualType.T

Returns the type of visual this is (PseudoColor, TrueColor, etc).

visual	A T.
Returns	A Gtk.Gdk.VisualType.T stating the type of visual.
