Methods

PangoColor (Handle = null)

Creates a new Color by wrapping a native handle or another wrapper.
- @p Handle is the native handle or another wrapper whose handle to adopt.
toNativeHandle (Source)

Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.
- @p Source is the raw handle, raw buffer, wrapper, or null.
- @r A raw pointer carrier or null when no pointer is present.
getLib ()

Returns the opened native library for this generated wrapper.
- @r The opened native library.
handle ()

Returns the wrapped NativeHandle.
- @r The wrapped NativeHandle.
isNull ()

Returns true when the wrapped handle is null.
- @r A bool.
describe ()

Returns a small string for debugging generated wrappers.
- @r A string.
copy ()

Creates a copy of @src. The copy should be freed with [method@Pango.Color.free]. Primarily used by language bindings, not that useful otherwise (since colors can just be copied by assignment in C).
- @r the newly allocated PangoColor, which should be freed with [method@Pango.Color.free].
free ()

Frees a color allocated by [method@Pango.Color.copy].
- @r None.
parse (string spec)

Fill in the fields of a color from a string specification. The string can either one of a large set of standard names. (Taken from the CSS Color specification, or it can be a value in the form #rgb, #rrggbb, #rrrgggbbb or #rrrrggggbbbb, where r, g and b are hex digits of the red, green, and blue components of the color, respectively. (White in the four forms is #fff, #ffffff, #fffffffff and #ffffffffffff.)
- @p spec is a string specifying the new color.
- @r %TRUE if parsing of the specifier succeeded, otherwise %FALSE.
parse_with_alpha (string spec)

Fill in the fields of a color from a string specification. The string can either one of a large set of standard names. (Taken from the CSS Color specification, or it can be a hexadecimal value in the form #rgb, #rrggbb, #rrrgggbbb or #rrrrggggbbbb where r, g and b are hex digits of the red, green, and blue components of the color, respectively. (White in the four forms is #fff, #ffffff, #fffffffff and #ffffffffffff.) Additionally, parse strings of the form #rgba, #rrggbbaa, #rrrrggggbbbbaaaa, if
- @alpha is not %NULL, and set @alpha to the value specified by the hex digits for a. If no alpha component is found in @spec, @alpha is set to 0xffff (for a solid color).
- @p alpha is return location for alpha.
- @p spec is a string specifying the new color.
- @r %TRUE if parsing of the specifier succeeded, otherwise %FALSE.
to_string ()

Returns a textual specification of @color. The string is in the hexadecimal form #rrrrggggbbbb, where r, g and b are hex digits representing the red, green, and blue components respectively.
- @r a newly-allocated text string that must be freed with g_free()..

[12:14] static extends: object

Methods
