Methods

GskShaderArgsBuilder (shader = null, initial_values = null)

Allocates a builder that can be used to construct a new uniform data chunk.
- @p shader is a GskGLShader.
- @p initial_values is optional GBytes with initial values.
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.
free_to_args ()

Creates a new GBytes args from the current state of the given @builder, and frees the @builder instance. Any uniforms of the shader that have not been explicitly set on the @builder are zero-initialized.
- @r the newly allocated buffer with all the args added to @builder.
ref ()

Increases the reference count of a GskShaderArgsBuilder by one.
- @r the passed in GskShaderArgsBuilder.
set_bool (int idx, bool value)

Sets the value of the uniform @idx. The uniform must be of bool type.
- @p idx is index of the uniform.
- @p value is value to set the uniform to.
- @r None.
set_float (int idx, double value)

Sets the value of the uniform @idx. The uniform must be of float type.
- @p idx is index of the uniform.
- @p value is value to set the uniform to.
- @r None.
set_int (int idx, int value)

Sets the value of the uniform @idx. The uniform must be of int type.
- @p idx is index of the uniform.
- @p value is value to set the uniform to.
- @r None.
set_uint (int idx, int value)

Sets the value of the uniform @idx. The uniform must be of uint type.
- @p idx is index of the uniform.
- @p value is value to set the uniform to.
- @r None.
set_vec2 (int idx, object value)

Sets the value of the uniform @idx. The uniform must be of vec2 type.
- @p idx is index of the uniform.
- @p value is value to set the uniform too.
- @r None.
set_vec3 (int idx, object value)

Sets the value of the uniform @idx. The uniform must be of vec3 type.
- @p idx is index of the uniform.
- @p value is value to set the uniform too.
- @r None.
set_vec4 (int idx, object value)

Sets the value of the uniform @idx. The uniform must be of vec4 type.
- @p idx is index of the uniform.
- @p value is value to set the uniform too.
- @r None.
to_args ()

Creates a new GBytes args from the current state of the given @builder. Any uniforms of the shader that have not been explicitly set on the
- @builder are zero-initialized. The given GskShaderArgsBuilder is reset once this function returns; you cannot call this function multiple times on the same @builder instance. This function is intended primarily for bindings. C code should use [method@Gsk.ShaderArgsBuilder.free_to_args].
- @r the newly allocated buffer with all the args added to @builder.
unref ()

Decreases the reference count of a GskShaderArgBuilder by one. If the resulting reference count is zero, frees the builder.
- @r None.
