◆ isEditable()

bool isEditable ( const ShaderInput & ) const

overridevirtual

Returns true if an input is editable by users.

Editable inputs are allowed to be published as shader uniforms and hence must be presentable in a user interface. By default all inputs are considered to be editable.

Reimplemented from ShaderNodeImpl.

The documentation for this class was generated from the following file:
