[GuiLib] Member initialization issues, i.e.:
         - Member variable 'Foo::bar' is not initialized in the constructor.
         - Member variable 'Foo::bar' is in the wrong place in the initializer list.
         - Variable 'foo' is assigned in constructor body.
           Consider performing initialization in initialization list.
