Gl.PushName (gb.opengl)

Push and pop the name stack.

Parameters

name

Specifies a name that will be pushed onto the name stack.

Description

The name stack is used during selection mode to allow sets of rendering commands to be uniquely identified. It consists of an ordered set of unsigned integers and is initially empty.

Gl.PushName causes name to be pushed onto the name stack. Gl.PopName pops one name off the top of the stack.

The maximum name stack depth is implementation-dependent; call Gl.MAX_NAME_STACK_DEPTH to find out the value for a particular implementation. It is an error to push a name onto a full stack or to pop a name off an empty stack. It is also an error to manipulate the name stack between the execution of Gl.Begin and the corresponding execution of Gl.End. In any of these cases, the error flag is set and no other change is made to GL state.

The name stack is always empty while the render mode is not Gl.SELECT. Calls to Gl.PushName or Gl.PopName while the render mode is not Gl.SELECT are ignored.

Errors

Gl.STACK_OVERFLOW is generated if Gl.PushName is called while the name stack is full.

Gl.STACK_UNDERFLOW is generated if Gl.PopName is called while the name stack is empty.

Gl.INVALID_OPERATION is generated if Gl.PushName or Gl.PopName is executed between a call to Gl.Begin and the corresponding call to Gl.End.

Associated Gets
