Detailed Description

Rendering interfacing bridge between libRocket and nomlib.

Note: Currently, only the OpenGL back-end for SDL2 is supported.

Todo: Add support for OpenGLES and OpenGLES2 (mobile platforms).

Member Function Documentation

◆ gl_init()

bool nom::RocketSDL2RenderInterface::gl_init	(	int	width,
		int	height )

static

Initialize OpenGL with the necessary settings for libRocket and SDL2 to be all friendly.

Returns: Boolean TRUE if OpenGL initialization is successful, and boolean FALSE on failure.

Parameters

width	The width of the clipping plane (orthographic matrix).
height	The height of the clipping plane (orthographic matrix).

Note: This method should be called before the construction of this object, after the creation of a RenderWindow, and before any other rendering (OpenGL or otherwise).

Remarks: This is not part of the libRocket interface, and is provided as part of nomlib's high-level initialization routines.

◆ Release()

virtual void nom::RocketSDL2RenderInterface::Release ( )

virtual

Implements Rocket::Core::SystemInterface::Release.

Remarks: Called when this file interface is released.

◆ SetScissorRegion()

virtual void nom::RocketSDL2RenderInterface::SetScissorRegion	(	int	x,
		int	y,
		int	width,
		int	height )

virtual

Called by Rocket when it wants to change the scissor region.

Todo: The clipping calculations are slightly off for the y / height dimensions. This bug can often be seen with use of libRocket's scrollbar feature (i.e.: visual debugger's element info window).

Member Data Documentation

◆ ctx_

priv::glUseProgramObjectARB_func nom::RocketSDL2RenderInterface::ctx_

staticprivate

Shader context function pointer.

Note: We bypass the use of GLEW by requesting this extension through SDL2.

Definition at line 127 of file RocketSDL2RenderInterface.hpp.

◆ window_

RenderWindow* nom::RocketSDL2RenderInterface::window_

nomlib interface bridge between SDL2 and libRocket

Remarks: The interface does not own the pointer.
