Member Function Documentation

void gui::gl::manager::begin

(

utils::refptr< gui::render_target >

pTarget = nullptr

)

const

Begins rendering on a particular render target.

Parameters:

pTarget

The render target (main screen if nullptr)

Definition at line 30 of file gui_gl_manager.cpp.

utils::refptr< gui::font > gui::gl::manager::create_font	(	const std::string &	sFontFile,
		uint	uiSize
	)			const [virtual]

Creates a new font.

Parameters:

	sFontFile	The file from which to read the font
	uiSize	The requested size of the characters (in points)

Note:

This implementation uses FreeType to load vector fonts and rasterize them. Bitmap fonts are not yet supported.

Implements gui::manager_impl.

Definition at line 206 of file gui_gl_manager.cpp.

utils::refptr< gui::material > gui::gl::manager::create_material

(

utils::refptr< gui::render_target >

pRenderTarget

)

const

Creates a new material from a render target.

Parameters:

pRenderTarget

The render target from which to read the pixels

Returns:

The new material

Definition at line 196 of file gui_gl_manager.cpp.

utils::refptr< gui::material > gui::gl::manager::create_material

(

const color &

mColor

)

const [virtual]

Creates a new material from a plain color.

Parameters:

mColor

The color to use

Returns:

The new material

Implements gui::manager_impl.

Definition at line 191 of file gui_gl_manager.cpp.

utils::refptr< gui::material > gui::gl::manager::create_material

(

const std::string &

sFileName

)

const [virtual]

Creates a new material from a texture file.

Parameters:

sFileName

The name of the file

Returns:

The new material

Note:

Only PNG textures are supported by this implementation (parsed by libpng).

Implements gui::manager_impl.

Definition at line 170 of file gui_gl_manager.cpp.

utils::refptr< gui::render_target > gui::gl::manager::create_render_target	(	uint	uiWidth,
		uint	uiHeight
	)			const [virtual]

Creates a new render target.

Parameters:

	uiWidth	The width of the render target
	uiHeight	The height of the render target

Implements gui::manager_impl.

Definition at line 201 of file gui_gl_manager.cpp.

void gui::gl::manager::end

(

)

const [virtual]

Ends rendering.

Implements gui::manager_impl.

Definition at line 73 of file gui_gl_manager.cpp.

bool gui::gl::manager::is_gl_extension_supported

(

const std::string &

sExtension

)

[static]

Checks if a given OpenGL extension is supported by the machine.

Returns:

'true' if that is the case, 'false' else.

Definition at line 223 of file gui_gl_manager.cpp.

void gui::gl::manager::render_quad

(

const quad &

mQuad

)

const [virtual]

Renders a quad.

Parameters:

mQuad

The quad to render on the current render target

Note:

This function is meant to be called between begin() and end() only.

Implements gui::manager_impl.

Definition at line 82 of file gui_gl_manager.cpp.

void gui::gl::manager::render_quads	(	const quad &	mQuad,
		const std::vector< std::array< vertex, 4 >> &	lQuadList
	)			const [virtual]

Renders a set of quads.

Parameters:

	mQuad	The base quad to use for rendering (material, blending, ...)
	lQuadList	The list of the quads you want to render

Note:

This function is meant to be called between begin() and end() only. It is always more efficient to call this method than calling render_quad repeatedly, as it allows to batch count reduction.

Implements gui::manager_impl.
