void Xrb::GL::Initialize

(

)

Sets up a bunch of rendering parameters and so forth.

Screen calls this in Xrb::Screen::Create -- you shouldn't need to call it directly.

References Xrb::GLTexture::Create(), and Xrb::Texture::Data().

bool Xrb::GL::Boolean

(

GLenum

name

)

Convenience frontend to glGetBooleanv for getting a single value.

Only the first boolean value of a multi-valued property will be returned. Also, I lied about it being a frontend to glGetBooleanv. It's actually a frontend to GL::Integer.

GLint Xrb::GL::Integer

(

GLenum

name

)

Convenience frontend to glGetIntegerv for getting a single value.

Only the first integer value of a multi-valued property will be returned.

Definition at line 186 of file xrb_gl.cpp.

void Xrb::GL::SetClipRect

(

ScreenCoordRect const &

clip_rect

)

Used by Widget when setting the clipping planes and viewport.

Widget calls during Xrb::Widget::Draw -- you shouldn't need to call it directly.
