Constructor & Destructor Documentation

Inti::Gtk::GL::DrawingArea::DrawingArea (   )

Construct a new DrawingArea that can render Open-GL graphics. To make the drawing area Open-GL capable you must call set_gl_capability().

Inti::Gtk::GL::DrawingArea::DrawingArea (  const Gdk::GL::Config &  glconfig, bool  direct = true )

Construct a new Open-GL capable DrawingArea. Parameters: glconfig  A Gdk::GL::Config. direct  Whether rendering is to be done with a direct connection to the graphics system. This constructor prepares the drawing area for its use with OpenGL. No sharing of display lists and texture objects takes place when you call this constructor, and the render type is set to Gdk::GL::RGBA_TYPE.

Inti::Gtk::GL::DrawingArea::DrawingArea (  const Gdk::GL::Config &  glconfig, int  width, int  height, bool  direct = true )

Construct a new Open-GL capable DrawingArea with the specified width and height. Parameters: glconfig  A Gdk::GL::Config. width  The width to request. height  The height to request. direct  Whether rendering is to be done with a direct connection to the graphics system. This constructor prepares the drawing area for its use with OpenGL. No sharing of display lists and texture objects takes place when you call this constructor, and the render type is set to Gdk::GL::RGBA_TYPE.

Inti::Gtk::GL::DrawingArea::DrawingArea (  const Gdk::GL::Config &  glconfig, const Gdk::GL::Context &  share_list, bool  direct = true )

Construct a new Open-GL capable DrawingArea. Parameters: glconfig  A Gdk::GL::Config. share_list  The Gdk::GL::Context with which to share display lists and texture objects. direct  Whether rendering is to be done with a direct connection to the graphics system. This method prepares the widget for its use with OpenGL. The render type is set to Gdk::GL::RGBA_TYPE.

Inti::Gtk::GL::DrawingArea::DrawingArea (  const Gdk::GL::Config &  glconfig, const Gdk::GL::Context &  share_list, int  width, int  height, bool  direct = true )

Construct a new Open-GL capable DrawingArea. Parameters: glconfig  A Gdk::GL::Config. share_list  The Gdk::GL::Context with which to share display lists and texture objects. width  The width to request. height  The height to request. direct  Whether rendering is to be done with a direct connection to the graphics system. This method prepares the widget for its use with OpenGL. The render type is set to Gdk::GL::RGBA_TYPE.

Member Function Documentation

bool Inti::Gtk::GL::DrawingArea::gl_begin (   )

Delimits the begining of the OpenGL execution. Returns: true if it is successful, false otherwise. This is a convenience method that retrieves a pointer to the drawing area's drawable, and then calls Gdk::GL::Drawable::gl_begin().

void Inti::Gtk::GL::DrawingArea::gl_end (   )

Delimits the end of the OpenGL execution. This is a convenience method that retrieves a pointer to the drawing area's drawable, and then calls Gdk::GL::Drawable::gl_end().

bool Inti::Gtk::GL::DrawingArea::is_double_buffered (   )  const

Determines whether the drawable supports the double-buffered visual. Returns: true if the double-buffered visual is supported, false otherwise. This is a convenience method that retrieves a pointer to the drawing area's drawable, and then calls Gdk::GL::Drawable::is_double_buffered().

void Inti::Gtk::GL::DrawingArea::swap_buffers (   )

Exchange the front and back buffers. This is a convenience method that retrieves a pointer to the drawing area's drawable, and then calls Gdk::GL::Drawable::swap_buffers().
