Constructor & Destructor Documentation
| VRS::GtkCanvas::GtkCanvas | ( | void | ) |
< Merger of GLCanvas and Gtk::GLArea
| virtual VRS::GtkCanvas::~GtkCanvas | ( | ) | [virtual] |
This canvas encapsulates a Gtk::GlExt widget and converts the incoming events to VRS events, passing them on to `Canvas'.
Member Function Documentation
| virtual void VRS::GtkCanvas::setSize | ( | unsigned int | width, | |
| unsigned int | height | |||
| ) | [virtual] |
| virtual unsigned int VRS::GtkCanvas::getWidth | ( | ) | const [virtual] |
| virtual unsigned int VRS::GtkCanvas::getHeight | ( | ) | const [virtual] |
| virtual int VRS::GtkCanvas::getProperties | ( | ) | const [virtual] |
Returns the OpenGL capabilities of the canvas. This method is not implemented currently!
Implements VRS::GLCanvas.
| virtual void VRS::GtkCanvas::makeContextCurrent | ( | ) | [virtual] |
Hook for subclasses, should make the correct rendering context current.
Since makeContextCurrent should be the first action in order to prepare a redisplay, it should use as least ressources as possible (e.g. the engine). The creation of the engine (and other ressources) can not be forced by this abstract base class, so there may be no engine when makeContextCurrent is called.
Reimplemented from VRS::Canvas.
| GtkWidget* VRS::GtkCanvas::gtkobj | ( | ) | const [inline] |
Used to get access to the GTK+ opengl rendering area.
| void VRS::GtkCanvas::initgl | ( | ) | [protected] |
| virtual void VRS::GtkCanvas::finishRedisplay | ( | ) | [protected, virtual] |
called after OpenGL redisplay
invokes Canvas::finishRedisplay and deactivates standard attributes for OpenGL rendering.
