In this article we will see how we can trigger on context state lost event in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). This event get triggered when the state of the window’s GL context was lost. pyglet may sometimes need to recreate the window’s GL context if the window is moved to another video device, or between fullscreen or windowed mode. In this case it will try to share the objects (display lists, texture objects, shaders) between the old and new contexts. If this is possible, only the current state of the GL context is lost, and the application should simply restore state.
We can create a window with the help of command given below
pyglet.window.Window(width, height, title)
Below is the syntax of the window on context state lost event, this method get called when this event is triggered
@window.event def on_context_state_lost(): print("Context State Lost")
Below is the implementation
