-
Window.
__init__
(**kwargs)[source]¶ Initialize a window instance.
Parameters: - title (str) – The window title
- gl_version (tuple) – Major and minor version of the opengl context to create
- size (tuple) – Window size x, y
- resizable (bool) – Should the window be resizable?
- fullscreen (bool) – Open window in fullsceeen mode
- vsync (bool) – Enable/disable vsync

-
Window.
is_key_pressed
(key) → bool¶ Returns: The press state of a key
-
Window.
close
() → None¶ Signal for the window to close
-
Window.
clear
(red=0.0, green=0.0, blue=0.0, alpha=0.0, depth=1.0, viewport=None)[source]¶ Binds and clears the default framebuffer
Parameters: - red (float) – color component
- green (float) – color component
- blue (float) – color component
- alpha (float) – alpha component
- depth (float) – depth value
- viewport (tuple) – The viewport
-
Window.
render
(time=0.0, frame_time=0.0) → None¶ Renders a frame by calling the configured render callback
Keyword Arguments: - time (float) – Current time in seconds
- frame_time (float) – Delta time from last frame in seconds
-
Window.
swap_buffers
() → None[source]¶ Placeholder. We currently don’t do double buffering in headless mode. This may change in the future.
-
Window.
resize
(width, height) → None¶ Should be called every time window is resized so the example can adapt to the new size if needed
-
Window.
set_default_viewport
() → None¶ Calculates the viewport based on the configured aspect ratio. Will add black borders and center the viewport if the window do not match the configured viewport.
If aspect ratio is None the viewport will be scaled to the entire window size regardless of size.
