data Size
A 2-dimensional size, measured in pixels.
Examining and modifying the window
data GettableStateVar a
A concrete implementation of a read-only state variable, carrying an IO action to read the value.
Instances
data SettableStateVar a
A concrete implementation of a write-only state variable, carrying an IO action to write the new value.
Instances
Drawing the scene
data VertexProp t Source
Instances
clearScreen :: IO ()Source
swapBuffers :: IO ()
Swap the back and front color buffers of the window. If AutoPollEvent is
enabled by enableSpecial (which is the default), it also polls for new
events before the swapping.
