pyqt-reactivity is a project that aims to provide basic reactivity module for PyQt widgets.
Install the latest version from PyPI:
pip install -U pyqt-reactivity
To use basic reactivity module, see the following example:
from pyqt_reactivity import Ref, computed, ref
# Create a reactive reference.
a = ref(1)
a.watch(lambda v: print("a updated:", v))
# Define a computed function that depends on the reactive reference.
def a_squared(a: Ref[float]) -> float:
return a.value**2
# Create a computed reference.
b = computed(a_squared, args=(a,))
b.watch(lambda v: print("b updated:", v))
# Update the reactive reference.
a.value = 2See more implementations on examples folder.
