from qtpy.QtCore import Qt
from qtpy.QtWidgets import QApplication
from qtpy.QtWidgets import QGridLayout
from qtpy.QtWidgets import QWidget
from qtpy_led import Led
import numpy as np
import sys


class Demo(QWidget):
    def __init__(self, parent=None):
        QWidget.__init__(self, parent)
        self._shape = np.array(["capsule", "circle", "rectangle"])
        self._color = np.array(
            ["blue", "green", "orange", "purple", "red", "yellow"]
        )
        self._layout = QGridLayout(self)
        self._create_leds()
        self._arrange_leds()

    def keyPressEvent(self, e):
        if e.key() == Qt.Key_Escape:
            self.close()

    def _create_leds(self):
        for s in self._shape:
            for c in self._color:
                exec(
                    'self._{}_{} = Led(self, on_color=Led.{}, \
                      shape=Led.{}, build="debug")'.format(
                        s, c, c, s
                    )
                )
                exec("self._{}_{}.setFocusPolicy(Qt.NoFocus)".format(s, c))

    def _arrange_leds(self):
        for r in range(3):
            for c in range(6):
                exec(
                    "self._layout.addWidget(self._{}_{}, {}, {}, 1, 1, \
                      Qt.AlignCenter)".format(
                        self._shape[r], self._color[c], r, c
                    )
                )
                c += 1
            r += 1


app = QApplication(sys.argv)  # type: ignore
demo = Demo()
demo.show()
sys.exit(app.exec_())

Tips

• If you want to be able to toggle the LED, then either use setEnable(True) or pass an empty string to the build argument in Led.
• The status_changed signal will emit a boolean when the LED's state has changed.
• Currently, the only way to shrink the LED beyond the default size is to use setFixedSize
