I have a QObject, that emits a signal as float. What is the most pythonic way to convert this to str for a QLabel.setText method?
from PyQt5.QtCore import QObject, pyqtSignal
from PyQt5 import uic
from PyQt5.QtWidgets import QMainWindow, QLabel
class SerialComponent(QObject):
value = pyqtSignal(float)
def loop():
value.emit(1.0)
class Main(QMainWindow):
def __init__(self):
super().__init__()
uic.loadUi("Main.ui", self)
component = SerialComponent()
component.value.connect(label_display.setText)
This will result in
TypeError: setText(self, str): argument 1 has unexpected type 'float'
What is the most pythonic way to convert this pyqtSignal to str?
Solution of the problem
Signal has reasonable signature, I'd recomend to modify slot.
component.value.connect(lambda value: label_display.setText("{.1f}".format(value)))
