PyQt - QLabel: set color of text and background

PyQt - QLabel: set color of text and background

To set the color of text and background for a QLabel in PyQt, you can use the setStyleSheet method and provide a style sheet. Here's an example:

from PyQt5.QtWidgets import QApplication, QLabel, QVBoxLayout, QWidget from PyQt5.QtGui import QPalette, QColor class MyWindow(QWidget): def __init__(self): super().__init__() self.init_ui() def init_ui(self): layout = QVBoxLayout() # Create a QLabel label = QLabel('Hello, PyQt!', self) # Set the text color label.setStyleSheet('color: blue') # Set the background color palette = label.palette() palette.setColor(QPalette.Window, QColor('lightgray')) label.setPalette(palette) layout.addWidget(label) self.setLayout(layout) self.setWindowTitle('QLabel Text and Background Color') self.setGeometry(300, 300, 300, 200) if __name__ == '__main__': app = QApplication([]) window = MyWindow() window.show() app.exec_()

In this example:

  • The QLabel is created with the text 'Hello, PyQt!'.
  • The setStyleSheet method is used to set the text color to blue ('color: blue').
  • The palette is obtained from the label, and the background color is set using palette.setColor(QPalette.Window, QColor('lightgray')).
