Unable to change the background color of DockLabel

[bea1999]

Hello, i tried to change the background color of DockLabel (class from anaconda package) using
self.ImageDock.label.setStyleSheet("background-color: #04B2E2; color: white;")
the default color is purple : #66c and i wanna change it to blue #04B2E2
BUT IT DIDNT WORK!
changing it from the actual package works but i dont wanna modify the class directly.
Any idea how can i do that dynamically?? thanks!

Hi and welcome to devnet,

Where does that class come from ?
Which Python bindings are you using ?
Can you provide a minimal runnable script that shows this issue ?

sorry i messed up the code in the first reply, i'm new here haha

from PyQt5.QtWidgets import QApplication, QMainWindow
from pyqtgraph.dockarea import Dock, DockArea
import pyqtgraph as pg
import sys

class DockApp(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Dockable Display App")
        self.setGeometry(100, 100, 800, 600)
        
        self.area = DockArea()
        self.setCentralWidget(self.area)
        
        self.set_dock_default()

    def set_dock_default(self):
        """Sets up the dock with a display window."""
        self.image_dock = Dock(name="Display Dock", size=(1, 1))
        self.image_dock.label.setStyleSheet("background-color: #04B2E2;") #change to blu but doesn't work
        self.display_window = pg.PlotWidget(title="Image Display")
        self.display_window.getViewBox().invertY(True)  # Inverting Y axis
        
        self.image_dock.addWidget(self.display_window)
        self.area.addDock(self.image_dock, "top")

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = DockApp()
    window.show()
    sys.exit(app.exec_())
