Hi and welcome to devnet,

Which version of PySide6 are you using ?

On a side note, there is a Chinese sub-forum if you would like to get help in your mother tongue.

Oh!I forget to mention to my pyside6 version. It is 6.7.2. Thank you for informing me that there is a Chinese forum available.

Can you provide a minimal runnable script that shows this behavior ?

import sys

from PySide6.QtCore import Slot
from PySide6.QtWidgets import QApplication, QWidget, QLabel, QPlainTextEdit


class Hello(QWidget):
    def __init__(self):
        super().__init__()
        self.setFixedSize(200, 200)

        self.input0 = QPlainTextEdit(self)
        self.input0.setStyleSheet("color: white;")
        self.input0.setGeometry(20, 20, 100, 50)
        self.input0.textChanged.connect(self.labelChange)

    @Slot()
    def labelChange(self):
        self.input0.setToolTip(self.input0.toPlainText())


if __name__ == '__main__':
    app = QApplication([])
    s = Hello()
    s.show()
    sys.exit(app.exec())

emmm,如此看来，好像是因为"setStyleSheet"中background-color: rgb(101, 115, 130)无法改变tooltip的"background-color"。

emmm, It seems that it is because the background color: rgb (101, 115, 130) in the "setStyleSheet" cannot change the "background color" of the tooltip.

@SGaist
Hey, bro.So how can i solve this problem in the win10?or how can i set tooltip backgroundColor in the win10?

[SGaist]

Sorry, I just tested it on macOS (I don't have a Win10 machine at hand), and it's working properly.

Can you test your application using the fusion style ?
