Or clone the repo:

git clone https://github.com/XiaoshuDeXiaowo/QtFramelessWindow
cd QtFramelessWindow
pip install .

Requirements

Usage

To use the frameless window, you only need to inherit FramelessWindow. Here is a minimal example:

import sys

from PySide2.QtWidgets import QApplication
from QtFramelessWindow import FramelessWindow


class Window(FramelessWindow):

    def __init__(self, parent=None):
       super().__init__(parent=parent)
       self.setWindowTitle("PyQt-Frameless-Window")
       self.titleBar.raise_()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    demo = Window()
    demo.show()
    sys.exit(app.exec_())

For more complex requirements, see examples.

Examples

• Normal frameless window
• Acrylic frameless window

Notes

1. FramelessWindow provides a default custom title bar. If you don't like it, just rewrite it as demo.py does.

2. Moving the acrylic window on Win10 may get stuck. At present, there is no good solution. Maybe you can disable the acrylic effect when moving the window, but I haven't done this in the source code.

3. Snap layout is not enabled by default. See zhiyiYo/PyQt-Frameless-Window#56 to learn how to enable it.

4. If you encounter this problem on Windows:

   ImportError: DLL load failed while importing win32api

   see zhiyiYo's answer on stackoverflow or blog for the solution.
