• Win7 Aero blur
• MacOS blur

Install

To install use pip:

pip install PyQt5-Frameless-Window

Or clone the repo:

git clone https://github.com/zhiyiYo/PyQt-Frameless-Window.git
python setup.py install

Requirements

Usage

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

import sys

from PyQt5.QtWidgets import QApplication
from qframelesswindow 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, you can refer to the demo.py.

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. If you encounter this problem on Windows:

   ImportError: DLL load failed while importing win32api

   see my answer on stackoverflow or my blog for the solution.

4. If you are using PySide2 or PyQt6, you can download the code in PySide2 or PyQt6 branch, but they only support Win32 and macOS at present.
