Question

我正在尝试在pyqt5中编写的应用程序始终在所有cinnamon/gnome个虚拟工作空间中可见。
示例： 'conky'
但调查QDesktopApplication，QWindow和QScreen似乎并不正确。请问任何地址？

修改：我已经在Keep a application window always on current desktop on linux and mac看到了答案，这是一个C ++答案，但我的问题是关于pyQt5。似乎方向是使用一种C ++包装器。

Answer 1

在以下代码中，可以在所有工作空间中显示一个简单的文本框。这可以使用python-ewmh包将_NET_WM_DESKTOP提示设置为0xffffffff。

        # panel size and position
        self.setFixedSize(300, 200)                     # width, height
        self.move(100, 100)                             # x, y

        self.setLayout(v_layout)

        # show the panel
        self.show()

        # show the panel in all workspaces

        ewmh = EWMH()
        all_wins = ewmh.getClientList()
        wins = filter(lambda w: w.get_wm_class()[1] == 'example.py', all_wins)
        for w in wins:
            ewmh.setWmDesktop(w, 0xffffffff)
        ewmh.display.flush()


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    p = Panel()
    sys.exit(app.exec_())

PyQt5应用程序在所有肉桂/侏儒工作区中都可见
