Question

I’d like to make a panel-like application using PyQt4 for Linux. for this i need the window i created:

• to be undecorated
• to have reserved space
• to appear on all workspaces

From reading the documentation i’ve got the idea that i should use QtWindowFlags. But i have no clue as to how to do that. Also i believe there should be a Qt.WindowType hint somewhere telling the WM the window’s a “dock” application. I have made this with pygtk following this thread, but here with Qt i don’t really know how to handle this. (I need Qt for its ability to theme/skin application more easily.)

Below is the current code i made (nothing extraordinary).

import sys
from PyQt4 import QtGui

class Panel(QtGui.QWidget):
def __init__(self, parent=None): ## should the QtWindowFlag be here?
    QtGui.QWidget.__init__(self, parent) ## should the QtWindowFlag be there as well?

    self.setWindowTitle('QtPanel')
    self.resize(QtGui.QDesktopWidget().screenGeometry().width(), 25)
    self.move(0,0)

def main():
    app = QtGui.QApplication(sys.argv)
    panel = Panel()
    panel.show()
    sys.exit(app.exec_())
    return 0

if __name__ == '__main__':
    main()

Can anyone help me with this? Thanks 🙂

The solution is to use Python-Xlib, and it has been described in an answer on a universal way to reserve screen space on X.
