Hi,

not 100% sure what you are after, but perhaps a standard tabWidget, with 
a customised Scrollarea forming the panel is one way?

from PyQt4 import QtGui

class TabPane(QtGui.QScrollArea):
    def __init__(self, parent=None):
        super(TabPane, self).__init__(parent)
        frame = QtGui.QFrame(self)
        frame.setFixedSize(300,200)
        self.setWidget(frame)
        self.layout = QtGui.QVBoxLayout(frame) 
        
    def addDock(self, title):
        dw = QtGui.QDockWidget(title, self)
        self.layout.addWidget(dw)
        
if __name__ == "__main__":
    app = QtGui.QApplication([])

    tab_widget = QtGui.QTabWidget()
    for heading in ["Properties", "Schedule", "Pricelist"]:
        pane = TabPane()
        pane.addDock("Hello World")
        pane.addDock("Hello Galaxy")        
        pane.addDock("Hello Universe")        
        
        tab_widget.addTab(pane , heading)
    
    tab_widget.show()
    app.exec_()
