Qwidgetstack, how to ? it doesnt show any widgets Options

[nilch]

I am using the QWidgetStack to create a sideBar element in my program which can change on context - a context sensitive changing sideBar menu element.

So I am adding widgets into the WidgetStack and them calling the widgetStack control in the main screen. On the desktop - this method works fine and I can raiseWidgets as needed to the front.

But on the Zaurus, the whole widgetStack control doesnt show up at all.
There are no errors when using QWidgetStack on Qt/E, but nothing shows at all.

What is heppening here ?Is the QWidgetStack implementation the same in QT/E as in QT.

Code sample as below
-----------------------------
class controlWidgets(QWidgetStack) :
def __init__(self,parent = None,name = None):
QWidgetStack.__init__(self,parent,name)

if name == None:
self.setName('')

self.setSizePolicy(QSizePolicy(4,7,self.sizePolicy().hasHeightForWidth()))
self.setMinimumSize(QSize(90,120))
self.setMaximumSize(QSize(160,420))

self.widgetMain = controls(self) # control is the main widget class
self.widgetLocal = controlLocal(self) #controlLocal is a local widget
self.addWidget(self.widgetMain,1)
self.addWidget(self.widgetLocal,2)

in the main section I call controlWidgets as below
--------------------------------
self.sideBar = controlWidgets(self)
self.sideBar.setSizePolicy(QSizePolicy(0,0,self.sideBar.sizePolicy().hasHeightFo
Width()))
self.layoutSideBar.addWidget(self.sideBar)
self.sideBar.show()



I have read on other threads that the QWidgetStack on QT/E has a bug - is this the reason for the non-visibility of the WidgetStack control on the Zaurus ?
