Thanks jlittle and RobertoColombo for you comments.

I am ok with useing the QT Designer or setting layouts through code.
I see now that it depends on how you are setting out you Dialog/Window to get the best way to layout your controls.
The above was just my way of finding out how to get a responce from the widgets i.e slider so I could get something to happen it is/was just a very simple exersise.
I have now moved on from this and started putting together my "real" functions that I will upload as and when I have finished them, keeping in mind we have got to wait for the next update to the Iclone Python API to move forward is many areas.

Many Thanks
Chris.
