[PyQt] Work-around for “.cascadeSubWindows” oversize

[Pietro Moras]

Thanks to David's hint (see), I've detected the cause of the “.cascadeSubWindows” oversizing of child sub-windows, and developed a work-around as here follows. 
Problem had probably to do with MDI window size taken by PyQt4 in place of the Central Widget “mdiArea”.
See you, next time.
- P.M.

def cascadeFit(self): #<-"Fit" function definition

#--compute cascade offset dimensions

rgCx=rgL[1].x()
rgCy=rgL[1].y()

rgCx=rgCx*(rgN-1) #compute total cascade offset
rgCy=rgCy*(rgN-1)



#<-loop resize all sub-windows, so to fit them into available room
