Hi,

I am into the development of an app, which receives data from network, and draws circular regions 192.168.1.250 , which is defined by the data received.
I need to retain the data on the widget for some time 'x' and then change color and after some delay 'y', erase it.

I have already coded it, by retaining the old data in a buffer and redraw all the data , when a new one arrives..

It is consuming lot of time and its not responsive when the data rate is too high..the user has to do other operations also.

I am planning to Shift to Graphics View, (now done using QPainter)

Can some one help me out with code snipptes?
