Hi,
I am plotting a graph by painting outside paintevent which runs correctly in my linux desktop.And same application when i ran in IMX environment(for which qt is ported),i am getting error message as
painter engine not active.
Do i need to include any library to solve it..?

Please excuse my english...

If you are painting outside the paintEvent it will not work on embedded devices, unless you use X11.

You have to paint everything in the paint event or paint every where to a QPixmap and in the paint event paint the QPixmap.

As far as I know, even under X11, you still need to do the painting inside the paintEvent or it doesn't work.
