Plotting graph from outside paint event function+ error:Paint device returned engine 0
-
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 QWidget::paintEngine: Should no longer be called QPainter::begin: Paint device returned engine == 0, type: 1 .
Even i set the attribue for WA_PaintOutsidePaintEvent true for qframe of ui.Do i need to include any library to solve it..?
