QPainter painter(ui.the_widget_that_is_inside);

You cannot paint like that !!
You will need to subclass ui.the_widget_that_is_inside and do the painting in paintEvent() function.

what do you mean when you say to subclass?

i have edit inside the main widget a simple class(without .ui) and it doesn't work!

i think that i didn't understand you!
