Draw grid in QGraphicsScene/QGraphicsView
I'm using Qt 5.2 with Qt creator. I' want to draw a lot of rectangle(100 to 1 million) and fill them with 2 colors. To do this quickly I choose to
1- fill background with one color
2-draw the complete grid with big lines
3-and fill each rectangle with the second color.
I've done this with direct2D and GDI, it worked well. But with Qt, I'm lost with QGraphiquesScene/view because all my rectangle need to be a square, but while extending my view I' get a weird result. With direct2D my grid size is the lowest size of my view.
So I need your help. I'm using
What I got with QT

@::drawBackground(QPainter *painter, const QRectF &rect)@
I use rect to get the bound but it seem not work while expanding my view all going weird instead of grow up the size...
I need a grid witch grow up with the view size .
No one knows how to draw a simple grid which grow up with view ?
