how blocked center in QGraphicsScene

[estel]

hello,
for example I have QGraphicsScene size 500x500. I put line on cords: from (10,30) to (70,70) and i have no idea why line is on center of the scene, could you explain me why? Do you know how to off the "center" option?

its the default behavior. Use QGraphicsView::setAlignment() to change that.

So there is no way to put the line exactly on coords from (10,30) to (70,70)? not alignt to center, not align to left but exactly from (10,30) to (70,70)

there is, as I have written! Just align the sceen via QGraphicsView::setAlignment() to the top left of your view and then when you draw the line from (10,30) to (70,70) it is displayed from (10,30) to (70,70).
