QtCanvasPolygon does not paint

[YuriyRusinov]

Hello, All !

I want to draw polygon on QtCanvasView. I make

QtCanvasView *view;
QtCanvasPolygon scrPol (view->canvas());
scrPol.setPoints (scrPts);
QPen selPen (Qt::red);
scrPol.setPen (selPen);
 
QBrush selBrush (Qt::red, Qt::DiagCrossPattern);
scrPol.setBrush (selBrush);
view->repaint ();

QtCanvasView *view;
QtCanvasPolygon scrPol (view->canvas());
scrPol.setPoints (scrPts);
QPen selPen (Qt::red);
scrPol.setPen (selPen);

QBrush selBrush (Qt::red, Qt::DiagCrossPattern);
scrPol.setBrush (selBrush);
view->repaint ();

To copy to clipboard, switch view to plain text mode 

But my polygon doesn't paint, I check coordinates of vertexes, all are correct.

Thanks in advance.

Are you sure you are not drawing off screen?

BTW, the code you posted is not exactly valid. Is that what you really use, or is it something you just gave as an example?

something you just gave as an example?

I put this view on frame and another objects draws successfully.

Have you tried setting a width for the pen?
