[RQt-devel] unable to draw lines/segments with width>1

[Yihui Xie]

Hi,

I'm not sure if this is a problem related to R 2.13.0 or my hardware,
but I just cannot draw thicker lines or segments now. They do not
appear on the screen but they are actually there, because brushing
still works. It worked when I was using R 2.12. Other graphical
elements are still OK with 2.13.

s = qscene()
root = qlayer(s)
n = 10
x = rnorm(n, 50, 15)
y = runif(n, 20, 80)
test_layer = qlayer(root, function(layer, painter) {
    qdrawCircle(painter, x, y, r = 20, fill = "black")
    qlineWidth(painter) = 3  # only 1 works
    qdrawSegment(painter, 10, 10, 90, 90)
}, limits = qrect(0, 0, 100, 100))
qplotView(s)
