Error in viewGeometry(scene) : object 'scene' not found about qtpaint HOT 5 CLOSED

Please let me know if it doesn't work.

Thanks. qlayer(qscene()) works, but the cranvas example still does not work for me.

Same error or something else?

It seems to be related to commit 0573db6

.

A more realistic example would be:

library(cranvas)
qtennis <- qdata(tennis)
qscatter(first.serve.pct, second.serve.pts, data=qtennis,
xlab="First Serve %", ylab="Second Serve Points")

resulting in

The same error. The problem is that parent is NULL in the call to layer from qscatter. See e.g. the layer.main at cranvas/R/qscatter.R:259+:

  layer.main = qlayer(
    paintFun = main_draw,
    mousePressFun = brush_mouse_press, mouseReleaseFun = brush_mouse_release,
    mouseMoveFun = brush_mouse_move, hoverMoveFun = identify_hover,
    keyPressFun = key_press, keyReleaseFun = key_release,
    wheelFun = mouse_wheel,
    focusInFun = function(layer, event) {
      common_focus_in(layer, event, data, meta)
    }, focusOutFun = function(layer, event) {
      common_focus_out(layer, event, data, meta)
    },
    limits = qrect(meta$limits), clip = TRUE, cache = TRUE)

Thanks. It works now.
