[RQt-devel] regressions

[Deepayan Sarkar]

This used to work before:

> qfile <- Qt$QFile("/tmp/foo.R")
> stream <- Qt$QTextStream(qfile)
Error in qinvokeStatic(cl, name, ...) :
  Unable to disambiguate method QTextStream::QTextStream

but no longer. A workaround is

> stream <- Qt$QTextStream()
> stream$setDevice(qfile)

Similarly,

> Qt$QPen(Qt$QColor())
Error in qinvokeStatic(cl, name, ...) :
  Unable to disambiguate method QPen::QPen

Any idea what might be going on?


Even worse, segfaults with

> stream$string()

 *** caught segfault ***
address 0x8, cause 'memory not mapped'

Traceback:
 1: .Call(qt_qinvoke, x, method, FALSE, list(...))
 2: qinvoke(<environment>, "string", ...)
 3: stream$string()


and with

> foo <- "foobar"
> stream <- Qt$QTextStream(foo)

 *** caught segfault ***
address 0x8, cause 'memory not mapped'

Traceback:
 1: .Call(qt_qinvokeStatic, x, method, list(...))
 2: qinvokeStatic(cl, name, ...)
 3: Qt$QTextStream(foo)

(But I guess this usage doesn't make sense for us.)
