Usage

qmocMethods(x)
qsignals(x)

Arguments

x	A QObject object or derived class (as an RQtClass).

qsignals returns a similar data.frame containing only signal methods and the columns name and signature.

qslots returns a similar data.frame containing only slot methods and the columns name, signature and return.
