After a bit of trial and error, it seems that signatures with "plain" or
"const" arguments work okay, but the ones with "pointer" arguments
don't. That is, unless the full C++ signature is used, in which case it
always works:
m.triggered['QAction *']
<bound signal triggered of QMenu object at 0x2512b00>
c.activated['const QString &']
<bound signal activated of QComboBox object at 0x18308c0>
(Is it intended that these latter two variants work? It doesn't seem to
be documented anywhere).
Qt treats const QString& and plain QString as equivalent as far as signal
arguments are concerned. However QAction* is different to QAction. A
QObject derived instance will only ever be passed as a pointer, but that's
not true for other types. Therefore, for consistency, I think it would be
wrong to strip the "*". I agree the documentation could be clarified.
Okay, thanks - the current behaviour makes sense now.
