QMap inheritance with QMapIterator
- by gregseth
Hi,
I made a personnal class which inherits QMap:
class CfgMgr : public QMap<QString, CfgSet*> {...}
I'm trying to iterate over all its elements like that:
CfgMgr* m_pDefaults = new CfgMgr;
// .../...
QMapIterator<QString, CfgSet*> ics(*m_pDefaults);
while (ics.hasNext()) {
// doing my stuff
}
And I get the compile error:
Can't convert parameter 1 from 'CfgMgr'
to 'const QMap< Key,T &'
with
[
Key=QString,
T=CfgSet *
]
I tried with a dynamic_cast:
QMapIterator<QString, CfgSet*> ics(
*dynamic_cast< QMap<QString,CfgSet*>* >(m_pDefaults)
);
it compiles, but always returns NULL.
What's wrong? How can I solve this?
