Hi All
QMultiHash<Qstring,int>hh;
I need to find some key and change their values.
I found If I use QmutableHashIterator<Qstring,int>it , its
bool
findNext ( const T & value )
Its parameter is a value, not a key.
So I need to :
While(it.hasNext())
{
It.next();
If(it.key() == ikey)
{
It.setValue(ivalue);
}
}
I must to check every item? Who have a better method?
2. Qhash:
Some books said Qhash is unorderred?
But I test it.
Qhash<Qstring,int>hh;
I insert some string, and loop the hash by QhashIterator, I found the string is orderred.
And I test it Qhash<int,Qstring>, and print key, and found they still orderred.
Why books said it is unorderred?
Thanks
ken
