problem in xml parsing

[Shawn]

code like this:


Paser::Paser(QObject *parent)
: QXmlDefaultHandler()


QXmlInputSource inputSource(&file);
QXmlSimpleReader reader;
Paser *handler;
reader.setContentHandler(handler);
reader.setErrorHandler(handler);
bool xx;
xx = reader.parse(inputSource);

I trace the steps when debugging, seems that the program never enter the "paser.cpp" file, what does that mean?

[jacek]

Where do you initialize "handler"?

[Shawn]

what should I do to initialize it ?

[wysota]

Create an object and assign it to the pointer. Thus far you only have a piece of memory that can point to a "Paser" object, but not the object itself.

thank you very much, wysota!
now it works!

thank you.
