QCryptographicHash to hex string ?

Message 1 in thread

I have a QCryptographicHash and I want to generate a
QString containing a hex representation of the
QByteArray returned by the result() method.

Can someone suggest how that can be done ? I can't
see a straightforward method at present.

this should do what you want.

Thanks. I finally ended up with:

QString hex_result(digest.result().toHex().constData());

which seems a bit verbose. Can it be done more simply ?

Doesn't the following work for you?
QString hex_result(digest.result().toHex());

This uses the following QString constructor:

Thanks. That works fine. I didn't notice that ctor.
There's too many of them.  ;-)

You could also do:

    QString hex_result = digest.result().toHex();

Which looks cleaner.

Hi All
1.I saw this sample program
http://doc.trolltech.com/3.3/showimg-example.html

I need help how to use this code in eclipse-QT integration. What project do
I open? How do I use it?

You're looking at the wrong examples, you're working on Qt 4.x (since you use the eclipse integration) but you're looking at Qt 3.3 examples (Qt 3 is no longer supported, it's here for legacy reasons)

Look here instead: http://doc.trolltech.com/4.3/widgets-imageviewer.html

Cheers,
Peter

Thanks Peter
Do you have any idea how do I take those file and build them in the Eclipse?
I tried to open the files but I am not sure how to build hem under QT

Also there is exe file in the folder. I can open it, but when I try to open
image file, I get message "cannot load........."(file path)

Thanks
