Any news on what the errors actually are?

Line 11. is very, very strange. Why do you pass the QDeclarativeView to ::grabWidget()? Should it not be a real object? And why do you return QPixMap and then not do anything with it (line 11 of QML file)?

Thanks. I have done many errors because i’m new to c++ and qt. I’ve tried Peppy code but it anyhow shows these errors: invalid use of QPixmap::save; expected primary expressions before ‘bool’.

I would suggest you to look firstly at pure C++ basics of OOP, because this is not good way how to teach you, how to use C++ neither Qt/QML…

We could teach you here basics of language C++, but it’s not good idea, because there are tons of tutorials and basics of C++ on the Internet…you should google it first.

I think, tutorials will be better than “try and hope” programming.

The whole function written above is logically wrong… that’s all what I would say to that. And to that error. You can not use QDeclarativeView as stand-alone name for something – that’s the reason why it was expecting something more (name of variable) – that is one of the basics for C++.

Best regards,
Peppy.

—Update: I’ve corrected some errors but doesn’t work yet.

how does it look like after you have rewritten it?

I wrote a class to acquire a screenshot in QML once. It’s designed for QtQuick 1.1, I haven’t updated it for 2.0. Here’s the code:

screensnapper.h

screensnapper.cpp

Use it in QML like so:

See how that does for you. :)

EDIT: Oops, I forgot the code to register it… Assuming your QDeclarativeView is called view, you’ll need to do this before you load the QML:

thank you very much, but i’m getting this little error(I’m getting errors and errors also with little things these days): base operand of ‘->’ has non-pointer type ‘QDeclarativeView’
Here’s code.

OK, that’s not going to work; you’re creating a worthless QDeclarativeView. You need to get the engine from the actual QML viewer and set the image provider before loading the QML, like so:

The error you received was simply pointing out that you were using the dereferencing member selection operator (->) when you didn’t have a pointer to an object, you just had the object. In that case, you would need to use the normal member selection operator, which is a dot.

I’ve already tried it before your post but it was showing this errors(it’s a malediction): -invalid use of incomplete type ‘structQDeclarativeEngine’(line 9) & -forward declaration of ‘structQDeclarativeEngine’

Now it’s angry because the compiler doesn’t actually know what QDeclarativeEngine is — you need to include the header for it:

Error: QML Image: Failed to get image from provider: image://snapper/snapshot.
P.S. : thanks to be so patient.
EDIT: It works perfectly on a symbian phone. It doesn’t work in Qtsimulator.

Any way to save it to the phone memory?
