problem with ported canvas example

[bajarangi]

Hi all,

I was trying to use a loaded image on a QT4 GraphicScene in my own code,
and had some problems, so I started working with the Ported Canvas
example to understand a minimum function.

I found what looks like a problem with that example.
In the ImageItem constructor, if I leave the QT3 API as
it is:
pixmap.convertFromImage(image);

The butterfly image displays successfully.

If I try to convert that call to the QT4 api like this:
pixmap.fromImage(image);

The butterfly images do not display.
The rest of the code is the same, and there are no
compile time or run time warnings or errors.

I'm really stumped.
Please help!

QPixmap::fromImage() is a static call returning a pixmap, You have to assign the result to a pixmap variable.

Thanks Wysotta!

Of course it now works fine.

I pledge to read the API documentation more carefully in the future.
