Release memory with the QImage
How I can clear or release memory associated witht he QImage? now I am doing like this
image = new QImage;
I know this is not a good way, but I need to get a QImage with null as shown above, so please help
the above way is Ok, although I'm curious why you use isNull() instead of just deleting it.
Also notice that you probably want to avoid using new/delete for QImage. Its an internally ref-counted value type.
@image = QImage();@
should also release memory, and you do not need to make image a pointer to QImage to use it.
Works, as long as you are certain that image is a valid pointer. Are you sure you need to use a pointer though?
Thanks, I changed the pointer option, and use image = QImage() to make it a null, as said by Tobias Hunger
