load image from buffer

[pit_29]

Hi I have managed to load my image from directory now want to build it from buffer but I get errors,
I leave my code here

QBuffer * buffer = new QBuffer (conn);
QImage image = new QImage ();
image-> loadFromData (buffer-> buffer ());

errors are the following:
C: \ ejemplos_qt \ teratermobile-build-simulator \ .. \ teratermobile \ imagen.cpp: 81: error: conversion from 'QImage *' to non-scalar type 'QImage' Request
C: \ ejemplos_qt \ teratermobile-build-simulator \ .. \ teratermobile \ imagen.cpp: 82: error: base operand of '->' has non-pointer type 'QImage'

thanks

Correction code:

QBuffer * buffer = new QBuffer (conn);
QImage* image = new QImage ();
image-> loadFromData (buffer-> buffer ());

Be careful with the types! You create a pointer by calling new and you assign it to a local variable that holds an instance of the class, not a pointer of the instance.

I use this code with my code but I get an error on the part that I have. which is this:

C:\ejemplos_qt\teratermobile-build-simulator\..\teratermobile\imagen.cpp:100: error: no matching function for call to 'QPixmap::fromImage(QImage*&)'

which is in this line
label-> setPixmap (QPixmap:: FromImage (image));

but using this code, the same line does not give me no problems gives me problems:
//QString fileName = QFileDialog::getOpenFileName(this,
//tr("abrir archivo"), QDir::currentPath(),
// "archivos(*.jpg *.png)");
//QImage image(fileName);

label-> setPixmap (QPixmap:: FromImage (*image));

Once again.......be careful with the types. What type you have, what a function needs as argument, what to assign where....this is basic C++ theory.

I've tried that but still functional, I think that image is not an image because when I run it nothing appears on my screen
Could you use this?
QImage image(loadFromData (buffer-> buffer ()))
thanks
