QImage::fill can't digest what I feed it

[darenw]

I am stumped by this compile error, sure that it's some very simple "obvious" doof-up. I'm hoping to create an image filled with a color.

QImage qim( QSize(24,24), QImage::Format_ARGB32 );
qim.fill( QColor("#FFD07F") );

The compiler from Visual Studio 10 (using command line tools) gripes with:

main.cpp(51) : error C2664: 'QImage::fill' : cannot convert parameter 1 from 'QColor' to 'uint'

Line 51 being the qim.fill() call. The Qt doc for QImage says QImage::fille(const QColor &) exists, and QColor should be fine with a string containing web-style color like that. It sure looks like everything is fine in the source code.

What the heck is the problem?

Curious. GCC compiles this without issue on Linux and Windows, as you would expect.

#include <QtGui>
 
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    QImage qim( QSize(24,24), QImage::Format_ARGB32 );
    qim.fill( QColor("#FFD07F") );
    return 0;
}

#include <QtGui>

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    QImage qim( QSize(24,24), QImage::Format_ARGB32 );
    qim.fill( QColor("#FFD07F") );
    return 0;
}

Does your compiler choke on the example above?

Hi, which Qt version do you use?
QImage::fill(const QColor & color) has been introduced with Qt 4.8, so if you use an earlier version, you compiler is correct
