[Qt-interest] Setting the Window Icon

[O'carroll, David T]

Hi,

Thanks for the reply.
I tried checking if the file existed using the QFileInfo class and it always found the file.
I also used QDir to list the contents of the directory in which all the images I need are stored and it was able to find them all.
This is the code I'm using to check for the file:

QFileInfo file("/path/to/file.png");
if(file.exists())
{
                qDebug() << "Setting window icon";
                QApplication::setWindowIcon(QIcon("/path/to/file.png"));
}
else
{
                qDebug() << "File: " << file.absoluteFilePath() << " not found";
}

This will always output "Setting window icon" and yet the icon is not always set (in fact it is quite rare that it does get set).
Seeing as the file can be read by both QFileInfo and QDir could there be a problem with QIcon?

My guesses this is failure to find image file.
Try to use absolute path instead of relative and check if file exists.
Put some code which will notify you about path when  does not.

Hi,
I am trying to integrate a demo into the Meego IVI UX. I am trying to set the window icon of an application to a different image depending on what QWidget is running. The QWidget is launched as the application starts and is passed to the application as an argument (so it only needs to be set once). Currently I am setting it in main.cpp with:

QApplication::setWindowIcon(QIcon("/path/to/image.png"));

However, this leads to somewhat random results wherein the image is set sometimes and not others. Is there something I'm missing about QIcon (I'm used to working with QPixmap) or am I simply going about this the wrong?

Regards,
Dave
