<![CDATA[Custom icons for QFileSystemModel]]>Hi ,
I was wondering if anybody knew of a way to use custom icons the file system uses to show your files/folders....The Doc has pointed me to QFileIconProvider but i did not find anyway to match "QFileIconProvider::IconType":http://qt-project.org/doc/qt-5.1/qtwidgets/qfileiconprovider.html#IconType-enum to the custom icons of my choosing.

Any help would be appreciated.

(In the way like i stated it in the code before)

I thought I could use QFileInfoProvider to set the icons that QFileSystemModel uses to show the icons for files/folders.If this could be done there should be some kind of setIcon()/setIcons() function to set them right?

May be I am getting wrong the intended usage of QFileInfoProvider.

And set the file icon provider class with QFileSystemModel::setIconProvider(yourIconProvider).

@
QVariant MyFileModel::data ( const QModelIndex & index, int role ) const
{
if( index.column() == 0 && role == Qt::DecorationRole )
//you may want to check "index.data().toString()" for the file-name/-extension
return QVariant::fromValue(icon);
else
return QFileSystemModel::data(index, role);
}
