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.

    subclass QFileSystemModel and reimplement data() method. The following should do what you want:
    @
    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);
    }
    @

    alternatively you can also subclass QFileIconProvider as you already mentioned and reimplement all virtual methods. And set the file icon provider class with QFileSystemModel::setIconProvider(yourIconProvider).

    What exactly do you mean?

    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.

    i haven't looked into the sources of QFileSystemModel yet, but i would bet that it queries the icon from the QFileIconProvider in it's data() method implementation for the decoration role. (In the way like i stated it in the code before)
