problem in getting folder icon from folder-path via QMime

[saber]

i found a code that gets icon of a file or folder by it's path .
here is the function .

QIcon geticon(const QString &filename){

    QIcon icon;
    QMimeDatabase mime_database;

    QList<QMimeType> mime_types = mime_database.mimeTypesForFileName(filename);

    for (int i=0; i < mime_types.count() && icon.isNull(); i++){
        qDebug()<< mime_types[i].iconName();
        icon = QIcon::fromTheme(mime_types[i].iconName());
    }

    if (icon.isNull())
      return QApplication::style()->standardIcon(QStyle::SP_FileIcon);
    else
      return icon;
}

there is some problems in this function and i want to fix that

1. it dose not detect if the given path is a folder path ,so it dose not return a folder icon.
2. as i will give it a single file path , i don't want the "QList<QMimeType> mime_types " and the "for loop" in my code.

i tried different way to fix those but failed.
please help me.

@saber If you don't want mime_types and the loop then use http://doc.qt.io/qt-5/qmimedatabase.html#mimeTypeForFile-1

@jsulm
yes i want that mime_types to get it's icon and return the icon .

but problem is i don't know how to do that.
i could not declare the "mime_types" to pass the filepath.

Hi,

@saber said in problem in getting folder icon from folder-path via QMime:

mime_database.mimeTypesForFileName

From the looks of it, you should rather use QMimeDatabase::mimeTypeForFile.

@saber Please read again what I wrote.
Using http://doc.qt.io/qt-5/qmimedatabase.html#mimeTypeForFile-1 you don't need mime_types ...

here is my solution

give it the file path it will return the icon.

QIcon geticon(const QString &filePath) {

    QIcon icon;
    QMimeDatabase mime;
    QMimeType mType;

    mType = mime.mimeTypeForFile(filePath);
    icon = QIcon::fromTheme(mType.iconName());

    if (icon.isNull())
      return QApplication::style()->standardIcon(QStyle::SP_FileIcon);
    else
      return icon;
}
