C++ (Cpp) GFileQueryInfoFlags Examples

Example #1

File: utils.cpp Project: Riateche/ridual

QString get_mime_type(const QString &filename) {
  GFile *file = g_file_new_for_path (filename.toLocal8Bit());
  GError* gerror = 0;
  GFileInfo* gfileinfo = g_file_query_info(file, G_FILE_ATTRIBUTE_STANDARD_CONTENT_TYPE, GFileQueryInfoFlags(), 0, &gerror);
  if (gerror) {
    qDebug("gio error: %s", gerror->message);
    g_error_free(gerror);
    gerror = 0;
  }
  if (gfileinfo) {
    const char* content_type = g_file_info_get_content_type(gfileinfo);
    QString result = QString::fromLocal8Bit(content_type);
    g_object_unref(gfileinfo);
    return result;
  }
  return "application/octet-stream";
