[SOLVED] Questions about creating a mini file browser.

[Leon]

What i want to achieve is a mini file browser like this

which shows only folders and .mp3 files
So until now i have achieved someting like these:
!http://i.imgur.com/XY5eKTG.png(2)!

With this code:
@void MainWindow::on_files_path_textChanged(const QString &path)
{
if(path.isEmpty() || !QDir(path).exists())
return;

//we want the path to always end with a "/". Also we want to see if the user
//just deleted a trailing "/", if so do not take actions.
if(path.right(1)!="\\" && path.right(1)!="/")
{
    if(currentPath.left(currentPath.count()-1)==path)
        return;
    currentPath=QDir::toNativeSeparators(path+"/");
}
else
{
    if(currentPath==path)
        return;
    currentPath=path;
}

updateFilesListWidget();

//monitor the path for any possible change at it's subfolders/audio files
if(watchFolders_)
    delete watchFolders_;
watchFolders_ = new QFileSystemWatcher(this);
connect(watchFolders_, SIGNAL(directoryChanged(QString)), this, SLOT(updateFilesListWidget()));

if(currentPath.count()!=3)
    settings.setValue("current_path", currentPath.left(currentPath.count()-1));
else //for hard drives we want to save them as c:/ not as c:
    settings.setValue("current_path", currentPath.left(currentPath.count()));

}

void MainWindow::updateFilesListWidget()
{
QDir dir(ui->files_path->text());

ui->files_listWidget->clear();

QStringList list_of_subfolders = dir.entryList(QDir::Dirs | QDir::NoDotAndDotDot, QDir::Name);
for(int i=0; i<list_of_subfolders.count(); i++)
{
    QListWidgetItem *folder = new QListWidgetItem;
    folder->setText(list_of_subfolders.at(i));
    folder->setIcon(QIcon::fromTheme("folder", QIcon(":/icons/Pictures/folder_icon.png")));
    ui->files_listWidget->addItem(folder);
}

QStringList list_of_audio_files = dir.entryList(QStringList("*.mp3"), QDir::Files ,QDir::Name);
for(int i=0; i<list_of_audio_files.count(); i++)
{
    QListWidgetItem *audio_file = new QListWidgetItem;
    audio_file->setText(list_of_audio_files.at(i));
    audio_file->setIcon(QIcon::fromTheme("audio-x-generic", QIcon(":/icons/Pictures/audio_icon.png")));
    ui->files_listWidget->addItem(audio_file);
}

}

void MainWindow::on_files_listWidget_itemDoubleClicked(QListWidgetItem *item)
{
ui->files_path->setText(currentPath+item->text());
}@

My problem here, is that i am using a folder/audio icon of mine, and not using system's default and generally this seems a bad way to do a file browser...

i tried with
@QFileSystemModel model = new QFileSystemModel;
model->setNameFilters(QStringList(".mp3"));
model->setNameFilterDisables(false);
model->setRootPath(path);
ui->treeView->setModel(model);
ui->treeView->setRootIndex(model->index(path));@

which creates this

but i don't know how to hide the Size/Type/Date Modified and also the triangle to show the subfolders of this folder..

Just quick thought. How about using listView to show the FileSystemModel ?
@
QListView *lView = new QListView;
lView->setModel(model);@
