Enumerate/print all QRC resource from QML

Sebastian Mosiej

Hi,
I would like to print (for debug purpose) all available QRC elements from QML.
For C++ there's widely available

 QDirIterator it(":", QDirIterator::Subdirectories);
 while (it.hasNext()) {
     qDebug() << it.next();
 }

I found this code snippet to use from QML

        FolderListModel {
            id: folderModel
            folder: "qrc:/"
            nameFilters: ["*"]
            onCountChanged: {
                console.log("=> QRC Model content changed to %1 elements".arg(
                                folderModel.count))
                for (var i = 0; i < folderModel.count; i++) {
                    console.log("=> %1".arg(folderModel.get(i, "filePath")))
                }
            }
        }

Unfortunately, above solutions prints only TOP level folders in QRC (according to folder value). It doesn't recursively print content.
And I would like to see this.
How to do it?
PS: I can use GammaRay which will show this and it's acceptable solution (as a external GUI tool). Yet, still code solution is most welcome.

Make a model (or just a QStringList) in c++ and expose it to QML.

FolderListModel.isFolder() can be used to build a list of all subfolders to traverse.
eg:

FolderListModel {
  id: folderModel
  folder: "file:///path/to/root"
  property var folders: []
  property var files: []
  onFolderChanged: {
    for (var i = 0; i < folderModel.count; i++) {
        var filePath = "file://" + folderModel.get(i, "filePath");
        if (folderModel.isFolder(i))
            folders.push(filePath);
        else
            files.push(filePath);
    }
    if (folders.length)
        folderModel.folder = folders.pop();
    else
        console.log("All files:", folderModel.files);
  }
}

This works for a file: url. I suspect it will with a qrc, but have not verified.

Thank you all for your feedback.
I just want to test if all QRC elements were loaded properly and their paths are built correctly.
At current project we use 100% QML and there's no place for me to expose C++ (or it would take too much time for debug purpose).
GammaRay is good enough at the moment.
