QAbstractItemModel Subclass duplicate entries

[pvdk]

Hello people,

I've successfully subclassed QAbstractItemModel to fit my needs. It acts as a frontend for the ls command. Ls feeds output in the following form to my model:

./parentfolder:
subfolder1/
subfolder2/

./parentfolder/subfolder1:
dir/
dir2/
textfile.txt

./parentfolder/subfolder1/dir:

./parentfolder/subfolder1/dir2:

./parentfolder/subfolder2:
textfile1.txt
textfile2.txt
textfile3.txt

And displays it like in the attached image.
The only thing I can't get fixed is the multiple occurence of parents. I've been struggeling with it the whole day so I hope someone with a fresh mind can see what's wrong with my code:

void TreeModel::setupModelData(const QStringList &lines, TreeItem *parent)
{
    QList<TreeItem*> parents;
    QList<int> indentations;
    parents << parent;
    indentations << 0;
 
	for( int r=0; r<lines.count(); r++ ) {
	QString lineData = lines[r].trimmed();
 
		if (!lineData.isEmpty()) {
			qDebug() << QString(lineData) << "\n";
 
			// Line is a dir
			if (lineData.endsWith(":")) {
				// Get rid of the colon
				lineData.chop(1);
 
				// Check if the string is a dot from the beginning of the ls output
				if (lineData == ".") {
					// Get rid of the string
					lineData.clear();
				}
 
				// Check if the line starts with a dot and get rid of it before we replace the backslashes
				if (lineData.startsWith("./")) {
					lineData.replace(QString("./"), QString("/"));
				}
					qDebug() << lineData;
 
					QStringList list = lineData.split("/", QString::SkipEmptyParts);
					qDebug() << list << "start appending parent/child shit \n ";
 
					// Reset the parent FIXME: horrible method
					parents << parents.first();
					for(int p = 0; p < list.size(); p++) {
 
						QList<QVariant> column;
						column << list[p];
 
						parents.last()->appendChild(new TreeItem(column, parents.last()));
						parents << parents.last()->child(parents.last()->childCount()-1);
					}
 
			} else if (lineData.endsWith("/")) {
				qDebug() << "is a directory conjo!!!" << lineData << "\n";
			} else {	
				QList<QVariant> column;
				column << lineData;
 
				parents.last()->appendChild(new TreeItem(column, parents.last()));
				qDebug() << "appended file: " << lineData << "\n";
			}
		}	
	}
}

void TreeModel::setupModelData(const QStringList &lines, TreeItem *parent)
{
    QList<TreeItem*> parents;
    QList<int> indentations;
    parents << parent;
    indentations << 0;

	for( int r=0; r<lines.count(); r++ ) {
	QString lineData = lines[r].trimmed();
		
		if (!lineData.isEmpty()) {
			qDebug() << QString(lineData) << "\n";
			
			// Line is a dir
			if (lineData.endsWith(":")) {
				// Get rid of the colon
				lineData.chop(1);
								
				// Check if the string is a dot from the beginning of the ls output
				if (lineData == ".") {
					// Get rid of the string
					lineData.clear();
				}
				
				// Check if the line starts with a dot and get rid of it before we replace the backslashes
				if (lineData.startsWith("./")) {
					lineData.replace(QString("./"), QString("/"));
				}
					qDebug() << lineData;
			
					QStringList list = lineData.split("/", QString::SkipEmptyParts);
					qDebug() << list << "start appending parent/child shit \n ";
					
					// Reset the parent FIXME: horrible method
					parents << parents.first();
					for(int p = 0; p < list.size(); p++) {

						QList<QVariant> column;
						column << list[p];
						
						parents.last()->appendChild(new TreeItem(column, parents.last()));
						parents << parents.last()->child(parents.last()->childCount()-1);
					}
			
			} else if (lineData.endsWith("/")) {
				qDebug() << "is a directory conjo!!!" << lineData << "\n";
			} else {	
				QList<QVariant> column;
				column << lineData;
				
				parents.last()->appendChild(new TreeItem(column, parents.last()));
				qDebug() << "appended file: " << lineData << "\n";
			}
		}	
	}
}

So, in short: I need my QAbstractItemModel to treat items with the same name under the same parent as one item, and not as duplicates.

Thanks in advance,
