Table Model / View Problem -- Data Not Displaying

Hello everyone,

I'm having a difficult time getting a table set up. I subclassed QAbstractTableModel as such:

Code:

---

int FileModel::rowCount(const QModelIndex &parent) const {
 
	return files.count();
}
int FileModel::columnCount(const QModelIndex &parent) const {
	return 4;
}
QVariant FileModel::data(const QModelIndex &index, int role) const {
	printf("row %d\n",(int)index.row());
	if (!index.isValid())
		return QVariant();
 
	if (index.row() >= files.size())
		return QVariant();
 
	if (role == Qt::DisplayRole) {
		printf("%s\n",files.value(file_list.at(index.row()))->m_path.c_str());
		return QString(files.value(file_list.at(index.row()))->m_path.c_str());
	} else {
		return QVariant();
	}
}

---

I set the model in a view like this:

Code:

---

FileModel fmodel;
	QTableView *table = new QTableView(this); 
	table->setModel(&fmodel); 
	table->setAlternatingRowColors(true); 
	table->show();

---

However, an empty table shows up with the correct number of rows and columns. I'm not sure why this is happening and I've tried just about everything I can think of.

Any ideas?

Thanks!

The model gets automatically destroyed when going out of scope. Allocate it on the heap:

Code:

---

FileModel* fmodel = new FileModel(this);
QTableView *table = new QTableView(this); 
table->setModel(fmodel);

PS. Have you noticed QDirModel? :)
