[solved]Get filepath and filename from qtreewidget

[kamlmish]

Hi
I have a strange issue where I need to get filepath and filename on a single click of the item in the qtreewidget



class browserwindow: public QTreeWidget
{
Q_OBJECT
public:
browserwindow(QWidget* parent = 0);
~browserwindow();
//functions
void populate();

public slots:

QModelIndex getDetails(const QModelIndex& index);

public:
QDirModel* model;
QTreeView* tree;
QModelIndex index;

};




#include "browsemodel.h"

browserwindow::browserwindow(QWidget* parent)
:QTreeWidget(parent)
{
model = new QDirModel(this);
tree = new QTreeView(this);
populate();

}

browserwindow::~browserwindow()
{
delete tree;
delete model;
}

void browserwindow::populate()
{
tree->setModel(model);
tree->setRootIndex(model->index(QDir::homePath()));
tree->setWindowTitle("Browse for folder");
tree->resize(820, 7200);
connect(this,SIGNAL(clicked(QModelIndex)),SLOT(get Details(QModelIndex)),Qt::DirectConnection);

}

QModelIndex browserwindow::getDetails(const QModelIndex &index) // to get details on the index on single click
{
QString filename = model->fileName(index);
return model->index(0);

}

Issue is that I get a SIGSERV segmentation fault when I run the above code
my main objective is that , when a user clicks on the "browse" button(add_link_folder.png), the browser should open(browser.png)
when the user single clicks on any file in the browser, it should go back to the (add_link_folder.png) and the location and name shud display the filepath and filename respectivly

You don't need to delete tree and model. They get deleted by Qt. Further what is the purpose of subclassing QTreeWidget and create a QTreeView inside? Also do you have seen QFileDialog?

And where exactly crashes the program?

[kamlmish]

1) I needed to display the filesystem , and therefore I used a QDirModel and QTreeView to display the filesystem
The filesystem gets displayed in a new window(browser.png)
2) QFileDialog would provide me a dialog box where I can select specific files and directories , but my objective is to display the filesystem in a tree view , select a specific file from the treeview , the selected file name and path would be displayed in a text browser

The crash happens at
connect(this,SIGNAL(clicked(QModelIndex)),SLOT(get Details(QModelIndex)),Qt::DirectConnection);

well within the posted code I don't see an error. Can you post the backtrace since it isn't (most likely) the connection statement.
