How to make QListWidget items editable?

[montylee]

I am using Qt 4.3.4. I have created a list widget having some items. I want the items to be editable so that user can modify the contents of the list widget dynamically by double clicking on the list widget item.

Here's what i am doing:

connect (sampleList, SIGNAL (itemDoubleClicked (QListWidgetItem *)), this, SLOT (test (QListWidgetItem *)));
 
void test (QListWidget *item)
{
      sampleList->editItem (item);
}

connect (sampleList, SIGNAL (itemDoubleClicked (QListWidgetItem *)), this, SLOT (test (QListWidgetItem *)));

void test (QListWidget *item)
{
      sampleList->editItem (item);
}

To copy to clipboard, switch view to plain text mode 

While creating the list widget items, i am setting the item flags as:

item->setFlags (item->flags () & Qt::ItemIsEditable);

item->setFlags (item->flags () & Qt::ItemIsEditable);

To copy to clipboard, switch view to plain text mode 

Now, when i run my application, and double click on the list widget item to edit, i get the following error on the terminal:

"edit: editing failed"

Now, my query is that how can i make the list widget items editable? I tried modifying the test () function given above as:

void test (QListWidget *item)
{
      sampleList->openPersistentEditor (item);
}

void test (QListWidget *item)
{
      sampleList->openPersistentEditor (item);
}

To copy to clipboard, switch view to plain text mode 

Using this code, i am able to edit the item but i am not sure if this is the correct way of doing it. Also, i am not sure about the usage of openPersistentEditor ().
