Implement a code before closing the Tab/Widget

[Prmego]

I have the following program:

Each tab has hidden data which contain the full path of the file (I have used setProperty function to assign the hidden data to the tab/widget).
Now, when you click on the close button, I want to get the hidden data of this window before implements the closing command.

Note that I have used tabCloseRequested slot but it returns wrong data.

QObject::connect(this->tabs, SIGNAL(tabCloseRequested(int)), this, SLOT(on_subWindow_tabCloseRequested(int)));

void PSubWindow::on_subWindow_tabCloseRequested(int index) {
    qDebug()<< this->tabs->tabText(index); // return empty string.
}

What is the signal which responsible for closes the tab/widget, but it must give me a possibility to implement a code before closing the tab/widget?

@Prmego Should work. Did you check the value of index?

@jsulm: Yes, I did and the index is correct, but the tabText(index) returns an empty string.
