How to pass object reference to slot?

[Vladislav Lisovenko]

I need to pass object reference to slot function, something like this:
connect(button,SIGNAL(clicked(true)),SLOT(onButtonClicked(MyObject));

I know that it's wrong way, but I don't know how to manage it. I also know about QSignalMapper, but it works only with primitive types and doesn't work with references.

Could You give some hints what's You want to do? Maybe is a better way to do that :)

@Kaluss I have a table view and QlineEdit with button in each cell, and I want to pass QModelIndex when button clicked for futher processing.

Hmm, maybe You can use entered(const QModelIndex & index) signal which is emitted always when You enter particular item. You set internal member to this index and in slot onButtonClicked(bool) u use this member.
What do You think?

@Kaluss Sorry, but I don't understand about internal member and how to link it with index? I also have another variant to solve this problem - just derive QPushButton and make constructor with QModelIndex argument, but I think it's wrong way, it should be simpler.

WidgetWithTableView
{
public:
    WidgetWithTableView();
public slots:
    void onIndexEntered(const QModelIndex & index);
    void onButtonClicked(bool);
private:
    QModelIndex currentIndex;
};
///////////////////////////////////////////////////////
WidgetWithTableView::WidgetWithTableView()
{
     //stuff
    connect(button,SIGNAL(clicked(bool)),SLOT(onButtonClicked(bool));
    connect(button,SIGNAL(entered(const QModelIndex & index)),SLOT(onIndexEntered(const QModelIndex & index));
}

WidgetWithTableView::onIndexEntered(const QModelIndex & index)
{
    this->currentIndex = index;
}

WidgetWithTableView::onButtonClicked(bool)
{
    //stuff
    //if we need index we use  this->currentIndex
}

Is it clear right now?

@Kaluss Thanks Kaluss, it's exactly what I need, thank you very much.
