The only difference to your example is that I allocated the dialog on the stack. A modal dialog is one of the cases where it is acceptable to allocate a QWidget on the stack. QDialog::exec() blocks as long as the modal dialog is accepted/rejected.

I assumed that "formCari" is a subclass of QDialog. You have used exec():

void slotCariEdit(QTreeWidgetItem *item)
{
	...
	formCari *ca = new formCari(this, itemcari->statusTip(0));
	ca->exec();
	...
}

void slotCariEdit(QTreeWidgetItem *item)
{
	...
	formCari *ca = new formCari(this, itemcari->statusTip(0));
	ca->exec();
	...
}

So isn't "formCari" a subclass of QDialog? Or did you just mix operators "." and "->" up or even forget an include statement?

We have solved the problem thank you very much,

We have tried to change some codes

connect(tableCariler, SIGNAL(doubleClicked(QModelIndex)), parent, SLOT(slotCarilerEdit(const QModelIndex)));

void slotCarilerEdit(const QModelIndex qm)
{

formCari *ce = new formCari(this, qm.sibling(qm.row(),0).data().toString());
ce->exec();
return;

}

Now we would like to do something else with this table. We would like to select something from the the table and send it to slotCarilerEdit with a push button. Any suggestion that we could use?

In Qt, how do you act in general to a button click? The answer is; signals and slots.

[aekilic]

Yes, we know about the signals and slots but, is it possible to select from table?

To tell more,

for the doubleClick

connect(tableCariler, SIGNAL(doubleClicked(QModelIndex)), parent, SLOT(slotCarilerEdit(const QModelIndex)));

the signal starts from tableCariler

we dont know how to connect tablecariler with a push button so that it will take the QModelIndex from tableCariler?

Maybe you could rely on the fact that the modal formCari dialog was shown when the user double clicked on some certain item. So as long as the dialog is blocking the users input, the same item remains active in the table view.

So maybe you could just connect to the clicked() signal and act in the view according to the current index.

[aekilic]

But if we say we have a slot like this

connect(pushInceleCari, SIGNAL(clicked(QModelIndex)), parent, SLOT(slotCarilerEdit(const QModelIndex)));

how could program could understand that there should be link between table and button?

[jpn]

connect(pushInceleCari, SIGNAL(clicked(QModelIndex)), parent, SLOT(slotCarilerEdit(const QModelIndex)));

You cannot do this. You cannot add random parameter types to signals. QPushButton offers a signal clicked(), not clicked(QModelIndex).

connect(pushInceleCari, SIGNAL(clicked()), parent, SLOT(doSomething()));
 
void doSomething()
{
    QModelIndex idx = tableView->currentIndex();
    ...
}

connect(pushInceleCari, SIGNAL(clicked()), parent, SLOT(doSomething()));

void doSomething()
{
    QModelIndex idx = tableView->currentIndex();
    ...
}
