Hi,
You can have a look in "here":http://qt-project.org/forums/viewthread/16673/ , There a QTableView is used instead of QTableWidget(your requirement).
Your code work's for other cells in the tableWidget if i write,
@ connect(ui->tableWidget,SIGNAL(cellClicked(int,int)),this,SLOT(remarksCall(int,int)));@
Also try to Right Click on your pushButton. It will show a messageBox with row and columns. You need to handle for Left Click.
You can have a look at "QSignalMapper":http://qt-project.org/doc/qt-4.8/qsignalmapper.html#details.
Also in line 4 it should be
@QTableWidgetItem* theItem = ui->tableWidget->item( row, col); @
instead of ui.tableWidget :)

QPushButton does not have a signal cellClicked(int,int). It has, for example, a clicked() signal, that you can connect to your slot. clicked() doesn't have any arguments, you'll have to do some bookkeeping yourself, for example using a [[Doc:QSignalMapper]].

hi, try this
@
connect(ui->tableWidget, SIGNAL(doubleClicked(QModelIndex)), this, SLOT(getText()));
// or
connect(ui->pushButton, SIGNAL(clicked()), this, SLOT(getText()));
@
and
@
void tableDialog::getText(){
QString text;
text = ui->tableWidget->item(ui->tableWidget->currentRow(), ui->tableWidget->currentColumn())->text();
}
@
