    Default QTableWidget crashing

    hey there i have set up a QTableWidget called demands and is set up with a signal and slot of the type below

    Qt Code:
    1. connect(demands, SIGNAL(itemChanged(QTableWidgetItem*)), this, SLOT(obtain_values(QTableWidgetItem*)));
    To copy to clipboard, switch view to plain text mode 

    but when i try to add a item to the table from a seperate slot that i have using a button - the program crashes. when i take the line above out it adds the item no problem, but i need that line to get the data from the table....is there any way to get around this so that i can get data from the table and add items outside the constructor?

    Maybe obtain_values() triggers the itemChanged() signal?

    Why it must be connected to the itemChanged() signal?

    What does the obtain_values() method do? Does it read data into the QTableWidgetItem or store data from the QTableWidgetItem somewhere?
