Column/Row no of ComboBox Widget in Table

[ankurjain]

hi guys,
i've done filtering in my table.
i've set a combo Widget in a table in first row.each combo in each column all the text of the cells below it. then whatever text i select the following rows will be shown or hidden.

i used :

QTableWidget *table = new QTableWidget;
table->setCellWidget(row,col,comboWidget);
connect(comboWidget, SIGNAL(activated(const QString &)),table,SLOT(change(const QString &)));

QTableWidget *table = new QTableWidget;
table->setCellWidget(row,col,comboWidget);
connect(comboWidget, SIGNAL(activated(const QString &)),table,SLOT(change(const QString &)));

To copy to clipboard, switch view to plain text mode 

Now i want the row no or column no of which the combo is selected.
column no for matching the item selected from the combo to match in the column,
row no to hide/show the row.

how can i implement it ?
