Qtableview calculation in column
-
i have two tables(qtableview)
so how can i store the column data so i can use everywhere as now done like thisfor (int i = 0, maxI = table1->rowCount();i <= maxI;++i) { bool ok1, ok2; double n = table1->data(table1->index(i, 5)).toDouble(&ok1); double pitch = table1->data(table1->index(i, 4)).toDouble(&ok2); if (ok1 && ok2 && pitch && n != 0) table1->setData(table1->index(i, 8), (n+2)/pitch); } how can i store this setdata in some variable so can use in other column calculations ?also in table2 col 1and 2 combobox based on user input in table1 col1
so now when user select in table2 as col1 as input 1 col2 input 2 if user select input 2 input 3 so that pitchdiameter ratio of these should result in table2 col3 how to do this? -

also you can in table2 col 1and 2 combobox based on user input in table1 col1
so now when user select in table2 as col1 as input 1 col2 input 2 if user select input 2 input 3 so that pitchdiameter ratio of these should result in table2 col3 how to do this?Maybe someone can understand what you are saying here, but I can't.
how can i store this setdata in some variable so can use in other column calculations ?
You just stored it in
table1->index(i, 8). So you can retrieve it fromtable1->index(i, 8).data().[BTW:
i <= maxI: shouldn't this bei < maxI?] -
in table2 column 1&2 are combobox delegate and values are from table1 column1
so when user select in table2 column 1 &2 -input1 input2 or input2/3 so in table2 column 3 there will division of column6 table1(pitchdiameter) value (row 1 /row 2 value)
eg. if in table2 user select input1 input 3 in column1 &2 so now in column 3 result (ratio )is table1 col6 (row 1 /row 3 value)
if in table2 user select input2 input 3 in column1 &2 so now in column 3 result (ratio )is table1 col6 (row 2/row 3 value)
if in table2 user select input1 input 2 in column1 &2 so now in column 3 result (ratio )is table1 col6 (row 1/row 2 value)
