Problem with new QTableWidgetItem

[jacks916]

you may have to format it more like this so that you can access the item later.

ui.table->setItem( row , 0, new QTableWidgetItem() );
ui.table->item(row , 0 )->setText(QString( "%1" ).arg( num ) );
ui.table->item(row, 0 )->setBackgroundColor( QColor(178,34,34) );

ui.table->setItem( row , 0, new QTableWidgetItem() );
ui.table->item(row , 0 )->setText(QString( "%1" ).arg( num ) );
ui.table->item(row, 0 )->setBackgroundColor( QColor(178,34,34) );

To copy to clipboard, switch view to plain text mode 

Something I found out after hours of invalid pointer access

Perfect.
That's what I needed.

Thanks.

Where do you allocate space to hold the array of QTableWidgetItem pointers? If you never do that then this a recipe for serious crashing. Using a QList<QTableWidgetItem*> or QVector<QTableWidgetItem*> is a far safer option.

Chris was that to me?

They get held into the QTableWidget, I just reference them in the row and col of the table ( item( row, col) ), for my application they work fine, no issues, and no risk. They only get replaced when i say so.

No, it was for the OP.
