How to create dependency between 2 columns using combobox delegates in MVC

[uzairsaeed702]

Here you go, run this code.

I used delegate (because I used standard model) but you could do the similar in the your custom model.

QModelIndex nextColumnIndex = model->index(index.row(), 1);

QModelIndex nextColumnIndex = model->index(index.row(), 1);

To copy to clipboard, switch view to plain text mode 

Santosh Reddy thanks alot for the code but in custom model its difficult to examine the problem .Your hint for AbstractItemModel::createIndex worked like charm !!! . I have just inserted two line of code in model and few lines of code in my delegate class and work done.

QModelIndex changeRequest =  createIndex(row,4);
setData(changeRequest ,Qt::EditRole);

QModelIndex changeRequest =  createIndex(row,4);
setData(changeRequest ,Qt::EditRole);

To copy to clipboard, switch view to plain text mode 

Above was my modification ,

Thanks again Santosh
