    Unhappy Table View not Updating after adding a new Row

    Hey Folks !

    Hope you all are doing well.

    I have been through a lot of similar links regarding the question but yet i didn't found any perfect solution regarding that. Here's my code :

    Qt Code:
    1. // Called this in constructor
    2. model = new QStandardItemModel(0,0,this);
    4. // this is the logic of showing the view for Table View
    5. tableView = new QTableView(this);
    6. tableView->setModel(model);
    7. tableView->verticalHeader()->setVisible(false);
    8. tableView->verticalHeader()->setDefaultSectionSize(10);
    10. for(int i = 0; i < clusterNames.length(); i++) {
    11. QStandardItem *clusterName_i = new QStandardItem(clusterNames[i]);
    12. QStandardItem *clusterIP_i = new QStandardItem(clusterIPs[i]);
    14. model->setItem(i, 0, clusterName_i);
    15. model->setItem(i, 1, clusterIP_i);
    16. }
    18. tableView->viewport()->update();
    To copy to clipboard, switch view to plain text mode 

    Logic/Explanation : The logic which i am doing behind this functionality as i populate a QDialog on a button and the data which i insert on the opened Dialog which is of different class. After adding the values i close that dialog and noticed that Tree & Table View aren't updating automatically but when i close that window and reopened it i saw it with updated values.

    If anyone have suggestions or the solution that would be a great help for me.

    Thanks In Advance

    Default Re: Table View not Updating after adding a new Row

    The view should update automatically if the model changes.

    Maybe check if you are updating a different model than the one you are showing.
