Making a QTableWidget Editable

[llemes4011]

Hello,

I am working with a QTableWidget the user will enter data into, but I cannot get the cells to become editable. Right now I'm doing the following:

void MyClass::initTable(){
// Add Cell 1
  QTableWidgetItem *item = new QTableWidgetItem;
  item->setFlags(item->flags() & ~Qt::ItemIsEditable);
  item->setData(Qt::DisplayRole, "(0,0)");
  tableWidget->setItem(0,0,item);
// Add Cell 2
  item = new QTableWidgetItem;
  item->setFlags(item->flags() & ~Qt::ItemIsEditable);
  item->setData(Qt::DisplayRole, "(1,0)");
  tableWidget->setItem(1,0,item);
 
  tableWidget->setEditTriggers(QAbstractItemView::AllEditTriggers);
}

void MyClass::initTable(){
// Add Cell 1
  QTableWidgetItem *item = new QTableWidgetItem;
  item->setFlags(item->flags() & ~Qt::ItemIsEditable);
  item->setData(Qt::DisplayRole, "(0,0)");
  tableWidget->setItem(0,0,item);
// Add Cell 2
  item = new QTableWidgetItem;
  item->setFlags(item->flags() & ~Qt::ItemIsEditable);
  item->setData(Qt::DisplayRole, "(1,0)");
  tableWidget->setItem(1,0,item);

  tableWidget->setEditTriggers(QAbstractItemView::AllEditTriggers);
}

To copy to clipboard, switch view to plain text mode 

This is just an example, but it shows what I'm trying to do. I also have an Editor that's being applied to QColor objects that are inserted into the table. I don't know if that would change how it functions, but I figured it wouldn't hurt to mention. It's the Editor that's straight out of the Qt Tutorials.

Also, every other time I've tried to enter data into a table, it has worked. but not for this project. I don't know if it's the current version of Qt or what...

Thanks =)

Why do you set the items to not editable when you want them to be editable?

Try using

item->setFlags(item->flags() | Qt::ItemIsEditable);

item->setFlags(item->flags() | Qt::ItemIsEditable);

Hello again. I know it doesn't make sense to use ~Qt::ItemIsEditable, but it has worked in every other case. I tried I tried replacing the AND with an OR and removing the ~, but it still doesn't work. I tried installing an event filter on the object, but it doesn't seem to recognize my mouse clicks. I gets other events, but not QEvent::MouseButtonPress....

EDIT:
I figured it out. It was the ItemEditor that was eating the events.
I had the following code:

// EDITOR CALLS
    QItemEditorFactory *factory = new QItemEditorFactory;
 
    QItemEditorCreatorBase *colorListCreator =
        new QStandardItemEditorCreator<ColorListEditor>();
 
    factory->registerEditor(QVariant::Color, colorListCreator);
 
    QItemEditorFactory::setDefaultFactory(factory);

// EDITOR CALLS
    QItemEditorFactory *factory = new QItemEditorFactory;

    QItemEditorCreatorBase *colorListCreator =
        new QStandardItemEditorCreator<ColorListEditor>();

    factory->registerEditor(QVariant::Color, colorListCreator);

    QItemEditorFactory::setDefaultFactory(factory);

To copy to clipboard, switch view to plain text mode 

And by doing that, it seemed to have been consuming the events. I have decided to remove the editor, and write a custom delegate to display the combo boxes in only specific columns.

Thanks for all your input =)
