TableView Spinbox HAlignment

Bert59

Hi,

I have a table view to which I provide values as doubles and I get the following.

I would like the values centered in the column. So I created a new delegate and attached it to the TableView.

Now when I edit the values they are centered in the Spinbox, but when they are not edited they are not.

Why are the values only centered in edit mode and how can I keep the values centered?

Hi

I have written the following:
model->setData(index, Qt::AlignCenter, Qt::TextAlignmentRole);

and it works.

Thank you

@Bert59 please provide a MWE(minimal workable example)

It seems that your delegate only sets the editor alignment but not the unedited text, a possible solution is to override the initStyleOption method:

class StyledItemDelegate: public QStyledItemDelegate{
public:
   using QStyledItemDelegate::QStyledItemDelegate;
protected:
    void initStyleOption(QStyleOptionViewItem *option, const QModelIndex &index) const{
        QStyledItemDelegate::initStyleOption(option, index);
        option->displayAlignment = Qt::AlignCenter;
    } 
};

You should take a look at the Qt::TextAlignmentRole

I just have an additionnal question.

How can I make the Spinbox to be displayed even if not in edition mode?

I found openPersistenEditor which seems to work.

Maybe there are othe solutions?

Through a QStyledItemDelegate.
