Align right a column of QTableView

Kamar

Hi,

First thing, sorry for my bad english and i hope you'll understand my issue;
I am newbie in QT and I'm really stuck that's why I ask you to help me
I have a Qtableview in Logista.cpp which I fill like this:

QSqlQueryModel * modalStockRec= new QSqlQueryModel();
        QSqlQuery QryTabStockRec;
        QryTabStockRec.exec("select codvar 'Variété',CAST(sum(pdsfru) as signed integer) as 'Tout-Venant', \
            if(frigo='N' and deverdi='N' and etat='R', cast(sum(pdsfru) as signed integer) ,0) as Arrivage, \
            if(frigo='O' and deverdi='N' and etat='F', cast(sum(pdsfru) as signed integer) ,0) as Frigo, \
            if(frigo='N' and deverdi='O' and etat='F', cast(sum(pdsfru) as signed integer),0)  as Deverdissage, \
            if((frigo='O' or deverdi='O') and etat='R', cast(sum(pdsfru) as signed integer),0 )  as Ressuyage \
            from palbrut where numver=0 group by 1;");
        modalStockRec->setQuery(QryTabStockRec);
        ui->TabStockRec->setModel(modalStockRec);

I created a Class to align the QTableView
stylingproxymodel.h :

#ifndef STYLINGPROXYMODEL_H
#define STYLINGPROXYMODEL_H
 
#include <QObject>
#include <QIdentityProxyModel>
#include <QModelIndex>
#include <QObject>
 
 
class StylingProxyModel : public QIdentityProxyModel
{
  QVariant data(const QModelIndex &index, int role) const
  {
    if (role != Qt::TextAlignmentRole)
      return QIdentityProxyModel::data(index, role);
 
    return Qt::AlignCenter;
  }
 
public :
  StylingProxyModel();
};
 
#endif // STYLINGPROXYMODEL_H

stylingproxymodel.cpp :

#include "stylingproxymodel.h"
 
StylingProxyModel::StylingProxyModel()
{
 
}

I don't know if i do it right, if not correct me please
Now i want to link this class with the QTableView
Help me please :(
Thank you

I'll post a code snippet of mine in which I set all kind of parameters. I should tell I am using 5 exact same table widgets called monitors

for(QTableWidget* monitor : monitors){
       monitor->setRowCount(16);
       monitor->setColumnCount(40);
       monitor->setShowGrid(false);
       monitor->horizontalHeader()->hide(); // requires #include <QHeaderView>
       monitor->verticalHeader()->hide();
       monitor->rowHeight(5);
       monitor->columnWidth(5);
       monitor->horizontalHeader()->setDefaultSectionSize(23);
       monitor->verticalHeader()->setDefaultSectionSize(29);
       monitor->horizontalHeader()->setSectionResizeMode(QHeaderView::Fixed);
       monitor->verticalHeader()->setSectionResizeMode(QHeaderView::Fixed);
       monitor->setDisabled(true);
   }

  for(int j = 0; j < 16; j++) {
       for(int k= 0; k < 40; k++) {
           for(int i = 0; i < 5; i++) {
               column[i] = k;
               row[i] = j;
               monitors[i]->model()->setData(monitors[i]->model()->index(row[i],column[i]),QBrush(Qt::green),Qt::ForegroundRole);
               monitors[i]->item(row[i],column[i])->setTextAlignment(Qt::AlignCenter); // < alignment code can also AlignRight
           }
      }
   }

This code is situated in the setup of my Mainwindow.cpp file I did not make a separate class for it, so I hope you can find something usefulls in it. Good luck!

Given QSqlQueryModel is write only you need a proxy model on top of it. This one: https://pastebin.com/gmNCuUFk is a proxy model that adds a writeable layer on top of a flat (i.e. not a tree) model.

now you can call setData(index,Qt::AlignCenter,Qt::TextAlignmentRole); to set it however you want it
