[SOLVED] How to place frozen column on the right side of table

[Mr. Kibu]

I got it!

Here is the picture of the result: http://postimg.org/image/fyh3pwl7h/

I have got tables with many columns and I wanted to freeze one column (e.g. the last one) on the right side of the table-widget. In my case I give a fix width for the frozen column.

Here is the code of my freezetablewidget.cpp:

#include "freezetablewidget.h"

#include <QScrollBar>
#include <QHeaderView>

FreezeTableWidget::FreezeTableWidget(QAbstractItemModel * model)
{
      setModel(model);
      //setColumnHidden(model->columnCount()-1,true); // hide the last column
      frozenTableView = new QTableView(this);

      init();

      //connect the headers and scrollbars of both tableviews together

//      connect(horizontalHeader(),SIGNAL(sectionResized(int,int,int)), this,
//              SLOT(updateSectionWidth(int,int,int)));
      connect(verticalHeader(),SIGNAL(sectionResized(int,int,int)), this,
              SLOT(updateSectionHeight(int,int,int)));

      connect(frozenTableView->verticalScrollBar(), SIGNAL(valueChanged(int)),
              verticalScrollBar(), SLOT(setValue(int)));
      connect(verticalScrollBar(), SIGNAL(valueChanged(int)),
              frozenTableView->verticalScrollBar(), SLOT(setValue(int)));


}

FreezeTableWidget::~FreezeTableWidget()
{
      delete frozenTableView;
}

void FreezeTableWidget::init()
{
      frozenTableView->setModel(model());
      frozenTableView->setFocusPolicy(Qt::NoFocus);
      frozenTableView->verticalHeader()->hide();
      frozenTableView->horizontalHeader()->setSectionResizeMode(QHeaderView::Fixed);

      viewport()->stackUnder(frozenTableView);


      frozenTableView->setStyleSheet("QTableView { border: none;"
                                     "background-color: #8EDE21;"
                                     "selection-background-color: #999}"); //for demo purposes
      frozenTableView->setSelectionModel(selectionModel());

      for (int col = 0; col < model()->columnCount()-1; ++col) // ! hide all other but NOT last
                frozenTableView->setColumnHidden(col, true);

      frozenTableView->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
      frozenTableView->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
      frozenTableView->show();

      updateFrozenTableGeometry();

      setHorizontalScrollMode(ScrollPerPixel);
      setVerticalScrollMode(ScrollPerPixel);
      frozenTableView->setVerticalScrollMode(ScrollPerPixel);
}


void FreezeTableWidget::updateSectionWidth(int logicalIndex, int /* oldSize */, int newSize)
{
//      if (logicalIndex == 0){
//            frozenTableView->setColumnWidth(0, newSize);
//            updateFrozenTableGeometry();
//      }
}

void FreezeTableWidget::updateSectionHeight(int logicalIndex, int /* oldSize */, int newSize)
{
      frozenTableView->setRowHeight(logicalIndex, newSize);
}

void FreezeTableWidget::resizeEvent(QResizeEvent * event)
{
      QTableView::resizeEvent(event);
      updateFrozenTableGeometry();
 }

QModelIndex FreezeTableWidget::moveCursor(CursorAction cursorAction,
                                          Qt::KeyboardModifiers modifiers)
{
//      QModelIndex current = QTableView::moveCursor(cursorAction, modifiers);

//      if (cursorAction == MoveLeft && current.column() > 0
//              && visualRect(current).topLeft().x() < frozenTableView->columnWidth(0) ){
//            const int newValue = horizontalScrollBar()->value() + visualRect(current).topLeft().x()
//                                 - frozenTableView->columnWidth(0);
//            horizontalScrollBar()->setValue(newValue);
//      }
//      return current;
}

void FreezeTableWidget::scrollTo (const QModelIndex & index, ScrollHint hint){
//    if (index.column() > 0)
//        QTableView::scrollTo(index, hint);
}


void FreezeTableWidget::updateFrozenTableGeometry()
{

    frozenTableView->setGeometry(horizontalHeader()->width()-73 ,frameWidth(), 100,viewport()->height()+horizontalHeader()->height());

}

Thank you to mrjj for your help!!
