[Qt-interest] Expanding view items in a window

[Chris Meyer]

In the code below, how do I get the QTableView to expand to fill the
available space?

(This project can be easily place into a new project using Qt Creator
by creating a new "Qt4 Gui Application" project based on a QWidget and
unchecking the 'generate form' at the appropriate point. Then replace
widget.cpp with this code.)

#include "widget.h"

#include <QAbstractTableModel>
#include <QVBoxLayout>
#include <QLabel>
#include <QTableView>
#include <QHeaderView>

class MyTableModel : public QAbstractTableModel
{
public:
    virtual int rowCount(const QModelIndex &parent) const;
    virtual int columnCount(const QModelIndex &parent) const;
    virtual QVariant headerData (int section, Qt::Orientation
orientation, int role ) const;
    QVariant data(const QModelIndex &index, int role) const;
};

Widget::Widget(QWidget *parent)
    : QWidget(parent)
{
    setMinimumSize(400,200);
    QVBoxLayout *layout = new QVBoxLayout(this);
    layout->addWidget(new QLabel(tr("My table:")));
    QTableView *table_view = new QTableView();
    table_view->setModel(new MyTableModel());
    table_view->setAlternatingRowColors(true);
    table_view->verticalHeader()->hide();
    layout->addWidget(table_view);
}

Widget::~Widget()
{
}

int MyTableModel::rowCount(const QModelIndex &parent) const
{
    if (parent.isValid())
        return 0;
    return 2;
}

int MyTableModel::columnCount(const QModelIndex &parent) const
{
    if (parent.isValid())
        return 0;
    return 2;
}

QVariant MyTableModel::headerData (int section, Qt::Orientation
orientation, int role ) const
{
    if (role == Qt::DisplayRole && orientation == Qt::Horizontal)
    {
        if (section == 0)
            return tr("Column 1");
        else if (section == 1)
            return tr("Column 2");
    }

    return QVariant();
}

QVariant MyTableModel::data(const QModelIndex &index, int role) const
{
    if (role == Qt::DisplayRole)
    {
        return 100 + index.column() * 10 + index.row();
    }

    return QVariant();
}
