Model, view, resize to show all data

[jcr]

Hello,
The constructor is like this:

Test::Test(QWidget* parent)
  : QWidget(parent)
{
  //Model
  QDirModel* model = new QDirModel;
  QModelIndex parentIndex = model->index(QDir::currentPath());
  //text
  text = new QTextEdit;  
  int row = model->rowCount(parentIndex);
  int col = model->columnCount(parentIndex);
  for(int i(0); i<row; ++i)
    for(int j(0); j<col; ++j)
    {
      QModelIndex index = model->index(i, j, parentIndex);
      text->append(model->data(index, Qt::DisplayRole).toString());
    }
  //view
  view = new QTableView;
  view->setModel(model);
  view->setRootIndex(parentIndex);
  //splitter
  splitter = new QSplitter(this);
  splitter->addWidget(text);
  splitter->addWidget(view);
}

Test::Test(QWidget* parent)
  : QWidget(parent)
{
  //Model
  QDirModel* model = new QDirModel;
  QModelIndex parentIndex = model->index(QDir::currentPath());
  //text
  text = new QTextEdit;  
  int row = model->rowCount(parentIndex);
  int col = model->columnCount(parentIndex);
  for(int i(0); i<row; ++i)
    for(int j(0); j<col; ++j)
    {
      QModelIndex index = model->index(i, j, parentIndex);
      text->append(model->data(index, Qt::DisplayRole).toString());
    }
  //view
  view = new QTableView;
  view->setModel(model);
  view->setRootIndex(parentIndex);
  //splitter
  splitter = new QSplitter(this);
  splitter->addWidget(text);
  splitter->addWidget(view);
}

To copy to clipboard, switch view to plain text mode 

How can I make sure that the text, view, and splitter will resize automatically to display all the data?
Many thanks in advance.

Set a layout for that Test widget or subclass the QSplitter instead of QWidget.

Jacek,
Thanks; things are starting to look good:

Test::Test(QWidget* parent)
  : QWidget(parent)
{
  QHBoxLayout* mainLayout = new QHBoxLayout(this);
  //Model
  QDirModel* model = new QDirModel;
  QModelIndex parentIndex = model->index(QDir::currentPath());
  //text
  QTextEdit* text;
  text = new QTextEdit;  
  int row = model->rowCount(parentIndex);
  int col = model->columnCount(parentIndex);
  for(int i(0); i<row; ++i)
    for(int j(0); j<col; ++j)
    {
      QModelIndex index = model->index(i, j, parentIndex);
      text->append(model->data(index, Qt::DisplayRole).toString());
    }
  //view
  QAbstractItemView* view = new QTableView;
  view->setModel(model);
  view->setRootIndex(parentIndex);
  //splitter
  QSplitter* splitter = new QSplitter;
  mainLayout->addWidget(splitter);
  splitter->addWidget(text);
  splitter->addWidget(view);  
  QList<int> list;
  list << 1000 << 1000;
  splitter->setSizes(list);
}

Test::Test(QWidget* parent)
  : QWidget(parent)
{
  QHBoxLayout* mainLayout = new QHBoxLayout(this);
  //Model
  QDirModel* model = new QDirModel;
  QModelIndex parentIndex = model->index(QDir::currentPath());
  //text
  QTextEdit* text;
  text = new QTextEdit;  
  int row = model->rowCount(parentIndex);
  int col = model->columnCount(parentIndex);
  for(int i(0); i<row; ++i)
    for(int j(0); j<col; ++j)
    {
      QModelIndex index = model->index(i, j, parentIndex);
      text->append(model->data(index, Qt::DisplayRole).toString());
    }
  //view
  QAbstractItemView* view = new QTableView;
  view->setModel(model);
  view->setRootIndex(parentIndex);
  //splitter
  QSplitter* splitter = new QSplitter;
  mainLayout->addWidget(splitter);
  splitter->addWidget(text);
  splitter->addWidget(view);  
  QList<int> list;
  list << 1000 << 1000;
  splitter->setSizes(list);
}

To copy to clipboard, switch view to plain text mode 

But the "text" and "view" boxes of the splitter are of the same size. I would like their sizes to adjust automatically to the amount of data that needs to be displayed so that scroll bars would not be needed. I tried to play with the setSizes function but without luck.
