For this purpose you need implement Qtitan::GridTableColumnEditor and assign it to Qtitan::GridTableColumn. See example below:

main.cpp
#include <QApplication>
#include "window.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Window w;
    w.show();
    return a.exec();
}

window.h
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QtitanGrid.h>

class Window : public QMainWindow
{
    Q_OBJECT
public:
    Window();
 private:
    Qtitan::Grid* m_grid;
};

class MyColumnEditor : public Qtitan::GridTableColumnEditor
{
    Q_OBJECT
public:
    MyColumnEditor();
    virtual QWidget* createEditorWidget(Qtitan::GridColumnBase* column);
private Q_SLOTS:
    void editChanged(const QString &);
private:
};
#endif // MAINWINDOW_H

window.cpp
#include <QStandardItemModel>

#include "window.h"

Window::Window()
: QMainWindow()
{
    setWindowTitle(tr("QtitanDataGrid Demo"));
    setGeometry(200, 250, 1200, 800);

    m_grid = new Qtitan::Grid();
    m_grid->setViewType(Qtitan::Grid::TableView);
    Qtitan::GridTableView* view = m_grid->view<Qtitan::GridTableView>();
    view->options().setColumnHeight(35);

    QStandardItemModel* model =  new QStandardItemModel(4, 4);
    for (int row = 0; row < 4; ++row)
    {
        for (int column = 0; column < 4; ++column)
        {
            QStandardItem *item = new QStandardItem(QString("row %0, column %1").arg(row).arg(column));
            model->setItem(row, column, item);
        }
    }
    view->setModel(model);

    MyColumnEditor* editor = new MyColumnEditor();
    Qtitan::GridTableColumn* column = (Qtitan::GridTableColumn *)view->getColumn(0);
    column->setColumnEditor(editor);

    setCentralWidget(m_grid);
}

/* MyColumnEditor */
MyColumnEditor::MyColumnEditor()
    : Qtitan::GridTableColumnEditor()
{
}

QWidget* MyColumnEditor::createEditorWidget(Qtitan::GridColumnBase* column)
{
    Q_UNUSED(column);
    QLineEdit* edit = new QLineEdit();
    connect(edit, SIGNAL(textEdited(const QString &)), this, SLOT(editChanged(const QString &)));
    return edit;
}

void MyColumnEditor::editChanged(const QString &)
{
}

Thanks for the reply,
I think you did not understood my question.
I want to make grid header editable on double click of grid header column and set edited value on header column after finishing edit operation.
Please let us know how to do that?

Unfortunately, at the moment there is no such feature (ability to edit header text).
