Thank you for the reply!!

I have executed mouselabels demo on qt terminal on Ubuntu 12.04 LTS. 
It partially work. Key input reflected in the plot window. 
However, <del>, <bs> and <esc> work but <tab> does not work. 

For the above fact, Ethan show the thread concering tab key

http://stackoverflow.com/questions/18160051/intercepting-tab-key-press-to-manage-focus-switching-manually

The first answer for the question says that :

Using setFocusPolicy( Qt::NoFocus) property of QWidget, one can set Focus policy on widget which doesn't require tab focus. I thought that I could get tab code using setFocusPolicy( Qt::NoFocus).

Using 
m_widget->setFocusPolicy( Qt::NoFocus);
instead of 
QWidget::setFocusPolicy( Qt::NoFocus);

I could complie QtGnuplotWidget.cpp and got gnuplot_qt.

However, tab key feature does not work on mouselabels demo (demo/mouselabels.dem) on qt term.
Perhaps I have misled the answer of the question.

If you have an idea to tab key to work on the plot window in qt terminal please show the way.
