How to get key information from qt terminal to gnuplot

[Tatsuro M. <tma...@ya...>]

Hello

http://gnuplot.10905.n7.nabble.com/Spacebar-does-not-raise-command-window-with-wxt-terminal-td18540.html


For qt terminal, this feature seems not to be implemented. (Right?)
Although I do not have enough knowledge, I tried to implement it.
I looked into qt_term.cpp and QtGnuplotScene.cpp.

In QtGnuplotScene.cpp, qt terminal seems to return key information in 

void QtGnuplotScene::keyPressEvent(QKeyEvent* event)
<snip>
live = m_eventHandler->postTermEvent(GE_keypress,
int(m_lastMousePos.x()), int(m_lastMousePos.y()), key, 0, m_widget);

While in qt_term.cpp,

/*-------------------------------------------------------
 * Communication terminal -> gnuplot
 *-------------------------------------------------------*/

bool qt_processTermEvent(gp_event_t* event)
<snip>
if ((event->type == GE_keypress) && (paused_for_mouse & PAUSE_KEYSTROKE) && (event->par1 > '\0'))


However,
'struct gp_event_t' has no member named 'key'


How I do get key information from qt terminal to gnuplot?

Thank you in advance.
