Hi Legeo
I had a similar problem - using osg, qt4 and the AdapterWidget example.
In AdapterWidget::keypressEvent (...)
osgGA::GUIEventAdapter::KeySymbol) * (event->text().toAscii().data() returns
0 in the call
_gw->getEventQueue()->keyPress( (... ) ) for keys like:
Qt::Key_up ... Have a look at the Qt documentation Qt::Key.
I have managed it with:
int c = *event->text().toAscii().data();
if ( c == 0)
{
switch (event->key())
{
case Qt::Key_PageDown:
_gw->getEventQueue()->keyPress(
osgGA::GUIEventAdapter::KeySymbol::KEY_Page_Down );
break;
case Qt::Key_PageUp:
_gw->getEventQueue()->keyPress(
osgGA::GUIEventAdapter::KeySymbol::KEY_Page_Up );
break;
case Qt::Key_Up:
_gw->getEventQueue()->keyPress( osgGA::GUIEventAdapter::KEY_Up);
break;
}
}
else
_gw->getEventQueue()->keyPress( (osgGA::GUIEventAdapter::KeySymbol) *
(event->text().toAscii().data() ) );
There might be a better solution but it works.

Subject: [osg-users] osg+QT MODKEY How to
Hi all,
I'm trying to add a Modkey event handler to my application with osg and
qt4. But it seems that the getModKeyMask() fuction fails to work. Return
value of getModKeyMask() always is 0, even if I have a MODKEY pressed. And,
this is my code:
if ( ea.getEventType() == osgGA::GUIEventAdapter::PUSH &&
ea.getButtonMask() ==
osgGA::GUIEventAdapter::LEFT_MOUSE_BUTTON &&
ea.getModKeyMask() == osgGA::GUIEventAdapter::MODKEY_SHIFT )
{
/*---------------------------------------------
do something here
-------------------------------------------------*/
}
How can I handle it? Thanks in advance!
cheers
legeo
