Hello,
I have looked src/osgViewer/GraphicsWindowX11.cpp and it helped to
localise my problem.
I printed the debug info with "osg::notify" in key points of the code
and got very interesting results. Here are key points and results:
case KeyPress:
{
if (firstEventTime==0) firstEventTime = ev.xmotion.time;
Time relativeTime = ev.xmotion.time - firstEventTime;
eventTime = baseTime + static_cast<double>(relativeTime)*0.001;
//!!!!!!!!!!!!
_modifierState = ev.xkey.state;
osg::notify(osg::INFO)<<"+++ev.xkey.keycode = "<< ev.xkey.keycode <<
std::endl;
keyMapSetKey(_keyMap, ev.xkey.keycode);
int keySymbol = 0;
adaptKey(ev.xkey, keySymbol);
getEventQueue()->keyPress(keySymbol, eventTime);
osg::notify(osg::INFO)<<"+++key = "<<
keySymbol << " press !" << std::endl;
break;
}
results:
ey= 97
+++ev.xkey.keycode = 38
+++key = 97 press !
key= 97
+++ev.xkey.keycode = 39
+++key = 115 press !
key= 115
+++ev.xkey.keycode = 40
+++key = 100 press !
key= 100
+++ev.xkey.keycode = 40
+++key = 100 press !
key= 100
+++ev.xkey.keycode = 40
+++key = 100 press !
key= 100
+++ev.xkey.keycode = 64
+++key = 65513 press !
key= 65513
+++ev.xkey.keycode = 50
+++key = 65505 press !
key= 65505
----------------------------------------------------------here I
switched the keyboard layout --
+++ev.xkey.keycode = 39
+++key = 0 press !
key= 0
+++ev.xkey.keycode = 40
+++key = 0 press !
key= 0
+++ev.xkey.keycode = 38
+++key = 0 press !
key= 0
+++ev.xkey.keycode = 38
+++key = 0 press !
key= 0
+++ev.xkey.keycode = 25
+++key = 0 press !
key= 0
+++ev.xkey.keycode = 25
+++key = 0 press !
key= 0
+++ev.xkey.keycode = 25
+++key = 0 press !
key= 0
+++ev.xkey.keycode = 25
+++key = 0 press !
key= 0
+++ev.xkey.keycode = 40
+++key = 0 press !
key= 0
I continued my research :). But the next problem I crossed with, was
the following function (GraphicsWindowX11::adaptKey). I'm not very
competent in Linux coding, and I get confused with conversion into
ASCII, because national characters have another ASCII codes. There is
an ASCII code before conversion and therу isn't after it. (see output
results above). I'd be glad to any help :)
void GraphicsWindowX11::adaptKey(XKeyEvent& keyevent, int& keySymbol)
{
Display* display = _eventDisplay;
unsigned char keybuf[32];
XLookupString( &keyevent, (char *)keybuf, sizeof(keybuf), NULL, NULL );
KeySym ks = XKeycodeToKeysym( display, keyevent.keycode, 0 );
int remappedKey = remapX11Key(ks);
if (remappedKey & 0xff00)
{
// special keyboard character
keySymbol = remappedKey;
}
else
{
// normal ascii key
keySymbol = keybuf[0];
}
}
