Hi Robert,
I find some time to dig into this. And here are my observations ( I am
working with Vivien's submission, with osgviewerMFC )
I put break points in GraphicsWindowWin32.cpp:
Line: 2476
case WM_KEYDOWN :
case WM_SYSKEYDOWN :
////////////////////
{
int keySymbol = 0;
Line: 2451
/////////////////
case WM_CHAR :
/////////////////
{
// if event was not handled by WM_KEYDOWN then we take care
of it here
// this method gives directly the utf16 char back so just
need to add it as it is
if(!_keypresshandled)
{
// first check if key is already registered on the map
case WM_KEYDOWN/WM_SYSKEYDOWN : get its chance to handle every single key
you press, even a dead key. So, for my czech character 'č', I have to press:
SHIFT, '+', and 'c', in this order, and for each of these three I get
WM_KEYDOWN. The only difference is that when I complete this sequence, on
top of all WM_KEYDOWNs, it gets to case WM_CHAR: with my 'č'. This is how
the system is managing these events. To reflect this behavior into OSG, only
one single line needs to be added, I think, and that will fix Brad's issue
as well:
else
{
// was no special key, let WM_CHAR handle it
_keypresshandled = false;
_lastkeysymbol = keySymbol;
/* the new line */ getEventQueue()->keyPress(keySymbol, eventTime);
}
This was the key that was waste (being 'eaten' :) ..).
So to me it sounds that, with Vivien's submission, only the dead key +
'something' was not firing an event in osg - for the rest it should work as
before, not as Brad states above that the key events stopped work. I am
very curious what he was actually doing.
Cheers,
-Nick
