Multiple keys

[Daoudou]

Hello

i want to know how can i get multiple key, for example :
hold ctrl key and a pressed : ctrkl + a

do you think i'm in the good way ?

`bool KeyEventCamera::handle(const osgGA::GUIEventAdapter& ea, osgGA::GUIActionAdapter& aa)
{
#define PRINT(mask) osg::notify(osg::NOTICE)<<#mask<<" ="<<(ea.getModKeyMask() & mask)<<std::endl;

switch (ea.getEventType())
{
case osgGA::GUIEventAdapter::KEYDOWN:
	if (ea.getModKeyMask() && osgGA::GUIEventAdapter::MODKEY_CTRL)
	{
		if (ea.getKey() == 'a')
		{
			std::cout << "A key pressed" << "\n";
		}
	}
	break;
default:
	break;
}
return false;

}
`

thanks in advance ^^

As far as I know, This may not work for all platforms. Especially, Ctrl+A will generate a different key value under Windows. You may have to capture that special key value instead.

Try using ea.getUnmodifiedKey() rather than ea.getKey().

Thanks .

IT'S WORKS 🤩

if anyone needs it

`bool KeyEventCamera::handle(const osgGA::GUIEventAdapter& ea,
osgGA::GUIActionAdapter& aa)
{
if (!_trackballManipulator) return false;
osg::Matrix matrix;

switch (ea.getEventType())
{
case osgGA::GUIEventAdapter::KEYDOWN:
	if (ea.getModKeyMask() &
		osgGA::GUIEventAdapter::MODKEY_CTRL)
	{
		if (ea.getUnmodifiedKey() == osgGA::GUIEventAdapter::KEY_S) 
		{
			std::cout << "ctrl + s keys pressed" << "\n";
		}
	}
	break;
default:
	break;
}

return false;

}`
