Hi Sebastian,
I have almost completed the example. My original implementation is a little bit
complex than this. Thanks to the couple of private replies and discussion, I
will post it tomorrow.
But for keyboard inputs, I'm using an event filter.
Something like this:
Code:
class QInputFilter : public QObject
{
Q_OBJECT
protected:
bool eventFilter(QObject *obj, QEvent *event);
void onKeyPress(QKeyEvent *e);
void onKeyRelease(QKeyEvent *e);
};
bool QInputFilter::eventFilter(QObject *obj, QEvent *event)
{
switch(event->type())
{
case QEvent::KeyPress:
onKeyPress(static_cast<QKeyEvent *>(event));
break;
case QEvent::KeyRelease:
onKeyRelease(static_cast<QKeyEvent *>(event));
break;
}
return QObject::eventFilter(obj, event);
}
void QInputFilter::onKeyPress(QKeyEvent *e)
{
if(e->isAutoRepeat())
{
e->ignore();
return;
}
unsigned int key = e->key();
// add pressed keys and add changed keys for current frame
// renderwidget will clear changed keys at the end of frame
Input::PrivateAccess::pressedKeys().insert(key);
Input::PrivateAccess::changedKeys().insert(key);
e->accept();
}
void QInputFilter::onKeyPress(QKeyEvent *e)
{
if(e->isAutoRepeat())
{
e->ignore();
return;
}
unsigned int key = e->key();
// remove released keys and add changed keys for current frame
// renderwidget will clear changed keys at the end of frame
Input::PrivateAccess::pressedKeys().erase(e->key());
Input::PrivateAccess::changedKeys().insert(e->key());
e->accept();
}
Add input listener to your Qt app:
Code:
sdt::Author::QInputFilter inputFilter;
app.installEventFilter(&inputFilter);
I have almost fully static Input class to access keys and mouse states during
each frame (paintGL()) I've actually tried to implement Unity3D like approach
so inside cull or update traversal I can use Input::getButton(),
Input::getKey(), Input::isKeyUp(), etc. methods.
I can add full implemention of this to my full example.
Cheers,
Can
