signals for key presses ?

i have a QWidget object and want to add handlers for some key presses, the traditional way
is to inherit QWidget and reimplement the virtual funcitons, my question is: can i add
event handlers without inheriting QWidget ?
is there signals for keyboard events ?:confused:

you can set event filter on you widget and process QKeyEvent.
take a look at QObject::installEventFilter and QObject::eventFilter.

Thank you,this solution is based on inheriting QObject, but i don't want to use inheritance.

what do you want to achive? give us more information.

here is the code:

Code:

---

int main(int argc,char** args)
{
        QApplication a(argc, argv);
	QSplitter* splitter = new QSplitter();
 
	QDirModel* model = new QDirModel();
	QTreeView* tree = new QTreeView(splitter);
	tree->setModel(model);
	tree->setRootIndex( model->index( QDir::currentPath() ) );
 
	QListView* lview = new QListView(splitter);
	lview->setModel(model);
	lview->setRootIndex( model->index(QDir::currentPath()) );
 
        QStringList* stringList = new QStringList( QString("item 0") );
	for (int i = 1;i<10;i++)
		stringList->append( QString("item %1").arg(i) );
 
	StringListModel* myCustomModel = new StringListModel(*stringList);
	QTreeView* view3 = new QTreeView(splitter);
	view3->setModel(myCustomModel);	
 
	splitter->show();
 
	return a.exec();
}

as i press enter i want to add new string to stringList and reflect the changes to the view.

I don't see a problem. create a new widget and put your splitter on it, then install event filter on needed widget and process key event.

Yes i tried it and it works, thank you. :)
