[Solved] How to Handle all the keys in Key Press / Release Event?

Macro

I have a QLabel. In that i am going to handle the Key Press and the Key Release Events. For example. If i am Pressing a key (ex. key Q). the text of the Label should change to "You Pressed Key Q" like that. and if i Release it the Text should be changed to "You Released Key Q". I know how to handle it for a single particular key. Can anyone plz help me how can i do this for the all the keys?

Thanks and Regards..

For a Single Particular key i can do like this,

KeyPress.h

#include <QWidget>
#include <QtGui>

class KeyPress : public QWidget
{
    Q_OBJECT

public:
    KeyPress(QWidget *parent = 0);

protected:
    void keyPressEvent(QKeyEvent *event);
    void keyReleaseEvent(QKeyEvent *event);

private:
    QLabel *myLabelText;
};

KeyPress.cpp

#include <QApplication>
#include <QKeyEvent>
#include "KeyPress.h"

KeyPress::KeyPress(QWidget *parent) :
    QWidget(parent)
{
    myLabelText = new QLabel ("You Didn't Pressed / Released any Key");
}

void KeyPress::keyPressEvent(QKeyEvent *event)
{
    if(event->key() == Qt::Key_Q)
    {
        myLabelText->setText("You Pressed Key Q");
    }
    else
    {
        myLabelText->setText("You Pressed Other Key");
    }
}

void KeyPress::keyReleaseEvent(QKeyEvent *event)
{
    if(event->key() == Qt::Key_Q)
    {
        myLabelText->setText("You Released Key Q");
    }
    else
    {
        myLabelText->setText("You Released Other Key");
    }
}

main.cpp

#include <QtGui/QApplication>
#include "KeyPress.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    KeyPress *keyPress = new KeyPress();
    keyPress->show();

    return a.exec()
}

What about ... ?

void Widget::keyPressEvent(QKeyEvent *ev)
{
    setText("You Pressed Key " + ev->text());
}

void Widget::keyReleaseEvent(QKeyEvent *ev)
{
    setText("You Release Key " + ev->text());
}
