[anafor2004]

Hi every body , i try to learn qkeypressed function, if somebody any keypress my program try to detect it. But I think i made a mistake. Can you help me?

(main.h)

#include "ui_main.h"
#include  "dialog1.h"
#include <QTranslator>
#include <QKeyEvent>
#include  <QObject>
 
class MainWindow : public QMainWindow, public Ui::MainWindow
{
    Q_OBJECT
public:
 
    int i;
    QTranslator translator;
	 MainWindow(QWidget *parent = 0);
	~MainWindow();
 
 
private:	
    Ui::MainWindow 		ui;
 
 
    void languageChange(int);
 
protected:
		void changeEvent(QEvent* event);
		void keyPressed(QKeyEvent* event);
public slots:
	void english();
	void turkce();
	void deutsch();
	void reset();
	void sayfa();
 };

#include "ui_main.h"
#include  "dialog1.h"
#include <QTranslator>
#include <QKeyEvent>
#include  <QObject>

class MainWindow : public QMainWindow, public Ui::MainWindow
{
    Q_OBJECT
public:
	
    int i;
    QTranslator translator;
	 MainWindow(QWidget *parent = 0);
	~MainWindow();
	

private:	
    Ui::MainWindow 		ui;
    
    
    void languageChange(int);
 
protected:
		void changeEvent(QEvent* event);
		void keyPressed(QKeyEvent* event);
public slots:
	void english();
	void turkce();
	void deutsch();
	void reset();
	void sayfa();
 };

To copy to clipboard, switch view to plain text mode 

from cpp file

void MainWindow::keyPressed(QKeyEvent* event)
 {
	 ui.label_2->setText(QString("*"));
 
 }

void MainWindow::keyPressed(QKeyEvent* event)
 {
	 ui.label_2->setText(QString("*"));
	 
 }

To copy to clipboard, switch view to plain text mode 

but it doent show me a " * " on my label_2

it should be

void keyPressEvent(QKeyEvent *e)

void keyPressEvent(QKeyEvent *e)

To copy to clipboard, switch view to plain text mode
