[nicky]

Hi all~~ a new guy of Qt. i got a problem about setCursor~~, when pressing mouse button on a label, the cursor cannot be altered by using the function setCursor. Help me!

and why not ?

Check this code..

#include <QApplication>
#include <QLabel>
#include <QMainWindow>
 
 
class CLabel :public QLabel
{
public:
	void mousePressEvent ( QMouseEvent * event );
	void mouseReleaseEvent ( QMouseEvent * event );
};
 
void CLabel::mousePressEvent(QMouseEvent * event )
{
	setCursor(Qt::CrossCursor);
}
 
void CLabel::mouseReleaseEvent(QMouseEvent * event )
{
	setCursor(Qt::ArrowCursor);
}
 
int main (int argc, char *argv[])
{
    QApplication app(argc,argv);
 
   QMainWindow window;
   CLabel label;
   window.setCentralWidget(&label);
 
    window.show(); 
 
    return app.exec();
 
}

#include <QApplication>
#include <QLabel>
#include <QMainWindow>


class CLabel :public QLabel
{
public:
	void mousePressEvent ( QMouseEvent * event );
	void mouseReleaseEvent ( QMouseEvent * event );
};

void CLabel::mousePressEvent(QMouseEvent * event )
{
	setCursor(Qt::CrossCursor);
}

void CLabel::mouseReleaseEvent(QMouseEvent * event )
{
	setCursor(Qt::ArrowCursor);
}

int main (int argc, char *argv[])
{
    QApplication app(argc,argv);
   
   QMainWindow window;
   CLabel label;
   window.setCentralWidget(&label);

    window.show(); 
  
    return app.exec();

}

nicky,
is your question:
when you move the mouse over label then you want to change cursor and when you move away then cursor come to old style?
