Hi want to add a new Q_PROPERY into my subclass and use this in my application.

I tried the following test programe.

Scenario 1:
1. created the following class as a subclass of QPushButton.

class eSSlButtonublic QPushButton
{
Q_OBJECT
// Q_PROPERTY(char val READ getVal)
public:
eSSlButton(QWidget * parent = 0);
~eSSlButton();
void keyPressEvent( QKeyEvent *e );
};

definition for the above class

eSSlButton::eSSlButton(QWidget * parent):QPushButton(parent)
{

}

void eSSlButton::keyPressEvent( QKeyEvent *e )
{

printf("In side dbasbd %c %x\n",QObject:roperty("val").toChar(),e->key());
}

eSSlButton::~eSSlButton()
{

}

2. Now added the properties 'val' as char type from property window of Qt Designer.

3. Now when I run the executable it gives a segmentation fault.


Kindly let me know how to set the dynamic property for the subclass with the help of QT Designer.

Thanks in Advance
