Hi All
I've a tool button . i'm adding some action to that toolbutton. when i trigger that action i need some methode to b executed. i did like following.

header file
------------------
QAction *m_action;
actionlist();
 
source file
-----------------------
ui->toolButton->addAction(action);
 
constructor()
{
	    connect(m_action,SIGNAL( triggered()),
            this, SLOT(claamethode()));
}
void actionlist()
{
        m_action = new QAction(m_strTempName,ui->toolButton_3);
	// assiging m_action here
	ui->toolbutton->addaction(m_action);
 
}

header file
------------------
QAction *m_action;
actionlist();

source file
-----------------------
ui->toolButton->addAction(action);

constructor()
{
	    connect(m_action,SIGNAL( triggered()),
            this, SLOT(claamethode()));
}
void actionlist()
{
        m_action = new QAction(m_strTempName,ui->toolButton_3);
	// assiging m_action here
	ui->toolbutton->addaction(m_action);

}
