QTreeWidget signal not working

[Kapil]

Hi...

There is a small problem in it.. whenever i double click on any of my QTreeWIdgetItem, it does not do anything.. infact does not respond to it..
HAve followed all the conventions...
like declaring func in slots and calling the Q_OBJECT...
also i tried to put the arguments as that of signals and slots as same but still it did not work..
i am posting the few lines of code whcih are not wrkin... plz tell what can be the fault in it.. it even does not show me any errors while compiling.. its just that it doesnt work...

QList<QTreeWidgetItem *> widgetList = m_uiMainWindow.routingFlowTree->findItems (QString("Add Design"),Qt::MatchRecursive); 
	if(widgetList.size() != 0)
	{
		QTreeWidgetItem *pAddDesignItem = widgetList.takeFirst();
		QObject::connect(m_uiMainWindow.routingFlowTree, SIGNAL(itemDoubleClicked(*pAddDesignItem , 0)), this, SLOT(onDoubleClickAddDesignItem()));
 
	}

QList<QTreeWidgetItem *> widgetList = m_uiMainWindow.routingFlowTree->findItems (QString("Add Design"),Qt::MatchRecursive); 
	if(widgetList.size() != 0)
	{
		QTreeWidgetItem *pAddDesignItem = widgetList.takeFirst();
		QObject::connect(m_uiMainWindow.routingFlowTree, SIGNAL(itemDoubleClicked(*pAddDesignItem , 0)), this, SLOT(onDoubleClickAddDesignItem()));
		
	}

You may NOT add parameter names or values in SIGNAL and SLOT macros.

SIGNAL(itemDoubleClicked(QTreeWidgetItem*, int))

Hi...

Thanks for the reply,

i want the signal to be emitted when a particular sub item of the QTreeWidget is double clicked.. if i do not add the parameter names then it executes the same slot for any of the items clicked on the Tree Widget .. i want different slots to be executed for different tree widget items clicked...

what do i do for that....
what i tried didnt work...

with regards ,

Use connect for conecting needed item with needed slot

Use connect for conecting needed item with needed slot

Hi..

am doing that only.. just check on the small code which i have put.. this would give u some idea...

// connection
connect(m_uiMainWindow.routingFlowTree, SIGNAL(itemDoubleClicked(QTreeWidgetItem*, int)), this, SLOT(onDoubleClickAddDesignItem(QTreeWidgetItem*, int)));
 
// slot
void Something::onDoubleClickAddDesignItem(QTreeWidgetItem* item, int column)
{
    QList<QTreeWidgetItem *> widgetList = m_uiMainWindow.routingFlowTree->findItems(QString("Add Design"),Qt::MatchRecursive);
 
    if (widgetList.size() > 0 && item == widgetList.takeFirst())
    {
        // do your thing
    }
}

// connection
connect(m_uiMainWindow.routingFlowTree, SIGNAL(itemDoubleClicked(QTreeWidgetItem*, int)), this, SLOT(onDoubleClickAddDesignItem(QTreeWidgetItem*, int)));

// slot
void Something::onDoubleClickAddDesignItem(QTreeWidgetItem* item, int column)
{
    QList<QTreeWidgetItem *> widgetList = m_uiMainWindow.routingFlowTree->findItems(QString("Add Design"),Qt::MatchRecursive);

    if (widgetList.size() > 0 && item == widgetList.takeFirst())
    {
        // do your thing
    }
}
