QTreeWidget clicked signal

[mkkguru]

i too have a getting same problem related to treewidget item signals ,

QTreeWidgetItem  *plc = new QTreeWidgetItem(ui->treeWidget);
     plc->setText(0,QString("PLC %1").arg(i));
 
  if(plc)
    {
     connect(ui->treeWidget,SIGNAL(itemClicked(QTreeWidgetItem *,int)),this,SLOT(plcconfig()));
   }
 
  QTreeWidgetItem *plcItem = new QTreeWidgetItem(plc);
  plcItem->setText(0, tr("CONFIGURATION"));
  plc->addChild(plcItem);
 
 QTreeWidgetItem *cpuconfig = new QTreeWidgetItem(plcItem);
  cpuconfig->setText(0, tr("CPU CONFIGURATION"));
  plcItem->addChild(cpuconfig);
 
  //  if(cpuconfig)
 // {
 //  connect(ui->treeWidget,SIGNAL(itemClicked(QTreeWidgetItem *,int)),this,SLOT(showCPU()));
// }
 
  QTreeWidgetItem *varconfig = new QTreeWidgetItem(plcItem);
  varconfig->setText(0, tr("VARIABLE CONFIGURATION"));
  plcItem->addChild(varconfig);
 
  QTreeWidgetItem *progconfig = new QTreeWidgetItem(varconfig);
  progconfig->setText(0, tr("PROGRAM VARIABLE CONFIGURATION"));
  varconfig->addChild(progconfig);
 
   if(varconfig)
 {
   connect(ui->treeWidget,SIGNAL(itemClicked(QTreeWidgetItem *,int)),this,SLOT(showpvc()));
  }

QTreeWidgetItem  *plc = new QTreeWidgetItem(ui->treeWidget);
     plc->setText(0,QString("PLC %1").arg(i));

  if(plc)
    {
     connect(ui->treeWidget,SIGNAL(itemClicked(QTreeWidgetItem *,int)),this,SLOT(plcconfig()));
   }

  QTreeWidgetItem *plcItem = new QTreeWidgetItem(plc);
  plcItem->setText(0, tr("CONFIGURATION"));
  plc->addChild(plcItem);

 QTreeWidgetItem *cpuconfig = new QTreeWidgetItem(plcItem);
  cpuconfig->setText(0, tr("CPU CONFIGURATION"));
  plcItem->addChild(cpuconfig);

  //  if(cpuconfig)
 // {
 //  connect(ui->treeWidget,SIGNAL(itemClicked(QTreeWidgetItem *,int)),this,SLOT(showCPU()));
// }

  QTreeWidgetItem *varconfig = new QTreeWidgetItem(plcItem);
  varconfig->setText(0, tr("VARIABLE CONFIGURATION"));
  plcItem->addChild(varconfig);

  QTreeWidgetItem *progconfig = new QTreeWidgetItem(varconfig);
  progconfig->setText(0, tr("PROGRAM VARIABLE CONFIGURATION"));
  varconfig->addChild(progconfig);

   if(varconfig)
 {
   connect(ui->treeWidget,SIGNAL(itemClicked(QTreeWidgetItem *,int)),this,SLOT(showpvc()));
  }

As iam using above signal when iam cliicking on PROGRAM VARIABLE CONF..... the required window has to opened as below.

void ECLogic::showpvc( )
{
    QTabBar *tab_4=new QTabBar(ui->widgetConf);
      PCD= new programvariableconfiguration(tab_4);
      PCD->setWindowTitle(QString("PVC"));
      tabwidget3->insertTab(0,tab_4,QString("PVC"));
      tab_4->setCurrentIndex(tabwidget3->indexOf(ui->widgetConf));
      tab_4->setTabsClosable(true);
      tab_4->setEnabled(true);
      PCD->show();
}

void ECLogic::showpvc( )
{
    QTabBar *tab_4=new QTabBar(ui->widgetConf);
      PCD= new programvariableconfiguration(tab_4);
      PCD->setWindowTitle(QString("PVC"));
      tabwidget3->insertTab(0,tab_4,QString("PVC"));
      tab_4->setCurrentIndex(tabwidget3->indexOf(ui->widgetConf));
      tab_4->setTabsClosable(true);
      tab_4->setEnabled(true);
      PCD->show();
}
