Problem with QT Treewidgetitem select.

[keyurparekh]

Hi All,

I am beginner in qt. I need help to develop programme using QT. I am using current QT 4.6

I have created treewidget using QT designer. In this tree i have number of items. Now i want to connect only particular item with webpage. I have connect tree widget signal with webpage slot.

But when i click on any member of tree widget it will open same page.

I want that when i click on first item then only web page should open. other wise it should not respond. Below i am posting my code.


Source code

my3::my3(QWidget *parent, Qt::WindowFlags f ) :
QWidget(parent,f)
{
setupUi(this);
ui3 = new my4(this);
stackedWidget->addWidget(ui3);
___qtreewidgetitem1 = treeWidget->topLevelItem(0);
 
___qtreewidgetitem1->setText(0, "Biology");
 
QTreeWidgetItem *___qtreewidgetitem2 = ___qtreewidgetitem1->child(0);
___qtreewidgetitem2->setText(0, QApplication::translate("Form3", "Chapter 1", 0, QApplication::UnicodeUTF8));
QTreeWidgetItem *___qtreewidgetitem3 = treeWidget->topLevelItem(1);
___qtreewidgetitem3->setText(0, QApplication::translate("Form3", "New Item", 0, QApplication::UnicodeUTF8));
QTreeWidgetItem *___qtreewidgetitem4 = treeWidget->topLevelItem(2);
___qtreewidgetitem4->setText(0, QApplication::translate("Form3", "Chemistry", 0, QApplication::UnicodeUTF8));
QTreeWidgetItem *___qtreewidgetitem5 = treeWidget->topLevelItem(3);
___qtreewidgetitem5->setText(0, QApplication::translate("Form3", "Maths", 0, QApplication::UnicodeUTF8));
QTreeWidgetItem *___qtreewidgetitem6 = treeWidget->topLevelItem(4);
___qtreewidgetitem6->setText(0, QApplication::translate("Form3", "Database", 0, QApplication::UnicodeUTF8));
 
 
connect(treeWidget, SIGNAL( itemClicked(QTreeWidgetItem* ,int)),this, SLOT(open_webpage(QTreeWidgetItem*,int)));
 
}
 
void my3::open_webpage(QTreeWidgetItem *item,int column)
{
stackedWidget->setCurrentIndex( stackedWidget->indexOf(ui3));
}

my3::my3(QWidget *parent, Qt::WindowFlags f ) :
QWidget(parent,f)
{
setupUi(this);
ui3 = new my4(this);
stackedWidget->addWidget(ui3);
___qtreewidgetitem1 = treeWidget->topLevelItem(0);

___qtreewidgetitem1->setText(0, "Biology");

QTreeWidgetItem *___qtreewidgetitem2 = ___qtreewidgetitem1->child(0);
___qtreewidgetitem2->setText(0, QApplication::translate("Form3", "Chapter 1", 0, QApplication::UnicodeUTF8));
QTreeWidgetItem *___qtreewidgetitem3 = treeWidget->topLevelItem(1);
___qtreewidgetitem3->setText(0, QApplication::translate("Form3", "New Item", 0, QApplication::UnicodeUTF8));
QTreeWidgetItem *___qtreewidgetitem4 = treeWidget->topLevelItem(2);

QTreeWidgetItem *___qtreewidgetitem5 = treeWidget->topLevelItem(3);
___qtreewidgetitem5->setText(0, QApplication::translate("Form3", "Maths", 0, QApplication::UnicodeUTF8));
QTreeWidgetItem *___qtreewidgetitem6 = treeWidget->topLevelItem(4);
___qtreewidgetitem6->setText(0, QApplication::translate("Form3", "Database", 0, QApplication::UnicodeUTF8));


connect(treeWidget, SIGNAL( itemClicked(QTreeWidgetItem* ,int)),this, SLOT(open_webpage(QTreeWidgetItem*,int)));

}

void my3::open_webpage(QTreeWidgetItem *item,int column)
{
stackedWidget->setCurrentIndex( stackedWidget->indexOf(ui3));
}
