[.:saeed:.]

Hello every one .
I try to write English carefully. sorry for my English mistakes(probably ):o

In the attached photo you can see that I have a treewidget in the left and a stackedwidget in the right. what is the best solution for connecting them together? Is there better widget instead of stackedwidget ?I want for example when somebody clicks "Interface" item from treewidget the right page is selected from stackedwidget
I have used this code:


void FirewallSettings::on_trew_settings_clicked(QModelI ndex index)
{
int row;
if( index.parent() == QModelIndex())
row = index.row();
else
row = index.parent().row();

int pageNumber = 0;
for( int rowIndex = 0; rowIndex < row; rowIndex++ ){
pageNumber += ui.trew_settings->topLevelItem( rowIndex )->childCount();
pageNumber ++;
}

if( index.parent() != QModelIndex()){
pageNumber += index.row();
pageNumber ++;
}

ui.sckw_settings->setCurrentIndex( pageNumber );
}

But I think this is not the best solution for this situation. Help me please .
thanks

QStackedWidget is a good approach but the code can be much simpler.

QTreeWidgetItem* X::addPage(const QString &name, QWidget *configPage, QTreeWidgetItem *parent = 0) {
QTreeWidgetItem *item = parent ? new QTreeWidgetItem(parent) : new QTreeWidgetItem(treeWidget);
item->setText(0, name);
item->setData(0, Qt::UserRole, configPage);
stackedWidget->addWidget(configPage);
return item;
}
and then:

connect(treeWidget, SIGNAL(itemClicked ( QTreeWidgetItem *, int )), this, SLOT(showConfig(QTreeWidgetItem*)));
// ...
void X::showConfig(QTreeWidgetItem *item) {
QWidget *w = item->data(Qt::UserRole).value<QWidget*>();
if(w) stackedWidget->setCurrentWidget(w);
}
