    Hi all,
    In my project i'm using a tree widget.
    Which i created using designer...
    Now i wanted to add checkbox at each child..
    How can i do that?
    My code to create the tree widget as shown below
    @
    #include "dialog.h"
    #include "ui_dialog.h"
    #include <QtCore>
    #include <QtGui>

    Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
    {

    ui->setupUi(this);
    
    ui->treeWidget->setColumnCount(2);
    ui->treeWidget->setHeaderLabels(QStringList()<< "one"<<"two");
    AddRoot("1 first","tree");
    AddRoot("2 second","person");
    AddRoot("3 third","man");
    AddRoot("4 fourth","and last");
    

    }

    Dialog::~Dialog()
    {
    delete ui;
    }
    void Dialog::AddRoot(QString name,QString Description)
    {
    QTreeWidgetItem *itm =new QTreeWidgetItem(ui->treeWidget);
    itm->setText(0,name);
    itm->setText(1,Description);

    AddChild(itm,"one","1111");
    AddChild(itm,"two","2222");
    

    }

    void Dialog::AddChild(QTreeWidgetItem *parent,QString name, QString Description)
    {
    QTreeWidgetItem *itm =new QTreeWidgetItem();
    itm->setText(0,name);
    itm->setText(1,Description);
    parent->addChild(itm);
    }

    void Dialog::on_pushButton_clicked()
    {
    ui->treeWidget->currentItem()->setBackgroundColor(0,Qt::red);

    ui->treeWidget->currentItem()->setBackgroundColor(1,Qt::blue);
    

    }
    @

    here i need check box to select - "one" ,"111"
    and "two","2222222"...
    please tell me how can i do that?

      Something like this would do the trick:
      @

      void Dialog::AddChild(QTreeWidgetItem *parent,QString name, QString Description)
      {
      QTreeWidgetItem *itm =new QTreeWidgetItem();
      itm->setText(0,name);
      itm->setText(1,Description);
      itm->setFlags(itm->flags() | Qt::ItemIsUserCheckable);
      itm->setCheckState(Qt::Checked);
      parent->addChild(itm);
      }
      @

      It first sets the item to be checkable, and then sets the current checked state to checked.
