    Default how to add check box inside qtree widget?

    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
    Qt Code:
    1. #include "dialog.h"
    2. #include "ui_dialog.h"
    3. #include <QtCore>
    4. #include <QtGui>
    5.  
    6. Dialog::Dialog(QWidget *parent) :
    7. QDialog(parent),
    8. ui(new Ui::Dialog)
    9. {
    10.  
    11. ui->setupUi(this);
    12.  
    13. ui->treeWidget->setColumnCount(2);
    14. ui->treeWidget->setHeaderLabels(QStringList()<< "one"<<"two");
    15. AddRoot("1 first","tree");
    16. AddRoot("2 second","person");
    17. AddRoot("3 third","man");
    18. AddRoot("4 fourth","and last");
    19.  
    20. }
    21.  
    22. Dialog::~Dialog()
    23. {
    24. delete ui;
    25. }
    26. void Dialog::AddRoot(QString name,QString Description)
    27. {
    28. QTreeWidgetItem *itm =new QTreeWidgetItem(ui->treeWidget);
    29. itm->setText(0,name);
    30. itm->setText(1,Description);
    31.  
    32.  
    33. AddChild(itm,"one","1111");
    34. AddChild(itm,"two","2222");
    35. }
    36.  
    37. void Dialog::AddChild(QTreeWidgetItem *parent,QString name, QString Description)
    38. {
    39. itm->setText(0,name);
    40. itm->setText(1,Description);
    41. parent->addChild(itm);
    42. }
    43.  
    44. void Dialog::on_pushButton_clicked()
    45. {
    46. ui->treeWidget->currentItem()->setBackgroundColor(0,Qt::red);
    47.  
    48. ui->treeWidget->currentItem()->setBackgroundColor(1,Qt::blue);
    49. }

    Hello.
    In QTableWidget I used
    setFlags ( Qt::ItemFlags flags )
    and add flags Qt::ItemIsUserCheckable.
    Try in your case.
    The QTreeWidget has the same features.

    You already have the name of the function, QTreeWidgetItem::setFlags(), its documentation, and the Qt::ItemFlag documentation it links to. You even have the the name of the specific flag, Qt::ItemIsUserCheckable. Is it really such a difficult thing to work out?
    Qt Code:
    1. // OR QTableWidgetItem *item = new QTableWidgetItem();
    2. // OR QStandardItem *item = new QStandardItem();
    3. item->setFlags(Qt::ItemIsEnabled | Qt::ItemIsEditable | Qt::ItemIsUserCheckable);
