using QListWidget and checkboxs ?

[tamnv110]

Hello everybody!
I want to create a QString listwidget and which contains a checkbox and qstring on the same row. But I can not pass in the second with a time listwidget be, so I used 2 listwidget to save QString and checkbox. So my interface looks very bad, I want my interface like in the picture below. How do I do?

Instead of QListWidget use a QTreeWidget with two columns.
Then use QTreeWidget::setItemWidget() to insert a Check Box

item = new QTreeWidgetItem (ui->treeWidget);
item->setText (0, yourText);
ui->treeWidget->setItemWidget (item, 1, new QCheckBox);

item = new QTreeWidgetItem (ui->treeWidget);
item->setText (0, yourText);
ui->treeWidget->setItemWidget (item, 1, new QCheckBox);

you can subclass QStyledItemDelegate and in re implement paintEvent as

void styledListItemDelegate::paint(QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index) const
{
 
    QStyleOptionViewItem myOpt = option;
    initStyleOption(&myOpt,index);
    //for drawing the checkbox
    QStyleOptionButton opt;
 
 
    QRect chkRect(option.rect.right() - option.rect.height(),
                  option.rect.top(),
                  option.rect.height(),
                  option.rect.height());
    opt.rect = chkRect;
 
    if(option.state & QStyle::State_Selected)
        opt.state = QStyle::State_On;
 
    QApplication::style()->drawControl(QStyle::CE_CheckBox,
                                       &opt, painter);
 
    //adjust the rect for displayed text 
    int dw = -chkRect.width();
    myOpt.rect.adjust(0,0,dw,0);
    QStyledItemDelegate::paint(painter, myOpt, index);
}

void styledListItemDelegate::paint(QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index) const
{

    QStyleOptionViewItem myOpt = option;
    initStyleOption(&myOpt,index);
    //for drawing the checkbox
    QStyleOptionButton opt;


    QRect chkRect(option.rect.right() - option.rect.height(),
                  option.rect.top(),
                  option.rect.height(),
                  option.rect.height());
    opt.rect = chkRect;

    if(option.state & QStyle::State_Selected)
        opt.state = QStyle::State_On;

    QApplication::style()->drawControl(QStyle::CE_CheckBox,
                                       &opt, painter);

    //adjust the rect for displayed text 
    int dw = -chkRect.width();
    myOpt.rect.adjust(0,0,dw,0);
    QStyledItemDelegate::paint(painter, myOpt, index);
}

To copy to clipboard, switch view to plain text mode 

set the item delegate for the list widget in your code

listWidget = new QListWidget();
 
    listWidget->setItemDelegate(new styledListItemDelegate());
 
    new QListWidgetItem(tr("Oak"), listWidget);
 
    new QListWidgetItem(tr("Fir"), listWidget);
 
    new QListWidgetItem(tr("Pine"), listWidget);

listWidget = new QListWidget();

    listWidget->setItemDelegate(new styledListItemDelegate());
    
    new QListWidgetItem(tr("Oak"), listWidget);

    new QListWidgetItem(tr("Fir"), listWidget);

    new QListWidgetItem(tr("Pine"), listWidget);

To copy to clipboard, switch view to plain text mode 

Please note that I have shown code for enabling checkboxes on the left side of the text you need to write code to handle stuff like switching on and off the checked state etc.

Hope this helps

Thank mcosta, Sukesh ! I have done.

The Widget what you want looks for me like a QTableWidget and neither like a QListWidget or QTreeWidget.
Maybe you can use QCheckBox with "openPersistentEditor" ?
