How to show two icon in QTreeView

Hello

I am developing an application using Christophe Dumez's blog cdumez http://blogspot.in/2010/11/how-to-us...del-in-qml.htm
Then i am showing my items using QTreeView.
In tree model it take only one icon.

Now i want to show two icons (One on left side of text & other on right side of text) in same row.
so how can i do that.
Can any one suggest me(any example) for that

Maybe could you provide a piece of your code?

My model is custom, which is an abstract model. I have learned about Item delegate & try to find example code to display tow icons in a row but not successful. I found example about custom delegate e.g star delegate(http://qt-project.org/doc/qt-4.8/ite...rdelegate.html) but nothing for TreeView. I want to only display two icons in a row which display when my treeview display. But still i don't have any idea how to do that, so thats why i can't provide any code?

QTreeView uses the same delegates as other view classes. You can use exactly the same approach. I have no idea what it has to do with the QML-related block post you linked to in your opening post.

Hi,
i am using QItemDelegates paint method for custom delegate. My code is as following
.h file

Code:

---

#include <QItemDelegate>
#include <QModelIndex>
#include <QObject>
#include <QSize>
#include <QSpinBox>
 
class TreeViewItemDelegate : public QItemDelegate
{
    Q_OBJECT
 
public:
    TreeViewItemDelegate(QObject *parent = 0);
 
    void paint( QPainter * painter,
                const QStyleOptionViewItem & option,
                const QModelIndex & index ) const;
};

---

.cpp file

Code:

---

TreeViewItemDelegate::TreeViewItemDelegate(QObject *parent)
    : QItemDelegate(parent)
{
}
 
void TreeViewItemDelegate ::paint( QPainter * painter,
            const QStyleOptionViewItem & option,
            const QModelIndex & index ) const
{
    QString contactURI = index.model()->data(index, Qt::DisplayRole).toString();
    QIcon icon =  qvariant_cast<QIcon>(index.model()->data(index, Qt::DecorationRole));
    QIcon icon2 =  qvariant_cast<QIcon>(index.model()->data(index, Qt::UserRole+5));
 
    QPixmap iconPixmap = icon.pixmap(option.decorationSize);
    QPixmap iconPixmap2 = icon2.pixmap(option.decorationSize);
 
    QStyleOptionViewItem myoption = option;
    QStyleOptionViewItem myoption2 = option;
    QStyleOptionViewItem myoption3 = option;
    myoption.displayAlignment = Qt::AlignCenter;
    myoption2.decorationAlignment = Qt::AlignLeft;
    myoption3.decorationAlignment = Qt::AlignRight;
 
    drawBackground(painter, myoption, index);
    drawDecoration(painter, myoption, myoption2.rect, iconPixmap);
    drawDisplay(painter,myoption, myoption.rect, contactURI);
    drawDecoration(painter, myoption, myoption3.rect, iconPixmap2);
    drawFocus(painter, myoption,myoption.rect);
}

---

There is on problem that only one icon is displaying. I know i am doing something wrong, so can anyone help me to correct this code to display both icon??

Don't call drawDecoration() for the additional icon. Instead use QPainter::drawPixmap() directly.

i added two more lines in my cpp file

Code:

---

QRect *rect = new QRect(0,0,10,10);
painter->drawPixmap(rect,iconPixmap);

---

but it is not working..

It doesn't even compile. And if it did, the rect probably doesn't make sense anyway.
