<![CDATA[how to have double click on a image on single click]]>I display a QPixMap in QTreevIew . When the user double clicks on the image I should bring QColorDialog

I tried following code but I can get the behavior on single click but I want the behavior only on double click

MyInstView::myInstView(QWidget* dparent)
: QTreeView(dparent),
{
connect(this, SIGNAL(clicked(const QModelIndex&)),
this, SLOT(clickInstance(const QModelIndex&)));
}

If you are using Qt 5, then you should go for the new syntax. That would have already failed at compile time.

Object::connect: No such signal GQInstView::doubleclicked(QModelIndex)

the code is as follows -----
GQInstView::GQInstView(QWidget* dparent)
: QTreeView(dparent), model(0),
{
QObject::connect(this, SIGNAL(doubleclicked(const QModelIndex&)), this, SLOT(clickInstance(const QModelIndex&)));
}

Is there anything I am missing

Why not use the doubleClicked signal ?
