[Qt-interest] Fwd: signal and slot in QTreeView

[ami guru]

Hello Arnold

thanks for the hint.

Could not make much out of it though.

I want to show the property value in the Mesage Box when  the user click any
of the tree item.

As Qt tells you, there is no clicked() signal in QTreeView or any of its
inherited classes. And what would you know from that signal? Only that the
user clicked somewhere in the widget? How useless.
You are probably searching for QAbstractItemView::clicked( const
QModelIndex&
) or for QAbstractItemView::activated( const QModelIndex& )... These two
have
the advantage that they already give you the item that was clicked on, so
you
don't have to determine that yourself.

Have fun,

Arnold
