It seems pure qml projects don't really work in our examples architecture at the moment. This change adds a simple main file and resource bundle to each of the example folders. Change-Id: I4758242e71a2cb053252cbb09bf5c4439415691d Reviewed-by:Jens Bache-Wiig <jens.bache-wiig@digia.com>

As with \l ListView, data for each row is provided through a \l model: \code ListModel { id: libraryModel ListElement{ title: "A Masterpiece" ; author: "Gabriel" } ListElement{ title: "Brilliance" ; author: "Jens" } ListElement{ title: "Outstanding" ; author: "Frederik" } } \endcode You provide title and size of a column header by adding a \l TableViewColumn to the default \l header property as demonstrated below. \code7172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120121122123124125126127128129130131132133134135136137138139140
TableView {
TableViewColumn{ role: "title" ; title: "Title" ; width: 100 }
TableViewColumn{ role: "author" ; title: "Author" ; width: 200 }
model: libraryModel
}
\endcode
The header sections are attached to values in the \l model by defining
the model role they attach to. Each property in the model will
then be shown in their corresponding column.
You can customize the look by overriding the \l itemDelegate,
\l rowDelegate, or \l headerDelegate properties.
The view itself does not provide sorting. This has to
be done on the model itself. However you can provide sorting
on the model, and enable sort indicators on headers.
\list
\li int sortIndicatorColumn - The index of the current sort column
\li bool sortIndicatorVisible - Whether the sort indicator should be enabled
\li enum sortIndicatorOrder - Qt.AscendingOrder or Qt.DescendingOrder depending on state

This property holds the model providing data for the table view.
The model provides the set of data that is used to create the items in the view.
Models can be created directly in QML using ListModel, XmlListModel or VisualItemModel,
or provided by C++ model classes. \sa ListView::model
Example model:
\code

ListElement{ column1: "value 1" ; column2: "value 2" }
ListElement{ column1: "value 3" ; column2: "value 4" }
}

\qmlmethod TableView::positionViewAtRow( int row, PositionMode mode )
Positions the view such that the specified \a row is at the position defined by \a mode:
\list
\li ListView.Beginning - position item at the top of the view.
\li ListView.Center - position item in the center of the view.
\li ListView.End - position item at bottom of the view.
\li ListView.Visible - if any part of the item is visible then take no action, otherwise bring the item into view.
\li ListView.Contain - ensure the entire item is visible. If the item is larger than the view the item is positioned
at the top of the view.
\endlist
If positioning the \a row creates an empty space at the beginning
or end of the view, then the view is positioned at the boundary.
For example, to position the view at the end at startup:
\code
Component.onCompleted: table.positionViewAtRow(rowCount -1, ListView.Contain)
\endcode
Depending on how the model is populated, the model may not be ready when
TableView Component.onCompleted is called. In that case you may need to
delay the call to positionViewAtRow by using a \l {Timer}.
\note This method should only be called after the component has completed.
