/*!
* \brief
* Returns the string representation of the specified ModelIndex based on
* the specified role.
* It is up to the view to interpret the string based on the role requested.
*
* \remark
* For example, in the case of an image decoration, the name of the image
* could be returned, and the view would use ImageManager to retrieve the
* specific Image instance by the name and render that.
*
* An example implementation for the IDR_Icon role could be:
* \code{.cpp}
* Image* img; // get the image from somewhere
*
* String getData(const ModelIndex& modelIndex, ItemDataRole role)
* {
* if (role == IDR_Icon) return img->getName();
* }
* \endcode
