A widget which displays a list of icons in a grid

provides an alternative view on a list model. It displays the model as a grid of icons with labels. Like , it allows to select one or multiple items (depending on the selection mode, see ). In addition to selection with the arrow keys, supports rubberband selection, which is controlled by dragging the pointer.
