I've decided that it is isn't feasible to make cell areas runtime-settable in the time we have left before 3.0, therefore, I'm going with the approach to allow init() functions to instantiate the default cell area and issue a warning if a construct property is ignored. This is not ideal, but it keeps existing icon view and combo box subclasses working. https://bugzilla.gnome.org/show_bug.cgi?id=639139

/**

* SECTION:gtkiconview
|
|
* @title: GtkIconView
|
|
* @short_description: A widget which displays a list of icons in a grid
|
|
*
|
|
* #GtkIconView provides an alternative view on a #GtkTreeModel.
|
|
* It displays the model as a grid of icons with labels. Like
|
|
* #GtkTreeView, it allows to select one or multiple items
|
|
* (depending on the selection mode, see gtk_icon_view_set_selection_mode()).
|
|
* In addition to selection with the arrow keys, #GtkIconView supports
|
|
* rubberband selection, which is controlled by dragging the pointer.
|
|
*
|
|
* Note that if the tree model is backed by an actual tree store (as
|
|
* opposed to a flat list where the mapping to icons is obvious),
|
|
* #GtkIconView will only display the first level of the tree and
|
|
* ignore the tree's branches.

* drop can not be used in a reorderable view for any other purpose.
