It does not make sense to render every cell in a treeview as drop target, even when the treeview itself is set as a drop destination. https://bugzilla.gnome.org/show_bug.cgi?id=761686

* SECTION:gtkcellrenderer
|
||
* @Short_description: An object for rendering a single cell
|
||
* @Title: GtkCellRenderer
|
||
* @See_also: #GtkCellRendererText, #GtkCellRendererPixbuf, #GtkCellRendererToggle
|
||
*
|
||
* The #GtkCellRenderer is a base class of a set of objects used for
|
||
* rendering a cell to a #cairo_t. These objects are used primarily by
|
||
* the #GtkTreeView widget, though they aren’t tied to them in any
|
||
* specific way. It is worth noting that #GtkCellRenderer is not a
|
||
* #GtkWidget and cannot be treated as such.
|
||
*
|
||
* The primary use of a #GtkCellRenderer is for drawing a certain graphical
|
||
* elements on a #cairo_t. Typically, one cell renderer is used to
|
||
* draw many cells on the screen. To this extent, it isn’t expected that a
|
||
* CellRenderer keep any permanent state around. Instead, any state is set
|
||
* just prior to use using #GObjects property system. Then, the
|
||
* cell is measured using gtk_cell_renderer_get_size(). Finally, the cell
|
||
* is rendered in the correct location using gtk_cell_renderer_render().
|
||
*
|
||
* There are a number of rules that must be followed when writing a new
|
||
* #GtkCellRenderer. First and foremost, it’s important that a certain set
|
||
* of properties will always yield a cell renderer of the same size,
|
||
* barring a #GtkStyle change. The #GtkCellRenderer also has a number of
|
||
* generic properties that are expected to be honored by all children.
|
||
*
|
||
* Beyond merely rendering a cell, cell renderers can optionally
|
||
* provide active user interface elements. A cell renderer can be
|
||
* “activatable” like #GtkCellRendererToggle,
|
||
* which toggles when it gets activated by a mouse click, or it can be
|
||
* “editable” like #GtkCellRendererText, which
|
||
* allows the user to edit the text using a #GtkEntry.
|
||
* To make a cell renderer activatable or editable, you have to
|
||
* implement the #GtkCellRendererClass.activate or
|
||
* #GtkCellRendererClass.start_editing virtual functions, respectively.
|
||
*
|
||
* Many properties of #GtkCellRenderer and its subclasses have a
|
||
* corresponding “set” property, e.g. “cell-background-set” corresponds
|
||
* to “cell-background”. These “set” properties reflect whether a property
|
||
* has been set or not. You should not set them independently.
