In particular, rename - libraries to lib*-3.0.so - pc files to *-3.0.pc - include paths to /usr/include/gtk-3.0/* - module paths to /usr/lib/gtk-3.0/* - rc files names to gtk-3.0/gtkrc - commandline utilities to *-3.0 - adjust documentation Also change the install location for unix-print headers to /usr/include/gtk-3.0/unix-print/gtk.

|
GTK+ supports Drag-and-Drop in tree views with a high-level and a low-level
|
|
API.
|
|
</para>
|
|
<para>
|
|
The low-level API consists of the GTK+ DND API, augmented by some treeview
|
|
utility functions: gtk_tree_view_set_drag_dest_row(),
|
|
gtk_tree_view_get_drag_dest_row(), gtk_tree_view_get_dest_row_at_pos(),
|
|
gtk_tree_view_create_row_drag_icon(), gtk_tree_set_row_drag_data() and
|
|
gtk_tree_get_row_drag_data(). This API leaves a lot of flexibility, but
|
|
nothing is done automatically, and implementing advanced features like
|
|
hover-to-open-rows or autoscrolling on top of this API is a lot of work.
|
|
</para>
|
|
<para>
|
|
On the other hand, if you write to the high-level API, then all the
|
|
bookkeeping of rows is done for you, as well as things like hover-to-open
|
|
and auto-scroll, but your models have to implement the
|
|
#GtkTreeDragSource and #GtkTreeDragDest interfaces.
