Interface for Drag-and-Drop destinations in Gtk::TreeView.
- Deprecated:
- 4.10: List views use widgets to display their contents. You can use Gtk::DropTarget to implement a drop destination.

◆ drag_data_received()
Asks the Gtk::TreeDragDest
to insert a row before the path dest, deriving the contents of the row from value.
If dest is outside the tree so that inserting before it is impossible, false
will be returned. Also, false
may be returned if the new row is not created for some model-specific reason. Should robustly handle a dest no longer found in the model!
Deprecated: 4.10: Use list models instead
- Parameters
-
dest | Row to drop in front of. |
value | Data to drop. |
- Returns
- Whether a new row was created before position dest.
◆ drag_data_received_vfunc()

Get the GType for this class, for use with the underlying GObject type system.
◆ gobj() [1/2]
Provides access to the underlying C GObject.
◆ gobj() [2/2]
Provides access to the underlying C GObject.
◆ operator=()
◆ row_drop_possible()
Determines whether a drop is possible before the given dest_path, at the same depth as dest_path.
i.e., can we drop the data in value at that location. dest_path does not have to exist; the return value will almost certainly be false
if the parent of dest_path doesn’t exist, though.
Deprecated: 4.10: Use list models instead
- Parameters
-
dest_path | Destination row. |
value | The data being dropped. |
- Returns
true
if a drop is possible before dest_path.
◆ row_drop_possible_vfunc()
◆ wrap()
A Glib::wrap() method for this object.
- Parameters
-
object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
- Returns
- A C++ instance that wraps this C instance.
