bool Gtk::TreeDragDest::drag_data_received | ( | const TreeModel::Path & | dest, |
const Glib::ValueBase & | value | ||
) |
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!
dest | Row to drop in front of. |
value | Data to drop. |

bool Gtk::TreeDragDest::row_drop_possible | ( | const TreeModel::Path & | dest_path, |
const Glib::ValueBase & | value | ||
) | const |
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.
dest_path | Destination row. |
value | The data being dropped. |
true
if a drop is possible before dest_path.
