Member Function Documentation

static void Gtk::TreeDragDest::add_interface ( GType gtype_implementer )
static
bool Gtk::TreeDragDest::drag_data_received ( const TreeModel::Path & dest ,
const SelectionData & selection_data
)

Asks the Gtk::TreeDragDest to insert a row before the path dest , deriving the contents of the row from selection_data .

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!

Parameters
dest Row to drop in front of.
selection_data Data to drop.
Returns
Whether a new row was created before position dest .

GtkTreeDragDest* Gtk::TreeDragDest::gobj ( )

const GtkTreeDragDest* Gtk::TreeDragDest::gobj ( ) const
inline

Provides access to the underlying C GObject.

TreeDragDest & Gtk::TreeDragDest::operator= ( TreeDragDest && src )
noexcept
bool Gtk::TreeDragDest::row_drop_possible ( const TreeModel::Path & dest_path ,
const SelectionData & selection_data
) 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 selection_data 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.

Parameters
dest_path Destination row.
selection_data The data being dragged.
Returns
true if a drop is possible before dest_path .
virtual bool Gtk::TreeDragDest::row_drop_possible_vfunc ( const TreeModel::Path & dest ,
const SelectionData & selection_data

Friends And Related Function Documentation

Glib::RefPtr < Gtk::TreeDragDest > wrap ( GtkTreeDragDest * object ,
bool take_copy = false
)
related

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.
