Function

Gtktree_get_row_drag_data

Declaration [src]

gboolean
gtk_tree_get_row_drag_data (
  GtkSelectionData* selection_data,
  GtkTreeModel** tree_model,
  GtkTreePath** path
)

Description [src]

Obtains a tree_model and path from selection data of target type GTK_TREE_MODEL_ROW. Normally called from a drag_data_received handler. This function can only be used if selection_data originates from the same process that’s calling this function, because a pointer to the tree model is being passed around. If you aren’t in the same process, then you’ll get memory corruption. In the GtkTreeDragDest drag_data_received handler, you can assume that selection data of type GTK_TREE_MODEL_ROW is in from the current process. The returned path must be freed with gtk_tree_path_free().

Parameters

`selection_data`	`GtkSelectionData`
	A `GtkSelectionData`.
	The data is owned by the caller of the function.
`tree_model`	`GtkTreeModel`
	A `GtkTreeModel`.
	The argument will be set by the function.
	The argument can be set to `NULL`.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`path`	`GtkTreePath`
	Row in `tree_model`.
	The argument will be set by the function.
	The argument can be set to `NULL`.
	The argument can be `NULL`.
	The called function takes ownership of the data, and is responsible for freeing it.

Return value

Returns:	`gboolean`
	`TRUE` if `selection_data` had target type `GTK_TREE_MODEL_ROW` and is otherwise valid.
