tree_get_row_drag_data


Description:

public bool tree_get_row_drag_data (SelectionData selection_data, out TreeModel? tree_model, out TreePath? path)

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 TreeDragDest 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 free.

Parameters:

selection_data

a SelectionData

tree_model

a TreeModel

path

row in tree_model

Returns:

true if selection_data had target type gtk_tree_model_row and is otherwise valid
