gtk:tree-selection-selected-foreach (selection func)

selection -- a gtk:tree-selection object
func -- a gtk:tree-selection-foreach-func callback function to call for each selected node

Calls a function for each selected node. Note that you cannot modify the tree view or selection from within this function. As a result, the gtk:tree-selection-selected-rows function might be more useful. The gtk:tree-selection implementation is deprecated since 4.10. Please do not use it in newly written code.
