KDevelop shows me a tooltip that includes the type of the variable (here: DoFHandler<dim>active_cell_iterator
), where this variable is declared (the container, which here is the surrounding function get_maximal_velocity
since it is a local variable), what it is (a variable, not a function, class or namespace) and where it is declared (in line 1314, just a few lines up in the code).
