Why this NED file don t have design tab?

Question

I am trying to modify one simulation and I find this ned file that don t have design tab ("Design mode"). Name of the file is simulation.ned. Inside this file it s define package, Simulation is define as "simple" module and inside parameters part there are just simulation global parameters.

simple Simulator
{
        parameters:

        double LogPeriod= default (3600.0);
        double updatePeriodPN= default (7200.0);
        bool DateTime=default(false); 
        int debugLevel=default(0);
        xml configFileName;

        gates:
        inout directInGate @directIn;
}

My question is why this ned file don t have design tab (Design mode)? Is this some kind of special ned file that is present in every simulation (tictoc examples don t have this type of ned file). Other ned files although with a same structure they have design tab (graphical environment)

Answer 1

This is not about the file but rather where the file is. You must configure the ned folders in your project settings and only NED files inside the ned folders are shown as dual mode editors. Anything outside the ned folders are shown just as a basic text editor.
