Component arrays?

The Projucer
1

I’m using about 60 sliders in my new synth and each slider corresponds to a parameter. In roid, I kept the sliders in an array with the indices corresponding to the synth parameter index. This made updating back and forth very easy.

Can Jucer make arrays somehow?

Hmm - that’d be a bit complex to get it to do, and I can’t even think how you’d attempt to put it into the UI!

Ok. I’ll just have to settle for a GUI and make the transition manually. It will keep me from doing uneeded tweaks. :smiley:

I’d think that you could implement it as a sort of meta object though. You create an Component array, and then the type of component as well as the number are it’s properties. You could even add a list that creates an enum.

This just puts the widgets on the screen and from then on its all still manual.

My code ends up looking like this:

     //Sliders, Common props
     for(int i = 0; i < 41; i++){
         addAndMakeVisible (Sliders[i] = new SnappingSlider (T("DobbiDoo")));
         Sliders[i]->setRange (0, 1.0f, 0);
         Sliders[i]->setSliderStyle (Slider::RotaryVerticalDrag);
         Sliders[i]->setTextBoxStyle (Slider::NoTextBox, true, 80, 20);
         Sliders[i]->addListener (this);
         Sliders[i]->setSnap(0.0f , 0.05f);
     }

    //Sliders, Specials
    Sliders[penv_amt]->setRange (-1, 1, 0);
    Sliders[fenv_amt]->setRange (-1, 1, 0);
    Sliders[f_80]->setRange (-1, 1, 0);
    Sliders[vel_filter]->setRange (-1, 1, 0);
    Sliders[vel_pitch]->setRange (-1, 1, 0);
    Sliders[o1_semi]->setRange (-1, 1, 0);
    Sliders[o2_semi]->setRange (-1, 1, 0);
    Sliders[o1_cent]->setRange (-1, 1, 0);
    Sliders[o2_cent]->setRange (-1, 1, 0);
    Sliders[o_mix]->setRange (-1, 1, 0);
    Sliders[g_len]->setRange (0, 32, 1);
    Sliders[vel_amp]->setRange (-1, 1, 0);

    Sliders[penv_a]->setBounds (428, 28, 32, 32);
    Sliders[penv_d]->setBounds (460, 28, 32, 32);
    Sliders[penv_s]->setBounds (492, 28, 32, 32);
    Sliders[penv_r]->setBounds (524, 28, 32, 32);
    Sliders[penv_amt]->setBounds (556, 12, 32, 32);
    Sliders[fenv_a]->setBounds (428, 104, 32, 32);
    Sliders[fenv_s]->setBounds (460, 104, 32, 32);
    Sliders[fenv_d]->setBounds (492, 104, 32, 32);
    Sliders[fenv_r]->setBounds (524, 104, 32, 32);
    Sliders[fenv_amt]->setBounds (556, 88, 32, 32);
    Sliders[aenv_a]->setBounds (428, 180, 32, 32);
    Sliders[aenv_d]->setBounds (460, 180, 32, 32);
    Sliders[aenv_s]->setBounds (492, 180, 32, 32);
    Sliders[aenv_r]->setBounds (524, 180, 32, 32);

I don’t mind doing it manually though.

You could always create an array, and in the constructor, copy all the jucer’s components into the appropriate index, then use the array instead of the normal pointers?

Yeah. That ought to work. That way I only have to do the mapping once and can still just plug in the Jucer code.

Good call.
