Hello,  
I’m very new to all of this so I am sorry if this is completely obvious but still, I miss it.

I want to create a vector of sliders in order to make a simple step sequencer. However, this line of code generates an error :

```
midiVolStep.push_back(initSlider);

```

I get the error :

```
Error	C2248: 'juce::Slider::Slider' : impossible to access a private member declared int the class 'juce::Slider' (compilation of source file ..\..\Source\PluginEditor.cpp)	

```

I’m compiling with VS Community 2017

Thank you (and sorry if this question is stupid) 🙂

`OwnedArray` would be a better option for holding multiple sliders:

```auto
OwnedArray<Slider> mySliders;
mySliders.add(new Slider());
addAndMakeVisible(mySliders.getLast());

```

N.B. that [OwnedArray::add()](https://docs.juce.com/develop/classOwnedArray.html#a71587e33a86ec14556128e162470319f) returns the added element as pointer, so you don’t need the ugly .getLast() like you have to do in std::vector:

```auto
OwnedArray<Slider> mySliders;

auto* slider = mySliders.add(new Slider());
addAndMakeVisible (slider);

```

or even:

```auto
OwnedArray<Slider> mySliders;

addAndMakeVisible (mySliders.add (new Slider()));

```
