Hello, I'm trying to store a custom class that I made (called Circle), which inherits from Component, into a vector so I can draw a collection of circles all over the screen and erase them. I want to add the with push\_back() and erase with pop\_back. I'm only overriding the paint() method. I'm getting a compile every when I try to use push\_back though and I can't seem to figure out how to do it. Here's the error: Error    2    error C2248: 'juce::Component::Component' : cannot access private member declared in class 'juce::Component' (..\..\Source\MainComponent.cpp)    Here's the class:   ``` class Circle : public Component { public: Circle(const float x, const float y, const float radius, const Colour colour); void paint (Graphics&); private: float m_x; float m_y; float m_radius; Colour m_colour; float m_diameter; }; Circle::Circle(const float x, const float y, const float radius, const Colour colour) :m_x{ x }, m_y{ y }, m_radius{ radius }, m_colour{ colour } { m_diameter = m_radius * 2; } void Circle::paint(Graphics& g) { g.setColour(m_colour); g.fillEllipse(m_x, m_y, m_diameter, m_diameter); } ```   And I'm just trying to use it something like this: ``` vector circles; ``` ``` circles.push_back(Circle{ x, y, 10.0f, red }); ```   I'm sure there's a much better way of doing this, but I'm new to JUCE and this is similar to the way I did it in Cinder. If anyone knows how to fix this, or even a better way of doing this I would be really grateful. Idk why I can't get this to work. I don't know if I should even be inheriting from Component.     ---

Actually, I just didn't inheret from anything and I got it working. I guess that'll work for what I'm wanting to do. :) ---

I'm still curious if you can create and store components in an array though. I'd like to create an array of circles then somehow move those circles around by clicking + dragging them.  ---

Well.... just try this to call the constructor instead of loading directly the private members, it should work better :-) ``` circles.push_back(Circle ( x, y, 10.0f, red ) ); ``` But anyway you should consider using Juce's Array or OwnedArray instead of stdlib members. Take time having a look at the complete Juce object model, you'll find a lot of useful things that will simplify your life ;-)   /Phil ---

Thanks for replying man. I'll have to check out JUCE's arrays and other data structures. This is just practice anyways. I'm trying to learn as much about JUCE as I can and I thought this would be a good exercise.  ---

What do you know, Getting Started With JUCE has 2 sections on storing components in the JUCE Array and OwnedArray classes. Man, I feel dumb for not noticing that. Now I should be able to figure that out. :) That's in chapter 3 if anyone else needs this. ---

Component is NOT copyable (and AFAIK not movable)? ---

No - how could it be copyable!? If you copy it, what would happen to its child components or parent component? What about all the listeners that are attached? etc etc! ---

Hey Jules, it was not a question. It was just a suggestion to the OP why using a vector of Components is not a good idea. Of course it can not be copied 😉 ---

Sure :) I was just confirming why that's the case, for anyone who might have been reading and not seeing why that is. ---

i had a feeling that's what it was. Thanks for replying everyone. I'm still figuring out how components work. I love how helpful this forum is. Sorry for all the noob questions. I try to only ask if I can't find the answer.
