Vector of Button [message #49509]

Hi there,
I am trying to create an interface that has a list of Button, each for every user in a list: each Button has the name of the user on the Label.

What I have done so far:

Vector<Button> vbo;

...

	vbo.Clear();
	for (size_t i=0; i<userslist.size(); i++) {
		Button b;
		vbo.Add(b);
	}

	for (size_t i=0; i<userslist.size(); i++) {
			vbo[i].SetLabel(userslist[i].FULLNAME);
			Add(vbo[i].VCenterPos(500-i*40).HCenterPos(300) );
	}

But when compiling I get the following errors:
-Error C2280: attempting to reference a deleted function
-Error C2100: illegal indirection

Is it possible to have a Vector of Button? And if it is, how can I declare and use it?
Thanks,
Gio

Hello Giorgio,

AFAIK you can't create a vector of buttons, since it is not moveable (not directly at least).
You can use Array instead. Their interfaces are almost identical.

Array<Button> vbo; <----

...

	vbo.Clear();
	for (size_t i=0; i<userslist.size(); i++) {
		auto& bt= vbo.Add()                    
                bt.SetLabel(userslist[i].FULLNAME);
	        Add(bt.VCenterPos(500-i*40).HCenterPos(300) );
	}

If you insist on using vector, you can use One<Button>: (See One<> in U++ docs.)
