Is it possible?

Is it possible to create dynamically allocated tables of objects (classes or structs or something like this)?

The code:

...
Type MyClass = Class
  public
    Arr : Array of String;
end;
...
var Arr2 : array of MyClass;
...
SetLength(Arr2,10);                  
SetLength(Arr2[1].Arr,10);
Arr2[1].Arr[1]:='Hello World!';  // here I got error: sigsegv raised
...

What did I do wrong?

... allocated tables of objects...

I meant "arrays of objects".

Any obejct you want to use, you need to create first. This can be done dynamically of course.
So if you did something like this:

Code: [Select]


var Arr2: array of MyClass;
...
  SetLength(Arr2, 10);
  for I := 0 to 9 do
    Arr2[I] := MyClass.Create;
  SetLength(Arr2[0].Arr, 10);
  Arr2[0].Arr[0] := 'Hello world';
  ...

It might work.
