Is there a way to create a list, array or dyn_... of ctrl++ objects? Or can I implement a generic list?

With kind regards

There is an easy way to create a list of objects with dyn_anytype. After troubleshooting I found the bug of my problem.
The order of the classes in the same script is critical!

Dosn't working MWE:

Code: Select all

class MyObject1
{
  private string sName;
  private dyn_anytype daObjects;

  public MyObject1( string sName = "" )
  {
    this.sName = sName;
  }

  public void append( MyObject2 pObject )
  {
    dynAppend( daObjects, pObject );
  }

  public MyObject2 getObject( int pNumb )
  {
    return daObjects[pNumb];
  }
};

class MyObject2
{
  private string sName;

  public MyObject( string sName = "" )
  {
    this.sName = sName;
  }
};

If I change the order of classes then can I use classes as parameter and return value in functions. Another solution exists with separate scripts for each class.

MWE:

Code: Select all

class MyObject2
{
  private string sName;

  public MyObject( string sName = "" )
  {
    this.sName = sName;
  }
};

class MyObject1
{
  private string sName;
  private dyn_anytype daObjects;

  public MyObject1( string sName = "" )
  {
    this.sName = sName;
  }

  public void append( MyObject2 pObject )
  {
    dynAppend( daObjects, pObject );
  }

  public MyObject2 getObject( int pNumb )
  {
    return daObjects[pNumb];
  }
};

Is there a possibility of forward declaration in ctrl ++?
