I'm trying to hide/unhide gizmos in a GeDialog. But once they are hidden I can't manage to bring them back again.

Here's my button code that calls the hide/unhide for a gizmo
Hide works fine. But the unhide code does not work:

    switch (id)   
  {  
      case MY_BUTTON_HIDE:  
          HideElement(MY_GIZMO, TRUE);       //Tell C4D to hide this gizmo  
          LayoutFlushGroup(GIMO_GROUP_ID);   //Redraw the gizmo's group reflecting the changes  
          LayoutChanged(GIMO_GROUP_ID);      //Tell C4D the GeDialog has changed  
          break;  
  
      case MY_BUTTON_UNHIDE:  
          HideElement(MY_GIZMO, FALSE);  
          LayoutFlushGroup(GIMO_GROUP_ID);  //<--This code block does not bring the gizmo back!?  
          LayoutChanged(GIMO_GROUP_ID);  
          break;  
  }

Do I need to use a gadget *ptr for this?
The docs show an example how to create a gadget ptr

C4DGadget* ptr = dlg.AddStaticText(123, ...); // Generates GadgetPtr(123)

Which I'm assuming is placed inside the CreateLayout() method?
But then I'm unclear how to actually use this new ptr.

Normally I would create a ptr like this as a class member variable so it's available for use in all the methods in my plugin. But the way it's written in the docs it appears to be created as a local CreateLayout() variable.
So I don't know how to actually use that ptr in my Command() method where my buttons code is?

Doh!
Nevermind. I found what I was doing wrong.

By using LayoutFlushGroup() when hiding the gizmo. I am basically deleting the gizmo from the dialog. So it has no way of returning back to where I started from when I choose to unhide it.

So the code needs to be like this:

    switch (id)   
  {  
      case MY_BUTTON_HIDE:  
          HideElement(MY_GIZMO, TRUE);       //Tell C4D to hide this gizmo    
          LayoutChanged(GIZMO_GROUP_ID);     //Tell C4D the group this gizmo is in has changed  
          break;  
  
      case MY_BUTTON_UNHIDE:  
          HideElement(MY_GIZMO, FALSE);     //Tell C4D to unhide this gizmo    
          LayoutChanged(GIZMO_GROUP_ID);    //Tell C4D the group this gizmo is in has changed  
          break;  
  }

The way the docs are written. It sort of led me to believe that we had to use Flush to hide/unhide gizmos.
But that's not the case.
