Hi everyone,

I was wondering if there is anything in the SDK for Python or C++ to access HUD elements. All I'm looking to do at this stage is have control of the positions of HUD objects like a user data slider or an info string.

Hi Adam,

It's currenly only possible to access the HUD elements (or controls) with the C++ API. Note the library lib_viewport.h that enables this access isn't documented and doesn't appear in the documentation. See this header to know its definitions.
Here's a simple code snippet to access an existing HUD added to an integer user data with ID 1:

AutoAlloc<ViewportHUD> viewHUD;
if (!viewHUD)
  return false;
ViewportHUDControl* control = viewHUD->FindControl(doc, doc->GetActiveBaseDraw(), op, DescID(DESCID_DYNAMICSUB, DescLevel(1, DTYPE_LONG, 0)));
if (!control)
  return false;

doc is the active document and op the active object.

Then to control the position ViewportHUDControl has the method SetTopLeft().
