How do we select one of the textures in the Texture View window?
The docs say that the images are stored in a GeListHead structure. But there's nothing in the docs that shows how to select them.

  
  Filename fn = Filename("C:\\Users\\user\\Desktop\\myimage.jpg");  
    
  BaseContainer bc;  
  bc.SetFilename(LOADTEXTURE_FILENAME, fn);  
  
  //Loads the image into C4D..But doesn't display it in the texture window!!!  
  PaintTexture *tex = (PaintTexture* )SendPainterCommand(PAINTER_LOADTEXTURE, doc, NULL, &bc);   
  if (!tex) return FALSE;  
  
  //Opens a new Texture View window  
  CallCommand(170103);  
  
  GeListHead *imageList = tex->GetPaintTextureHead();  
  GeListNode *first = imageList->GetFirst();  
  first->ChangeNBit(?, NBITCONTROL_SET);   //<----- How do I select the first image in the texture view window so it shows up in it?

I guess the correct method is BaseList2D->SetBit(BIT_ACTIVE), as GeListNode NBITS / the
selection NBITS are usually used for deeper lying stuff. Might be wrong though, as I have 
never fiddled with Bodypaint classes.

I don't see any way to use SetBit() with this. There's no SetBit() option for GeListNodes.

GetPaintTextureHead() gives us the root. So we should be able use that to traverse the list of textures using things like GetFirst(), GetDown(), GetNext(), etc.
But they don't tell us how to do anything with those children. Like how to select one of them.

Yannick. Are you there?
Can you please ask the developers how we're supposed to do this?
They gave us the GetPaintTextureHead() function so we could use it enable a specific texture in the list. But it's not explained how in the docs.

The GeListHead returns its children which are at least of type GeListNode, but most
objects in c4d which have a user interaction and are of the type GeListNode are also
a BaseList2D, the only exception from that rule i know is the Ckey. As the Bodypaint
classes are all BaseList2D, I suppose the GeListHead will return one of these.

Yannick,

CreateNewTexture() also does the same annoying thing. Where it does not select the the new texture in the Texture View window after it's been created:

    Filename fn = Filename("C:\\Users\\user\\Desktop\\mytex");  
  BaseContainer bc;  
  bc.SetFilename(LOADTEXTURE_FILENAME, fn);  
  bc.SetLong(TEXTURE_FILEFORMAT, FILTER_JPG);  
  bc.SetLong(TEXTURE_WIDTH, 1024);  
  bc.SetLong(TEXTURE_HEIGHT, 1024);  
  bc.SetLong(TEXTURE_MODE, COLORMODE_RGB);  
  PaintTexture *tex = NULL;  
  tex->CreateNewTexture(fn, bc);      //<--Does the same thing...Creates a new texture. But does not select it in the Texture View window!!?

It would be great if there was a way to select these textures so they show up in the texture window.

Try this code. When you are in the BodyPaint layout and viewing the Texture tab it will create a texture and display it.

BaseContainer bc;
bc.SetLong(TEXTURE_FILEFORMAT,FILTER_TIF);
bc.SetLong(TEXTURE_WIDTH, 1024);
bc.SetLong(TEXTURE_HEIGHT, 1024);
bc.SetLong(TEXTURE_MODE, COLORMODE_RGB);
PaintTexture *pTex = PaintTexture::CreateNewTexture("C:\ emp\ extimage.tif",bc);
if(pTex)
{
     PaintLayer *pLayer = pTex->GetFirstLayer();
     if(pLayer && pLayer->IsInstanceOf(OBJECT_PAINTLAYERBMP))
     {
          Bool ret = PaintTexture::SetSelected_Texture((PaintLayerBmp* )pLayer,NULL);
          if(ret)
          {
               //Image should now be selected
          }
     }
}

Thanks. That did the trick.
I didn't realize those textures were also paint layers.

Here's the image loading code I posted earlier. Only now it also selects the loaded image as expected:

    Filename fn = Filename("C:\\Users\\user\\Desktop\\myimage.jpg");      
  BaseContainer bc;  
  bc.SetFilename(LOADTEXTURE_FILENAME, fn);  
  PaintTexture *pTex = (PaintTexture* )SendPainterCommand(PAINTER_LOADTEXTURE, doc, NULL, &bc);  
  if (!pTex) return FALSE;  
  
  if(pTex)  
  {  
      PaintLayer *pLayer = pTex->GetFirstLayer();  
      if(pLayer && pLayer->IsInstanceOf(OBJECT_PAINTLAYERBMP))  
      {  
          Bool ret = PaintTexture::SetSelected_Texture((PaintLayerBmp* )pLayer,NULL);  
      }  
  
      //Opens a new Texture View window  
      CallCommand(170103);  
  }

Thank you kbar.
