Shaderlink / Texbox in GeDialog ?

What you want to do does not require having a shader link in the dialog.
All you need is a way to target the specific image or shader type. And then a way to target the specific material you want to add it to.
Also maybe even what channels(color, bump, etc...) do want to add the image to?

For example. One way of doing this is to:
-Use a textbox for the user to enter the target material's name
-Use a Filename gadget to get the image's path on your HD that you want to add to the material.
In your code. You then get the string value from the Filename gadget. And the string value from the textbox. Then use that to insert the image into the target material like this:

   mat = doc.GetFirstMaterial()  
  if mat is None: return False  
  
  file = the string value of your Filename gadget  
  if len(file) == 0: return False  
  
  #Get the specific material based on what the user entered in the textbox  
  #Then add the image file to the color channel's shader link  
  while mat:  
      if mat.GetName() == your textbox value:  
          colorChanel = mat[c4d.MATERIAL_COLOR_SHADER]  
          shdr = c4d.BaseList2D(c4d.Xbitmap)  
          shdr[c4d.BITMAPSHADER_FILENAME] = file  
          mat.InsertShader( shdr )  
          mat[c4d.MATERIAL_COLOR_SHADER]  = sha  
  
      mat = mat.GetNext()

Or.
What about maybe using a combobox gadget to get all of the existing materials rather than a textbox?
Then the user just selects the one they want to add the image to, rather than typing the name.
There's so many ways to do this kind of thing. There's no way to really answer your question.
Don't let the fact that we can't physically have a material link in the dialog get in your way.
Try to think about how you can work around it.

no no...

i wanted to code a helper plugin to setup materials
for that i must be able to select textures and all shaders, noise, layer, etc etc

so i would need a texbox

My point is that there are many ways to do what you want without using the shaderlink custom gui.
For example. You can iterate through a material/materials and get&set the shader links manually.

import c4d  
  
shdrlist = []  
  
def ShaderSearch(shader) :  
  next = shader.GetNext()  
  down = shader.GetDown()   
  if down: ShaderSearch(down)  
  if next: ShaderSearch(next)  
    
  shdrlist.append(shader.GetName())     
  
def main() :  
    
  mat = doc.GetActiveMaterial()  
  if mat is None: return  
    
  shdr = mat.GetFirstShader()  
  if shdr is None: return  
    
  ShaderSearch(shdr)  
  print shdrlist  
    
  c4d.EventAdd()  
    
if __name__=='__main__':  
  main()

Where you get the images or shaders that you want to add. And how you want the user to do that task is relative. All depending on your specific desired workflow.
The shaderlink custom gui might be the most obvious thing to use. But it's not your only option.

For visualizations. I've written dialog plugins that show the active material using a bitmap button to display it. That can be updated by clicking on them. A UserArea could also be used for this. This gets around the limitation of not being able to use a material gadget in a GeDialog.
The sdk as so many options in it that you should be able to do almost anything you want to do. But you might have to do them by hand, instead of using a pre made gadget.

Yes, the TextBox GUI works with the C++ API.

And I've already added TexBoxGui to the Python API todo list

@ ScottA:
i would need to be able to choose from all available shaders in c4d, not from the shaders of a selected material.
the goal is to have the same choice for a shader like when you would be in the material editor itself.

@ Yannick:
good news !
but that probably wont go that fast, will it? .)

Missing classes and functions are regularly added to the Python API.

was there a progress regarding texbox/shader?

does it work to add a texbox/shader in a GeDialog in python by now?

my project is kinda stuck till then...
and i dont even know where i could see a change,
i guess such details are not in the release notes

Such details are in the Python documentation "What's New"
page. Additions to the Python API usually only come with a
new C4D release, so you'll have to wait until R19.

... mhh... i read the news here ...
https://developers.maxon.net/docs/py/2023_2/misc/api_changelist_R19.html

but i think the Shaderlink / Texbox / SHADER gadget inside a dialog wasn't added to the Python API

is that correct and is it still on the todo list?

Hi,

unfortunately the TexBox CustomGUI didn't make it into R19. Sorry. To our excuse, we never said it would.
But at least I can confirm, it is still on our ToDo list.

No excuse needed, it wasn't promised at all

But is there a chance that this gets added in between major releases
(in other words anytime soon-ish) ?

or is it more likely to take a year or two?
(i guess it is not tagged with high priority)
