hi @m_magalhaes
Yes I am talking about NodeData and the CoreMessage used is not GeDialog::CoreMessage() but is a MessagePlugin MessageData::CoreMessage() which I am using to receive core messages which in this case are the SpecialEvents I have added when clicking Render Button as in below.

Bool RenderSettings::Message(GeListNode* i_node, Int32 i_type, void* i_data)
{
        DescriptionCommand* dc = (DescriptionCommand*)i_data;
	BaseContainer* dldata = ((BaseVideoPost*)i_node)->GetDataInstance();
	switch (i_type)
	{
	case MSG_DESCRIPTION_COMMAND:
	{
                switch (dc->_descId[0].id)
		{
		case RENDER_BUTTON:
		  SpecialEventAdd(START_RENDER);
		  break;
                //Other cases
                 }
        }
}

Now I am catching this special events using CoreMessage function of MessageData. I am doing this way because I need an event telling me when the rendering is finished and this has nothing to do with a NodeData(Which tells me when the rendering starts) or GeDialog as none of this tells me how long does it take for the rendering to finish.

Hello,
I am aware of hiding elements using NodeData::GetDDescription() function, but I need to hide the elements using MessageData::CoreMessage() function.
My scenario is like this:
I am working on an external renderer, and on my render settings when clicking "Render" Button, I would hide that and show "Abort Render" button instead. I have handled this using NodeData::GetDDescription(), but now when the Rendering is finished I want to Hide "Abort Render" button and instead show "Render" button again.
Since I know when the rendering is finished (Adding a special event with ID = DL_RENDER_FINISHED "SpecialEventAdd(RENDERING_FINISHED);", and I can catch this event using CoreMessage() function, I thought it might possible to hide the elements on this function too.

Bool RenderManager::CoreMessage(Int32 id, const BaseContainer &bc)
{
	if (id == RENDERING_FINISHED) 
        {
	     ApplicationOutput("Finished"); //This get's shown exactly after rendering is finished so I know I get the message when I need it. 
             //Need a way to hide an element and show another instead.??
        }
}

Is there any way I can achieve this?
Thank you.

Thank you! That's what I needed.

Hello,
Is there any customGui which adds a ShaderLink to a GeDialog? I noticed that there was some customGui for Links and Texture but I could not find any for ShaderLink.
Thank you.

Thanks @s_bach
This is very helpful.
Best wishes.

Hello,
I was checking on how to add a new tab in the attributes manager using DynamicDescription object but I could only do so if I create all the data by myself. Is there any way that I can do this but from the data that already exist.
Example:
I have a tree-view where you can add different shaders and what I need is that whenever a shader is selected I need to show the attributes of that shader (created in a res file) in the Attributes Manager. Is such a thing possible?
Thank you.

Thanks @zipit,
Managed to solve it thanks to you.

@zipit the reason why I have to use GROUP for every row is because at every row I am adding a popup button. And I can not add it using res file. So I can't do this without a group which tells me where to add the popup button.

Hello,
I have a resource file where I define the UI of materials attributes.

GROUP COATING_LAYER
{
     GROUP THICKNESS_GROUP
     {
	COLUMNS 2;
	REAL COATING_LAYER_THICKNESS{SCALE_H; MIN 0; MAX 1; MINSLIDER 0; 
        MAXSLIDER 1; STEP 0.001; CUSTOMGUI REALSLIDER;}
	SHADERLINK COATING_LAYER_THICKNESS_SHADER{ANIM ON; SCALE_H; HIDDEN;}
     }

     GROUP COLOR_GROUP
     {
	COLUMNS 2;
	COLOR COATING_LAYER_COLOR{SCALE_H;}
	SHADERLINK COATING_LAYER_COLOR_SHADER{ANIM ON; HIDDEN;}
     }
//...Continues with other groups
}

One parameter of the group I specify on the res file as above (The hidden one is not used at all in the UI) and the second parameter I specify using Description object as below.

const DescID* singleid = dc->GetSingleDescID();

	if (!singleid || ((DescID)id).IsPartOf(*singleid, NULL))
	{
		BaseContainer bc = GetCustomDataTypeDefault(DTYPE_POPUP);

		//  Set CycleButton properties
		bc.SetBool(DESC_ANIMATE, false);
		bc.SetInt32(DESC_CUSTOMGUI, CUSTOMGUI_POPUP);
		bc.SetBool(DESC_GROUPSCALEV, TRUE);
		//  Create CycleButton
		return dc->SetParameter(DescLevel(id, DTYPE_POPUP, 0), bc, groupid);
	}

	return TRUE;

The view that I get is the picture below but as you can see the paramters (Thickness, Color, Roughness etc) are not aligned as they normally do when using description resource.
How would the code or res file look like so I can have them aligned.

Hello. I am creating my own custom parameter.
