I did read a little about the CustomGuiData and CustomDataTypeClass, but I'm still fighting with it.
What I want to do: In the description of my material I want to show a TreeView. So far I did lear, that I have to define my own CustomGuiData, which returns a CDialog*, within that one I will have to return my TreeView. The function of it will somehow be compareable with MATASSIGN. It only shows some actual states, but they dont need to be saved to the container. So, do I need a CustomDataTypeClass for the CustomGuiData, or is that not necessary? Can I acess member variables of my material from CustomDataTypeClass? My material contains a list of many basebitmaps and a name for each one. This list is a member variable, is loaded by the material and even saved to an own specific format. Within the TreeView I just want to show the actual assignment of that list, the names according to each bitmap. I want to use a TreeView, because later it can be thousands of little bitmaps within the material, so I want to group the names to several packets, just for a better overview.
A short description of the steps I will have to do would be nice.

So far I found out: You always need a CustomGuiData AND an according CustomDataTypeClass with it.
I continue working on it, if I know how all of that works, I'll post a howto

With the source code I'm going on, and my plugin nearly works now. Only one problem is left: The data connection between the data type and the gui. The gui receives data with Bool iGlyphListGui::SetData( const TriState<GeData>& tristate ). I tried to understand in in the example above, I even did compile it, but in the MSA occures the same problem that I have....tristate does not contain data. Before I tried it I thought, SetData receives a GeData, so maybe within my datatype I have to wrap my data into a GeData within ConvertToGeData....but this function is never called.

Sorry, I don't understand what the problem could be. The code was literaly pasted from the latest MSA version. What do you mean by "tristate does not contain data"? That tristate.GetValue().GetType()==DA_NIL? Or that tristate.GetValue().GetCustomDataType(YOUR_ID) returns NULL?

Yes, in the MSA example the type is DA_NIL, and GetCustomDataType returns a NULL pointer. I even compiled the above code with it, the result is the same. In fact I dont understand the mechanism how it should work, to receive data, I should first somewhere have to define, what data is put into GeData, but I have no idea where!
