Hey Rob,

here is some code provided by Mikael back then which shows how to include a dialog (you can even use dialog resources) :
CustomDataType

That one seems to have slipped by in my searchs. I had a couple others from Mikael that were just the CustomGui without the CustomDataType.

This may be very useful.

Thanks, Samir!

Incidently im trying to make a CustomDataType/Gui, too and the link mentioned by 3D Designer helped me a lot, but i have the same problem mandrake77 described: AllocData is actually never called.

I cant get much info out of his solution ("BaseContainer->InsData ! =)" and "And SetData seems to bew the better choice...."), so im counting on you guys

The GUI part works fine btw and im really happy you discovered this thread, thanks 3D Designer!

ok, maybe i should go a bit more into detail.
i kept very close to the example code (i just changed a few variables and resource ids) and my problems (just like mandrake77's) are:

- in MSASplinePosDialog::SetData(const TriState<GeData> &tristate;) tristate.GetValue().GetType()==DA_NIL and tristate.GetValue().GetCustomDataType(MSA_SPLINEPOS_DATATYPE_ID) returns NULL
- MSASplinePos::AllocData() is never called

please help

I think that I'm in the same boat here. My tristate.GetValue().GetCustomDataType() returns NULL as well and mandrake77's information is uninformative. The best guess that I can give is that he creates the customdata in his plugin's GetDDescription() and inserts it into the BaseContainer there (?). In my case, though, I'm adding my customdatatype/customgui via the resource description file (.res) specifically to avoid GetDDescription() (unless otherwise required).

Here's hoping for Matthias' example soon!

Still not getting things working fully yet - like interactive setting my combobox using the customgui isn't sticking. I have everything in place.

Now onto the juicy bits.

Using Mikael's MSA_SPLINEPOS example, the customgui is using a copy of the customdatatype. But how does one set the actual customdatatype from the copy - especially since the main data is a Vector array? So far, anytime that the AM is switched from then back to this, the data is reset to the customdatatype default information (because the copy hasn't been 'written' to the original). It looks like messaging from the stock SplineData might be the answer (?). I don't know.

Undos. How to do undos on my spline edits? Since the internals of SplineData are hidden, I can only suspect that either real undos are stored for the object with the customdatatype or that it has its own undo history (?). Would a simple AddUndo() setup do the trick here?

Progress is moving forward but at a snail's pace.

Thanks,

Afaik, undos are handled automatically by Cinema 4D for custom descriptions.

Not here. If I add the object and then edit the spline points, an undo removes the object and doesn't undo changes to my spline points. The CUSTOMDATATYPE_INFO_UNDOSAMECUSTOMGUI flag is set for the RegisterCustomDataTypePlugin().

Realize that what I have in my iCustomDataType is the spline 'type', 'count' (number of nodes or knots), and a Vector array containing the nodes/knots. type and count are handled as description resources but the Vector array only exists as such and isn't stored in a Description or BaseContainer.

You have to set the CUSTOMDATATYPE_INFO_UNDOSAMECUSTOMGUI flag for your CustomDataType plugin. Here is the register call of the gradient for instance.

Only use CUSTOMDATATYPE_INFO_UNDOSAMECUSTOMGUI for elelments like the gradient or spline. Simple types don't need and shouldn't use this.

Any idea on how to get the customgui data to the customdatatype? I see that iCustomGui::SetData() is called often whereas iCustomGui::GetData() is never called - so my customgui gets the datatype but can never update it. I have found no way to do this. The only real example that I have for my type of datatype/gui is SplineData/SplineCustomGui but its underlying workings are hidden (as expected).

Come on here. It's coming up on TWO WEEKS since I started this request and I'm still groping in the dark. I can't run a business on R&D; and T&E; in this dismal economic situation. I need support here.

Thank you very much Robert. It seems to do the trick, but it didnt solve it completely. Im stuck where you are.

Concerning the support, i guess ive got sad news for you (if you didnt know already) :

No, I didn't catch that. Well, I'm going the alternative route then with a non-modal dialog and a button in the object's A.M. (the current code has been backed up maybe to be revitalized later). Probably my least palatable solution but I can't wait three weeks or more to get this moving.

Unfortunately i dont really have another choice, since the data im trying to put in the CustomDataType/Gui is needed quite often and adding it to the description everytime would be... overkill.

it supposed to hold five different types of color information...

Sorry to bump this topic again, but another week has passed and my plugin is somewhat useless without the custom datatype... im running out of stuff i can implement without it.
