SOLVED Add Child to description popup field.

Hello. I am creating a parameter description with a popup field but I can not add childs to it. I know that in a GeDialog it is very straightforward AddChild(pop_up_ID,id,name).
Also I managed to add child to a CycleButton CustomGui and I thought it would be very similar to this.

BaseContainer bc = GetCustomDataTypeDefault(DTYPE_LONG);

bc.SetInt32(DESC_CUSTOMGUI, CUSTOMGUI_CYCLEBUTTON);
bc.SetString(DESC_NAME, "Cycle Button");
bc.SetContainer(DESC_CYCLE, settings);
return dc->SetParameter(DescLevel(id, DTYPE_LONG, 0), bc, group_id);

where settings is the container that contains the item names for the cycle.
What would be the equivalent of this for a popup field?
I have tried some options but none of it worked. Also DESC_CYCLE would not work for the items of an popup field.

BaseContainer bc = GetCustomDataTypeDefault(DTYPE_POPUP);

bc.SetInt32(DESC_CUSTOMGUI, CUSTOMGUI_POPUP);
//bc.SetString(DESC_NAME, "Pop Up Button");
//bc.SetContainer(DESC_CYCLE, settings);
return dc->SetParameter(DescLevel(id, DTYPE_POPUP, 0), bc, group_id);

Thank you.

I found the solution. Seems that I had to use MSG_DESCRIPTION_POPUP message to fill the popup field.

hello,

Are you creating your own custom parameter of using an existing one ?

Hello. I am creating my own custom parameter.

hello,

So yes, you have to react to MSG_DESCRIPTION_POPUP, you can see an example on the nodedata manual

I thought first you wanted to create a popup menu.

Cheers,
