MultiSelection

[YauronBis]

From a previous thread. But not solved for me.

Hi.

I have my own navigation pane because they are not native ifc data.
I have all the EntityLabel information I need: Distinct locations, distinct materials, Distinct PropertySets, Distinct Unities, and building element are EACH in a separate TreeList list. Construction Data Treelist is a special hierarchy with the name of IfcType as root, "The typed element" node (when it exists, and if not, a virtual node) as branch, then the elements of construction as a leaf, because that order makes more sense to me.

But when I select a specific location or a typed element, I get all the entityLabel that my selection encompasses (example: all the elements of an certain type, or a list of construction elements typed by the selected object, or the elements of a selected stage) and I want to make a multiple selection in Drawing3dControl with each EntityLabel.

For the moment, the selection works with a bidirectional object on one EntityLabel. I wish I could do the same thing with a lot of EntityLabel now.

How can i do ?
