The MetaAttributesTreeList component example with displayed number of child elements (to the left) and without (to the right):

Example

Executing the example requires a form with a button with the Button1 identifier, the MetaAttributesBreadcrumb component with the MetaAttributesBreadcrumb1 identifier and the MetaAttributesTreeList component with MetaAttributesTreeList1 identifier. The repository must contain a time series database with the OBJ_FC identifier. Click the button to start executing the example.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);

Var

mb: IMetabase;

rubDescr: IMetabaseObjectDescriptor;

dict: IMetaDictionary;

dictInst: IMetaDictionaryInstance;

rub: IRubricator;

rubInst: IRubricatorInstance;

Begin

mb := MetabaseClass.Active;

rubDescr := mb.ItemById("OBJ_FC");

rub := rubDescr.Bind As IRubricator;

rubInst := rubDescr.Open(Null) As IRubricatorInstance;

dictInst := rubInst.GetDictionary(RubricatorDictionary.Facts);

If dictInst <> Null Then

dict := (dictInst As IMetabaseObjectInstance).Object As IMetaDictionary;

MetaAttributesTreeList1.Dictionary := dict;

MetaAttributesTreeList1.ShowCounts := True;

MetaAttributesTreeList1.Breadcrumb := MetaAttributesBreadcrumb1;

MetaAttributesBreadcrumb1.Dictionary := dictInst;

MetaAttributesBreadcrumb1.MetaAttributes := dict.Attributes;

End If;

End Sub Button1OnClick;

After executing the example, the attribute that determines the time series database tree hierarchy that is displayed in the MetaAttributesTreeList component can be selected in the MetaAttributesBreadcrumb component. The number of child elements is displayed for each node.
