IMetaAttributesTreeList.ShowLeafFactors

Syntax

ShowLeafFactors: Boolean;

Description

The ShowLeafFactors property determines whether tree elements are displayed.

Comments

Available values:

True. Tree displays attribute hierarchy and elements.
False. Tree displays only attribute hierarchy.

The MetaAttributesTreeList component example with the set value of the ShowLeafFactors property - True (to the left) and False (to the right):

Example

Executing the example requires a form with a button with the Button1 identifier, the MetaAttributesBreadcrumb and the MetaAttributesTreeList components with the MetaAttributesBreadcrumb1 and the MetaAttributesTreeList1 identifiers. 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.ShowLeafFactors := False;

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 tree displays only attributes hierarchy.
