IChart.UndoRedo

Fore Syntax

Fore.NET Syntax

UndoRedo: Prognoz.Platform.Interop.ForeSystem.IUndoRedo;

Description

The UndoRedo property determines parameters of the undo/redo stack in the chart.

Fore Example

Executing the example requires a chart in the regular report with the REGULAR_REPORT identifier. Add links to the Metabase, Chart, Report, Tab system assemblies in the unit.

Sub UserProc;
Var
    Sheet: IPrxSheet;
    MB: IMetabase;
    Report: IPrxReport;
    Chart: IChart;
    UnRed:IUndoRedo;
Begin
    // Get repository
    MB := MetabaseClass.Active;
    // Get regular report
    Report := MB.ItemById("REGULAR_REPORT").Edit As IPrxReport;
    // Get undo/redo stack of regular report
    UnRed:= Report.UndoRedo;
    // Set availability and number of undo/redo stack operations
    UnRed.Enabled:= True;
    UnRed.Limit:= 20;
    (Report As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the Undo/Redo stack is available for the chart; the number of available undo/redo operations is set to 20 operations.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.Chart;
Imports Prognoz.Platform.Interop.Report;
Imports Prognoz.Platform.Interop.Tab;
Imports Prognoz.Platform.Interop.ForeSystem;

Public Shared Sub Main(Params: StartParams);
Var
    Sheet: IPrxSheet;
    MB: IMetabase;
    Report: IPrxReport;
    Chart: IChart;
    UnRed:IUndoRedo;
Begin
    // Get repository
    MB:= Params.Metabase;
    // Get regular report
    Report := MB.ItemById["REGULAR_REPORT"].Edit() As IPrxReport;
    // Get undo/redo stack of regular report
    UnRed:= Report.UndoRedo;
    // Set availability and number of undo/redo stack operations
    UnRed.Enabled:= True;
    UnRed.Limit:= 20;
    (Report As IMetabaseObject).Save();
End Sub;
