IVZDataVisualizer.HoverActiveEffects

Syntax

HoverActiveEffects: IVZEffects;

Description

The HoverActiveEffects property determines effects applied to the hovered element.

Comments

To set up effects, use properties of the IVZBrushEffect, IVZBorderEffect, IVZAlphaChannelEffect interfaces.

Example

Executing the example requires that the repository contains an express report with the EXPRESS identifier.

Add links to the Drawing, Express, Metabase, Visualizators system assemblies.

Sub userProc;
Var
    Metabase: IMetabase;
    EaxAnalyzer: IEaxAnalyzer;
    EMap: IVZMapChart;
    BrEffect: IVZBrushEffect;
    BoEffect: IVZBorderEffect;
    Color: IGxColor;
    Feather: IGxPen;
Begin
    Metabase := MetabaseClass.Active;
    EaxAnalyzer := Metabase.ItemById("EXPRESS").Edit As IEaxAnalyzer;
    // Get express report map as a visualizer
    EMap := EaxAnalyzer.MapChart.MapChart;
    // Set up fill
    BrEffect := New VZBrushEffect.Create;
    Color := New GxColor.CreateRGB(255,255,255);
    BrEffect.BackgroundBrush := New GxSolidBrush.Create(Color);
    // Set up borders
    BoEffect:= New VZBorderEffect.Create;
    Color := New GxColor.CreateRGB(0,0,0);
    Feather := New GxPen.CreateSolid(Color,2);
    BoEffect.BorderPen := Feather;
    // Determine effect on mouse over the active element
    EMap.HoverActiveEffects := New VZEffects.Create;
    EMap.HoverActiveEffects.Add(BrEffect);
    // Determine effect on mouse over the inactive element
    EMap.HoverInactiveEffects := New VZEffects.Create;
    EMap.HoverInactiveEffects.Add(BoEffect);
    // Determine effect of active element selection
    Color := New GxColor.CreateRGB(255,0,0);
    BrEffect.BackgroundBrush := New GxSolidBrush.Create(Color);
    EMap.SelectActiveEffects := New VZEffects.Create;
    EMap.SelectActiveEffects.Add(BrEffect);
    // Determine effect of inactive element selection
    Color := New GxColor.CreateRGB(0,255,0);
    BrEffect.BackgroundBrush := New GxSolidBrush.Create(Color);
    EMap.SelectInactiveEffects := New VZEffects.Create;
    EMap.SelectInactiveEffects.Add(BrEffect);
    (EaxAnalyzer As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the following effects are set:

Active area is filled with white on mouse over.

Inactive area is bordered with black on mouse over.

Active area is filled with red on selection.

Inactive area is filled with green on selection.
