SetBackground(state: VisualizatorControlState; Value: IGxBrush);
state. Control state.
Value. Control background brush.
The SetBackground method determines the brush used to set control background for the specified state.
Executing the example requires that the repository contains an express report with the EXP identifier. The unit containing the example should have links to the Express, Metabase, Drawing and Visualizators system assemblies. The specified procedure should be called from the Main entry point.
Before executing the example, the bubble tree timeline looks as shown on the IVZBubbleTree property description page. Set new values of background and borders for this scale, get type of background brush and width of the border line:
Sub UserProc;
Var
Metabase: IMetabase;
EaxAnalyzer: IEaxAnalyzer;
BubbleTree: IVZBubbleTree;
Timeline: IVZTimeLine;
Style: IVZControlStyle;
Begin
// Get the current repository
Metabase := MetabaseClass.Active;
// Get express report
EaxAnalyzer := Metabase.ItemById("EXP").Edit As IEaxAnalyzer;
// Get bubble tree
BubbleTree := EaxAnalyzer.BubbleTree.BubbleTree;
// Get time line
Timeline := BubbleTree.TimeLine;
// Get timeline style
Style := Timeline.Style;
// Set new background
Style.SetBackground(VisualizatorControlState.ControlStateReleased,
New GxSolidBrush.Create(New GxColor.CreateRGB(127, 199, 255)));
// Set new border color
Style.SetBorderPen(VisualizatorControlState.ControlStateReleased,
New GxPen.CreateSolid(New GxColor.CreateRGB(255, 0, 0), 3));
// Display background color brush type
Select Case Style.GetBackground(VisualizatorControlState.ControlStateReleased).BrushType
Case GxBrushType.SolidColor: Debug.WriteLine("Background fill brush type - SolidColor");
Case GxBrushType.HatchFill: Debug.WriteLine("Background fill brush type - HatchFill");
Case GxBrushType.TextureFill: Debug.WriteLine("Background fill brush type - TextureFill");
Case GxBrushType.PathGradient: Debug.WriteLine("Background fill brush type - PathGradient");
Case GxBrushType.LinearGradient: Debug.WriteLine("Background fill brush type - LinearGradient");
End Select;
// Output border line width
Debug.WriteLine("Border line width: " +
Style.GetBorderPen(VisualizatorControlState.ControlStateReleased).Width.ToString);
// Get express report
(EaxAnalyzer As IMetabaseObject).Save;
End Sub UserProc;
After executing the example, color of background fill and timeline border line are changed in the bubble tree:
Also, the background color brush type and border line width are shown in the development environment console window:
Background color brush type - SolidColor
Border line width: 3
