DiagramObject Attributes

|---|---|---|
|
BackgroundColor |
Long Notes: The background color of the object on the diagram. Set to -1 to re-set to the default color in the model. |
|
|
BorderColor |
Long Notes: The border line color of the object on the diagram. Set to -1 to re-set to the default color in the model. |
|
|
BorderLineWidth |
Long Notes: The border line width of the object on the diagram. Valid values are 1 (narrowest) to 5 (thickest); a default of 1 is applied if an invalid value is passed in. |

|
Bottom |

Setting the Style
The Style attribute contains various settings that affect the appearance of a DiagramObject. However, it is not recommended to directly edit this attribute string. Instead, use either the SetStyleEx method or one of the individual DiagramObject attributes such as BackgroundColor, FontColor or BorderColor.
For example, the Style string might contain a series of values in a format such as:
BCol=n;BFol=n;LCol=n;LWth=n;
where:
- BCol = Background Color
- BFol = Font Color
- LCol = Line Color
- LWth = Line Width
The value assigned to each of the Style color properties is a decimal representation of the hex RGB value, where Red=FF, Green=FF00 and Blue=FF0000.
This code snippet shows how you might change the style settings for all of the objects in the current diagram, changing the background color to red (FF=255) and the font and line colors to yellow (FFFF=65535):
For Each aDiagObj In aDiag.DiagramObjects
aDiagObj.BackgroundColor=255
aDiagObj.FontColor=65535
aDiagObj.BorderColor=65535
aDiagObj.BorderLineWidth=1
