Style

Variant

See Setting the Style.

Method

Remarks

GetLastError()

String

Notes: Returns a string value describing the most recent error that occurred in relation to this object.

ResetFont

Notes: Resets the font of the object text on the diagram back to the model default.

SetFontStyle(FontName,
FontSize,
Bold,
Italic,
Underline)

Boolean

Notes: Sets the font of the object text on the diagram to the specified values.

SetStyleEx(string Parameter, string Value)

Void

Notes: Sets an individual parameter of the Style string.

Parameters:

  • Parameter: String - the name of the style parameter to modify; for example:
         "BCol" = background color
         "BFol" = font color
         "LCol" = line color
         "LWth" = line width
  • Value: String - the new value for the style parameter

Update()

Boolean

Notes: Updates the current DiagramObject after modification or appending a new item

If False is returned, check the GetLastError function for more information.

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

             aDiagObj.Update

             aRepos.ReloadDiagram aDiagObj.DiagramID
