The
diagLibrary type is used to define all the advanced characteristics of a library of preset shapes used by a Diagram Editor control. The characteristics of this library can be defined and changed using different WLanguage properties.
Remark: For more details on the declaration of this type of variable and the use of WLanguage properties, see
Declaring a variable.
sFile is string = fTempDir() + [ fSep ] + "custom_library.wddiag"
// Creates a library entirely through programming
TempLibrary is Diagram
D1 is diagOval
D1.Width = 50
D1.Height = 50
D1.Background.Color = DarkRed
Add(TempLibrary.Shape, D1)
D2 is diagOval
D2.Width = 50
D2.Height = 70
D2.Background.Color = DarkGreen
Add(TempLibrary.Shape, D2)
// Use the shapes of the temporary diagram to create the library
// Saves the diagram to the disk
DiagramSave(TempLibrary, sFile)
// Load the diagram as a library
MyLibrary is diagLibrary

Properties
Properties specific to diagLibrary variables
The following properties can be used to handle diagLibrary variables:
| | |
| Property name | Type used | Effect |
|---|
| Name | Character string | Name of the shape library. |
| Shape | Array of diagShape | Array of preset shapes. |
Remarks
- By default, shape libraries are displayed in the left panel of the Diagram Editor control.
- The Library property of the Diagram Editor control corresponds to an array of variables of type diagLibrary.
