Notes

setupString contains "key=value" pairs that dictate the behavior of the object. Keyname/values are separated by semicolons, and values (per keyname) are separated by commas. For example,

"key1=value1,value2,value3;key2=value1;key3=value1,value2;key4=value1"

To have a literal comma or semicolon inside one of the fields the must be escaped with the carot character.

• ^;
• ^,

For example key/value pairs see the Workplace Shell objects:

• WPColorPalette
• WPDisk
• WPFolder
• WPFontPalette
• WPKeyboard
• WPLaunchPad
• WPPalette
• WPPrinter
• WPRPrinter
• WPProgram
• WPProgramFile
• WPSchemePalette
• WPShadow
• WPObject

All parameters have safe defaults. It is not necessary to pass unnecessary parameters to an object.
