20.5.541
  • Implemented <scriptMenuStripDynamic> element type for XMLMenus used in

Qt/Python code (e.g. the python panels). This allows a script to generate a sequence of scripted entries in the menu. The <contentsscriptcode> is evaluated, and therefore the entries are generated, when the menu is opened, not when it is initially parsed.

  • Fix handling of all <scriptcode> elements to allow for single line python

expressions. Also allow multiline code to be indented.

  • menupy.xsd has been updated to allow <scriptMenuStripDynamic>.
