+    - For enums that need to be translated, an alias should be created in `parameters.js`, and then use the static class value in your parameter. For example:
+```js
+Enum.XCursorValuePosition = new Enum(
+    QT_TR_NOOP('Next to target'),
+    QT_TR_NOOP('With label'),
+    QT_TR_NOOP('Hidden')
+)

 - `constructor(name = null, visible = true, color = null, labelContent = 'name + value', ...other arguments)`
     - Constructor of the object, should contain at least the name, visible, color, and labelContent that are passed to the super constructor.
     - You should also beaware that Expressions may be inputed as strings or numbers when restored from save, as such you should add a line in your constructor to convert them to an expression.
