    • setSelection

      @Deprecated public void setSelection(Object[] selectedValues, String curValue, int[] indices, int index)
      Deprecated.

      Sets the selected items
      Only applicable to choice fields

      Please note that curValue and index are unused as they can be expressed in the selectedValues and indices.

      Parameters:
      selectedValues - an array of objects containing the selected values

      indices - an array of indices
      index - unused

    • setSelection

      public void setSelection(String[] selectedValues, int[] indices, boolean sync)

      indices - An array of indices that reference the optValues. Where the indexes represent the users selection of the options
      sync - Sync this change in selection to the guiComp, if available
      See Also:
      Implementation Note:
      This is version of the method, with a sync variable, is required due to the way that updating a List field works: a list field, when setting its selected indices, will first clear the selection. This clear triggers the state change listener, which calls this method, which calls updateChoiceFieldIndex(), which sets the selected indices and becomes an infinite loop. The inclusion of the sync parameter allows the listener to deny a gui sync, preventing the loop.
