  • Constructor Details

    • UnitRangeSpecifier

      public UnitRangeSpecifier(Subrange reset)
      Constructor.
      Parameters:
      reset - reset (default) value

  • Method Details

    • createComponent

      public JComponent createComponent()
      Description copied from class: SpecifierPanel
      Abstract method called lazily during getComponent to obtain the graphical component used by this specifier. It will be called a maximum of once. It is not necessary that the component actually be created in this method, for instance it may be created at construction time if that's more convenient.
      Specified by:
      createComponent in class SpecifierPanel<Subrange>
      Returns:
      graphical component

    • getSpecifiedValue

      public Subrange getSpecifiedValue()
      Description copied from interface: Specifier
      Returns the typed value currently specified by the graphical component.
      Returns:
      specified value

    • setSpecifiedValue

      public void setSpecifiedValue(Subrange range)
      Description copied from interface: Specifier
      Sets the typed value represented by the graphical component. Calling this method ought to make it clear to the user what value it is set at; in any case a subsequent call of getSpecifiedValue should yield the same result.

      However if a value is set which is of the correct type but cannot be represented by this specifier, results are unpredictable.

      Parameters:
      range - new value

    • submitReport

      public void submitReport(ReportMap report)
      Description copied from interface: Specifier
      Accepts information about a completed plot that was drawn with input from this specifier. In many cases, the implementation of this method will be a no-op, but it gives this object a chance to update its state or its component's appearance based on the way the plot was actually drawn, which may provide information not otherwise available to this object.
      Parameters:
      report - report of a plot partially specified by this object

    • isSliderActive

      public boolean isSliderActive()
      Returns true if the GUI is currently using the slider control, false if it's using the text fields.
      Returns:
      true iff slider is activated

    • setSliderActive

      public void setSliderActive(boolean isActive)
      Sets the GUI to use the slider rather than the text fields to acquire values.
      Parameters:
      isActive - true for slider, false for text
