Method Detail

createComponent
public javax.swing.JComponent createComponent()
Description copied from class:SpecifierPanel
Abstract method called lazily duringgetComponent
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 classSpecifierPanel<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 ofgetSpecifiedValue
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
