Constructor Detail

TextFieldSpecifier

public TextFieldSpecifier(ConfigKey<V> key,
                          V badValue)
Constructor.

Parameters:
key - config key for which this panel will gather values
badValue - value to be returned if a ConfigException is encountered when parsing the entered text
Method Detail

createComponent

protected 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<V>
Returns:
graphical component

getSpecifiedValue

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

Returns:
specified value

setSpecifiedValue

public void setSpecifiedValue(V value)
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:
value - 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
