Class SubsetConfigManager

java.lang.Object
uk.ac.starlink.topcat.plot2.SubsetConfigManager
public class SubsetConfigManager extends Object
Maintains one configuration component each for a group of RowSubsets. The configuration items are split into two types; normal ones and ones that are centrally managed so that each time a new one is requested it has a different default. A typical usage is to allow a different default colour to be associated with each subset.

    • SubsetConfigManager

      public SubsetConfigManager(NextSupplier nextSupplier, uk.ac.starlink.ttools.plot2.config.ConfigKey<?>[] otherKeys)
      Constructor.
      Parameters:
      nextSupplier - manages dispensing different objects of the same type
      otherKeys - keys for config items not handled by the nextSupplier that should be handled by this managers configgers

  • Method Details

    • getConfigKeys

      public uk.ac.starlink.ttools.plot2.config.ConfigKey<?>[] getConfigKeys()
      Returns the config keys managed by this manager.

    • hasConfigger

      public boolean hasConfigger(RowSubset.Key rsKey)
      Indicates whether this manager currently has an initialised configuration object for the given subset. If not, then calling getConfigger would construct and initialise such an object.
      Parameters:
      rsKey - row subset identifier
      Returns:
      true iff getConfigger would do actual work

    • getConfigger

      public Configger getConfigger(RowSubset.Key rsKey)
      Lazily constructs and returns a SubsetConfigger for a given subset.
      Parameters:
      rsKey - identifier of subset for which the configger is required
      Returns:
      configger

    • setConfig

      public void setConfig(RowSubset.Key rsKey, uk.ac.starlink.ttools.plot2.config.ConfigMap config)
      Adjusts the configuration for a given row subset managed by this object.
      Parameters:
      rsKey - identifier of subset whose configuration characteristcics are to be changed
      config - configuration options to be set; any irrelevant entries are ignored

    • getConfiggerComponent

      public JComponent getConfiggerComponent(RowSubset.Key rsKey)
      Returns the GUI configuration component for a given row subset.
      Parameters:
      rsKey - row subset identifier
      Returns:
      configuration component

    • addActionListener

      public void addActionListener(ActionListener listener)
      Adds a listener to be notified whenever the state of one of this manager's configuration components changes.
      Parameters:
      listener - listener to add

    • removeActionListener

      public void removeActionListener(ActionListener listener)
      Removes a previously added listener.
      Parameters:
      listener - to remove
