Method Details

getDefaultParameters

public List<Parameter> getDefaultParameters()

Description copied from interface: PreferencesInterface

On first start or on reset there will be no preferences available. The PreferenceManager will read this list containing the set of settings, that the implementing class thinks can be configured provide default values. All Parameters in this list will also appear in the PreferenceDialog. Entities providing preferences should add parameters to this array.

Specified by:

getDefaultParameters in interface PreferencesInterface

updatePreferences

public void updatePreferences(Preferences preferences)

Description copied from interface: PreferencesInterface

This method will be called, when preferences for this class have changed and the implementing class gets the chance of setting class (static) variables having the values of the parameters. Setting static class variables will help increase speed, when querying the parameters. Direct variable access VS querying the Preferences Object for this class

Specified by:

updatePreferences in interface PreferencesInterface

getPreferencesAlternativeName

public String getPreferencesAlternativeName()

Description copied from interface: PreferencesInterface

return a custom preference category, that this class will reside in. If null is returned, this class will be put into a standard category dependent on its Super class

Specified by:

getPreferencesAlternativeName in interface PreferencesInterface

Returns:

highlight

public void highlight(boolean value,
MouseEvent e)

Overrides:

highlight in class AttributeComponent

setAttribute

public void setAttribute(Attribute attr)

obvious

Overrides:

setAttribute in class AbstractAttributeComponent

Parameters:

attr -

attributeChanged

public void attributeChanged(Attribute attr)

Called when an attribute of the attribute represented by this component has changed.

Specified by:

attributeChanged in interface GraffitiViewComponent

Specified by:

attributeChanged in class AbstractAttributeComponent

Parameters:

attr - the attribute that has triggered the event.

Throws:

ShapeNotFoundException - DOCUMENT ME!

recreate

public void recreate()

Used when the shape changed in the datastructure. Makes the painter create a new shape.

Specified by:

recreate in class AbstractAttributeComponent

Throws:

ShapeNotFoundException - DOCUMENT ME!

paint

public void paint(Graphics g)

Overrides:

paint in class AbstractAttributeComponent

adjustComponentSize

public void adjustComponentSize()

Description copied from class: AttributeComponent

adjust the component size and position

Overrides:

adjustComponentSize in class AbstractAttributeComponent

adjustComponentPosition

public void adjustComponentPosition()

Description copied from class: AttributeComponent

adjust the component position only

Overrides:

adjustComponentPosition in class AbstractAttributeComponent

updateLabelPosition

public void updateLabelPosition()

Using the information from the associated LabelAttribute and the shape and position of the GraphElement to calculate and set the position of the label.

getBestAutoOutsideSetting

public static String getBestAutoOutsideSetting(Node n)

getLabelFrameSetting

public LabelFrameSetting getLabelFrameSetting()
