public class FigObjectFlowState

extends FigNodeModelElement

Class to display graphics for a UML ObjectFlowState in a diagram.

The Fig of this modelelement may either represent the following UMLelements:

(1) an ObjectFlowState with a Classifier as type, or

(2) an ObjectFlowState with a ClassifierInState as type.

In both cases (1) and (2), the Fig shows the underlined name of the Classifier, and in the latter case (2), it shows also the names of the states of the ClassifierInState.

In the examples in the UML standard, this is written like

      PurchaseOrder
       [approved]
 

The fact that the first line is underlined, and the 2nd not, is the reason to implement them in 2 seperate Figs.

TODO: Allow stereotypes to be shown.

FigObjectFlowState

public FigObjectFlowState()

Main Constructor FigObjectFlowState (called from file loading).

FigObjectFlowState

public FigObjectFlowState(GraphModel gm,
                          Object node)

Constructor FigObjectFlowState that hooks the Fig into an existing UML model element.

Parameters:

gm - ignored!

node - owner, i.e. the UML element

initNotationProviders

protected void initNotationProviders(Object own)

Description copied from class: FigNodeModelElement

Create the NotationProviders.

Overrides:

initNotationProviders in class FigNodeModelElement

Parameters:

own - the current owner

See Also:

FigNodeModelElement.initNotationProviders(java.lang.Object)

modelChanged

protected void modelChanged(PropertyChangeEvent mee)

Description copied from class: FigNodeModelElement

This is called after any part of the UML MModelElement has changed. This method automatically updates the name FigText. Subclasses should override and update other parts.

Overrides:

modelChanged in class FigNodeModelElement

Parameters:

mee - the ModelElementEvent that caused the change

See Also:

FigNodeModelElement.modelChanged(java.beans.PropertyChangeEvent)

updateListeners

protected void updateListeners(Object oldOwner,
                               Object newOwner)

Description copied from class: FigNodeModelElement

Implementations of this method should register/unregister the fig for all (model)events. For FigNodeModelElement only the fig itself is registered as listening to events fired by the owner itself. But for, for example, FigClass the fig must also register for events fired by the operations and attributes of the owner.

An explanation of the original purpose of this method is given in issue 1321.

This function is used in UMLDiagram, which removes all listeners to all Figs when a diagram is not displayed, and restore them when it becomes visible again.

In this case, it is imperative that indeed ALL listeners are updated, since they are ALL removed by the call to removeElementListener.

Additionally, this function may be used by the modelChanged() function.

In this case, it is also imperative that all listeners get removed / added.

Overrides:

updateListeners in class FigNodeModelElement

Parameters:

newOwner - null, or the owner of this. The former means that listeners have to be removed, the latter that they have to be set. TODO: Should this not be boolean, to clarify?

org.argouml.uml.diagram.ui.FigNodeModelElement#updateListeners(java.lang.Object)

placeString

public String placeString()

Description copied from class: FigNodeModelElement

Default Reply text to be shown while placing node in diagram. Overrule this when the text is not "new [UMLClassName]".

Overrides:

placeString in class FigNodeModelElement

Returns:

the text to be shown while placing node in diagram

See Also:

FigNodeModelElement.placeString()

clone

public Object clone()

Description copied from class: FigNodeModelElement

After the base clone method has been called determine which child figs of the clone represent the name, stereotype and port.

The clone function is used by Copy/Paste operations.

Overrides:

clone in class FigNodeModelElement

See Also:

Object.clone()

getMinimumSize

public Dimension getMinimumSize()

Get the minimum size. The space between the 2 text figs is: PADDING.

See Also:

Fig.getMinimumSize()

setBoundsImpl

protected void setBoundsImpl(int x,
                             int y,
                             int w,
                             int h)

Override setBounds to keep shapes looking right. The classifier and state Figs are nicely centered vertically, and stretched out over the full width, to allow easy selection with the mouse. The Fig can only be shrinked to half its original size - so that it is not reduceable to a few pixels only.

See Also:

Fig.setBoundsImpl(int, int, int, int)

renderingChanged

public void renderingChanged()

Description copied from class: FigNodeModelElement

Rerenders the fig.

This functionality was originally the functionality of modelChanged but modelChanged takes the event now into account.

Overrides:

renderingChanged in class FigNodeModelElement

See Also:

FigNodeModelElement.renderingChanged()

setLineColor

public void setLineColor(Color col)

See Also:

Fig.setLineColor(java.awt.Color)

getLineColor

public Color getLineColor()

See Also:

Fig.getLineColor()

setFillColor

public void setFillColor(Color col)

See Also:

getFillColor

public Color getFillColor()

See Also:

Fig.getFillColor()

setFilled

public void setFilled(boolean f)

See Also:

Fig.setFilled(boolean)

getFilled

setLineWidth

public void setLineWidth(int w)

getLineWidth

public int getLineWidth()

Fig.getLineWidth()

keyTyped

public void keyTyped(KeyEvent ke)

Specified by:

keyTyped in interface KeyListener

Overrides:

keyTyped in class FigNodeModelElement

See Also:

KeyListener.keyPressed(java.awt.event.KeyEvent)

textEdited

protected void textEdited(FigText ft)
                   throws PropertyVetoException

Description copied from class: FigNodeModelElement

This method is called after the user finishes editing a text field that is in the FigNodeModelElement. Determine which field and update the model. This class handles the name, and the stereotype, subclasses should override to handle other text elements.

Overrides:

textEdited in class FigNodeModelElement

Parameters:

ft - the FigText that has been edited and contains the new text

Throws:

PropertyVetoException - thrown when new text represents an unacceptable value

See Also:

FigNodeModelElement.textEdited(org.tigris.gef.presentation.FigText)

textEditStarted

protected void textEditStarted(FigText ft)

Description copied from class: FigNodeModelElement

This method is called when the user doubleclicked on the text field, and starts editing. Subclasses should overrule this field to e.g. supply help to the user about the used format.

It is also possible to alter the text to be edited already here, e.g. by adding the stereotype in front of the name, by calling notationProviderName.putValue("fullyHandleStereotypes", true);, but that seems not user-friendly. See issue 3838.

Overrides:

textEditStarted in class FigNodeModelElement

Parameters:

ft - the FigText that will be edited and contains the start-text

See Also:

FigNodeModelElement.textEditStarted(org.tigris.gef.presentation.FigText)

makeSelection

public Selection makeSelection()

Overrides:

makeSelection in class FigNodeModelElement

Fig.makeSelection()
