Constructor Detail

TaskElement

public TaskElement(java.lang.String id,
                   java.lang.String elementLabel,
                   int x,
                   int y)

Constructs a TaskElement

Parameters:

id - is the id attribute value of the underlying HTML element

elementLabel - is the label of this task element. It is in fact, the name of this task

x - x position of the task. x is in canvas (DiagramPanel) relative coordinates.

y - y position of the task. y is in canvas (DiagramPanel) relative coordinates.

Method Detail

setMarkerActivated

public void setMarkerActivated(TaskElement.TaskMarkerGraphic m)

Activate the marker m

Parameters:

m -

isTaskMarkerActivated

public boolean isTaskMarkerActivated(TaskElement.TaskMarkerGraphic m)

this method offers a convenient way to determine if a marker is enabled or not

Parameters:

m - the marker which you want to control presence

Returns:

true if the marker is activated, false otherwise

getVisibleTaskMarkers

public java.util.List<TaskElement.TaskMarkerGraphic> getVisibleTaskMarkers()

This method is provided for convenience. It allows to retrieve a collection containing the task markers displayed. It might be useful if you want to check compatibilities between markers before adding a new one.

Returns:

getActivityMarkersActivated

public java.util.List<Activity.ActivityMarkerGraphic> getActivityMarkersActivated()

This method is provided for convenience. It allows to retrieve a collection containing the activity markers displayed.

Specified by:

getActivityMarkersActivated in interface Activity

isActivityMarkerActivated

public boolean isActivityMarkerActivated(Activity.ActivityMarkerGraphic m)

This method returns true if the marker m is activated. Otherwise, it returns false.

Specified by:

isActivityMarkerActivated in interface Activity

setActivityMarkerActivated

public void setActivityMarkerActivated(Activity.ActivityMarkerGraphic m,
                                       boolean enable)

Activate the specified marker, assuming it does not conflict with existing markers

Specified by:

setActivityMarkerActivated in interface Activity

onSvgRefresh

public void onSvgRefresh(com.ebmwebsourcing.gwt.raphael.client.diagram.event.ComplexElementEvent event)

Listen to SVG refreshments.

Specified by:

onSvgRefresh in interface com.ebmwebsourcing.gwt.raphael.client.diagram.event.ComplexElementHandler
