Gantt Events

Note

All Network Events can be used with Gantt diagrams. The event onGeneric is used for this.

An event is fired only when it is bound towards an action.

PARAMETERS is a chain of name-value pairs that is formatted in a certain way. The names can be indexed (for example, labels of nodes whose texts have been changed by the user). The values can consist of lists of entries. The entries can be indexes (for example, a table cell can be represented by a pair, consisting of a row ID and a column ID). The format of the parameter string is configurable, a complex parameter string by default looks like: name1=value1&name2=value2.

onGeneric

Wrapper around all possible and conceivable events, which can wrap each of the actual events. The events mapped using onGeneric are the following:

All Network Events

CUSTOM_COMMAND

Means that an application-specific command has been called (by the user or by an external controller).

Parameter Name	Description
PARAMETER	Standard: string representation of the command Since application-specifc JNet instances can have their own event processing (particularly the case in connection with application events), the parameter is mainly also application-specific.

Parameter Name

Description

PARAMETER

Standard: string representation of the command

Since application-specifc JNet instances can have their own event processing (particularly the case in connection with application events), the parameter is mainly also application-specific.

EDGE_ADDED

Means that a connection has been added to a node, though it still has not been connected to another node.

Parameter Name	Description
Component	Added connection edge
Parameters	NODE	ID of the node to which the connection was added
Parameters	I	Index (0-based) of the new connection in the set of outbound plugs

EDGE_REMOVED

Means that an unlinked connection has been removed

Parameter Name	Description
Component	Removed connection edge
Parameters	NODE	ID of the node from which the connection was removed
Parameters	I	Index (0-based) of the new connection for the quantity of outbound plugs

FRAME_SWITCHED

Means that a SWITCH_FRAME has been executed. The parameter specifies whether the Applet has been removed from the browser window or embedded again.

Parameter Name	Description
PARAMETER	DETACHED, if the browser window has been removed, otherwise EMBEDDED.

JNET_INITIALIZED
Means that a JNet has been removed (the init() method of the Applet).

LINK_CHANGED

Means that the target node of a connection has been changed.

Parameter Name	Description
Component	Newly linked connection edge
Parameters	SOURCE	List of the following entries (in this sequence): ID of the source node of the connection Index (0-based) of the new connection for the quantity of outbound plugs
	TARGET	List of the following entries (in this sequence): ID of the source node of the new connection Index (0-based) of the connection for the quantity of inbound plugs
	OLD	List of the following entries (in this sequence): ID of the source node of the old connection Index (0-based) of the connection for the quantity of inbound plugs of the old target node

MODEL_REMOVED

Means that the model graph has been removed

RECTANGLE_SELECTED

Means that the user has created wit the mouse a rectangle in the background of the character area This event is important for applications that create a new node using the position and size of a rectangle.

If the parameters are coordinates, then they are model coordinates, that is, they are used to correct the current scaling factor,

Parameter Name	Description
Parameter	X	X-coordinate of the top left-hand corner of the selected rectangle
	Y	Y-coordinate of the top left-hand corner of the selected rectangle
	WIDTH	Width of the selected rectangle
	HEIGHT	Height of the selected rectangle
	ROW	Only for Gantt: row ID of the top left-hand corner of the rectangle
	DATE	Only for Gantt: List of start and end dates of the rectangle

ROW_SELECTED

Means that the user has clicked on the header of a table row.

Parameter Name	Description
Component	Table
Parameter	ROW	ID of the clicked row

SELECTION_CHANGED

Means something has been selected or that the selection has been removed.

A click on a component (see on_node_selected , on_edge_selected , or on cells_selected) usually leads to a change in its selection status. Though it is not possible to follow the quantity you just selected only by listening to the click events. This means the user can select a component by clicking on it or reset the selection using the control button. The selection can also be changed using the keyboard (for example CTRL-A to select all) or even by external controllers through the JNet command interface. For this reason this special event is required for making selection changes.

Note that registration for this event can result in a high network load for listeners from other locations.

Parameter Name	Description
Component	Graph or table component in which the selection was changed.
Parameter	NODE	IDs of the selected nodes
	EDGE	IDs of the selected connection edges
	ROW	IDs of the selected table rows (the whole row is selected)
	COL	IDs of the selected table columns (the whole column is selected)
	CELL	When table cells are selected (but not their rows or columns), the area of the selected cells are specified as a list of 4 IDs: rowID-top,colID-left,rowID-bottom,colID-right.
