Gantt Events

Note Note

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

An event is only fired if it is bound to an action.

End of the note.

PARAMETERS is a string of name/value pairs that has a specific format. The names can be indexed (for example, the labels of a node whose texts have been changed by the user). The values may consist of lists of entries. The entries may be indexes (for example, a table cell can be represented by a pair, consisting of a row ID and column ID). The format of the parameter string can be configured; a complex parameter string usually looks like: name1=value1&name2=value2 ...

onGeneric

All Network Events

CUSTOM_COMMAND

Wrapper for all possible events that could wrap the actual events. The following events are mapped across onGeneric:

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

Parameter Name	Description
PARAMETER	Default: String representation of the command Since application-specific JNet instances can have a separate event processing (in particular in connection with application events), the parameter is also mostly application-specific.

Parameter Name

Description

PARAMETER

Default: String representation of the command

Since application-specific JNet instances can have a separate event processing (in particular in connection with application events), the parameter is also mostly application-specific.

EDGE_ADDED

Indicates that a link has been added to a node, but is not yet linked to another node.

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

EDGE_REMOVED

Indicates that an unbound connection has been removed

Parameter Name	Description
Component	Removed connection edge
Parameter	NODE	ID of node where the connection was removed
Parameter	I	Index (0-based) of the new connection in the set of outbound plugs

FRAME_SWITCHED
Indicates that a SWITCH_FRAME was executed This parameter specifies whether the Applet was detached from the browser window or embedded again.

Parameter Name

Description

PARAMETER

DETACHED, if the browser windo was detached, otherwise EMBEDDED.
JNET_INITIALIZED
Indicates that a JNet has been triggered (the init() method of the Applet).

Parameter Name	Description
PARAMETER	DETACHED, if the browser windo was detached, otherwise EMBEDDED.

LINK_CHANGED

Indicates that a target node of a connection has been changed.

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

MODEL_REMOVED
Indicates that the model graph has been removed.

RECTANGLE_SELECTED

Indicates that the user has created with the mouse a rectangle on the background of the character range. This event is needed for applications that create a new node using the position and size of a rectangle.

If the parameters are coordinates, they are model coordinates, which means that are used for correcting the current scaling factor.

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

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

Parameter Name

Description

Component

Table

Parameter

ROW

ID of the clicked row

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

SELECTION_CHANGED

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

A click on a component (see on_node_selected, on_edge_selected, or on cells_selected) usually results in a change to its selection status. But it is not possible to trace the set just selected just by listening to the click events. This means that the user can select a component by clicking on it or cancel the selection with the control button. The selection can also be changed using the keyboard buttons (e.g. CTRL-A to select all), or even by external controllers through the JNet command interface. For this reason this special event is required for selection changes.

Note that the registration for this event can mean a high network workload for listeners in other locations.

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