onMoveElements

void onMoveElements(INgProjectEventsOnMoveElementsEvent theEvent)
                    throws IOException,
                           AutomationException

Fires when the user moves a set of elements with the mouse in any view.

Description

The event procedure returns the deltaX and deltaY parameter values that specify the horizontal and vertical translation distance applied to the moved elements (as calculated in user coordinates).

Remarks

When elements are moved by programming using any "Move" method, the custom code specified on this event will be not fired. The OnMoveElements event is only triggered when schematic elements are moved using the GUI tools; that is when end-users move schematic elements using the mouse or the keyboard arrows. So if there are schematic relations as containers between schematics objects contained in a schematic diagram and you develop custom code that use any "Move" method, programming the relations redraw on the INgProjectEvents::OnMoveElements will be completely unuseful. In this case, you must force the relations redraw at the end of the move operations sequence in your custom procedure or customize the SchematicAlgorithmEvents::AfterExecuteAlgorithm event (when the "Move" methods are called during a custom algorithm).

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

Fires when a set of elements is drag-and-dropped in any view.

Description

The event procedure returns the deltaX and deltaY parameter values that specify the horizontal and vertical translation distance applied to the moved elements (as calculated in user coordinates), and the targetX and targetY parameter values that provide the final X and Y coordinates for these moved elements.

Remarks

This callack is fired only when elements are moved when the Drag-an-Drop mode is enabled.

Fires when the user disconnects any link in any view.

Description

The event procedure indicates that the connections of the link ‘link’ in the view ‘view’ have been modified.

When this event is fired, the link which is being disconnected to its initial origin and/or extremity node can:

- have its FromNode and/or ToNode property set to NULL (case of a link which has just been disconnected without being reconnected to other existing nodes)

- have not NULL FromNode and ToNode properties: In the same user operation, the link has been disconnected and reconnected to an existing origin or extremity node.

By default, for disconnecting any link, you must enable the Edit/Move mode and maintain the Ctrl keyboard key pressed. In this case, any link's connection clicked and moved will be graphically modified.

This event is automatically fired before a diagram is opened. By default, if windows are created by Schematics, the view handle number is 0, and the event does not need to be implemented. For more details on the Schematics events' chaining during any diagram opening, please see the Remarks section available from the INgDiagram Open method help-page.

isSessionSavedByFramework

void isSessionSavedByFramework(INgProjectEventsIsSessionSavedByFrameworkEvent theEvent)
                               throws IOException,
                                      AutomationException

Fires when saving any schematic session. Returns TRUE if the session is saved by the framework, and FALSE if this is handled by the application.

Description

By default, when the schematic session is closed, Schematics asks user whether he wants to save the changes or not before closing it. If the IsSessionSavedByFramework event is set to return FALSE, Schematics will not ask anything

Note that if the session's SaveMode property is set, priority is given to this property: thus, if the IsSessionSavedByFramework event is set to return FALSE and if the SaveMode property is set to esriNgSaveByFramework, when the session is closed, user will be asked whether he wants to save the changes or not.

                                      AutomationException

Fires when saving any diagram. Returns TRUE if the diagram is saved by the framework, and FALSE if this is handled by the application.

Description

By default, when a diagram is being closed, Schematics asks user if he wants to save the changes before closing it. If the IsDiagramSavedByFramework event is set to return FALSE for all diagrams, Schematics will not ask whether he wants to save them or not.

Note that if your diagram's SaveMode property is set, priority is given to this property: thus, if the IsDiagramSavedByFramework event is set to return FALSE for all diagrams and if, for a given diagram, the SaveMode property is set to esriNgSaveByFramework, when this diagram is being closed, user will be asked whether he wants to save his changes or not.

The event tells that the view ‘view’ is being destroyed, and indicates that:

- The INgView Close method has been called; that is the fromAPI parameter returns TRUE,

- The view has been closed by clicking the little cross button in the window upper right-hand corner; that is the fromAPI parameter returns FALSE.

By default, if schematic windows are created by Schematics, this event does'nt need to be implemented.

isDigitMadeByFramework

void isDigitMadeByFramework(INgProjectEventsIsDigitMadeByFrameworkEvent theEvent)
                            throws IOException,
                                   AutomationException

Fires when digitizing. Returns TRUE if the digitizing is managed by the framework (that is, the predefined Schematics 'Select element type to create' dialog box opens), and FALSE if this is handled by the application.

Description

Generally, the schematic elements digitizing mode is activated by using the INgProject SetInteractor method, but you can also trigger the predefined CommandSetDigitMode command to activate this mode. In this case, the CommandSetDigitMode triggering automatically opens the predefined 'Select element type to create' dialog box. If you do not want this predefined dialog box to be opened and if you want to open your own applicative dialog box, you need to customize the IsDigitMadeByFramework event.

                      throws IOException,
                             AutomationException

Fires when removing any element in any diagram. Returns TRUE if the element can be removed.

Description

Generally, Schematics applications use this event to remove an element in the database before Schematics graphically removes the related element in the diagrams where it appears (in the case the value returned by the event is TRUE).

Note that an element can be graphically removed without being removed in the database. In this case, updating the diagram at a later stage causes the element to re-appear.

nameOfDigitNode

void nameOfDigitNode(INgProjectEventsNameOfDigitNodeEvent theEvent)
                     throws IOException,
                            AutomationException

Fires when users clicks the 'point' point while the node digitizing mode is enabled for the 'nodeType' type of nodes in the 'Diagram' diagram. Returns the name of the newly digitized node.

Description

This event procedure must be used to specify the name of the 'nodeType' node element type which is being created in the diagram 'diagram' at the 'point' position.

Because of Schematics data-driven philosophy, it is better to create the associated element in the database during the event procedure execution. If you do not create them, your new elements will not be displayed after having updated the diagram or the next time this diagram is opened again.

                     throws IOException,
                            AutomationException

Fires when users clicks on the 'n1' and 'n2' nodes while the link digitizing mode is enabled for the 'LinkType' type of links in the 'Diagram' diagram. Returns the name of the newly digitized link.

Description

This event must be used to specify the name of the 'linkType' link element type which is being created in the diagram 'diagram' between the node ‘n1’ and ‘n2’. The newly created link is attached to the ‘n1’ node via the ‘port1’ link port, and to the ‘n2’ node via the ‘port2’ link port. The ‘pts’ list of points returns the list of intermediate points defined during the digitizing (that is, the list of points defined each time the user has clicked in the background view between the moment the ‘n1’ origin node has been clicked and the moment the ‘n2’ extremity node has been clicked).

As is the case with a digitized node, it is better to create the associated element in the database during the event procedure execution. If you do not create them, your new elements will not be displayed after having updated the diagram or the next time this diagram is opened again.
