Simulate initial connection using ConnectionCreationTool. [message #89932]

Hi,

I am trying to simulate the initial connection using
ConnectionCreationTool. The way I would like it to work is that if you
right click on a figure a popup menu appears and then once you select one
of the menu items the connection tool is activated and the initial
connection is created. I have the popup menu and activation of the tool
working fine, but I can't simulate the initial connection. Any ideas on
how to do this?

Thanks,

Roberto DeGennaro

....here's how I did it...... and Randy can jump up and down and say it's not
the right way...... but it works :-)
If you have the context menu going then you must have a menu action.... mine
is called ContextMenuConnectionAction. Here is my run() method.....
============================================================ ================
=========
/**
* Set the connection tool as the currently active tool and then create and
dispatch
* a mouse down event over the selected edit part
*/
public void run() {
/**
* Create a mouse down event that thinks it is over the blob and dispatch
it.
* This is a bit of a fudge to mimic what the user ought to do.
*/
IStrutsGraphicalNodeEditPart nodeEditPart =
((IStrutsGraphicalNodeEditPart)getSelectedObjects().get(0));
StrutsGraphicalNodePart modelPart =
((StrutsGraphicalNodePart)nodeEditPart.getModelPart());
Point point = null;
if (modelPart.getPartType() == Wire.STRUTS_GRAPHICAL_ATTRIB_ID) {
point =
((StrutsPolylineConnection)nodeEditPart.getFigure()).getPoin ts().getMidpoint
();
} else {
point = modelPart.getLocation();
}
Point p = new Point(point.x, point.y);
nodeEditPart.getFigure().translateToAbsolute(p);
Canvas canvas = (Canvas)
((StrutsGraphicalEditor)getEditorPart()).getPrimaryViewer(). getControl();
Event event = new Event();
event.button = 1;
event.count = 0;
event.detail = 0;
event.end = 0;
event.height = 0;
event.keyCode = 0;
event.start = 0;
event.stateMask = 0;
event.time = 9516624; // any old time... doesn't matter
event.type = 3;
event.widget = canvas;
event.width = 0;
event.x = p.x + 3;
event.y = p.y + 3;
/**
* Set the connection tool to be the current tool
*/

((DefaultEditDomain)((StrutsGraphicalEditor)getEditorPart()) .getEditDomain()
).setActiveTool(new StrutsGraphicalConnectionTool());
/**
* Dispatch the mouse down event
*/
canvas.notifyListeners(3,event);
}
============================================================ ================
=========

You may have implement a different way of determining a point that targets
the blob on the FFS.

That's one way :-).

Another way would be to subclass ConnectionCreationTool, and create some
method called:
performConnectionStartWith(EditPart sourcePart);

That method would:
1) update the Request
2) Use the request to query the sourcePart for its connection start command
3) Set the current command field on the tool
4) set the tool in STATE_CONNECTION_STARTED.

I think this will work.

If this works, you might submit such code to us, and we could merge it with
the existing code.

Guy I tried it your way and it works great...
Randy I will try it your way when I have time and if I get it to work I
will submit the code...

Thank you both,

Roberto
