Connecting two Figures on a Canvas [message #1007806]

Hi,

I'm using Jubula with an RCP AUT containing a canvas.
I'm dragging and dropping figures from a Tree on the canvas (that works).

However, on the canvas I can usually connect two figures with little Attached Anchors.

I found out the names of those via the GEF Inspector, they are called org.eclipse.graphiti.ui.internal.parts.ContainerShapeEditPart_1/org.eclipse.graphiti.ui.internal.parts.AdvancedAnchorEditPart_1

So it's always the same way, dependent of the name of the Editpart of course.

I want to connect two anchors.
I thought ub_fcv_ClickConnection_byTextpaths would exactly be what I was looking for,
but when I try it, it says the Test failed, it couldn't find the textpaths.
When I try another simple action with the textpath like "Click in Figure", it works.

What is Click Connection doing?

My second approach was to use "Drag and Drop", since it is nearly the same approach, you click on an anchor, and drag it to the second anchor, where you can finally let go of the mouse.
I tried ub_fcv_dragFigure_byTextpath(TEXT,OPERATOR) and fcv_dropOnFigure_by Textpath(TEXT,OPERATOR).
The test suceeds although nothing happened, I guess the drag and drop action is too fast for my AUT.

To get a delay, I choose the version of ub_fcv_dragFigure_byTextpath with the many parameters ( TEXTPATH,OPERATOR,MOUSE_BUTTON,MODIFIER_KEYS,X_POSITION;X_UNITS,Y_POSITION;Y_UNITS)
and ub_fcv_dropFigure_byTextpath(TEXTPATH,OPERATOR,MOUSE_BUTTON,MODIFIER_KEYS,X_POSITION;X_UNITS,Y_POSITION;Y_UNITS,DELAY_BEFORE_DROP).

However, it seems it does not select the Anchor correctly, it is always a bit off the edges. I tried several combinations of X_POSITION/Y_POSITION but nothing worked.

How can I connect my anchors? If that worked, it would be the perfect testing tool;)

Jubula Standalone Version: Version: 1.3.0
on Windows 7.

Thanks for your help in advance,
Virginia

Is it possible that Jubula works too fast for my application? When I start the testcase, it drags the anchor and when I move the mouse a bit during the testcase before the drop happens, the connection line appears and the two figures are connected.
Is there a way to implement this in Jubula? It seems to me that Jubula is kind of too fast.

Hi,

The Click Connection is designed to click an already existing connection, so its not working is correct Wink

I have a feeling that you may need a more specific action than what is currently offered out of the box. Can you add a screenshot of the canvas and information on how the anchors are realised?

HTH,
Alex

Hi,
thank you very much for your reply, unfortunately I didn't notice it earlier.

I have no access to the system at the moment, but I tried to sketch it quickly:

(oh no, I can't use Links yet....well, try this one Smile

i1045.photobucket.com/albums/b455/birkenblatt/screenshot.jpg
There are two (ore more) figures with each of them with an anchor. You can use both for connecting.
When you click (and hold) on one of the anchors, an orange line appears which you can drag to another anchor and drop. Then the real line appears and the connection is made.

With the drag and drop action in Jubula, it selects the right anchor, but that orange line doesn't appear, only when I move the mouse a bit during delay.

I don't know much about the internals, it is just a canvas created with Graphiti as far as I know, and the description of the Anchor in the GEF Inspector is in my first post.

Please ask if you need further details, I would be really happy to solve that problem Smile

Best regards,
Virginia

Oh, and thanks for pointing out what "Click Connection" actually does, I was really wrong.
This action will become important later, but first of all I need to get a connection... Wink

Hi Virginia,

It sounds like the AUT's UI isn't picking up on the mouse's location before dragging and/or dropping. We've had similar sounding drag and drop problems in the past (see https://bxapps.bredex.de/bugzilla/show_bug.cgi?id=129 - full disclosure, that link points to the GUIdancer bugzilla, as this bug was never reported for Jubula). The solution (in code, unfortunately, rather than configuration) was generally what we started referring to as a "mouse shake" (i.e. displacing the mouse cursor slightly and then moving it back in order to ensure that the UI is caught up), which compensates for the general instability of "warping" the mouse cursor from point A to point B with no intermediate stops. The bug that I linked to doesn't describe your problem exactly, but the fix would probably be similar (i.e. "shake" the mouse before dragging, in addition to before dropping).

If this is something reproducible, then it's probably worth filing a bug with Jubula, optimally with a small AUT that demonstrates the problem.

Hey,
that sounds interesting! This is the same as I experienced, it works with a little mouse-shake .
I'll have a closer look to the link and might get back to you, thank you very much!

Hi,
today I had time to have a closer look to your page.
How can I change that in my Jubula, are the class names equal?
And where do I get the code and what do I need to do to get it run, change it, and have it in Jubula finally?
Maybe that sounds like stupid questions, but I'm not experienced in that area.
help would be great!
Greetings,
Virginia

I hope that there is an answer for how to get around this in Jubula, because I am having the same issue in an RCP application. The drop action does not happen until the mouse is manually moved off of the first object; otherwise, the drag cursor just hovers over the first object indefinitely. I cannot find any unbound module in my copy of Jubula that simply performs a "move mouse" action.

Thanks!

I have some more information about my instance of the problem:

Through experimentation, I have discovered that the problem only seems to exist when the figure being dragged is at the right edge of the canvas, and starting to drag it highlights it in a way that increases its horizontal size, such that the canvas scrolls to the right. When the canvas is large enough for everything (including the highlighted figure) to fit on it without scrolling, the drag/drop works as it should.

Hi David,

Thanks for the update on this. I wonder whether Virginia's problem has the same workaround.
As Zeb suggested earlier, you could enter an issue for this - with the description you have given we could try to reproduce it here. If you have a small example AUT that shows the behaviour, even better.

Best regards,
Alex

Hi,

I'm experiencing the same problem as Virginia when trying to connect two figures using Drag and Drop. This is my test case:

Drag:
<ub_fcv_dragFigure_byTextpath> [org.eclipse.graphiti.ui.internal.parts.ContainerShapeEditPart_4/org.eclipse.graphiti.ui.internal.parts.FixPointAnchorEditPart_1, equals, 1, none, 50, percent, 50, percent]

Drop:
<ub_fcv_dropOnFigure_byTextpath> [org.eclipse.graphiti.ui.internal.parts.ContainerShapeEditPart_3, equals, 50, percent, 50, percent, 5000]

The mouse moves onto the second object and stays there, it's as if the drop action never happened. But if I move the mouse during the 5000ms interval, then the connection is successfully made in the diagram.
David's workaround is not applicable to my problem, my canvas is small and the drag&drop action doesn't involve scrolling through the diagram.

Thanks for the updates guys. This is behaviour that doesn't seem to happen in our tests. I don't think anyone has entered an issue for this yet, which would be a good place to add details about Eclipse / SWT version, platform etc. And, like Zeb suggested - if anyone has an example application where it is reproducible, that would help a lot.
