Moving shadow not the actual item

Hi,

I was wondering if it is possible to move only selected items(nodes/links) shadow not the items themselves so that if the user drags selected item only a shadow moves and the actual items remain at their position itself and when he releases mouse left button the actual items are the moved to the new position and if he happens to right click in between the drag operation should get cancelled.

Please suggest me on how to achieve this with wpfdiagram.

Thanks,
Anurodh

Hi,

There's no built-in support for this. You could implement it using a custom behavior that clones the selected items, sets their colors to semi-transparent ones and starts moving the clones instead of the original items. When the modification is done, delete the clones and move the original items.

I hope that helps,
Stoyan

Hi Stoyan,

We have seen the example shared by you. we want to implement it but it has some issues.

1). If we select multiple nodes, clone effect wont work and one exception is also coming.

2). If select any node to move and now we want to cancel the operation using Escape key, how could we handle this?

3) If node have some link associated with it, they should also display clone effect, but how?

Please suggest.

Regards,
Anshul

Hi Anshul,

https://mindfusion.eu/_beta/wpfdiag_modfeffect.zip

This version adds the Diagram.ModificationEffect property. Set it to MoveShades to see transparent copies of the items while modifying them.

I hope that helps,
Stoyan

Hi Anshul,

We'll have to investigate a couple of bug reports before releasing an official version, if that's what you are asking for. We should release it next week. If you just want to get rid of the "beta" label, we could send you a build of the assembly without that label.

Hi,

1. I think we added the LinkHitDistance property for this. Try setting it to a small value, e.g. 1 point.

2. Yes, that will be included.

3. Doesn't setting Diagram.Behavior = Pan work?

4. 24th of September.

Hi Stoyan,

We are using version 2.1.1.23367 of Mindfusion.Daigramming.Wpf.

1). LinkHitDistance property is not in this version.
2). Diagram.Behavior = Behavior.Pan is not in this version.

Please try to include these two properties in coming version.

Thanks and Regards,
Anshul

Both are available since version 2.2, which we released in July.

Hi Stoyan,

We are using version 2.2.1.

We want Expander button inside the node.(InnerBottom or InnerTop position) as you have written that you would provide support for this too in this built but we are not able to see that here. Could you please tell us when we will get support for it?


Regards,
Anshul

We have added a Custom value to ExpandButtonPosition:

Code
Select All
diagram.ExpandButtonPosition = ExpandButtonPosition.Custom;
diagram.CustomExpandButtonPosition = (n) =>
{
	Rect r = n.Bounds;
	r.X = r.Width - 12;
	r.Y = r.Height - 12;
	r.Width = r.Height = 12;
	return r;
};


I hope that helps,
Stoyan

Hi Stoyan,

Thanks for the reply. We will try to implement it.

We have 2 queries regarding ModificationEffect.
1). We want to display only border of the selected object on MoveShades. Currently it is displaying opaque image of the object. We want only outline.

2). while dragging if we press escape button, we want operation get canceled and node should be move to their original position. Is it possible?

Please suggest us for these two issues.

Regards,
Anshul
