Hover outline is having gap on right+bottom side [message #1795186]

Hi

I am facing this gap in my application, but as well in the simple mind map application it can be seen:

index.php/fa/33902/0/

Is this by purpose? Can it be changed?

Hi Frank,

you can try the following code in MindMapNodeVisual and you will see the difference.

shape.setStrokeWidth(5);

shape.setStrokeWidth(5);
shape.setStrokeType(StrokeType.INSIDE);

I think it is casued by the stroke of the shape. The hovered bound has the dimension of the actual size of the shape but it doesn't start at the (minx,miny) of the shape.
I posted a similar question https://www.eclipse.org/forums/index.php/t/1094514/ and it should be the same root cause.

Hello Shenwei

thanks for the hint.
The

 shape.setStrokeType(StrokeType.INSIDE);

helped, thanks.

And your reported problem with the wrong line dimensions also affects my application.

I have the shape with stroke inside, and a line starting from left side at 0.0 (with cap type BUTT), this causes the hover outline to have a gap on the right side.

index.php/fa/33917/0/

When i start that line from 1.0, the outline is good.

Thank you very much for the reports!

I looked into this the other day and thought the issue was only related to stroke, i.e. every non-uniform stroke is incorrectly accounted for by GeometryNode.

However, maybe we can add some logic for the common cases.

I will investigate again...

Best regards,
Matthias
