Hi I'm still reading manuals and learning how to use inkscape , and I discovered the XML editor. And I. Found out how to add links to objects. But now I want to do something a little more advanced. It's doesn't seem like it would be a hard thing to do. I just want to find out how to make an object visible by hovering my mouse over another object. I just don't know how to do it.

Javascript is the way to go. Have you any experience in scripting?

A little bit. Still learning.

I know I'm supposed to type in a code where I highlighted green in this picture https://drive.google.com/file/d/1GLWKpB ... p=drivesdk
And I know for sure what's highlighted yellow is correct. But I don't know the next step

In this particular case you would want to have something like "fill stroke stroke-width". Moving the mouse over the first element will then set the "fill" attribute on the second one to "red", the "stroke" attribute to "black" and the "stroke-width" attribute to "5px". You might also want to set up something for "mouse out" to change the fill and stroke to "transparent".

I'll try it, thanks.
