interactions broken on new Makie about graphmakie.jl HOT 3 CLOSED

I tried to look into this a bit. Didn't get to any solution, but the additional info might be helpful.

For the case of node click handlers, nothing happens because of the last if statement below always being false. It seems that a click on a node used to give back the Scatter plot of the nodes, and now it returns a Mesh.

https://github.com/JuliaPlots/GraphMakie.jl/blob/cb19bae27141c32ded7a5ccafc6461edb69dae10/src/interaction.jl#L371-L374

In MakieOrg/Makie.jl#1658 mouse_selection was deprecated for pick, but replacing that doesn't work. Still it might be related. The new point picking docs are here: https://makie.juliaplots.org/stable/documentation/events/#point_picking

So what is this Mesh that it returns, and how do we get the Scatter plot of nodes back with pick (get_node_plot(gp::GraphPlot))?

Thanks for bringing this up. I played around a bit but could not resolve it yet. Using the simple code below you can see that the interactions still work but the reportet elements are infact not the ones below the cursor but a bit offset. However both node and edge interactions work.

Maybe there is some problem with whether the mouse position is calculated with respect to the axis or the figure?

g = wheel_graph(10)
f, ax, p = graphplot(g,
                     edge_width = [2.0 for i in 1:ne(g)],
                     edge_color = [colorant"gray" for i in 1:ne(g)],
                     node_size = [10 for i in 1:nv(g)],
                     node_color = [colorant"red" for i in 1:nv(g)])
hidedecorations!(ax); hidespines!(ax)
deregister_interaction!(ax, :rectanglezoom)

function node_hover_action(state, idx, event, axis)
    p.node_size[][idx] = state ? 20 : 10
    p.node_size[] = p.node_size[] # trigger observable
end
nhover = NodeHoverHandler(node_hover_action)
register_interaction!(ax, :nhover, nhover)

function edge_hover_action(state, idx, event, axis)
    p.edge_width[][idx]= state ? 5.0 : 2.0
    p.edge_width[] = p.edge_width[] # trigger observable
end
ehover = EdgeHoverHandler(edge_hover_action)
register_interaction!(ax, :ehover, ehover)

I checked, and this example now works well on the newly released Makie v0.17.4. Thanks for tracking the issue upstream!
