Fix resolver #61886

oatkiller · 2020-03-30T20:01:12Z

Summary

This PR fixes several issues with the Resolver graph. The root cause is an SVG which was effecting the layout of the main resolver node. This effected the layout and Resolver's ability to respond to user interactions.

Note

If you have a really big monitor and your browser window is maxed out, you might not be able to reproduce these issues. Try at around 1600px width.

Issues on master

The graph isn't rendering things centered on the origin as expected:

using the panel to center on lsass.exe doesn't center on the lsass.exe node:

The right part of the graph has an SVG element rendered. Clicking and or dragging in that area is non-responsive

@oatkiller this might actually not be true... e.g. when someone switches the active descendant (with the Panel), the tree node doesn't have/get focus until it's returned to its parent composite

I don't understand what you mean. But if you have a better suggestion for this, please let me know. Resolver already has a concept of 'focusing' on a process. It happens when you click the icon in the panel and the graph moves to center the process. This action should probably be combined with that one. Thoughts?

According to the role description for tree, focus and activedescendant are independent concepts. When the user clicks the icon in the panel, the icon should still have input focus, but the Resolver's aria-activedescendant changes to the node's ID and when focus returns to the tree/(Resolver) you assign focus back to the activedescendant node.

With this is mind, my suggestion might be to change this interface name to something like userSelectedResolverNode but we're going to be taking a swipe at this whole active/focus thing soon so feel free to let it ride for now.

Maybe I understand. Basically you're saying that the 'selected' (our definition) resolver node and the focused (DOM's definition) element aren't necessarily (and shouldn't be) the same?

This is the most important change in this PR. Without this style change, the SymbolDefinitions DOM nodes change the size of the resolver graph and effect all the calculations in a negative way.

Asserting that this isn't falsey (it never should be) so that ProcessEventDot doesn't need conditional logic for that case.

assign these directly, as the adjacentNodeMap will always be available

@oatkiller that's OK for level, but aria-flowto can't be empty/null so I think that one still has to be spread

typescript caught this as well. ty
