Pull Request Overview
This PR removes legacy port-hover cursor logic to streamline mouse movement handling and improve performance.
- Deletes the idle-state hit-test block that set the cursor when hovering over input ports.
- Removes associated helper methods (
PortFromHitTestResult,ElementUnderMouseCursor,DirectHitTestCallback) and related cursor-setting code.
Comments suppressed due to low confidence (2)
src/DynamoCoreWpf/Views/Core/WorkspaceView.xaml.cs:873
- [nitpick] With the port-hover cursor logic removed, it would be helpful to add tests verifying that the cursor state remains correct during various mouse movements and workspace states to prevent regressions.
// If selection is going to be dragged and ctrl is pressed.
| PortViewModel pvm = PortFromHitTestResult(dependencyObject); | ||
|
|
||
| if (null != pvm && (pvm.PortType == PortType.Input)) | ||
| this.Cursor = CursorLibrary.GetCursor(CursorSet.ArcSelect); |

What does this cursor look like? Is there a png (image file) resource for the cursor that also needs to be removed?

This is how it looks like:
I tried going back to 2.17, 2.15 and still could not see any change in the cursor though, atleast not on hover.

Purpose
Based on the Reope PR: #15825
See original PR's description for a detailed summary.
TLDR; Removing some code from MouseMove event which used to trigger when mouse hover over the input port, at which point the cursor should have been changed to
CursorSet.ArcSelect. But this have not been working since Notes were introduced (May 2023). IMO it is better to go away with it and gain some performance instead.I tried to quantify the gain but it is hard, I tried to capture the amount of processing time spent inside the code while simply hovering over a huge graph, for a difference in CPU usage you can look at the screenshots on the original PR.
(I did see minor gains when selecting nodes in the workspace after this fix)
