From 72542227673047d71c3c3f281e478c1bea82eb81 Mon Sep 17 00:00:00 2001 From: Jussi Koskela Date: Tue, 29 Oct 2019 14:04:28 +0200 Subject: [PATCH] Take zoom level into account when picking connections Also fixed RouteGraphConnectTool.pickNearestRouteGraphConnection which gave flawed results. Visual hints are fixed to match the performed actions. This versions always picks the closest connection if there are multiple hits. gitlab #396 Change-Id: Ib5d8be3b2c7301dae5545166c07e11c03f92a50d --- .../diagram/connection/RouteLine.java | 8 +- .../participant/RouteGraphConnectTool.java | 85 +++++++++---------- .../g2d/diagram/handler/PickRequest.java | 66 ++++++++++++++ .../pointertool/PointerInteractor.java | 55 +++++++----- .../RouteGraphConnectionClass.java | 6 +- .../scenegraph/g2d/G2DSceneGraph.java | 1 + .../g2d/nodes/connection/RouteGraphNode.java | 37 ++++++-- 7 files changed, 179 insertions(+), 79 deletions(-) diff --git a/bundles/org.simantics.diagram.connection/src/org/simantics/diagram/connection/RouteLine.java b/bundles/org.simantics.diagram.connection/src/org/simantics/diagram/connection/RouteLine.java index c32b0ee24..8a73ead7a 100644 --- a/bundles/org.simantics.diagram.connection/src/org/simantics/diagram/connection/RouteLine.java +++ b/bundles/org.simantics.diagram.connection/src/org/simantics/diagram/connection/RouteLine.java @@ -97,11 +97,11 @@ public class RouteLine implements RouteNode, Serializable { public boolean isNear(double x2, double y2, double tolerance) { return isHorizontal ?
