From 290f621728aa09db5a719f9e7a29d4e342d25425 Mon Sep 17 00:00:00 2001 From: Tuukka Lehtonen Date: Wed, 20 Nov 2019 16:43:29 +0200 Subject: [PATCH] Fixed two selection/picking related bugs 1. RTreeNode bounds calculation now always uses the detailed geometry of district edge nodes to calculate their bounds. This fixes picking to work in cases where the detailed geometry falls much outside of the spanning rectangle of the edge's end vertices. 2. Introduced DistrictSelectionNode that tells G2DParentNode to ignore its bounds instead of nullifying them entirely. This caused the edge nodes to fall outside the R-tree as "boundless nodes" which caused the most optimized R-tree based picking to fail entirely for nodes that are selected when RTreeNode.decompose is executed. gitlab #68 gitlab #69 Change-Id: I119f33a04923b9b4bf06a8229cfccedc520588cb --- .../network/ui/DistrictDiagramViewer.java | 4 ++- .../adapters/DistrictNetworkEdgeElement.java | 4 +-- .../ui/nodes/DistrictNetworkEdgeNode.java | 2 +- .../ui/nodes/DistrictSelectionNode.java | 25 +++++++++++++++++++ 4 files changed, 31 insertions(+), 4 deletions(-) create mode 100644 org.simantics.district.network.ui/src/org/simantics/district/network/ui/nodes/DistrictSelectionNode.java diff --git a/org.simantics.district.network.ui/src/org/simantics/district/network/ui/DistrictDiagramViewer.java b/org.simantics.district.network.ui/src/org/simantics/district/network/ui/DistrictDiagramViewer.java index 0e0a2f52..903c2ffa 100644 --- a/org.simantics.district.network.ui/src/org/simantics/district/network/ui/DistrictDiagramViewer.java +++ b/org.simantics.district.network.ui/src/org/simantics/district/network/ui/DistrictDiagramViewer.java @@ -21,6 +21,7 @@ import org.simantics.district.network.DistrictNetworkUtil;
