From: Jussi Koskela Date: Thu, 5 Sep 2019 10:06:16 +0000 (+0300) Subject: Improved the positioning of issue decoration for connection elements X-Git-Tag: v1.43.0~136^2~79 X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=46cdf23c4ea4733a3acbfd5c9895ec9e65965c7d;p=simantics%2Fplatform.git Improved the positioning of issue decoration for connection elements Shows the issue decorator at a point that belongs to the connection and is closest to the center of its bounding box. Also fixed the updating of position. gitlab #372 Change-Id: Icf948997a9a2ce11a6420d83286144328af4e877 --- diff --git a/bundles/org.simantics.diagram.connection/src/org/simantics/diagram/connection/RouteGraph.java b/bundles/org.simantics.diagram.connection/src/org/simantics/diagram/connection/RouteGraph.java index 62d3de68f..249399d0a 100644 --- a/bundles/org.simantics.diagram.connection/src/org/simantics/diagram/connection/RouteGraph.java +++ b/bundles/org.simantics.diagram.connection/src/org/simantics/diagram/connection/RouteGraph.java @@ -11,13 +11,9 @@ *******************************************************************************/ package org.simantics.diagram.connection;
