Subject: GraphExplorerComposite now accepts TextTransfer and MOVE/DEFAULT dnd ops
X-Git-Tag: v1.27.0~5
X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=d615f9ce52ccde4f0de408d6345d033faa4590e6;p=simantics%2Fplatform.git

GraphExplorerComposite now accepts TextTransfer and MOVE/DEFAULT dnd ops

TextTransfer must be enabled to allow JSON drops into the model browser.
The MOVE and DEFAULT drag operations are allowed to see if this affects
people with problems dragging files from system file explorer to the
model browser.
