[Tcl/Tk Utilities] Rendering a clustered digraph twice produces different result (filled clusters)
Ported Issue from Mantis Original ID: 2522 Reported By: csanchezdll
SEVERITY: MINOR Submitted: 2015-03-04 10:25:29
Clusters in a directed graph are rendered by default with black border and transparent background. However, a second (and subsequent) call to render draws the same graph with clusters filled in white.
STEPS TO REPRODUCE
package require Tcldot canvas .c pack .c set g [dotnew digraph] set c0 [$g addsubgraph cluster_0] set n0 [$c0 addnode] set n1 [$c0 addnode] $g addedge $n0 $n1 eval [$g render .c] --> correct result eval [$g render .c] --> incorrect result in second render
