Subject: smyrna on_attrAddBtn_clicked: use const type to squash a -Wcast-qual warning
X-Git-Tag: 5.0.1~29^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ef343e1cea0f735a8bb8eae837f478bcd6f7e824;p=graphviz

smyrna on_attrAddBtn_clicked: use const type to squash a -Wcast-qual warning

Unfortunately we cannot also do the same for `attr_name` in this function
because it is passed to a Graphviz function that accepts a non-const pointer.
