The arrow heads on the couple links in the genealogy example are
not the same color as the rest of the link. The arrowhead color is
a separate styling property of links,
Color
in the Arrow tab.
When a user selects a link, the rule that determines the color is
the
link:is selected
rule. This rule makes the link color orange, but does not affect
the arrowhead.
Open the genealogy example which you created in Getting started by choosing File > Open and selecting the
appropriate project file if it is not already open.
Note
File > Open can open only
project files.
To include the arrowhead in the color
change:
-
Select the
link:is selectedrule. -
In the Arrow tab, set Color to orange.
-
Switch to Preview Mode to test the result.
-
Select a couple link. The color changes to orange, arrowhead included.
-
Select a node instead and the link color reverts to green.However, the arrowhead does not revert to green.
This result is at first confusing but has
a simple explanation and solution.
The
Color
property for the arrowhead is set to a default value (black)
when the link is created. Therefore black is the color you see
initially for the arrowheads on couple links. If you select a
link and then deselect it, there is no rule explicitly giving
the arrowhead a new color, so it stays orange.
To make sure that the arrowhead is set
back to green:
-
Select the generic link rule.
-
In the Arrow tab, set Color to green.
It is only necessary to set the default value explicitly when
the styling property undergoes a temporary change due to the
state of an object. The possible states are
selected
,
expanded
,
collapsed
, or
legend
for nodes and
selected
or
legend
for links.
Note that not all properties have default
values.
