The property VXT_XTERM allows you to override the xterm binary and xterm options (such as color, header, font) when using a runmode xterm_open or xterm_icon. See also the related property VXT_LOG.
For example, the following FDL defines a job to be run in runmode xterm_open (-xt) within the vw wrapper.
T -xt vw sleep 100
P VXT_XTERM xterm -e
The xterm used is an xterm from the user path, without any title or color overrides.
Note: The option -e is currently required by the Runtime software for this feature to work.
For more information, see the section titled "Running jobs in an xterm" in the Flowtracer Developer Manual, which also shows the default values for these properties.
