 +test ! -z "`echo $1 | sed s/[0-9]*//g`" && echo bad panel id  && exit 1
 +
 +CHANNEL=xfce4-panel
 +PANELID=$1
 +PROP=/panels/panel-$PANELID/autohide
 +
 +if `xfconf-query -c $CHANNEL -p $PROP >/dev/null 2>&1`; then
 +    xfconf-query -c $CHANNEL -T -p $PROP
 +else
 +    xfconf-query -c $CHANNEL -n -p $PROP -t bool -s false
 +fi

 +
 +===== Control per-window transparency =====
 +
 +Xfce lets you control the transparency of any window by horizontal scrolling on the titlebar. Starting with 4.12 though, it has been disabled by default. To enable this, open **Settings Editor > xfwm4** and change ''horiz_scroll_opacity'' to true by clicking the checkbox.
