Question

I want to highlight specific rows in a gtk.Table. I also want a mouseover to highlight it w/ a different color (like on a link in a web browser). I thought of just packing each cell with an eventBox and changing the STATE_NORMAL and STATE_PRELIGHT bg colors, which does work, but mousing over the eventbox doesn’t work. Is there a better way?

This seems to work:

    def attach(w,c1,c2,r1,r2):
        eb = gtk.EventBox()
        a = gtk.Alignment(xalign=0.0,yalign=0.5)
        a.add(w)
        eb.add(a)
        eb.set_style(self.rowStyle)
        def ene(eb,ev):
            eb.set_state(gtk.STATE_PRELIGHT)
        def lne(eb,ev):
            eb.set_state(gtk.STATE_NORMAL)
        eb.connect('enter-notify-event', ene)
        eb.connect('leave-notify-event', lne)

        self.table.attach(eb, c1, c2, r1, r2,
                          xoptions=gtk.EXPAND|gtk.FILL,
                          yoptions=gtk.SHRINK)

It only highlights each cell at a time, so I’ll have to change the notify events to light up everything.

EDIT: self.rowStyle is set as follows:

tmpeb = gtk.EventBox()
st = tmpeb.get_style().copy()
st.bg[gtk.STATE_PRELIGHT] = gtk.gdk.Color(65535,65535,0)
self.rowStyle = st

I create an EventBox just to get its style.
