Not exactly. It's more like with limited resources, the squeaky
wheels get the first greasing. Since neither Paul or I have needed
the control, and no one on the list has complained about it, we've
focused on other things. But now that you've brought it up, it's
probably time to spend some time on it.

dSplitter is what you need.

This can be handled by dListControl, dListBox, or dGrid.

Both dListControl and dGrid can color individual rows. dGrid could
do the sort of coloring depicted in that image, but you'd need to
create a custom renderer class.

Supposedly this is possible with dGrid, but I haven't had success,
even working at the wxPython level. I don't see anything in the
wx.ListCtrl that will allow this.

No problem.
grd.ShowCellBorders = grd.ShowColumnLabels = False.

Just make a single column, and set col.Expand = True.

This would fall into the realm of a custom renderer.

Sounds like neither is perfect, but that you'd come closer with a grid.
