Description Corey Marthaler 2005-02-24 16:54:45 EST
Description of problem:
I attempted to delete a fence device which was being used by all the
nodes in the cluster and the warning which popped up said it only had
only one dependancy. It took me a second to realize that the warning
message was really a scroll box full of all the nodes dependant on
this device, but only displayed the one. A simple text list would be
far more intuitive since it would display all of them and since
nothing in there is selectable anyway.

will fix
Comment 2 Jim Parsons 2005-03-28 06:24:28 EST
Fixed in 0.9.17-1.0
Comment 3 Corey Marthaler 2005-04-18 14:36:47 EDT
It's still just a scroll box, which displays 5 items (nodes). So when I have 6+
nodes in my cluster, I don't see all the dependancies when deleting the fence
device. This is a pretty low priority request, but I don't think it'd be too
hard to do it right.
Comment 4 Jim Parsons 2005-04-28 10:08:13 EDT
The reason to use a scroll box, is when the size of text or a list to be
displayed is variable.

From the GNOME HIG:
"Often an object (such as a document or a list) will not be fit within the
confines of its viewer control. In these cases a scrollbar can be affixed to the
viewer control. The scrollbar alters which part of the object is currently
visible inside the viewer control: it slides the view across the object in one
axis (horizontal or vertical)."

I do not believe that setting the size of the display area dependent on the size
of the list to be displayed, as on a 50+ node cluster, the display area will
grow beyond the height of the screen for typical resolutions. I am setting the
size of the display area larger in closing this bug again, but strongly believe
that scrollbars is the correct solution here.

BTW, expanded display area is in 0.9.42
