Re: GTK Tree View

[Eric Pastoor <epastoor vt edu>]

Thanks for the tip. I just tried that though but it doesn't seem to  
show what I'm looking for

If I have a tree that starts out like:

Root


And I expand on Root so that it looks like
Root
------> Sub Tree A
------> Sub Tree B
------> Sub Tree C

The result of that get_visible_range function is start:0 end: 0

If I expand on Sub Tree A so that i looks like this
Root
------> Sub Tree A
--------------> Child A
------> Sub Tree B
------> Sub Tree C

The result is this: start: 0 end: 0:2


However if only this is visible to the user:
Root
------> Sub Tree A
--------------> Child A
It makes no different on what get_visible_range returns.

Any thoughts?
