Gtk.TreeView - dynamic scrolling
by Philip Wobst-2
::
Rate this Message:
I have a TreeView
with elements that have a date and time column and I would like to have my
application scroll to the position in the TreeView that is nearest to the
current time when the TreeView is displayed. Is there any way of doing this?
Any suggestions would be gladly appreciated. _______________________________________________ Gtk-sharp-list maillist - Gtk-sharp-list@... http://lists.ximian.com/mailman/listinfo/gtk-sharp-list |

I assume you can easily find which row has the closest time. (A simple foreach measuring the distance between Now and the Datetime while keeping track of the lowest value would a simple but ineffective way to get this done.)
Once you have the index of the row you want:
dataGridView1.FirstDisplayedScrollingRowIndex = index;
dataGridView1.Refresh(); Hope that helps,

Sorry for not being clear about this - your solution
describes exactly what I am intending to do - however, I need the solution
for a Gtk.TreeView. (Thanks for the prompt reply) On Wed, Jul 8, 2009

Is there any way of doing this? If you can determine the TreePath of that row (use the model to get this from a TreeIter) then you should be able to use treeView.ScrollToCell(iter, treeView.Columns[0], true, 0, 0) to do this. -- Chris Howie http://www.chrishowie.com http://en.wikipedia.org/wiki/User:Crazycomputers _______________________________________________ Gtk-sharp-list maillist - Gtk-sharp-list@... http://lists.ximian.com/mailman/listinfo/gtk-sharp-list |
