Hello everybody,
I'm currently working on an application, that can read out text files and
make cuesheets out of them (more information on
http://sourceforge.net/projects/audiocuesheet/
http://sourceforge.net/projects/audiocuesheet/ ).
For this, I use a treeview (named "trvMainCuesheet" )with a data model
behind it called "lsCuesheetData".
Now I need to have some tooltip for some rows (if there are errors, and so
on). The tooltip text is stored inside the data model in a not seen column.
Now use the following code, to view the tooltip:
public void prepareTreeViewMainCuesheet()
{
try
{
this.lsCuesheetData = new
ListStore(typeof(Track),typeof(int),typeof(string),typeof(string),typeof(string),typeof(string),typeof(string),typeof(Gdk.Pixbuf),typeof(string));
[...]
this.trvMainCuesheet.Model = lsCuesheetData;
this.trvMainCuesheet.HasTooltip = true;
this.trvMainCuesheet.QueryTooltip +=
queryTooltipTrvMainCuesheet;
}
catch(Exception)
{
throw new NotImplementedException();
}
}
private void queryTooltipTrvMainCuesheet(object o, QueryTooltipArgs args)
{
try
{
TreePath tp;
TreeIter ti;
this.trvMainCuesheet.GetPathAtPos(args.X,args.Y,out tp);
if (tp != null)
{
this.lsCuesheetData.GetIter(out ti,tp);
if (this.lsCuesheetData.GetValue(ti,8) != null)
{
args.Tooltip.Text =
this.lsCuesheetData.GetValue(ti,8).ToString();
args.RetVal = true;
}
}
}
catch(Exception)
{
throw new NotImplementedException();
}
}
My problem is, that I see the tooltip from the row above the one I should
see the tooltip at. I could find out, that this is because in
"trvMainCuesheet" I enabled the "HeadersVisible" option (because the headers
describe the data inside).
So, how can I get around this problem?
Thanks for every help I get ;).
Greetings
Sven
