[Tile-dev] Error with Treeview

[Joey M. <jo...@sw...>]

I am getting an error when picking the last item in my list when I  
use a tile treeview.

The error is :
invalid command name ".sourcedialog.options.list2"
invalid command name ".sourcedialog.options.list2"
     while executing
"$w identify $x $y"
     (procedure "ttk::treeview::Press" line 3)
     invoked from within
"ttk::treeview::Press .sourcedialog.options.list2 43 188 "
     (command bound to event)


The reason I am getting this error is because I override the Button-1  
as follows:

   bind $listname <Button-1> {
           SourceDialog::OnList [%W item [%W identify row %x %y] -text]
   }

which makes it call my function that goes to the next list.  If I  
pick any other item but the last, it works fine.

If I put the lassign in a catch from treeview.tcl, I can avoid the  
problem.

proc ttk::treeview::Press {w x y} {

     catch {lassign [$w identify $x $y] what where detail} msg
     if {$msg != ""} {
         return
     }

There is probably a better way to solve this.

Thanks,
Joey
