Creates a new Gtk2::Ex::Simple::List object with the specified columns. The parameter "cname" is the name of the column, what will be displayed in the list headers if they are turned on. The parameter ctype is the type of the column, one of:

 text    normal text strings
 markup  pango markup strings
 int     integer values
 double  double-precision floating point values
 bool    boolean values, displayed as toggle-able checkboxes
 scalar  a perl scalar, displayed as a text string by default
 pixbuf  a Gtk2::Gdk::Pixbuf

or the name of a custom type you add with "add_column_type". These should be provided in pairs according to the desired columns for your list.

Like "Gtk2::Ex::Simple::List->new()", but turns an existing Gtk2::TreeView into a Gtk2::Ex::Simple::List. This is intended mostly for use with stuff like Glade, where the widget is created for you. This will create and attach a new model and remove any existing columns from treeview. Returns treeview, re-blessed as a Gtk2::Ex::Simple::List.

Set the data in the list to the array reference $arrayref. This is completely equivalent to @{$list->{data}} = @{$arrayref} and is only here for convenience and for those programmers who don't like to type-cast and have static, set once data.

Returns an array ref with the data of the row indicated by $path.

Select or unselect rows in the list by index. If the list is set for multiple selection, all indices in the list will be set/unset; otherwise, just the first is used. If the list is set for no selection, then nothing happens.

To set the selection mode, or to select all or none of the rows, use the normal TreeView/TreeSelection stuff, e.g. $slist->get_selection and the TreeSelection methods "get_mode", "set_mode", "select_all", and "unselect_all".

This is a very simple interface to Gtk2::TreeView's editable text column cells. All columns which use the attr "text" (basically, any text or number column, see "add_column_type") automatically have callbacks installed to update data when cells are edited. With "set_column_editable", you can enable the in-place editing.

"get_column_editable" tells you if column index is currently editable.

Add a new column type to the list of possible types. Initially six column types are defined, text, int, double, bool, scalar, and pixbuf. The bool column type uses a toggle cell renderer, the pixbuf uses a pixbuf cell renderer, and the rest use text cell renderers. In the process of adding a new column type you may use any cell renderer you wish.

The first parameter is the column type name, the list of six are examples. There are no restrictions on the names and you may even overwrite the existing ones should you choose to do so. The remaining parameters are the type definition consisting of key value pairs. There are three required: type, renderer, and attr. The type key determines what actual datatype will be stored in the underlying model representation; this is a package name, e.g. Glib::String, Glib::Int, Glib::Boolean, but in general if you want an arbitrary Perl data structure you will want to use 'Glib::Scalar'. The renderer key should hold the class name of the cell renderer to create for this column type; this may be any of Gtk2::CellRendererText, Gtk2::CellRendererToggle, Gtk2::CellRendererPixbuf, or some other, possibly custom, cell renderer class. The attr key is magical; it may be either a string, in which case it specifies the attribute which will be set from the specified column (e.g. 'text' for a text renderer, 'active' for a toggle renderer, etc), or it may be a reference to a subroutine which will be called each time the renderer needs to draw the data.

This function, described as a GtkTreeCellDataFunc in the API reference, will receive 5 parameters: $treecol, $cell, $model, $iter, $col_num (when SimpleList hooks up the function, it sets the column number to be passed as the user data). The data value for the particular cell in question is available via $model->get ($iter, $col_num); you can then do whatever it is you have to do to render the cell the way you want. Here are some examples:

  # just displays the value in a scalar as 
  # Perl would convert it to a string
  Gtk2::Ex::Simple::List->add_column_type( 'a_scalar', 
          type     => 'Glib::Scalar',
          renderer => 'Gtk2::CellRendererText',
          attr     => sub {
               my ($treecol, $cell, $model, $iter, $col_num) = @_;
               my $info = $model->get ($iter, $col_num);
               $cell->set (text => $info);
          }
     );

  # sums up the values in an array ref and displays 
  # that in a text renderer
  Gtk2::Ex::Simple::List->add_column_type( 'sum_of_array', 
          type     => 'Glib::Scalar',
          renderer => 'Gtk2::CellRendererText',
          attr     => sub {
               my ($treecol, $cell, $model, $iter, $col_num) = @_;
               my $sum = 0;
               my $info = $model->get ($iter, $col_num);
               foreach (@$info)
               {
                   $sum += $_;
               }
               $cell->set (text => $sum);
          } 
     );
