NAME

Gtk2::Ex::TreeModelBits - miscellaneous TreeModel helpers

SYNOPSIS

 use Gtk2::Ex::TreeModelBits;

FUNCTIONS

@values = Gtk2::Ex::TreeModelBits::column_contents ($model, $col)

Return a list of all the values in column number $col of a Gtk2::TreeModel object $model.

Any tree structure in the model is flattened out for the return. A parent row's column value comes first, followed by the column values from its children, recursively, as per $model->foreach.

Gtk2::Ex::TreeModelBits::remove_matching_rows ($store, $subr, ...)

Remove from $store all rows passing $subr. $store can be a Gtk2::TreeStore, a Gtk2::ListStore, or another type with the same style $store->remove method. $subr is called

    $want_remove = &$subr ($store, $iter, ...)

where $iter is the row being considered, and any extra arguments to remove_matching_rows are passed on to $subr. $subr should return true if it wants to remove the row.

The order rows are considered and removed is unspecified, except that a parent row is tested before its children (the children of course tested only if the parent is not removed).

@types = Gtk2::Ex::TreeModelBits::all_column_types ($model)

Return a list of all the column types in $model. For example to create another ListStore with the same types as an existing one,

    my $new_store = Gtk2::ListStore->new
      (Gtk2::Ex::TreeModelBits::all_column_types ($old_store));

OTHER NOTES

If you use an old Gtk 2.0.x and want to pass a Gtk2::ListStore or Gtk2::TreeStore to remove_matching_rows then get Perl-Gtk 1.240 or higher to have the remove method on those Stores return a flag the same as in Gtk 2.2 and up. Otherwise remove_matching_rows will stop after the first row removed.
