NAME ^

Gtk2::Ex::ComboBoxBits -- misc Gtk2::ComboBox helpers

SYNOPSIS ^

 use Gtk2::Ex::ComboBoxBits;

FUNCTIONS ^

Active Path

$path = Gtk2::Ex::ComboBoxBits::get_active_path ($combobox)

Return a Gtk2::TreePath to the active item in $combobox, or undef if empty or no model or nothing active.

Gtk2::Ex::ComboBoxBits::set_active_path ($combobox, $path)

Set the active item in $combobox to the given Gtk2::TreePath position. If $path is empty or undef or there's no such row in the model then $combobox is set to nothing active.

Some versions of ComboBox have a feature where if there's no model in $combobox then a toplevel active item is remembered ready for a model set later. Not sure if that's documented, but set_active_path tries to cooperate by using set_active for toplevels, and set_active_iter for sub-rows (which don't get the same remembering).

Text Combos

The following are for use on a simplified "text" ComboBox as created by Gtk2::ComboBox->new_text().

$str = Gtk2::Ex::ComboBoxBits::set_active_text ($combobox, $str)

$combobox must be a simplified "text" type ComboBox. Set the entry $str active.

The corresponding "get" is $combobox->get_active_text(), see Gtk2::ComboBox.

$iter = Gtk2::Ex::ComboBoxBits::find_text_iter ($combobox, $str)

Return a Gtk2::TreeIter which is the row for $str in a text style combobox. If $str is not in $combobox then return undef.

EXPORTS ^

Nothing is exported by default, but the functions can be requested in usual Exporter style,

    use Gtk2::Ex::ComboBoxBits 'set_active_text';

This can be handy if using set_active_text many times. Gtk2::Ex::ComboBox::Text imports it to use as an object method.

There's no :all tag since this module is meant as a grab-bag of functions and to import as-yet unknown things would be asking for name clashes.
