NAME

Top

Gtk2::Ex::EntryBits -- misc functions for Gtk2::Entry widgets

SYNOPSIS

Top

 use Gtk2::Ex::EntryBits;

FUNCTIONS

Top

Gtk2::Ex::EntryBits::select_region_noclip ($entry, $start, $end)

Select text from $start to $end like $entry->select_region, but don't put it on the clipboard. This is a good way to let the user type over previous text, without upsetting any cut and paste in progress.

This is implemented with a nasty hack temporarily pretending $entry is unrealized.

SEE ALSO

Gtk2::Entry, Gtk2::Editable
