| Summary : Gtk2 Entry that accepts Pango markup.
|
Description :
\'Gtk2::Ex::Entry::Pango\' is a \'Gtk2::Entry\' that can accept Pango markup
for various purposes (for more information about Pango text markup language
see the http://library.gnome.org/devel/pango/stable/PangoMarkupFormat.html
manpage).
The widget allows Pango markup to be used for input as an alternative to
\'set_text\' or for setting a default value when the widget is empty. The
default value when empty is ideal for standalone text entries that have no
accompanying label (such as a text field for a search).
This widget allows for the text data to be entered either through the
normal methods provided by \'Gtk2::Entry\' or to use the method the
/set_markup manpage. It\'s possible to switch between two methods for
applying the text. The standard \'Gtk2::Entry\' methods will always apply a
text without styles while \'set_markup()\' will use a style.
The widget \'Gtk2::Ex::Entry::Pango\' keeps track of which style to apply by
listening to the signal _changed_. This has some important consequences. If
an instance needs to provide it\'s own _changed_ listener that calls
\'set_markup()\' then the signal _changed_ has to be stopped otherwise the
layout will be lost. The following code snippet show how to stop the
emission of the _changed_ signal:
my $entry = Gtk2::Ex::Entry::Pango->new();
$entry->signal_connect(changed => sub {
my $text = $entry->get_text;
if (validate($text)) {
return;
}
my $escaped = Glib::Markup::escape_text($text);
$entry->set_markup(\"< span underline=\'error\' underline_color=\'red\'>$escaped< /span>\");
$entry->signal_stop_emission_by_name(\'changed\');
});
Another important thing to note is that \'Gtk2::Entry::set_text()\' will not
update it\'s content if the input text is the same as the text already
stored. This means that if set text is called with the same string it will
not emit the signal _changed_ and the widget will not pickup that the
markup styles have to be dropped. This is true even it the string displayed
uses markup, as long as the contents are the same \'set_text()\' will not
make an update. The method the /clear_markup manpage can be used for safely
clearing the markup text.
