UI::Dialog::Backend::CDialogSYNOPSIS¶
use UI::Dialog::Backend::CDialog; my $d = new UI::Dialog::Backend::CDialog ( backtitle => 'Demo', title => 'Default' );
$d->msgbox( title => 'Welcome!', text => 'Welcome one and all!' );
ABSTRACT¶
UI::Dialog::Backend::CDialog is the UI::Dialog backend for the console dialog variant. While this module is used through UI::Dialog or any other loader module only the compatible methods are ever accessible. However, when using this module directly in your application (as in the SYNOPSIS example) you are given access to all the options and features of the real dialog(1) application.DESCRIPTION¶
There are essentially two versions of the console dialog program. One has support for colours as well as extra widgets, while the other does not have either. You can read about the colour support in the TEXT MARKUP section.EXPORT¶
None

- DESCRIPTION
End the meter bar widget process. One of the
flaws with gdialog is that the gauge widget does not close properly and
requies the end user to close the gauge window when 100% has been reached.
This is the second reason why I'm glad gdialog is going the way of the
dodo.

TRUE (1) if the widget closed fine and FALSE
(0) for anything else.
