NAME

gbsddialog — Gtk+ dialogs

SYNOPSIS

gbsddialog --help | --version

gbsddialog [--option] --dialog text rows cols [dialog-argument] [--option]

gbsddialog ... --dialog1 ... [--and-dialog --dialog2 ...] ...

DESCRIPTION

The gbsddialog utility builds graphical User Interface dialogs and widgets.

The option --help prints a brief list of features and exits. The option --version prints the version and exits. The option --and-dialog builds another dialog unless the previous one returns Error, ESC or Cancel.

Each dialog accepts text to print a message inside, rows and cols to set height and width, 0 for autosize and -1 for fullscreen.

The possible input from the user interface is printed to standard error at exit.
