GUI::HELPERS - helper functions for TinyCA, doing small jobs related to the
GUI
=head1 SYNOPSIS
use GUI::HELPERS;
GUI::HELPERS::print_info($text, $ext);
GUI::HELPERS::print_warning($text, $ext);
GUI::HELPERS::print_error($text, $ext);
GUI::HELPERS::sort_clist($clist, $col);
GUI::HELPERS::set_cursor($main, $busy);
GUI::HELPERS::browse_file($main, $entry, $mode);
GUI::HELPERS::set_status($main, $text);
$box = GUI::HELPERS::dialog_box(
$title, $text, $button1, $button2);
$label = GUI::HELPERS::create_label(
$text, $mode, $wrap, $bold);
$row = GUI::HELPERS::label_to_table(
$key, $val, $table, $row, $mode, $wrap, $bold);
$entry = GUI::HELPERS::entry_to_table(
$text, $var, $table, $row, $visibility, $box);
=head1 DESCRIPTION
GUI::HELPERS.pm is a library, containing some useful functions used by other
TinyCA2 modules. All functions are related to the GUI.
=head2 GUI::HELPERS::print_info($text, $ext);
=over 1
creates an Gtk2::MessageDialog of the type info. The string given in $text is
shown as message, the (multiline) string $ext is available through the
"Details" Button.
=back
=head2 GUI::HELPERS::print_warning($text, $ext);
=over 1
is identically with GUI::HELPERS::print_warning(), only the
Gtk2::MessageDialog is of type warning.
=back
=head2 GUI::HELPERS::print_error($text, $ext);
=over 1
is identically with GUI::HELPERS::print_info(), only the Gtk2::MessageDialogog
is of type error and the program will shut down after closing the message.
=back
=head2 GUI::HELPERS::sort_clist($clist, $col);
=over 1
sorts the clist with the values from the given column $col.
=back
=head2 GUI::HELPERS::dialog_box($title, $text, $button1, $button2);
=over 1
returns the reference to a new window of type Gtk2::Dialog. $title and
$button1 must be given. $text and $button2 are optional arguments and can be
undef.
=back
=head2 GUI::HELPERS::create_label($text, $mode, $wrap, $bold);
=over 1
returns the reference to a new Gtk2::Label. $mode can be "center", "left" or
"right". $wrap and $bold are boolean values.
=back
=head2 GUI::HELPERS::label_to_table($key, $val, $table, $row, $mode, $wrap, $bold);
=over 1
adds a new row to $table. The new row is appended at $row and has two columns:
the first will contain a label with the content of string $k, the second the
content of string $v. $mode, $wrap, $bold are the arguments for
GUI::HELPERS::create_label(), mentioned above.
The function returns the number of the next free row in the table.
=back
=head2 GUI::HELPERS::entry_to_table($text, $var, $table, $row, $visibility, $box);
=over 1
adds a new row to $table. The new row is appended at $row and has two columns:
the first will contain a label with the content of the string $text, the
second one will contain a textentry Gtk2::Entry, associated with the variable
$var. $visibility controls, if the entered text will be displayed or not
(passwords).
The function returns the reference to the new created entry.
=back
=head2 GUI::HELPERS::set_cursor($main, $busy);
=over 1
sets the actual cursor to busy or back to normal. The value of $busy is
boolean.
This functions returns nothing;
=back
=head2 GUI::HELPERS::browse_file($main, $entry, $mode);
=over 1
opens a FileChooser dialog to select files or directories. $entry is a
reference to the variable, where the selected path shall be stored. If $mode
is set to "open", then only files with appropriate suffixes are displyed.
=back
=head2 GUI::HELPERS::set_status($main, $text);
=over 1
sets the text in $text to the statusbar at the bottom of the window.
