FUNCTIONS BY TAG

32   :main
33       process_pending_events ( )
34           For all pending events, run through the main loop once. Useful for
35           long processes to update the user interface.
36
37       process_main_exit ( [ EXIT_VALUE ] )
38           This will quit the main event loop after all pending events have
39           been given a run through the main loop one last time. Once the UI
40           work is done, exit with the value given or zero. Should the exit
41           value passed be the string 'no-exit', the function will return TRUE
42           instead of exiting.
43
44   :alter
45       DOUBLE = force_progress_bounds ( DOUBLE )
46           Used with Gtk2 progress bars to ensure a given value is within the
47           0.00 to 1.00 bounds for valid percentages. This function will
48           modify invalid values appropriately to either 0.00 or 1.00 should
49           the value be out of bounds.
50
51       Gtk2::Label = make_label_wrap_left_centred ( Gtk2::Label )
52           Given a Gtk2::Label will center the alignment, left justify the
53           text, make the label selectable and make the label wrap lines.
54
55   :create
56       Gtk2::Button = create_mnemonic_icon_button ( ICON, STRING )
57           This will create a new Gtk2::Button, a Gtk2::Image and a label then
58           pack the image and label into an hbox inside the button. The label
59           is new_with_mnemonic and the ICON given can be one of the following
60           types: a stock-id string, the path to an image file, a Gtk2::Image
61           object or a Gtk2::Gdk::Pixbuf object. The button has references to
62           the three components as follows: $button->{HBOX}, $button->{LABEL}
63           and $button->{IMAGE}.
