DESCRIPTION
This module provides simple utility functions useful for Gnome2/Gtk2
Perl programming.
EXPORT TAGS
:all :main :alter :create
FUNCTIONS BY TAG
:main
process_pending_events ( )
For all pending events, run through the main loop once. Useful for
long processes to update the user interface.
process_main_exit ( [ EXIT_VALUE ] )
This will quit the main event loop after all pending events have
been given a run through the main loop one last time. Once the UI
work is done, exit with the value given or zero. Should the exit
value passed be the string 'no-exit', the function will return TRUE
instead of exiting.
:alter
DOUBLE = force_progress_bounds ( DOUBLE )
Used with Gtk2 progress bars to ensure a given value is within the
0.00 to 1.00 bounds for valid percentages. This function will
modify invalid values appropriately to either 0.00 or 1.00 should
the value be out of bounds.
Gtk2::Label = make_label_wrap_left_centred ( Gtk2::Label )
Given a Gtk2::Label will center the alignment, left justify the
text, make the label selectable and make the label wrap lines.
:create
Gtk2::Button = create_mnemonic_icon_button ( ICON, STRING )
This will create a new Gtk2::Button, a Gtk2::Image and a label then
pack the image and label into an hbox inside the button. The label
is new_with_mnemonic and the ICON given can be one of the following
types: a stock-id string, the path to an image file, a Gtk2::Image
object or a Gtk2::Gdk::Pixbuf object. The button has references to
the three components as follows: $button->{HBOX}, $button->{LABEL}
and $button->{IMAGE}.
