=head1 SYNOPSYS

B<ugtk3> enables to write GUIes using Gtk+3. It adds nice wrappers on top of
L<Gtk3>, notably gtkpowerpack() and its children gtkpack*()

=head1 Functions

=cut

$border = 5;

sub wm_icon() { $wm_icon || $::Wizard_pix_up || "wiz_default_up.png" }

=head1 Wrappers

Functional-style wrappers to existing Gtk functions; allows to program in
a more functional way, and especially, first, to avoid using temp
variables, and second, to "see" directly in the code the user interface
you're building.

Get attributes (if specified). 4 syntaxes allowed (default values are undef ie. false...) :

the attrs are picked from the default ones (if they exist)

the 'arg' value will tell gtkpowerpack to always read the  attr value directly
