NAME

Top

Gtk2::Ex::LayoutBits -- misc Gtk2::Layout helpers

SYNOPSIS

Top

 use Gtk2::Ex::LayoutBits;

FUNCTIONS

Top

Gtk2::Ex::LayoutBits::move_maybe ($layout, $child, $x, $y)

Move $child to $x,$y in $layout as per $layout->move(), if it's not already at $x,$y.

As of Gtk 2.22 $layout->move() or a child_set_property() always does a queue_resize(). This function avoids that if the child is already in the right place.
