  use Lire::UI::Utils;

Overview

Utility functions for UI code.

button_box_width( $buttons )

Computes the width required to draw the button box described by the 'buttons' parameter. This parameter is a hash reference.

button_label( $label, $max_button_width )

Returns a label suitable for a button considering that the maximum width of the button is $max_button_width.

layout_buttonbox( $container, $box, [ $padleft ], [ $padright ] )

Crops the labels of the Curses::UI::Buttonbox $box until it fits in the canvaswidth() of the $container. $padleft and $padright can be used to allow space for padding. The function will set the '-width' and '-x' attributes of the Buttonbox. In the worst case, the label will be reduced to their first letter. The Buttonbox's buttons should have their '-label' attribute set to the full label without any button decorations (like '['), these will be added by the function after cropping.
