.SH DESCRIPTION
.IX Header "DESCRIPTION"
Utility functions for UI code.
.ie n .SS "button_box_width( $buttons )"
.el .SS "button_box_width( \f(CW$buttons\fP )"
.IX Subsection "button_box_width( $buttons )"
Computes the width required to draw the button box described by the \*(Aqbuttons\*(Aq
parameter. This parameter is a hash reference.
.ie n .SS "button_label( $label, $max_button_width )"
.el .SS "button_label( \f(CW$label\fP, \f(CW$max_button_width\fP )"
.IX Subsection "button_label( $label, $max_button_width )"
Returns a label suitable for a button considering that the maximum
width of the button is \f(CW$max_button_width\fR.
.ie n .SS "layout_buttonbox( $container, $box, [ $padleft ], [ $padright ] )"
.el .SS "layout_buttonbox( \f(CW$container\fP, \f(CW$box\fP, [ \f(CW$padleft\fP ], [ \f(CW$padright\fP ] )"
.IX Subsection "layout_buttonbox( $container, $box, [ $padleft ], [ $padright ] )"
Crops the labels of the Curses::UI::Buttonbox \f(CW$box\fR until it fits in
the \fBcanvaswidth()\fR of the \f(CW$container\fR. \f(CW$padleft\fR and \f(CW$padright\fR can be
used to allow space for padding. The function will set the \*(Aq\-width\*(Aq
and \*(Aq\-x\*(Aq attributes of the Buttonbox. In the worst case, the label
will be reduced to their first letter. The Buttonbox\*(Aqs buttons should
have their \*(Aq\-label\*(Aq attribute set to the full label without any button
decorations (like \*(Aq[\*(Aq), these will be added by the function after
cropping.
