Description

This module provides combinators for centering other widgets.

Synopsis

Centering horizontally

hCenter :: Widget n -> Widget n Source #

Center the specified widget horizontally. Consumes all available horizontal space.

hCenterWith :: Maybe Char -> Widget n -> Widget n Source #

Center the specified widget horizontally. Consumes all available horizontal space. Uses the specified character to fill in the space to either side of the centered widget (defaults to space).

hCenterLayer :: Widget n -> Widget n Source #

Center the specified widget horizontally using a Vty image translation. Consumes all available horizontal space. Unlike hCenter, this does not fill the surrounding space so it is suitable for use as a layer. Layers underneath this widget will be visible in regions surrounding the centered widget.

Centering vertically

vCenter :: Widget n -> Widget n Source #

Center a widget vertically. Consumes all vertical space.

vCenterWith :: Maybe Char -> Widget n -> Widget n Source #

Center a widget vertically. Consumes all vertical space. Uses the specified character to fill in the space above and below the centered widget (defaults to space).

vCenterLayer :: Widget n -> Widget n Source #

Center the specified widget vertically using a Vty image translation. Consumes all available vertical space. Unlike vCenter, this does not fill the surrounding space so it is suitable for use as a layer. Layers underneath this widget will be visible in regions surrounding the centered widget.

Centering both horizontally and vertically

center :: Widget n -> Widget n Source #

Center a widget both vertically and horizontally. Consumes all available vertical and horizontal space.

centerWith :: Maybe Char -> Widget n -> Widget n Source #

Center a widget both vertically and horizontally. Consumes all available vertical and horizontal space. Uses the specified character to fill in the space around the centered widget (defaults to space).

centerLayer :: Widget n -> Widget n Source #

Center a widget both vertically and horizontally using a Vty image translation. Consumes all available vertical and horizontal space. Unlike center, this does not fill in the surrounding space with a character so it is usable as a layer. Any widget underneath this one will be visible in the region surrounding the centered widget.

Centering about an arbitrary origin

centerAbout :: Location -> Widget n -> Widget n Source #

Center the widget horizontally and vertically about the specified origin.
