Centering horizontally

3 declarations
valuehCenter :: Widget n -> Widget n
#

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

valuehCenterWith :: Maybe Char -> Widget n -> Widget n
#

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).

valuehCenterLayer :: Widget n -> Widget n
#

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

3 declarations
valuevCenterWith :: Maybe Char -> Widget n -> Widget n
#

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).

valuevCenterLayer :: Widget n -> Widget n
#

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

3 declarations
valuecenter :: Widget n -> Widget n
#

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

valuecenterWith :: Maybe Char -> Widget n -> Widget n
#

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).

valuecenterLayer :: Widget n -> Widget n
#

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
