# Detail

The `Misc` widget is an abstract widget which is not useful itself, but is used to derive subclasses which have alignment and padding attributes.

The horizontal and vertical padding attributes allows extra space to be added around the widget.

The horizontal and vertical alignment attributes enable the widget to be positioned within its allocated area. Note that if the widget is added to a container in such a way that it expands automatically to fill its allocated area, the alignment settings will not alter the widgets position.

# Methods

miscSetAlignment #

Arguments

:: MiscClass self |
=> self |
-> Float | `xalign` - the horizontal alignment, from 0 (left) to 1 (right).
-> Float | `yalign` - the vertical alignment, from 0 (top) to 1 (bottom).
-> IO () |

Sets the alignment of the widget.

miscGetAlignment :: MiscClass self => self -> IO (Double, Double) #

Gets the X and Y alignment of the widget within its allocation. See `miscSetAlignment`.

miscSetPadding #

Arguments

:: MiscClass self |
=> self |
-> Int | `xpad` - the amount of space to add on the left and right of the widget, in pixels.
-> Int | `ypad` - the amount of space to add on the top and bottom of the widget, in pixels.
-> IO () |

Sets the amount of space to add around the widget.

miscGetPadding :: MiscClass self => self -> IO (Int, Int) #

Gets the padding in the X and Y directions of the widget. See `miscSetPadding`.

# Attributes

miscXalign :: MiscClass self => Attr self Float #

The horizontal alignment, from 0 (left) to 1 (right). Reversed for RTL layouts.

Allowed values: [0,1]

Default value: 0.5

miscYalign :: MiscClass self => Attr self Float #

The vertical alignment, from 0 (top) to 1 (bottom).

Allowed values: [0,1]

Default value: 0.5

miscXpad :: MiscClass self => Attr self Int #

The amount of space to add on the left and right of the widget, in pixels.

Allowed values: >= 0

Default value: 0

miscYpad :: MiscClass self => Attr self Int #

The amount of space to add on the top and bottom of the widget, in pixels.

Allowed values: >= 0

Default value: 0
