# 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`.

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
