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
Arguments
| :: MiscClass self | |
| => self | |
| -> Float |
|
| -> Float |
|
| -> IO () |
Sets the alignment of the widget.
miscGetAlignment :: MiscClass self => self -> IO (Double, Double)Source
Gets the X and Y alignment of the widget within its allocation. See
miscSetAlignment.
Arguments
| :: MiscClass self | |
| => self | |
| -> Int |
|
| -> Int |
|
| -> IO () |
Sets the amount of space to add around the widget.
miscGetPadding :: MiscClass self => self -> IO (Int, Int)Source
Gets the padding in the X and Y directions of the widget. See
miscSetPadding.
Attributes
miscXalign :: MiscClass self => Attr self FloatSource
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 FloatSource
The vertical alignment, from 0 (top) to 1 (bottom).
Allowed values: [0,1]
Default value: 0.5
