The Alignment widget controls the alignment and size of its child widget. It has four settings: xscale, yscale, xalign, and yalign.
The scale settings are used to specify how much the child widget should expand to fill the space allocated to the Alignment. The values can range from 0 (meaning the child doesn't expand at all) to 1 (meaning the child expands to fill all of the available space).
The align settings are used to place the child widget within the available area. The values range from 0 (top or left) to 1 (bottom or right). Of course, if the scale settings are both set to 1, the alignment settings have no effect.

| :: Float | xalign - the horizontal alignment of the child widget, from 0 (left) to 1 (right). |
| -> Float | yalign - the vertical alignment of the child widget, from 0 (top) to 1 (bottom). |
| -> Float | xscale - the amount that the child widget expands horizontally to fill up unused space, from 0 to 1. A value of 0 indicates that the child widget should never expand. A value of 1 indicates that the child widget will expand to fill all of the space allocated for the Alignment. |
| -> Float | yscale - the amount that the child widget expands vertically to fill up unused space, from 0 to 1. The values are similar to xscale. |
| -> IO Alignment | |
| Creates a new Alignment. | |
| :: AlignmentClass self | |
| => self | |
| -> Float | xalign - the horizontal alignment of the child widget, from 0 (left) to 1 (right). |
| -> Float | yalign - the vertical alignment of the child widget, from 0 (top) to 1 (bottom). |
| -> Float | xscale - the amount that the child widget expands horizontally to fill up unused space, from 0 to 1. A value of 0 indicates that the child widget should never expand. A value of 1 indicates that the child widget will expand to fill all of the space allocated for the Alignment. |
| -> Float | yscale - the amount that the child widget expands vertically to fill up unused space, from 0 to 1. The values are similar to xscale. |
| -> IO () | |
| Sets the Alignment values. | |
| :: AlignmentClass self | |
| => self | |
| -> Int | paddingTop - the padding at the top of the widget |
| -> Int | paddingBottom - the padding at the bottom of the widget |
| -> Int | paddingLeft - the padding at the left of the widget |
| -> Int | paddingRight - the padding at the right of the widget. |
| -> IO () | |
Sets the padding on the different sides of the widget. The padding adds blank space to the sides of the widget. For instance, this can be used to indent the child widget towards the right by adding padding on the left.
| |
| :: AlignmentClass self | |
| => self | |
| -> IO (Int, Int, Int, Int) | (paddingTop, paddingBottom, paddingLeft, paddingRight) - the padding at the top, bottom, left and right of the widget. |
Gets the padding on the different sides of the widget. See alignmentSetPadding.

Horizontal position of child in available space. 0.0 is left aligned, 1.0 is right aligned.
Allowed values: [0,1]
Default value: 0.5
Vertical position of child in available space. 0.0 is top aligned, 1.0 is bottom aligned.
Allowed values: [0,1]
Default value: 0.5
If available horizontal space is bigger than needed for the child, how much of it to use for the child. 0.0 means none, 1.0 means all.
Allowed values: [0,1]
Default value: 1
If available vertical space is bigger than needed for the child, how much of it to use for the child. 0.0 means none, 1.0 means all.
Allowed values: [0,1]
Default value: 1
The padding to insert at the top of the widget.
Allowed values: <= (maxBound :: Int)
Default value: 0
