Description |
A widget which controls the alignment and size of its child
|
|
Synopsis |

|
Detail
|
|
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.

Constructors
|
|
|
:: 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.

Methods
|
|
|
:: 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.
- Available since Gtk+ version 2.4

|
:: 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.
- Available since Gtk+ version 2.4
