dialog_item-alignment

dialog_item <-> alignment: {column,left,center,right}

Determines how the dialog is fitted in the two-dimensional space of the dialog window by dialog->layout. The values are:

column: Align the item below the upper-neighbour
left: Place the item immediately right of its left-neighbour. (left means flush-left).
center: Place centered items adjacent and centered in the available horizontal space.
right: Flush the item to the right of the available horizontal space.
For example, button objects in OpenWindow dialog windows should be centered. Setting button.alignment to center will properly align buttons for OpenWindow look-and-feel.
