LayoutFrame
Last updated at 11:24 pm UTC on 9 April 2018
A LayoutFrame is specific to a ProportionalLayout of which it is the essential component. A Morph acquires a proportional layout from the message #addMorph:fullFrame: . A layout frame is defined by decimal coordinates in a 1 X 1 rectangle
From the class comment:
I define a frame for positioning some morph in a proportional layout.
Instance variables:
leftFraction
topFraction
rightFraction
bottomFraction (Float) The fractional distance (between 0 and 1) to place the morph in its owner's bounds
leftOffset
topOffset
rightOffset
bottomOffset (Integer) Fixed pixel offset to apply after fractional positioning (e.g., "10 pixel right of the center of the owner")
A LayoutFrame is used with aMorph addMorph: otherMorph fullFrame: aLayoutFrame
and aMorph addMorph: otherMorph frame: aRectangle
(which simply builds a LayoutFrame from aRectangle and delegates to addMorph:fullFrame:)
See also TableLayout for a more table-like way of laying out Morphs.
