The constraint table can contain the following fields:
- gridx: The 0-based index of the column the child must be placed into
- gridy: The 0-based index of the row the child must be placed into
- gridwidth: The number of column this child will take
- gridheight: The number of row this child will take
- weightx: The horizontal weight of the child. Used to distribute extra space among children
- weighty: The vertical weight of the child. Used to distribute extra space among children
- anchor: Defines where the child should be placed inside its grid space.
Can be Sprite.LAYOUT_ANCHOR_NORTHWEST, Sprite.LAYOUT_ANCHOR_NORTH, Sprite.LAYOUT_ANCHOR_NORTHEAST,
Sprite.LAYOUT_ANCHOR_WEST, Sprite.LAYOUT_ANCHOR_CENTER, Sprite.LAYOUT_ANCHOR_EAST,
Sprite.LAYOUT_ANCHOR_SOUTHWEST, Sprite.LAYOUT_ANCHOR_SOUTH or Sprite.LAYOUT_ANCHOR_SOUTHEAST
- fill: In which directions the child should be expanded to fit the grid space. Can be Sprite.LAYOUT_FILL_NONE, Sprite.LAYOUT_FILL_HORIZONTAL, Sprite.LAYOUT_FILL_VERTICAL or Sprite.LAYOUT_FILL_BOTH
- ipadx: Internal horizontal padding
- ipady: Internal vertical padding
- minWidth: Minimum width
- minHeight: Minimum height
- prefWidth: Preferred width
- prefHeight: Preferred height
- insetTop: the top margin
- insetLeft: the left margin
- insetBottom: the bottom margin
- insetRight: the right margin
Specifying a nil table will clear layout constraints. When a Sprite is resized by the layout system, a Event.LAYOUT_RESIZDE is triggered.
