getLayoutAlignmentX

float getLayoutAlignmentX(Container target)

Returns the alignment along the x axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

getLayoutAlignmentY

float getLayoutAlignmentY(Container target)

Returns the alignment along the y axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

invalidateLayout

void invalidateLayout(Container target)

Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.
