Value Being Set (method used) |
Result When Over-Constrained Horizontally ( x , width , and the east edge are all non-null ) |
---|---|
x or the west edge ( setX or setConstraint ) |
width value is automatically set to east - x . |
width ( setWidth ) |
east edge's value is automatically set to x + width . |
east edge ( setConstraint ) |
x value is automatically set to east - width . |
The rules for the vertical properties are similar:
