Class PercentLayout

java.lang.Object
se.datadosen.component.buttonbar.PercentLayout
All Implemented Interfaces:
LayoutManager, LayoutManager2
public class PercentLayout extends Object implements LayoutManager2
PercentLayout.
Constraint based layout which allow the space to be splitted using percentages. The following are allowed when adding components to container:
  • container.add(component);
    in this case, the component will be sized to its preferred size
  • container.add(component, "100");
    in this case, the component will have a width (or height) of 100
  • container.add(component, "25%");
    in this case, the component will have a width (or height) of 25 % of the container width (or height)
  • container.add(component, "*");
    in this case, the component will take the remaining space. if several components use the "*" constraint the space will be divided among the components.

      public 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.
      Specified by:
      getLayoutAlignmentY in interface LayoutManager2
