public interface LayoutManager

Defines the interface for classes that know how to lay outContainers.

Swing's painting architecture assumes the children of aJComponent do not overlap. If aJComponent's LayoutManager allows children to overlap, the JComponent must overrideisOptimizedDrawingEnabled to return false.

Container, JComponent.isOptimizedDrawingEnabled()

  • addLayoutComponent

  If the layout manager uses a per-component string, adds the component comp to the layout, associating it with the string specified by name.
  Parameters:

  comp - the component to be added

  • removeLayoutComponent

  void removeLayoutComponent​(Component comp)
  Removes the specified component from the layout.
  Parameters:
  comp - the component to be removed

  • preferredLayoutSize

  Calculates the preferred size dimensions for the specified container, given the components it contains.
  Parameters:
  parent - the container to be laid out
  Returns:
  the preferred dimension for the container
  See Also:
  minimumLayoutSize(java.awt.Container)

  • minimumLayoutSize

  Calculates the minimum size dimensions for the specified container, given the components it contains.
  Parameters:
  parent - the component to be laid out
  Returns:
  the minimum dimension for the container
  See Also:
  preferredLayoutSize(java.awt.Container)

  • layoutContainer

  void layoutContainer​(Container parent)
  Lays out the specified container.
  Parameters:
  parent - the container to be laid out
