  • Method Details

    • add

      public void add(Block block, Object key)
      Adds a block to be managed by this instance. This method is usually called by the BlockContainer, you shouldn't need to call it directly.
      Specified by:
      add in interface Arrangement
      Parameters:
      block - the block.
      key - a key that controls the position of the block.
    • arrange

      public Size2D arrange(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
      Calculates and sets the bounds of all the items in the specified container, subject to the given constraint. The Graphics2D can be used by some items (particularly items containing text) to calculate sizing parameters.
      Specified by:
      arrange in interface Arrangement
      Parameters:
      container - the container whose items are being arranged.
      g2 - the graphics device.
      constraint - the size constraint.
      Returns:
      The size of the container after arrangement of the contents.
    • arrangeFF

      protected Size2D arrangeFF(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
      Calculates and sets the bounds of all the items in the specified container, subject to the given constraint. The Graphics2D can be used by some items (particularly items containing text) to calculate sizing parameters.
      Parameters:
      container - the container whose items are being arranged.
      g2 - the graphics device.
      constraint - the size constraint.
      Returns:
      The container size after the arrangement.
    • arrangeNF

      protected Size2D arrangeNF(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
      Calculates and sets the bounds of all the items in the specified container, subject to the given constraint. The Graphics2D can be used by some items (particularly items containing text) to calculate sizing parameters.
      Parameters:
      container - the container whose items are being arranged.
      g2 - the graphics device.
      constraint - the size constraint.
      Returns:
      The container size after the arrangement.
    • arrangeRR

      protected Size2D arrangeRR(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
      Arranges a container with range constraints for both the horizontal and vertical.
      Parameters:
      container - the container.
      g2 - the graphics device.
      constraint - the constraint.
      Returns:
      The size of the container.
    • arrangeRF

      protected Size2D arrangeRF(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)
      Arranges the blocks in the container using a fixed height and a range for the width.
      Parameters:
      container - the container.
      g2 - the graphics device.
      constraint - the constraint.
      Returns:
      The size of the container after arrangement.
    • arrangeNN

      protected Size2D arrangeNN(BlockContainer container, Graphics2D g2)
      Arranges the blocks without any constraints. This puts all blocks into a single column.
      Parameters:
      container - the container.
      g2 - the graphics device.
      Returns:
      The size after the arrangement.
    • clear
