Method Details
-
add
Adds a block to be managed by this instance. This method is usually called by theBlockContainer
, you shouldn't need to call it directly.- Specified by:
add
in interfaceArrangement
- Parameters:
block
- the block.key
- a key that controls the position of the block.
-
arrange
Calculates and sets the bounds of all the items in the specified container, subject to the given constraint. TheGraphics2D
can be used by some items (particularly items containing text) to calculate sizing parameters.- Specified by:
arrange
in interfaceArrangement
- 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.
-
arrangeFN
protected Size2D arrangeFN(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)Arranges the blocks in the container with a fixed width and no height constraint.- Parameters:
container
- the container.g2
- the graphics device.constraint
- the constraint.- Returns:
- The size.
-
arrangeFR
protected Size2D arrangeFR(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)Arranges the blocks in the container with a fixed with and a range constraint on the height.- Parameters:
container
- the container.g2
- the graphics device.constraint
- the constraint.- Returns:
- The size following the arrangement.
-
arrangeFF
protected Size2D arrangeFF(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)Arranges the blocks in the container with the overall height and width specified as fixed constraints.- Parameters:
container
- the container.g2
- the graphics device.constraint
- the constraint.- Returns:
- The size following the arrangement.
-
arrangeRR
protected Size2D arrangeRR(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)Arranges the blocks with the overall width and height to fit within specified ranges.- Parameters:
container
- the container.g2
- the graphics device.constraint
- the constraint.- Returns:
- The size after the arrangement.
-
arrangeRF
protected Size2D arrangeRF(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)Arranges the blocks in the container with a range constraint on the width and a fixed height.- Parameters:
container
- the container.g2
- the graphics device.constraint
- the constraint.- Returns:
- The size following the arrangement.
-
arrangeRN
protected Size2D arrangeRN(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)Arranges the block with a range constraint on the width, and no constraint on the height.- Parameters:
container
- the container.g2
- the graphics device.constraint
- the constraint.- Returns:
- The size following the arrangement.
-
arrangeNN
Arranges the blocks without any constraints. This puts all blocks into a single row.- Parameters:
container
- the container.g2
- the graphics device.- Returns:
- The size after the arrangement.
-
arrangeNF
protected Size2D arrangeNF(BlockContainer container, Graphics2D g2, RectangleConstraint constraint)Arranges the blocks with no width constraint and a fixed height constraint. This puts all blocks into a single row.- Parameters:
container
- the container.g2
- the graphics device.constraint
- the constraint.- Returns:
- The size after the arrangement.
-
