Class BorderLayout

java.lang.Object
  com.jmex.bui.layout.BLayoutManager
      com.jmex.bui.layout.BorderLayout

public class BorderLayout
extends BLayoutManager

Lays out the children of a container around the borders and one in the center. For example:

 +------------------------------------+
 |               NORTH                |
 +-----+------------------------+-----+
 |     |                        |     |
 |  W  |         CENTER         |  E  |
 |     |                        |     |
 +-----+------------------------+-----+
 |               SOUTH                |

Constructor Summary

BorderLayout()
Creates a border layout with zero gap between the horizontal components and zero gap between the vertical.

BorderLayout(int hgap, int vgap)
Creates a border layout with the specified gap between the horizontal components and the specified gap between the vertical.

Method Summary

void	addLayoutComponent(BComponent comp, Object constraints) Components added to a container will result in a call to this method, informing the layout manager of said constraints.
Dimension	computePreferredSize(BContainer target, int whint, int hhint) Computes the preferred size for the supplied container, based on the preferred sizes of its children and the layout policy implemented by this manager.
void	layoutContainer(BContainer target) Effects the layout policy of this manager on the supplied target, adjusting the size and position of its children based on the size and position of the target at the time of this call.
void	removeLayoutComponent(BComponent comp) Components removed to a container for which a layout manager has been configured will result in a call to this method.
void	setGaps(int hgap, int vgap) Configures our inter-component gaps.

Constructor Detail

BorderLayout

public BorderLayout()

Creates a border layout with zero gap between the horizontal components and zero gap between the vertical.

BorderLayout

public BorderLayout(int hgap,
                    int vgap)

Creates a border layout with the specified gap between the horizontal components and the specified gap between the vertical.

Method Detail

setGaps

public void setGaps(int hgap,
                    int vgap)

Configures our inter-component gaps.

addLayoutComponent

public void addLayoutComponent(BComponent comp,
                               Object constraints)

Description copied from class: BLayoutManager

Components added to a container will result in a call to this method, informing the layout manager of said constraints. The default implementation does nothing.

Overrides:

addLayoutComponent in class BLayoutManager

removeLayoutComponent

public void removeLayoutComponent(BComponent comp)

Description copied from class: BLayoutManager

Components removed to a container for which a layout manager has been configured will result in a call to this method. The default implementation does nothing.

Overrides:

removeLayoutComponent in class BLayoutManager

computePreferredSize

public Dimension computePreferredSize(BContainer target,
                                      int whint,
                                      int hhint)

Description copied from class: BLayoutManager

Computes the preferred size for the supplied container, based on the preferred sizes of its children and the layout policy implemented by this manager. Note: it is not necessary to add the container's insets to the returned preferred size.

Specified by:

computePreferredSize in class BLayoutManager

layoutContainer

public void layoutContainer(BContainer target)

Description copied from class: BLayoutManager

Effects the layout policy of this manager on the supplied target, adjusting the size and position of its children based on the size and position of the target at the time of this call. Note: the target's insets must be accounted for when laying out the children.

Specified by:

layoutContainer in class BLayoutManager
