Class CardLayout2

java.lang.Object

java.awt.CardLayout

org.nuiton.jaxx.runtime.swing.CardLayout2

All Implemented Interfaces:

LayoutManager, LayoutManager2, Serializable

Direct Known Subclasses:

CardLayout2Ext

public class CardLayout2
extends CardLayout

An override of the awt CardLayout. Because in the original layout is not overridable : everything is package level accessible. This new class offers to test if a constrains (as a Serializable) is actually dealed by the layout, via the method contains(Serializable). We had also another method to obtain the current visible component in a container layouted by the class, via the method getVisibleComponent(Container).

list of already loaded context (since the CardLayout.vector attribute is package visible...

useOnlyVisibleComponentDimension

protected boolean useOnlyVisibleComponentDimension

A flag to compute dimension only on visible component. This is usefull when we only care of the visible component.

Method Detail

addLayoutComponent

public void addLayoutComponent(Component comp,
                               Object constraints)

Specified by:

addLayoutComponent in interface LayoutManager2

Overrides:

addLayoutComponent in class CardLayout

removeLayoutComponent

public void removeLayoutComponent(Component comp,
                                  Serializable constraints)

contains

public boolean contains(Serializable constraints)

Test if a constrains is contained in the layout.

Parameters:

constraints - l'identifiant a tester

Returns:

true si l'identifiant est deja present dans le layout, false otherwise.

getVisibleComponent

public Component getVisibleComponent(Container container)

Obtain the visible component in the container.

Parameters:

container - the container using this layout

Returns:

the component visible in the container.

getComponent

public Component getComponent(Container container,
                              String constraints)

preferredLayoutSize

public Dimension preferredLayoutSize(Container parent)

Determines the preferred size of the container argument using this card layout.

Specified by:

preferredLayoutSize in interface LayoutManager

Overrides:

preferredLayoutSize in class CardLayout

Parameters:

parent - the parent container in which to do the layout

Returns:

the preferred dimensions to lay out the subcomponents of the specified container

See Also:

Container.getPreferredSize(), CardLayout.minimumLayoutSize(java.awt.Container)

minimumLayoutSize

public Dimension minimumLayoutSize(Container parent)

Calculates the minimum size for the specified panel.

Specified by:

minimumLayoutSize in interface LayoutManager

Overrides:

minimumLayoutSize in class CardLayout

Parameters:

parent - the parent container in which to do the layout

Returns:

the minimum dimensions required to lay out the subcomponents of the specified container

See Also:

Container.doLayout(), CardLayout.preferredLayoutSize(java.awt.Container)

maximumLayoutSize

public Dimension maximumLayoutSize(Container target)

Returns the maximum dimensions for this layout given the components in the specified target container.

Specified by:

maximumLayoutSize in interface LayoutManager2

Overrides:

maximumLayoutSize in class CardLayout

Parameters:

target - the component which needs to be laid out

See Also:

Container, minimumLayoutSize(java.awt.Container), preferredLayoutSize(java.awt.Container)

layoutContainer

public void layoutContainer(Container parent)

Lays out the specified container using this card layout. Each component in the parent container is reshaped to be the size of the container, minus space for surrounding insets, horizontal gaps, and vertical gaps.

Specified by:

layoutContainer in interface LayoutManager

Overrides:

layoutContainer in class CardLayout

Parameters:

parent - the parent container in which to do the layout

Container.doLayout()

isUseOnlyVisibleComponentDimension

public boolean isUseOnlyVisibleComponentDimension()

setUseOnlyVisibleComponentDimension

public void setUseOnlyVisibleComponentDimension(boolean useOnlyVisibleComponentDimension)

reset

public void reset(Container parent)

remove from cardlayout and linked container all his components.

Parameters:

parent - the parent container linked with the layout

checkContainer

protected void checkContainer(Container container)

checkConstraints

protected void checkConstraints(String constraints)

getContexts

public Serializable[] getContexts()
