DeckLayout is very similar to the awt CardLayout, except the latter is supposed to have some focus problems. I've not come across these before, and DeckLayout seems to be broken anyway, so I don't use it at all.

DeckLayout treats each component in the container as a card. Only one card is visible at a time, and the container acts like a deck of cards. The ordering of cards is determined by the container's own internal ordering of its component objects. DeckLayout defines a set of methods that allow an application to flip through the cards sequentially, or to show a specified card. The addLayoutComponent method can be used to associate a string identifier with a given card for faster random access.

Method Detail

addLayoutComponent

public void addLayoutComponent(java.awt.Component comp,
                               java.lang.Object constraints)
Adds the specified component to this deck layout's internal table, by name. The object specified by constraints must be a string. The deck layout stores this string as a key-value pair that can be used for random access to a particular card. By calling the show method, an application can display the component with the specified name.

Specified by:
addLayoutComponent in interface java.awt.LayoutManager2
Overrides:
addLayoutComponent in class AbstractLayout

removeLayoutComponent

public void removeLayoutComponent(java.awt.Component comp)
Removes the specified component from the layout.

Specified by:
removeLayoutComponent in interface java.awt.LayoutManager
Overrides:
removeLayoutComponent in class AbstractLayout

preferredLayoutSize

public java.awt.Dimension preferredLayoutSize(java.awt.Container parent)
Calculates the preferred size for the specified panel.

Specified by:
preferredLayoutSize in interface java.awt.LayoutManager

minimumLayoutSize

public java.awt.Dimension minimumLayoutSize(java.awt.Container parent)
Calculates the minimum size for the specified panel.

Specified by:
minimumLayoutSize in interface java.awt.LayoutManager

layoutContainer

public void layoutContainer(java.awt.Container parent)
Lays out the specified container using this deck layout. Each component in the parent container is reshaped to be the same size as the container, minus insets, horizontal and vertical gaps.

Specified by:
layoutContainer in interface java.awt.LayoutManager

checkLayout

private void checkLayout(java.awt.Container parent)
Make sure that the Container really has this layout installed, to avoid serious problems.

setActive

private void setActive(java.awt.Component comp,
                       boolean enabled)
Enable or disable the specified component and all its children. This makes focus traversal function properly. The side effect is that all children are enabled or disabled and specific contexts are not maintained. You can get around this by intercepting setEnabled in your component to restore state if this is important in your context.

first

public void first(java.awt.Container parent)
Flips to the first card of the container.

next

public int next(java.awt.Container parent)
Flips to the next card of the specified container. If the currently visible card is the last one, this method flips to the first card in the layout.

previous

public int previous(java.awt.Container parent)
Flips to the previous card of the specified container. If the currently visible card is the first one, this method flips to the last card in the layout.

last

public void last(java.awt.Container parent)
Flips to the last card of the container.

show

public void show(java.awt.Container parent,
                 java.lang.String name)
Flips to the component that was added to this layout using the specified name. If no such component exists, nothing happens.

show

public void show(java.awt.Container parent,
                 int index)
Flips to the component at the numbered position. If no such component exists, nothing happens.

getComponent

public java.awt.Component getComponent(java.lang.String name)

getName

public java.lang.String getName(java.awt.Container parent,
                                int index)

getIndex

public int getIndex(java.awt.Container parent,
                    java.lang.String name)
