Interface Overlayable

All Superinterfaces:

SwingConstants

All Known Implementing Classes:

DefaultOverlayable

public interface Overlayable
extends SwingConstants

Overlayable provides a way to add a number of components on top of another component as the overlay components. Usually we make a component implementing Overlayable interface although it is not required. This interface will allow user to add/remove other components as overlay components and set their location independently.

Field Detail

CLIENT_PROPERTY_OVERLAYABLE

static final String CLIENT_PROPERTY_OVERLAYABLE

Method Detail

addOverlayComponent

void addOverlayComponent(JComponent component)

Adds an overlay component to the center.

Parameters:

component - the overlay component.

addOverlayComponent

void addOverlayComponent(JComponent component,
                         int location)

Adds an overlay component at the specified location. The location could be one of the following values.

• SwingConstants.CENTER
• SwingConstants.SOUTH
• SwingConstants.NORTH
• SwingConstants.WEST
• SwingConstants.EAST
• SwingConstants.NORTH_EAST
• SwingConstants.NORTH_WEST
• SwingConstants.SOUTH_EAST
• SwingConstants.SOUTH_WEST

Parameters:

component - the overlay component.

location - the overlay location.

addOverlayComponent

void addOverlayComponent(JComponent component,
                         int location,
                         int index)

Adds an overlay component at the specified location. The location could be one of the following values.

• SwingConstants.CENTER
• SwingConstants.SOUTH
• SwingConstants.NORTH
• SwingConstants.WEST
• SwingConstants.EAST
• SwingConstants.NORTH_EAST
• SwingConstants.NORTH_WEST
• SwingConstants.SOUTH_EAST
• SwingConstants.SOUTH_WEST

Parameters:

component - the overlay component.

location - the overlay location.

index - the overlay index. 0 means the first overlay component. -1 means the last overlay component.

removeOverlayComponent

void removeOverlayComponent(JComponent component)

Removes an overlay component that was added before.

Parameters:

component -

getOverlayComponents

JComponent[] getOverlayComponents()

Gets the overlay component.

Returns:

the overlay component.

setOverlayLocation

void setOverlayLocation(JComponent component,
                        int location)

Sets the overlay component location. The valid values are defined in SwingConstants. They are

• SwingConstants.CENTER
• SwingConstants.SOUTH
• SwingConstants.NORTH
• SwingConstants.WEST
• SwingConstants.EAST
• SwingConstants.NORTH_EAST
• SwingConstants.NORTH_WEST
• SwingConstants.SOUTH_EAST
• SwingConstants.SOUTH_WEST

Parameters:

location - the overlay component location.

getOverlayLocation

int getOverlayLocation(JComponent component)

Gets the overlay component location. If -1, it means the component doesn't exit.

Returns:

the overlay component location.

getOverlayLocationInsets

Insets getOverlayLocationInsets()

Gets the insets of the overlay component relative to the border of the component. This will affect the actual location of the overlay component except CENTER. If an edge of the insets is greater than 0, it will move the overlay component outwards on that edge. On the opposite, if the value is negative, it will move inward.

Returns:

the insets of the overlay component relative to the border of the component.

setOverlayLocationInsets

void setOverlayLocationInsets(Insets insets)

Sets the insets of the overlay component relative to the border of the component.

Parameters:

insets - the insets of the overlay component relative to the border of the component.

setOverlayVisible

void setOverlayVisible(boolean visible)

Sets all the overlay components visible or invisible. If you want to set one overlay component visible/invisible, you just need to call setVisible of that component.

Parameters:

visible - true to set it visible. False to invisible.
