Method Detail

getLayoutConstraints

public Object getLayoutConstraints()

Returns layout constraints either as a String or LC depending what was sent in to the constructor or set with setLayoutConstraints(Object).

Returns:

The layout constraints either as a String or LC depending what was sent in to the constructor or set with setLayoutConstraints(Object). Never null.

setLayoutConstraints

public void setLayoutConstraints(Object constr)

Sets the layout constraints for the layout manager instance as a String.

See the class JavaDocs for information on how this string is formatted.

Parameters:

constr - The layout constraints as a String representation. null is converted to "" for storage.

Throws:

RuntimeException - if the constraint was not valid.

getColumnConstraints

public Object getColumnConstraints()

Returns the column layout constraints either as a String or AC.

Returns:

The column constraints either as a String or LC depending what was sent in to the constructor or set with setLayoutConstraints(Object). Never null.

setColumnConstraints

public void setColumnConstraints(Object constr)

Sets the column layout constraints for the layout manager instance as a String.

See the class JavaDocs for information on how this string is formatted.

Parameters:

constr - The column layout constraints as a String representation. null is converted to "" for storage.

Throws:

RuntimeException - if the constraint was not valid.

getRowConstraints

public Object getRowConstraints()

Returns the row layout constraints as a String representation. This string is the exact string as set with setRowConstraints(Object) or sent into the constructor.

See the class JavaDocs for information on how this string is formatted.

Returns:

The row layout constraints as a String representation. Never null.

setRowConstraints

public void setRowConstraints(Object constr)

Sets the row layout constraints for the layout manager instance as a String.

See the class JavaDocs for information on how this string is formatted.

Parameters:

constr - The row layout constraints as a String representation. null is converted to "" for storage.

Throws:

RuntimeException - if the constraint was not valid.

getConstraintMap

public Map<Component,Object> getConstraintMap()

Returns a shallow copy of the constraints map.

Returns:

A shallow copy of the constraints map. Never null.

setConstraintMap

public void setConstraintMap(Map<Component,Object> map)

Sets the constraints map.

Parameters:

map - The map. Will be copied.

getComponentConstraints

public Object getComponentConstraints(Component comp)

Returns the component constraints as a String representation. This string is the exact string as set with setComponentConstraints(java.awt.Component, Object) or set when adding the component to the parent component.

See the class JavaDocs for information on how this string is formatted.

Parameters:

comp - The component to return the constraints for.

Returns:

The component constraints as a String representation or null if the component is not registered with this layout manager. The returned values is either a String or a CC depending on what constraint was sent in when the component was added. May be null.

setComponentConstraints

public void setComponentConstraints(Component comp,
                                    Object constr)

Sets the component constraint for the component that already must be handled by this layout manager.

See the class JavaDocs for information on how this string is formatted.

Parameters:

constr - The component constraints as a String or CC. null is ok.

comp - The component to set the constraints for.

Throws:

RuntimeException - if the constraint was not valid.

IllegalArgumentException - If the component is not handling the component.

isManagingComponent

public boolean isManagingComponent(Component c)

Returns if this layout manager is currently managing this component.

Parameters:

c - The component to check. If null then false will be returned.

Returns:

If this layout manager is currently managing this component.

addLayoutCallback

public void addLayoutCallback(LayoutCallback callback)

Adds the callback function that will be called at different stages of the layout cylce.

Parameters:

callback - The callback. Not null.

removeLayoutCallback

public void removeLayoutCallback(LayoutCallback callback)

Removes the callback if it exists.

Parameters:

callback - The callback. May be null.
