public class CoordinateLayout
extends Layout

Allows laying out components based on absolute positions/sizes that are adapted based on available space for the layout. The layout

Constructor Summary

Constructors

Constructor	Description
CoordinateLayout()	Allows creating a coordinate layouts that disables the scaling feature
CoordinateLayout(int width, int height)	This constructor accepts the relative width and height used to define the aspect ratio of the Container
CoordinateLayout(Dimension d)	This constructor accepts the relative width and height used to define the aspect ratio of the Container

Method Summary

Modifier and Type	Method	Description
Dimension	getPreferredSize(Container parent)	Returns the container preferred size
boolean	isOverlapSupported()	This method returns true if the Layout allows Components to Overlap.
void	layoutContainer(Container parent)	Layout the given parent container children

Methods inherited from class Layout

addLayoutComponent, cloneConstraint, equals, getChildrenInTraversalOrder, getComponentConstraint, hashCode, isConstraintTracking, obscuresPotential, overridesTabIndices, removeLayoutComponent, updateTabIndices

Modifier and Type	Method	Description
void	addLayoutComponent(Object value, Component comp, Container c)	Some layouts can optionally track the addition of elements with meta-data that allows the user to "hint" on object positioning.
Object	cloneConstraint(Object constraint)
boolean	equals(Object o)	Indicates whether some other object is "equal to" this one.
protected Component[]	getChildrenInTraversalOrder(Container parent)	Gets the children of the parent container in the order that they should be traversed when tabbing through a form.
Object	getComponentConstraint(Component comp)	Returns the optional component constraint
int	hashCode()	Returns a hash code value for the object.
boolean	isConstraintTracking()	If this method returns true, the addLayoutComponent method will be called when replacing a layout for every component within the container
boolean	obscuresPotential(Container parent)	Some layout managers can obscure their child components in some cases this returns true if the basic underpinnings are in place for that.
boolean	overridesTabIndices(Container parent)	If a layout specifies a different traversal order of its components than the component index, then it should override this method to return true, and it should also override #getChildrenInTraversalOrder(com.codename1.ui.Container) to set the tab indices of a container's children.
void	removeLayoutComponent(Component comp)	Removes the component from the layout this operation is only useful if the layout maintains references to components within it
final int	updateTabIndices(Container parent, int offset)	Updates the tab traversal order

Methods inherited from class Object

clone, getClass, notify, notifyAll, toString, wait, wait, wait

Modifier and Type	Method	Description
protected Object	clone()
final Class	getClass()	Returns the runtime class of an object.
final void	notify()	Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll()	Wakes up all threads that are waiting on this object's monitor.
String	toString()	Returns a string representation of the object.
final void	wait()	Causes current thread to wait until another thread invokes the method or the method for this object.
final void	wait(long timeout)	Causes current thread to wait until either another thread invokes the method or the method for this object, or a specified amount of time has elapsed.
final void	wait(long timeout, int nanos)	Causes current thread to wait until another thread invokes the method or the method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
