public class LwActContainer

extends LwPanel

implements LwComposite

This class can be used for creating light weight containers that:

• Wants to have focus.
• Has a special child component that can be selected with rectangle frame if the container has focus (use setAsFocusComponent method to define the child component. The child is called focus indicator component.

This class is a composite component and the child components input events are caught by this class.

Constructor Detail

LwActContainer

public LwActContainer(LwComponent t)

Constructs the container with the specified child component. The child is used to indicate whenever the component has focus.

Parameters:

t - the specified child component.

Method Detail

canHaveFocus

public boolean canHaveFocus()

Description copied from interface: LwComponent

Specifies if the component can have focus.

Specified by:

canHaveFocus in interface LwComponent

Overrides:

canHaveFocus in class LwCanvas

Following copied from interface: org.zaval.lw.LwComponent

Returns:

true if the component can have the focus.

getFocusComponent

public LwComponent getFocusComponent()

Gets the child component that is used to indicate whenever the component has focus.

Returns:

a child focus indicator component.

setAsFocusComponent

public void setAsFocusComponent(int index)

Sets a child focus indicator component by the specified child index. Use -1 value to assign null value to the focus indicator component.

Parameters:

index - the specified child index to be set as the focus indicator.

setRectColor

public void setRectColor(java.awt.Color c)

Sets the specified color to paint rectangle frame around the focus indicator component in case if the container has set focus indicator component.

Parameters:

c - the specified color.

getRectColor

public java.awt.Color getRectColor()

Gets the border color that is used to paint rectangle frame around the focus idicator component.

Returns:

a border color.

catchInput

public boolean catchInput(LwComponent child)

Description copied from interface: LwComposite

Checks if input events for the specified child component should be caught.

Specified by:

catchInput in interface LwComposite

Following copied from interface: org.zaval.lw.LwComposite

Parameters:

child - the specified child component.

Returns:

true if input events for the child component should be caught by this component; false otherwise.

paintOnTop

public void paintOnTop(java.awt.Graphics g)

Description copied from interface: LwContainer

Paints additional elements (for example, marker) after the container and its child components have been rendered.

Specified by:

paintOnTop in interface LwContainer

Overrides:

paintOnTop in class LwPanel

Following copied from interface: org.zaval.lw.LwContainer

Parameters:

g - the graphics context.

remove

public void remove(int i)

Description copied from interface: LwContainer

Removes the component, specified by the index, from this container. The layout manager of this container should be informed by calling componentRemoved method of the manager.

Specified by:

remove in interface LwContainer

Overrides:

remove in class LwPanel

Following copied from interface: org.zaval.lw.LwContainer

Parameters:

index - the index of the component to be removed.

removeAll

public void removeAll()

Description copied from interface: LwContainer

Removes all child components from this container. The layout manager of this container should be informed by calling componentRemoved method of the manager for every child component that has been removed.

Specified by:

removeAll in interface LwContainer

Overrides:

removeAll in class LwPanel

getDefaultLayout

protected LwLayout getDefaultLayout()

Description copied from class: LwPanel

Gets the default layout manager that is set with the container during initialization. This implementation of the method returns LwRastLayout as the default layout manager, the layout manager is got as a static object by "layout.raster" key.

Overrides:

getDefaultLayout in class LwPanel

Following copied from class: org.zaval.lw.LwPanel

Returns:

a layout manager.
