Class ComponentBorder

java.lang.Object

kg.apc.jmeter.gui.ComponentBorder

All Implemented Interfaces:

Border

public class ComponentBorder
extends Object
implements Border

The ComponentBorder class allows you to place a real component in the space reserved for painting the Border of a component. This class takes advantage of the knowledge that all Swing components are also Containers. By default the layout manager is null, so we should be able to place a child component anywhere in the parent component. In order to prevent the child component from painting over top of the parent component a Border is added to the parent componet such that the insets of the Border will reserve space for the child component to be painted without affecting the parent component.

public ComponentBorder(JComponent component,
                       ComponentBorder.Edge edge)

Convenience constructor that uses the default alignment (CENTER).

Parameters:

component - the component to be added in the Border area

edge - a valid Edge enum of TOP, LEFT, BOTTOM, RIGHT

ComponentBorder

public ComponentBorder(JComponent component,
                       ComponentBorder.Edge edge,
                       float alignment)

Main constructor to create a ComponentBorder.

Parameters:

component - the component to be added in the Border area

edge - a valid Edge enum of TOP, LEFT, BOTTOM, RIGHT

alignment - the alignment of the component along the specified Edge. Must be in the range 0 - 1.0.

Method Detail

isAdjustInsets

public boolean isAdjustInsets()

setAdjustInsets

public void setAdjustInsets(boolean adjustInsets)

getAlignment

public float getAlignment()

Get the component alignment along the Border Edge

Returns:

the alignment

setAlignment

public final void setAlignment(float alignment)

Set the component alignment along the Border Edge

Parameters:

alignment - a value in the range 0 - 1.0. Standard values would be CENTER (default), LEFT and RIGHT.

getEdge

public ComponentBorder.Edge getEdge()

Get the Edge the component is positioned along

Returns:

the Edge

setEdge

public final void setEdge(ComponentBorder.Edge edge)

Set the Edge the component is positioned along

Parameters:

edge - the Edge the component is position on.

getGap

public int getGap()

Get the gap between the border component and the parent component

Returns:

the gap in pixels.

setGap

public void setGap(int gap)

Set the gap between the border component and the parent component

Parameters:

gap - the gap in pixels (default is 5)

getBorderInsets

public Insets getBorderInsets(Component c)

Specified by:

getBorderInsets in interface Border

isBorderOpaque

public boolean isBorderOpaque()

Specified by:

isBorderOpaque in interface Border

paintBorder

public void paintBorder(Component c,
                        Graphics g,
                        int x,
                        int y,
                        int width,
                        int height)

In this case a real component is to be painted. Setting the location of the component will cause it to be painted at that location.

Specified by:

paintBorder in interface Border

install

public void install(JComponent parent)
