Class JTCommandButtonLayout  

java.lang.Object
  java.awt.FlowLayout
      com.javathis.utilities.ui.JTCommandButtonLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.io.Serializable

---

public class JTCommandButtonLayout

extends java.awt.FlowLayout

A JTCommandButtonLayout layout is for use with a javax.swing.JPanel that contains the primary command buttons for a frame or dialog, and usually located at the bottom. Examples of the type of buttons considered command buttons would be, OK, CANCEL, APPLY, etc.

It will make al the buttons the same width as the largest button, with consistant gaps, and by default aligns them to the right. This helps managing the command buttons for an application a little easier, and conforms to current standard practices.

Note: All buttons currenly will conform to a height of 27 pixils, a horizontal gap of 5 pixils, and a vertical gap of 5 pixils.

Constructor Detail

JTCommandButtonLayout

public JTCommandButtonLayout()

Creates a JTCommandButtonLayout with a default alignment to the right.

---

JTCommandButtonLayout

public JTCommandButtonLayout(int alignment)

Creates a JTCommandButtonLayout with provided aligment.

Method Detail

resizeComponents

private void resizeComponents()

Method used to resize only AbstractButton objects used in this layout manger.

---

setHgap

public void setHgap(int hgap)

Overridded to prevent changes to the horizontal gap.

---

setVgap

public void setVgap(int vgap)

Overridded to prevent changes to the vertical gap.

---

layoutContainer

public void layoutContainer(java.awt.Container target)

Lays out the container. This method lets each component take its preferred size by reshaping the components in the target container in order to satisfy the constraints of this JTCommandButtonLayout object.

---

preferredLayoutSize

public java.awt.Dimension preferredLayoutSize(java.awt.Container target)

Returns the preferred dimensions for this layout given the visible components in the specified target container.

---

moveComponents

private void moveComponents(java.awt.Container target,
                            int x,
                            int y,
                            int width,
                            int height,
                            int rowStart,
                            int rowEnd,
                            boolean ltr)

Moves the elements in the specified row according to the current alignment.

---

main

public static void main(java.lang.String[] args)

Used for simple testing for this layout.
