public void addLayoutComponent(java.lang.String name,
                               java.awt.Component comp)

Adds the specified component with the specified name to the layout.

Specified by:

addLayoutComponent in interface java.awt.LayoutManager

---

removeLayoutComponent

public void removeLayoutComponent(java.awt.Component comp)

Removes the specified component from the layout.

Specified by:

removeLayoutComponent in interface java.awt.LayoutManager

---

preferredLayoutSize

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

Calculates the preferred dimension for the specified panel given the components in the specified parent container.

Specified by:

preferredLayoutSize in interface java.awt.LayoutManager

---

minimumLayoutSize

public java.awt.Dimension minimumLayoutSize(java.awt.Container parent)

Calculates the minimum dimension for the specified panel given the components in the specified parent container.

Specified by:

minimumLayoutSize in interface java.awt.LayoutManager

---

layoutContainer

public void layoutContainer(java.awt.Container parent)

Lays out the container in the specified panel.

Specified by:

layoutContainer in interface java.awt.LayoutManager

---

addLayoutComponent

public void addLayoutComponent(java.awt.Component comp,
                               java.lang.Object constr)

Adds the specified component to the layout, using the specified constraint object.

Specified by:

addLayoutComponent in interface java.awt.LayoutManager2

---

maximumLayoutSize

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

Returns the maximum size of this component.

Specified by:

maximumLayoutSize in interface java.awt.LayoutManager2

---

getLayoutAlignmentX

public float getLayoutAlignmentX(java.awt.Container target)

Returns the alignment along the x axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

Specified by:

getLayoutAlignmentX in interface java.awt.LayoutManager2

---

getLayoutAlignmentY

public float getLayoutAlignmentY(java.awt.Container target)

Returns the alignment along the y axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

Specified by:

getLayoutAlignmentY in interface java.awt.LayoutManager2

---

invalidateLayout

public void invalidateLayout(java.awt.Container target)

Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.

Specified by:

invalidateLayout in interface java.awt.LayoutManager2
