Field Detail

hgap

protected int hgap

horizontal gap

---

vgap

protected int vgap

vertical gap

Constructor Detail

AbstractLayout

public AbstractLayout()

Defaults the horizontal and vertical gaps to 0

---

AbstractLayout

public AbstractLayout(int hgap,
                      int vgap)

Constructor that specifies the horizontal and vertical gaps

Method Detail

getHgap

public int getHgap()

Get the horizontal gap between components.

---

getVgap

public int getVgap()

Get the vertical gap between components.

---

setHgap

public void setHgap(int gap)

Set the horizontal gap between components.

---

setVgap

public void setVgap(int gap)

Set the vertical gap between components.

---

maximumLayoutSize

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

Returns the maximum dimensions for this layout given the component in the specified target container.

Specified by:

maximumLayoutSize in interface java.awt.LayoutManager2

---

getLayoutAlignmentX

public float getLayoutAlignmentX(java.awt.Container parent)

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 parent)

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

---

addLayoutComponent

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

Adds the specified component with the specified name to the layout. By default, we call the more recent addLayoutComponent method with an object constraint argument. The name is passed through directly.

Specified by:

addLayoutComponent in interface java.awt.LayoutManager

---

addLayoutComponent

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

Add the specified component from the layout. By default, we let the Container handle this directly.

Specified by:

addLayoutComponent in interface java.awt.LayoutManager2

---

removeLayoutComponent

public void removeLayoutComponent(java.awt.Component comp)

Removes the specified component from the layout. By default, we let the Container handle this directly.

Specified by:

removeLayoutComponent in interface java.awt.LayoutManager

---

toString

public java.lang.String toString()

Return a string representation of the layout manager
