Method Detail

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

Parameters:

comp - The component to be added

constraints - The constraints to apply when laying out.

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

Parameters:

name - The name of the component

comp - The component to be added

getHgap

public int getHgap()

Get the horizontal gap between components.

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

getVgap

public int getVgap()

Get the vertical gap between components.

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

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

Parameters:

target - The component which needs to be laid out

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

Parameters:

comp - the component to be removed

setHgap

public void setHgap(int gap)

Set the horizontal gap between components.

Parameters:

gap - The horizontal gap to be set

setVgap

public void setVgap(int gap)

Set the vertical gap between components.

Parameters:

gap - The vertical gap to be set

toString

public java.lang.String toString()

Return a string representation of the layout manager

Overrides:

toString in class java.lang.Object
