Method Detail

addLayoutComponent

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

Specified by:

addLayoutComponent in interface java.awt.LayoutManager

addScaledComponent

protected final void addScaledComponent(java.awt.Component comp)

Adds a component to the internal list of scaled components.

Parameters:

comp - Component to add.

removeLayoutComponent

public final void removeLayoutComponent(java.awt.Component comp)

Specified by:

removeLayoutComponent in interface java.awt.LayoutManager

findScaledComponent

protected final ScaledComponent findScaledComponent(java.awt.Component comp)

Returns the corresponding scaled component.

Parameters:

comp - Component to lookup a scaled component for.

Returns:
