Method Detail

addLayoutComponent

public final void addLayoutComponent(String name,
                                     Component comp)

Specified by:

addLayoutComponent in interface LayoutManager

addScaledComponent

protected final void addScaledComponent(Component comp)

Adds a component to the internal list of scaled components.

Parameters:

comp - Component to add.

removeLayoutComponent

public final void removeLayoutComponent(Component comp)

Specified by:

removeLayoutComponent in interface LayoutManager

findScaledComponent

protected final ScaledComponent findScaledComponent(Component comp)

Returns the corresponding scaled component.

Parameters:

comp - Component to lookup a scaled component for.

Returns:

Scaled component or null if not found.

public final Dimension preferredLayoutSize(Container container)

Specified by:

preferredLayoutSize in interface LayoutManager

minimumLayoutSize

public final Dimension minimumLayoutSize(Container container)

Specified by:

minimumLayoutSize in interface LayoutManager

getFactor

public final double getFactor()

Returns the current scaling factor.

Returns:
