Constructor Detail

ColumnFlowLayout

public ColumnFlowLayout()

Constructs a new Flow Layout with a centered alignment and a default 5-unit horizontal and vertical gap.

ColumnFlowLayout

public ColumnFlowLayout(int hgap,
                        int vgap)

Creates a new flow layout manager with the indicated alignment and the indicated horizontal and vertical gaps.

The value of the alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, or FlowLayout.CENTER.

Parameters:

hgap - the horizontal gap between components.

vgap - the vertical gap between components.

Method Detail

getHgap

public int getHgap()

Gets the horizontal gap between components.

Returns:

the horizontal gap between components.

setHgap

public void setHgap(int hgap)

Sets the horizontal gap between components.

Parameters:

hgap - the horizontal gap between components

getVgap

public int getVgap()

Gets the vertical gap between components.

Returns:

the vertical gap between components.

setVgap

public void setVgap(int vgap)

Sets the vertical gap between components.

Parameters:

vgap - the vertical gap between components

addLayoutComponent

public void addLayoutComponent(String name,
                               Component comp)

Adds the specified component to the layout. Not used by this class.

Specified by:

addLayoutComponent in interface LayoutManager

Parameters:

name - the name of the component

comp - the component to be added

removeLayoutComponent

public void removeLayoutComponent(Component comp)

Removes the specified component from the layout. Not used by this class.

Specified by:

removeLayoutComponent in interface LayoutManager

Parameters:

comp - the component to remove

preferredLayoutSize

public Dimension preferredLayoutSize(Container target)

Returns the preferred dimensions for this layout given the components in the specified target container.

Specified by:

preferredLayoutSize in interface LayoutManager

Parameters:

target - the component which needs to be laid out

Returns:

the preferred dimensions to lay out the subcomponents of the specified container.

minimumLayoutSize

public Dimension minimumLayoutSize(Container target)

Returns the minimum dimensions needed to layout the components contained in the specified target container.

Specified by:

minimumLayoutSize in interface LayoutManager

Parameters:

target - the component which needs to be laid out

Returns:

the minimum dimensions to lay out the subcomponents of the specified container.

layoutContainer

public void layoutContainer(Container target)

Lays out the container. This method lets each component take its preferred size by reshaping the components in the target container in order to satisfy the constraints of this ColumnFlowLayout object.

Specified by:

layoutContainer in interface LayoutManager

Parameters:

target - the specified component being laid out.

toString

public String toString()

Returns a string representation of this FlowLayout object and its values.

Overrides:
