Method Detail

addLayoutComponent

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

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

Specified by:

addLayoutComponent in interface java.awt.LayoutManager

Parameters:

name - the name of the component

comp - the component to be added

addLayoutComponent

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

Adds the specified component to the layout, using the specified constraint object.

Specified by:

addLayoutComponent in interface java.awt.LayoutManager2

Parameters:

comp - the component to be added

constraints - where/how the component is added to the layout.

removeLayoutComponent

public void removeLayoutComponent(java.awt.Component comp)

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

Specified by:

removeLayoutComponent in interface java.awt.LayoutManager

Parameters:

comp - the component to remove

See Also:

Container.removeAll()

getHgap

public int getHgap()

Gets the horizontal gap between components.

Returns:

the horizontal gap between components.

See Also:

setHgap

setHgap

public void setHgap(int hgap)

Sets the horizontal gap between components.

Parameters:

hgap - the horizontal gap between components

See Also:

getHgap

getVgap

public int getVgap()

Gets the vertical gap between components.

Returns:

the vertical gap between components.

See Also:

setVgap

setVgap

public void setVgap(int vgap)

Sets the vertical gap between components.

Parameters:

vgap - the vertical gap between components

See Also:

getVgap

getLayoutAlignmentX

public float getLayoutAlignmentX(java.awt.Container target)

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 target)

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

preferredLayoutSize

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

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

Specified by:

preferredLayoutSize in interface java.awt.LayoutManager

Parameters:

target - the component which needs to be laid out

Returns:

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

See Also:

Container, minimumLayoutSize(java.awt.Container), Container.getPreferredSize()

minimumLayoutSize

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

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

Specified by:

minimumLayoutSize in interface java.awt.LayoutManager

Parameters:

target - the component which needs to be laid out

Returns:

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

See Also:

preferredLayoutSize(java.awt.Container), Container, Container.doLayout()

maximumLayoutSize

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

Returns the maximum size of this component.

Specified by:

maximumLayoutSize in interface java.awt.LayoutManager2

See Also:

Component.getMinimumSize(), Component.getPreferredSize(), LayoutManager

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

layoutContainer

public void layoutContainer(java.awt.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 SmartFlowLayout object. This code bears a surprising similarity to FlowLayout

Specified by:

layoutContainer in interface java.awt.LayoutManager

Parameters:

target - the specified component being laid out.

See Also:

Container, Container.doLayout()

getDebug

public void setDebug(boolean b)

Parameters:

b -

debug

protected void debug(java.lang.String out)

getDebugPretext

public java.lang.String getDebugPretext()

Returns:

setDebugPretext
