Field Summary

protected Component[] components


protected int[] sizes


Method Summary

void addLayoutComponent(Component comp, Object constraints)
          Adds the specified component to the layout, using the specified constraint object.

void addLayoutComponent(String place, Component component)
          Adds the component at place.

protected int getAvailableSize(Dimension containerSize, Insets insets)
          Returns the available width based on the container size and Insets.

protected int getInitialLocation(Insets insets)
          Returns the left inset, unless the Insets or null in which case 0 is returned.

float getLayoutAlignmentX(Container target)
          Returns the alignment along the x axis.

float getLayoutAlignmentY(Container target)
          Returns the alignment along the y axis.

protected int getPreferredSizeOfComponent(Component c)
          Returns the width of the passed in Components preferred size.

protected int getSizeOfComponent(Component c)
          Returns the width of the passed in component.

protected int[] getSizes()
          Returns the sizes of the components.

void invalidateLayout(Container c)
          Does nothing.

void layoutContainer(Container container)
          Calculates the actual layout.

Dimension maximumLayoutSize(Container target)
          Returns the maximum layout size, which is Integer.MAX_VALUE in both directions.

Dimension minimumLayoutSize(Container container)
          Returns the minimum size needed to contain the children.

Dimension preferredLayoutSize(Container container)
          Returns the preferred size needed to contain the children.

void removeLayoutComponent(Component component)
          Removes the specified component from our knowledge.

protected void resetSizeAt(int index)
          Resets the size of the Component at the passed in location.

void resetToPreferredSizes()
          Resets the cached sizes so that next time this instance is layed out it'll ask for the preferred sizes.

protected void setComponentToSize(Component c, int size, int location, Insets insets, Dimension containerSize)
          Sets the width of the component c to be size, placing its x location at location, y to the insets.top and height to the containersize.height less the top and bottom insets.

protected void setSizes(int[] newSizes)
          Sets the sizes to newSizes.

protected void updateComponents()
          Determines the components.
