Class BasicSplitPaneUI.BasicHorizontalLayoutManager

protected Component[] components

This array contains the components in the JSplitPane. The left/top component is at index 0, the right/bottom is at 1, and the divider is at 2.

protected int[] sizes

This array contains the current width (for HORIZONTAL_SPLIT) or height (for VERTICAL_SPLIT) of the components. The indices are the same as for components.

public void addLayoutComponent(Component comp,
                               Object constraints)

This method adds the component given to the JSplitPane. The position of the component is given by the constraints object.

Specified by:

addLayoutComponent in interface LayoutManager2

Parameters:

comp - The Component to add.

constraints - The constraints that bind the object.

public void addLayoutComponent(String place,
                               Component component)

This method is called to add a Component to the JSplitPane. The placement string determines where the Component will be placed. The string should be one of LEFT, RIGHT, TOP, BOTTOM or null (signals that the component is the divider).

Specified by:

addLayoutComponent in interface LayoutManager

Parameters:

place - The placement of the Component.

component - The Component to add.

Throws:

IllegalArgumentException - DOCUMENT ME!

protected int getAvailableSize(Dimension containerSize,
                               Insets insets)

This method returns the width of the JSplitPane minus the insets.

Parameters:

containerSize - The Dimensions of the JSplitPane.

insets - The Insets of the JSplitPane.

Returns:

The width of the JSplitPane minus the insets.

protected int getInitialLocation(Insets insets)

This method returns the given insets left value. If the given inset is null, then 0 is returned.

Parameters:

insets - The Insets to use with the JSplitPane.

Returns:

The inset's left value.

public float getLayoutAlignmentX(Container target)

This specifies how a component is aligned with respect to other components in the x fdirection.

Specified by:

getLayoutAlignmentX in interface LayoutManager2

Parameters:

target - The container.

Returns:

The component's alignment.

public float getLayoutAlignmentY(Container target)

This specifies how a component is aligned with respect to other components in the y direction.

Specified by:

getLayoutAlignmentY in interface LayoutManager2

Parameters:

target - The container.

Returns:

The component's alignment.

protected int getPreferredSizeOfComponent(Component c)

This method returns the preferred width of the component.

Parameters:

c - The component to measure.

Returns:

The preferred width of the component.

protected int getSizeOfComponent(Component c)

This method returns the current width of the component.

Parameters:

c - The component to measure.

Returns:

The width of the component.

protected int[] getSizes()

This method returns the sizes array.

Returns:

The sizes array.

public void invalidateLayout(Container c)

This method invalidates the layout. It does nothing.

Specified by:

invalidateLayout in interface LayoutManager2

Parameters:

c - The container to invalidate.

public void layoutContainer(Container container)

This method lays out the components in the container.

Specified by:

layoutContainer in interface LayoutManager

Parameters:

container - The container to lay out.

public Dimension maximumLayoutSize(Container target)

This method returns the maximum size for the container given the components. It returns a new Dimension object that has width and height equal to Integer.MAX_VALUE.

Specified by:

maximumLayoutSize in interface LayoutManager2

Parameters:

target - The container to measure.

Returns:

The maximum size.

public Dimension minimumLayoutSize(Container target)

This method returns the container's minimum size. The minimum width is the sum of all the component's minimum widths. The minimum height is the maximum of all the components' minimum heights.

Specified by:

minimumLayoutSize in interface LayoutManager

Parameters:

target - The container to measure.

Returns:

The minimum size.

public Dimension preferredLayoutSize(Container target)

This method returns the container's preferred size. The preferred width is the sum of all the component's preferred widths. The preferred height is the maximum of all the components' preferred heights.

Specified by:

preferredLayoutSize in interface LayoutManager

Parameters:

target - The container to measure.

Returns:

The preferred size.

public void removeLayoutComponent(Component component)

This method removes the component from the layout.

Specified by:

removeLayoutComponent in interface LayoutManager

Parameters:

component - The component to remove from the layout.

protected void resetSizeAt(int index)

This method resets the size of Component to the preferred size.

Parameters:

index - The index of the component to reset.

public void resetToPreferredSizes()

This method resets the sizes of all the components.

protected void setComponentToSize(Component c,
                                  int size,
                                  int location,
                                  Insets insets,
                                  Dimension containerSize)

This methods sets the bounds of the given component. The width is the size. The height is the container size minus the top and bottom inset. The x coordinate is the location given. The y coordinate is the top inset.

Parameters:

c - The component to set.

size - The width of the component.

location - The x coordinate.

insets - The insets to use.

containerSize - The height of the container.

protected void setSizes(int[] newSizes)

This method stores the given int array as the new sizes array.

Parameters:

newSizes - The array to use as sizes.

protected void updateComponents()

This method determines the size of each component. It should be called when a new Layout Manager is created for an existing JSplitPane.
