addLayoutComponent

public void addLayoutComponent(Component comp,
                               Object constraints)

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

Parameters:

comp - the component to be added

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

addLayoutComponent

public void addLayoutComponent(String place,
                               Component component)

Adds the component at place. Place must be one of JSplitPane.LEFT, RIGHT, TOP, BOTTOM, or null (for the divider).

Parameters:

place

component

getAvailableSize

protected int getAvailableSize(Dimension containerSize,
                               Insets insets)

Returns the available width based on the container size and Insets.

Parameters:

containerSize

insets

getInitialLocation

protected int getInitialLocation(Insets insets)

Returns the left inset, unless the Insets are null in which case 0 is returned.

Parameters:

insets

getLayoutAlignmentX

public float getLayoutAlignmentX(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.

Parameters:

target

getLayoutAlignmentY

public float getLayoutAlignmentY(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.

Parameters:

target

getPreferredSizeOfComponent

protected int getPreferredSizeOfComponent(Component c)

Returns the width of the passed in Components preferred size.

Parameters:

c

getSizeOfComponent

protected int getSizeOfComponent(Component c)

Returns the width of the passed in component.

Parameters:

c

getSizes

protected int[] getSizes()

Returns the sizes of the components.

invalidateLayout

public void invalidateLayout(Container c)

Does nothing. If the developer really wants to change the size of one of the views JSplitPane.resetToPreferredSizes should be messaged.

Parameters:

c

layoutContainer

public void layoutContainer(Container container)

Does the actual layout.

Parameters:

container

maximumLayoutSize

public Dimension maximumLayoutSize(Container target)

Returns the maximum layout size, which is Integer.MAX_VALUE in both directions.

Parameters:

target

minimumLayoutSize

public Dimension minimumLayoutSize(Container container)

Returns the minimum size needed to contain the children. The width is the sum of all the childrens min widths and the height is the largest of the childrens minimum heights.

Parameters:

container

preferredLayoutSize

public Dimension preferredLayoutSize(Container container)

Returns the preferred size needed to contain the children. The width is the sum of all the childrens preferred widths and the height is the largest of the childrens preferred heights.

Parameters:

container

removeLayoutComponent

public void removeLayoutComponent(Component component)

Removes the specified component from our knowledge.

Parameters:

component

resetSizeAt

protected void resetSizeAt(int index)

Resets the size of the Component at the passed in location.

Parameters:

index

resetToPreferredSizes

public void resetToPreferredSizes()

Marks the receiver so that the next time this instance is laid out it'll ask for the preferred sizes.

setComponentToSize

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.

Parameters:

c

size

location

insets

containerSize

setSizes

protected void setSizes(int[] newSizes)

Sets the sizes to newSizes.

Parameters:

newSizes

updateComponents

protected void updateComponents()

Determines the components. This should be called whenever a new instance of this is installed into an existing SplitPane.
