Method Detail
layoutContainer
public void layoutContainer(Container container)
Does the actual layout.
- Specified by:
-
layoutContainer
in interfaceLayoutManager
- Parameters:
-
container
- the container to be laid out
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).
- Specified by:
-
addLayoutComponent
in interfaceLayoutManager
- Parameters:
-
place
- the string to be associated with the component -
component
- the component to be added
minimumLayoutSize
public Dimension minimumLayoutSize(Container container)
Returns the minimum size needed to contain the children. The width is the sum of all the children's min widths and the height is the largest of the children's minimum heights.
- Specified by:
-
minimumLayoutSize
in interfaceLayoutManager
- Parameters:
-
container
- the component to be laid out - Returns:
- the minimum dimension for the container
- See Also:
LayoutManager.preferredLayoutSize(java.awt.Container)
preferredLayoutSize
public Dimension preferredLayoutSize(Container container)
Returns the preferred size needed to contain the children. The width is the sum of all the preferred widths of the children and the height is the largest preferred height of the children.
- Specified by:
-
preferredLayoutSize
in interfaceLayoutManager
- Parameters:
-
container
- the container to be laid out - Returns:
- the preferred dimension for the container
- See Also:
LayoutManager.minimumLayoutSize(java.awt.Container)
removeLayoutComponent
public void removeLayoutComponent(Component component)
Removes the specified component from our knowledge.
- Specified by:
-
removeLayoutComponent
in interfaceLayoutManager
- Parameters:
-
component
- the component to be removed
addLayoutComponent
public void addLayoutComponent(Component comp, Object constraints)
Adds the specified component to the layout, using the specified constraint object.
- Specified by:
-
addLayoutComponent
in interfaceLayoutManager2
- Parameters:
-
comp
- the component to be added -
constraints
- where/how the component is added to the layout.
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.
- Specified by:
-
getLayoutAlignmentX
in interfaceLayoutManager2
- Parameters:
-
target
- the target container - Returns:
- the x-axis alignment preference
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.
- Specified by:
-
getLayoutAlignmentY
in interfaceLayoutManager2
- Parameters:
-
target
- the target container - Returns:
- the y-axis alignment preference
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.
- Specified by:
-
invalidateLayout
in interfaceLayoutManager2
- Parameters:
-
c
- the target container
maximumLayoutSize
public Dimension maximumLayoutSize(Container target)
Returns the maximum layout size, which is Integer.MAX_VALUE in both directions.
- Specified by:
-
maximumLayoutSize
in interfaceLayoutManager2
- Parameters:
-
target
- the target container - Returns:
- the maximum size of the container
- See Also:
-
Component.getMaximumSize()
,LayoutManager

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.
