Method Details
-
layoutContainer
Does the actual layout.- Specified by:
layoutContainer
in interfaceLayoutManager
- Parameters:
container
- the container to be laid out
-
addLayoutComponent
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 componentcomponent
- the component to be added
-
minimumLayoutSize
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:
-
preferredLayoutSize
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:
-
removeLayoutComponent
Removes the specified component from our knowledge.- Specified by:
removeLayoutComponent
in interfaceLayoutManager
- Parameters:
component
- the component to be removed
-
addLayoutComponent
Adds the specified component to the layout, using the specified constraint object.- Specified by:
addLayoutComponent
in interfaceLayoutManager2
- Parameters:
comp
- the component to be addedconstraints
- where/how the component is added to the layout.
-
getLayoutAlignmentX
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
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
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
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:
-
resetToPreferredSizes
public void resetToPreferredSizes()Marks the receiver so that the next time this instance is laid out it'll ask for the preferred sizes. -
resetSizeAt
protected void resetSizeAt(int index) Resets the size of the Component at the passed in location.- Parameters:
index
- the index of a component
-
setSizes
protected void setSizes(int[] newSizes) Sets the sizes tonewSizes
.- Parameters:
newSizes
- the new sizes
-
getSizes
protected int[] getSizes()Returns the sizes of the components.- Returns:
- the sizes of the components
-
getPreferredSizeOfComponent

-
getSizeOfComponent
Returns the width of the passed in component.- Parameters:
c
- a component- Returns:
- the width of the component
-
getAvailableSize
-
getInitialLocation
Returns the left inset, unless theInsets
are null in which case 0 is returned.- Parameters:
insets
- the insets- Returns:
- the left inset
-
setComponentToSize
protected void setComponentToSize(Component c, int size, int location, Insets insets, Dimension containerSize) Sets the width of the componentc
to besize
, placing its x location atlocation
