public class Placeholder
A placeholder is a set of Path
-keys, each key stands for a
Dockable
that is currently not visible. Placeholders are not
visible to the user (they have no graphical representation), they
are only used to place Dockable
s at their former position.

Method Summary | ||
---|---|---|
void |
evolve(SplitDockTree.Key key,
boolean checkValidity,
Map<Leaf,Dockable> linksToSet)
Creates or replaces children according to the values found in key . |
|
SplitNode |
getChild(int location)
Gets the child at location . |
|
int |
getChildLocation(SplitNode child)
Gets the location of a child. |
|
Node |
getDividerNode(int x,
int y)
Gets the Node whose divider area contains the point x/y. |
|
Leaf |
getLeaf(Dockable dockable)
Gets the leaf which represents dockable . |
|
int |
getMaxChildrenCount()
Gets the maximal number of children this node can have. |
|
Dimension |
getMinimumSize()
Gets the minimal size of this node. |
|
Dimension |
getPreferredSize()
Gets the preferred size of this node. |
|
PutInfo |
getPut(int x,
int y,
double factorW,
double factorH,
Dockable drop)
Determines where to drop the Dockable drop
if the mouse is at location x/y. |
|
SplitNode |
getVisible()
Gets the root of a subtree such that the root is visible and such that the is the uppermost visible node. |
|
boolean |
insert(SplitDockPathProperty property,
int depth,
Dockable dockable)
If there are elements left in property , then the next node
is to be read and the insert -method of the matching child
to be called.If there are no children, then dockable has to be inserted
as new child.Otherwise this element is to be replaced by a node containing this and the a leaf with dockable .Subclasses may wary this scheme in order to optimize or to find a better place for the dockable . |
|
boolean |
insert(SplitDockPlaceholderProperty property,
Dockable dockable)
Recursively searches for a node or leaf that uses the placeholder specified by property and inserts the dockable there. |
|
boolean |
isInOverrideZone(int x,
int y,
double factorW,
double factorH)
Tells whether the coordinates x/y lie inside the override-zone of the SplitDockStation or not. |
|
boolean |
isOfUse()
Tells whether this node still has any use or can safely be removed from the tree |
|
boolean |
isVisible()
Tells whether this node (or one of this children) contains element that are visible to the user. |
|
void |
setChild(SplitNode child,
int location)
Adds a child to this node at a given location. |
|
|
submit(SplitTreeFactory<N> factory)
Writes the contents of this node into a new tree create by factory . |
|
void |
toString(int tabs,
StringBuilder out)
Writes some contents of this node into out . |
|
void |
visit(SplitNodeVisitor visitor)
Invokes one of the methods of the visitor for every
child in the subtree with this as root. |
