Constructor Detail

DBObjectPicker

public DBObjectPicker(boolean showChildren,
                      boolean removeOnShuttle)

Create a picker for selecting DBObjects in a shuttle. The two parameters dictate the behaviour of the picker - whether to remove objects from this picker when they're shuttled, and whether to show the children of a DBObject in the tree.

Method Detail

getNodeMaker

public TreeNodeMaker getNodeMaker()

Returns the class responsible for making the tree nodes in this picker. The object can be customised to change the nodes and children included in the tree.

reloadTree

public void reloadTree()

Reloads the tree model (if elements have been added off-event-queue this will ensure that all is well).

clear

public void clear()

addNode

public void addNode(javax.swing.tree.DefaultMutableTreeNode node)

Adds a node to the top of the list. Use to add custom (non-DBObjects) to the list. Bear in mind only DBObjects are shuttleable.

addDBObjects

public void addDBObjects(DBObject[] objs)

Adds the given DBObjects to the picker (at the top level). Honours the setting of whether to include children or not.

addDBObjectPaths

public void addDBObjectPaths(DBObject[][] paths)

findOrAddChild

protected javax.swing.tree.DefaultMutableTreeNode findOrAddChild(javax.swing.tree.DefaultMutableTreeNode parent,
                                                                 DBObject userObj,
                                                                 java.util.List addToSelection)

Using the given parent node, a child DefaultMutableTreeNode is found or created with the given DBObject as its user object.

setSelectedItems

public void setSelectedItems(DBObject[] objs)

Finds the given objects and adds them to the selection.

isSelectableItemPresent

public boolean isSelectableItemPresent()

Specified by:

isSelectableItemPresent in interface oracle.bali.ewt.shuttle.ItemPicker

Overrides:

isSelectableItemPresent in class AbstractTreePicker

addSelectedItems

public boolean addSelectedItems(java.awt.datatransfer.Transferable[] addMe)

Specified by:

addSelectedItems in interface oracle.bali.ewt.shuttle.ItemPicker

Specified by:

addSelectedItems in class AbstractTreePicker

removeSelectedItems

public void removeSelectedItems()

Removes the selected nodes from their parents - and removes their parents if they are empty.

Specified by:

removeSelectedItems in interface oracle.bali.ewt.shuttle.ItemPicker

Specified by:

removeSelectedItems in class AbstractTreePicker

removeAllSelectableItems

public void removeAllSelectableItems()

Just empties the tree.

Specified by:

removeAllSelectableItems in interface oracle.bali.ewt.shuttle.ItemPicker

Specified by:

removeAllSelectableItems in class AbstractTreePicker

createTransferable

public java.awt.datatransfer.Transferable createTransferable(javax.swing.tree.TreePath treePath)

Specified by:

createTransferable in class AbstractTreePicker

getAllSelectableItems

public java.awt.datatransfer.Transferable[] getAllSelectableItems()

Specified by:

getAllSelectableItems in class AbstractTreePicker

getSelectionDataFlavors

public java.awt.datatransfer.DataFlavor[] getSelectionDataFlavors()

canAcceptFlavors

public boolean canAcceptFlavors(java.awt.datatransfer.DataFlavor[] df)

Specified by:

canAcceptFlavors in interface oracle.bali.ewt.shuttle.ItemPicker

Overrides:

canAcceptFlavors in class AbstractTreePicker

valueChanged

public void valueChanged(javax.swing.event.TreeSelectionEvent e)

Specified by:

valueChanged in interface javax.swing.event.TreeSelectionListener

Overrides:

valueChanged in class AbstractTreePicker
