Method Detail

getContentElement

Element getContentElement(ItsNatTree tree,
                        int row,
                        Element nodeParent)

Returns the content element of a tree node.

Default implementation delegates to the default ElementTreeNodeStructure.

Parameters:

tree - the tree component, may be used to provide contextual information. Default implementation ignores it.

row - the tree node row (seeing the tree as a list).

nodeParent - the element containing the tree node markup. Is a hint, if provided should be obtained by calling tree.getItsNatTreeUI().getParentElementFromRow(row).

Returns:

the content element of the tree node.

getHandleElement

Element getHandleElement(ItsNatTree tree,
                       int row,
                       Element nodeParent)

Returns the handle element of a tree node.

Default implementation delegates to the default ElementTreeNodeStructure.

Parameters:

tree - the tree component, may be used to provide contextual information. Default implementation ignores it.

row - the tree node row (seeing the tree as a list).

nodeParent - the element containing the tree node markup. Is a hint, if provided should be obtained by calling tree.getItsNatTreeUI().getParentElementFromRow(row).

Returns:

the handle element of the tree node.

getIconElement

Element getIconElement(ItsNatTree tree,
                     int row,
                     Element nodeParent)

Returns the icon element of a tree node.

Default implementation delegates to the default ElementTreeNodeStructure.

Parameters:

tree - the tree component, may be used to provide contextual information. Default implementation ignores it.

row - the tree node row (seeing the tree as a list).

nodeParent - the element containing the tree node markup. Is a hint, if provided should be obtained by calling tree.getItsNatTreeUI().getParentElementFromRow(row).

Returns:

the icon element of the tree node.

getLabelElement

Element getLabelElement(ItsNatTree tree,
                      int row,
                      Element nodeParent)

Returns the label element of a tree node. This element is used to render and edit the tree node value.

Default implementation delegates to the default ElementTreeNodeStructure.

Parameters:

tree - the tree component, may be used to provide contextual information. Default implementation ignores it.

row - the tree node row (seeing the tree as a list).

nodeParent - the element containing the tree node markup. Is a hint, if provided should be obtained by calling tree.getItsNatTreeUI().getParentElementFromRow(row).

Returns:

the label element of the tree node.

                          int row,
                          Element nodeParent)

Returns the element containing the child tree nodes of the specified tree node.

Default implementation delegates to the default ElementTreeNodeStructure.

Parameters:

tree - the tree component, may be used to provide contextual information. Default implementation ignores it.

row - the tree node row (seeing the tree as a list).

nodeParent - the element containing the tree node markup. Is a hint, if provided should be obtained by calling tree.getItsNatTreeUI().getParentElementFromRow(row).

Returns:

the element containing the child list.
