Method Detail

getTreeApi

Tree getTreeApi()

getLinkedTreerowApi

Treerow getLinkedTreerowApi()

Returns the Treerow that is associated with this treechildren, or null if no such treerow. In other words, it is Treeitem.getTreerowApi() of Component.getParent().

See Also:

Treerow.getLinkedTreechildren()

getItems

java.util.Collection getItems()

Returns a readonly list of all descending Treeitem (children's children and so on).

Note: the performance of the size method of returned collection is no good.

getItemCount

int getItemCount()

Returns the number of child Treeitem including all descendants. The same as getItems().size().

Note: the performance is no good.

getVisibleItemCount

int getVisibleItemCount()

Returns the number of visible descendant Treeitem. Descendants include direct children, gran children and so on.
