Method Detail

updateTreeEventListener

private void updateTreeEventListener(TreeItem<T> oldRoot,
                                     TreeItem<T> newRoot)

selectAll

public void selectAll()

Convenience method to select all available indices.

Overrides:

selectAll in class MultipleSelectionModelBase<TreeItem<T>>

select

public void select(TreeItem<T> obj)

This method will attempt to select the index that contains the given object. It will iterate through the underlying data model until it finds an item whose value is equal to the given object. At this point it will stop iterating - this means that this method will not select multiple indices.

Overrides:

select in class MultipleSelectionModelBase<TreeItem<T>>

Parameters:

obj - The object to attempt to select in the underlying data model.

clearAndSelect

public void clearAndSelect(int row)

A method that clears any selection prior to setting the selection to the given index. The purpose of this method is to avoid having to call SelectionModel.clearSelection() first, meaning that observers that are listening to the selected index property will not see the selected index being temporarily set to -1.

Overrides:

clearAndSelect in class MultipleSelectionModelBase<TreeItem<T>>

Parameters:

row - The index that should be the only selected index in this selection model.

focus

protected void focus(int itemIndex)

Specified by:

focus in class MultipleSelectionModelBase<TreeItem<T>>

getFocusedIndex

protected int getFocusedIndex()

Specified by:

getFocusedIndex in class MultipleSelectionModelBase<TreeItem<T>>

getItemCount

protected int getItemCount()

Returns the number of items in the data model that underpins the control. An example would be that a ListView selection model would likely return listView.getItems().size(). The valid range of selectable indices is between 0 and whatever is returned by this method.

Specified by:

getItemCount in class MultipleSelectionModelBase<TreeItem<T>>

Returns:

the number of items in the data model that underpins the control

getModelItem

public TreeItem<T> getModelItem(int index)

Returns the item at the given index. An example using ListView would be listView.getItems().get(index).

Specified by:

getModelItem in class MultipleSelectionModelBase<TreeItem<T>>

Parameters:

index - The index of the item that is requested from the underlying data model.

Returns:

Returns null if the index is out of bounds, or an element of type T that is related to the given index.

updateDefaultSelection

private void updateDefaultSelection()
