Method Detail

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.

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>>

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.
