Give an overview of the available APIs and how you should use them.įirstly, cell editing most commonly requires a different user interface This control supports inline editing of values, and this section attempts to See the Cell class documentation for a more completeĭescription of how to write custom Cells. Generate ListCell instances, which are used to represent an item in the The visuals of the ListView can be entirely customized by replacing theĭefault cell factory. ListView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE) Customizing ListView Visuals Multiple selection in a default ListView instance, it is therefore necessary Property, the default value is SelectionMode.SINGLE. However, as noted in the API documentation for The default SelectionModel used when instantiating a ListView isĪn implementation of the MultipleSelectionModel abstract class.
