Javafx: Count the number of selected rows in a TableView using bind property

Question

I want to disable a button when the number of selected rows in a tableview is different from 1 using bind property. Is possible? Thanks and sorry for my english

Answer 1

Use Bindings.size on the selectedIndices list of the selection model:

button.disableProperty().bind(Bindings.size(tableView.getSelectionModel().getSelectedIndices())
                                      .isNotEqualTo(1));
