我想使用文本字段來過濾表格視圖,我想要一個文本字段(txtSearch)來搜索'nhs數字','名字','姓氏'和「分類類別」。我已經嘗試過在網上實施各種解決方案,但沒有運氣,我仍然對這一切都很陌生,所以很抱歉,如果這個問題不好。任何幫助將不勝感激,我的代碼如下。Java FX過濾器表格視圖
公共類QueueTabPageController實現Initializable {
@FXML
private TableView<Patient> tableView;
@FXML
private TableColumn<Patient, String> NHSNumberColumn;
@FXML
private TableColumn<Patient, String> firstNameColumn;
@FXML
private TableColumn<Patient, String> lastNameColumn;
@FXML
private TableColumn<Patient, String> timeEnteredColumn;
@FXML
private TableColumn<Patient, String> triageAssessmentColumn;
@FXML
private TextField filterField;
@FXML
private QueueTabPageController queueTabPageController;
private ObservableList<Patient> tableData;
// public static LinkedList<Patient> displayQueue;
/**
* Initializes the controller class. This method is automatically called
* after the fxml file has been loaded.
*
* Initializes the table columns and sets up sorting and filtering.
*/
@Override
public void initialize(URL arg0, ResourceBundle arg1) {
assert tableView != null : "fx:id=\"tableView\" was not injected: check your FXML file 'FXMLQueueTabPage.fxml'";
NHSNumberColumn.setCellValueFactory(new PropertyValueFactory<Patient, String>("nhsNumber"));
firstNameColumn.setCellValueFactory(new PropertyValueFactory<Patient, String>("firstName"));
lastNameColumn.setCellValueFactory(new PropertyValueFactory<Patient, String>("lastName"));
timeEnteredColumn.setCellValueFactory(new PropertyValueFactory<Patient, String>("timeEnteredString"));
triageAssessmentColumn.setCellValueFactory(new PropertyValueFactory<Patient, String>("triage"));
// display the current queue to screen when opening page each time
displayQueue(Queue.queue);
// 0. Initialize the columns.
//firstNameColumn.setCellValueFactory(new PropertyValueFactory<Patient, String>("firstName"));
//lastNameColumn.setCellValueFactory(new PropertyValueFactory<Patient, String>("lastName"));
// 1. Wrap the ObservableList in a FilteredList (initially display all
// data).
FilteredList<Patient> filteredData = new FilteredList<>(tableData,
p -> true);
// 2. Set the filter Predicate whenever the filter changes.
filterField.textProperty().addListener(
(observable, oldValue, newValue) -> {
filteredData.setPredicate(Patient -> {
// If filter text is empty, display all persons.
if (newValue == null || newValue.isEmpty()) {
return true;
}
// Compare first name and last name of every person
// with filter text.
String lowerCaseFilter = newValue.toLowerCase();
if (Patient.getFirstName().toLowerCase()
.contains(lowerCaseFilter)) {
return true; // Filter matches first name.
} else if (Patient.getLastName().toLowerCase()
.contains(lowerCaseFilter)) {
return true; // Filter matches last name.
}
return false; // Does not match.
});
});
// 3. Wrap the FilteredList in a SortedList.
SortedList<Patient> sortedData = new SortedList<>(filteredData);
// 4. Bind the SortedList comparator to the TableView comparator.
sortedData.comparatorProperty().bind(tableView.comparatorProperty());
// 5. Add sorted (and filtered) data to the table.
tableView.setItems(sortedData);
}
我在這裏得到一個錯誤(步驟4):
(TableView.comparatorProperty());
,並說(第5步)
TableView.setItems(sortedData);
: 無法對t中的非靜態方法setItems(ObservableList)進行靜態引用他鍵入的TableView
「我嘗試過在線實施各種解決方案,但沒有運氣。」請顯示你的嘗試,並解釋出了什麼問題。 –
@James_D我主要嘗試這個教程:http://code.makery.ch/blog/javafx-8-tableview-sorting-filtering但是當我在文本字段中輸入時,它從未被解僱。 – Davidaj
該教程中的代碼適合我。 –
