我也跟着从这个问题的说明我的应用程序的TableView中设置ComboBoxCell。 (How to put ComboBoxTableCell in a TableView?)集ComboBoxCell在TableView中的JavaFX
细胞的申报工作正常,但下拉框中不会出现在表中。我觉得是这样的,因为只有col1和COL2是在我的模型。 COL3不是写在数据库连接后,我的表项。
我不知道如何takte TableView中组合框,需要你的帮助。
这里是我的代码:
控制器:
package controller;
imports
public class main_controller implements Initializable {
private ObservableList<model> tableData = FXCollections.observableArrayList();
private ObservableList<String> cbValues = FXCollections.observableArrayList("1", "2", "3");
@FXML
private TableView<model> ComboTable;
@FXML
private TableColumn<model, String> col1;
@FXML
private TableColumn<model, String> col2;
@FXML
private TableColumn<model, String> col3;
public main_controller() {
}
@Override
public void initialize(URL location, ResourceBundle resources) {
tableData.clear();
col1.setCellValueFactory(new PropertyValueFactory<model, String>("rCol1"));
col2.setCellValueFactory(new PropertyValueFactory<model, String>("rCol2"));
col3.setCellFactory(ComboBoxTableCell.forTableColumn(new DefaultStringConverter(), cbValues));
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
System.out.println("*** Loaded Oracle-Driver ***");
} catch (ClassNotFoundException e1) {
System.out.println("Driver-Loading failed.");
e1.printStackTrace();
}
try {
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:lukas/[email protected]:1521:OTTO");
Statement statement = conn.createStatement();
ResultSet resultset = statement.executeQuery("SELECT NUMMER, DATEN1, DATEN2 FROM LUKAS order by NUMMER");
String Daten1 = "empty";
String Daten2 = "empty";
// Zum einfügen kann man später auf diese Variable zurückgreifen.
int columnIndex;
System.out.println("*** Connected with Database ***");
while (resultset.next()) {
columnIndex = resultset.getInt("NUMMER");
System.out.println("Tabellenindex der Zeile:\t" + columnIndex);
Daten1 = resultset.getString("DATEN1");
Daten2 = resultset.getString("DATEN2");
System.out.println("Daten1:\t " + Daten1 + "\t\t\tDaten2: " + Daten2);
**model entry = new model(Daten1, Daten2);
tableData.add(entry);**
}
System.out.println("*** Database data saved to Observable List named 'data' ***");
ComboTable.setItems(tableData);
System.out.println("*** Table Items setted ***");
statement.close();
} catch (SQLException e) {
System.out.println("Login fehlgeschlagen.");
e.printStackTrace();
}
}
}
型号:
package model;
import javafx.beans.property.SimpleStringProperty;
public class model {
private final SimpleStringProperty rCol1;
private final SimpleStringProperty rCol2;
public model(String sCol1, String sCol2) {
this.rCol1 = new SimpleStringProperty(sCol1);
this.rCol2 = new SimpleStringProperty(sCol2);
}
public String getRCol1() {
return rCol1.get();
}
public void setRCol1(String set) {
rCol1.set(set);
}
public String getRCol2() {
return rCol2.get();
}
public void setRCol2(String set) {
rCol2.set(set);
}
}
该应用程序看起来像现在这样的权利: Picture
希望你能帮助我!
当您双击单元格中的ComboBoxCell会出现,即进入编辑模式。但首先你需要看到整个图片,你想从combobox分配选定的值。细胞最初会呈现什么等等。 –
谢谢!发布它作为答案,我回答这个问题。 :) – lukas22497
