我创建了一个CustomCB，它是一个用户对象类型的组合框。在我的情况下，我使用<APerson>作为userObject。整个项目和测试器都在这里。第一个是CustomCB，该组件和由此代码生成的JAR文件已添加到库中。这可以在SCENE BUILDER中加载。然后它就可以用于场景设计。
当然，您还有一个测试器CustomCB2，它也可以使用FXML而不是我所做的方式。
实际上，我希望以我在ComboBox中输入的文本开头的项目出现在列表中。但我不知道如何做。因为PERSON类的FIRST NAME或LAST NAME可能以'Pe'开头。如果我找到解决方案，我会在这里发布。
这是自定义组件。
package customCB;
import javafx.beans.property.IntegerProperty;
import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class APerson {
private final StringProperty firstName;
private final StringProperty lastName;
private final IntegerProperty familyID;
private final IntegerProperty personID;
public APerson() {
this(null, null, 0,0);
}
public APerson (String firstName, String lastName, int familyID, int personID) {
this.firstName = new SimpleStringProperty(firstName);
this.lastName = new SimpleStringProperty(lastName);
this.familyID = new SimpleIntegerProperty(familyID);
this.personID = new SimpleIntegerProperty(personID);
}
public int getFamilyID() {
return familyID.get();
}
public void setFamilyID(int FamilyID) {
this.familyID.set(FamilyID);
}
public IntegerProperty familyIDProperty() {
return familyID;
}
public int getPersonID() {
return personID.get();
}
public void setPersonID(int PersonID) {
this.personID.set(PersonID);
}
public IntegerProperty personIDProperty() {
return personID;
}
public String getFirstName() {
return firstName.get();
}
public void setFirstName(String FirstName) {
this.firstName.set(FirstName);
}
public StringProperty firstNameProperty() {
return firstName;
}
public String getLastName() {
return lastName.get();
}
public void setLastName(String LastName) {
this.lastName.set(LastName);
}
public StringProperty lastNameProperty() {
return lastName;
}
public String toString() {
String name = getFirstName() + " " + getLastName()+ " [" + getFamilyID() +"]";
return name;
}
}
这是自定义组件的FXML。
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.ComboBox?>
<?import javafx.scene.layout.VBox?>
<fx:root stylesheets="@application.css" type="javafx.scene.layout.VBox" xmlns="http://javafx.com/javafx/10.0.1" xmlns:fx="http://javafx.com/fxml/1">
<ComboBox fx:id="myCustomCombo" editable="true" onAction="#cbOnAction" prefWidth="300.0" style="-fx-background-color: white;" />
</fx:root>
这是FXML的控制器，但不要在FXML文件中提及它。否则会抛出错误。
package customCB;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
import org.controlsfx.control.textfield.TextFields;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.control.ComboBox;
import javafx.scene.control.ListView;
import javafx.scene.layout.VBox;
public class CustomComboController extends VBox{
@FXML
private ResourceBundle resources;
@FXML
private URL location;
@FXML
private ComboBox<APerson> myCustomCombo;
@FXML
void cbOnAction(ActionEvent event) {
}
@FXML
void initialize() {
assert myCustomCombo != null : "fx:id=\"myCustomCombo\" was not injected: check your FXML file 'CustomLvFXML.fxml'.";
}
public CustomComboController() {
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("customCombo.fxml"));
fxmlLoader.setRoot(this);
fxmlLoader.setController(this);
try {
fxmlLoader.load();
} catch (IOException exception) {
throw new RuntimeException(exception);
}
}
public void setCBValues(javafx.collections.ObservableList<APerson> values) {
myCustomCombo.setItems(values);
myCustomCombo.setEditable(true);
TextFields.bindAutoCompletion(myCustomCombo.getEditor(), myCustomCombo.getItems());
}
}
从网站下载controlsfx-8.40.12.jar，并将其作为库包含在BUILD PATH中。
现在为该项目创建一个jar文件，名为“CustomCB.jar”。
这个JAR文件必须作为定制控件包含在Scene Builder中。我使用的是版本10.0。
既然它已经成为Scene builder的一部分，你就可以在设计中使用这个组件，除非你能像我在测试代码中所做的那样操作。你需要将“CustomCB.jar”作为构建的一部分包含进来。
这是测试者的代码。
package customCB2;
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.VBox;
public class Main extends Application {
static private javafx.collections.ObservableList<APerson> fathers = javafx.collections.FXCollections.observableArrayList();
static private javafx.collections.ObservableList<APerson> mothers = javafx.collections.FXCollections.observableArrayList();
@Override
public void start(Stage stage) throws Exception {
CustomComboController customControl2 = new CustomComboController();
CustomComboController customControl3 = new CustomComboController();
loadFathers();
loadMothers();
customControl2.setCBValues(fathers);
customControl3.setCBValues(mothers);
VBox root = new VBox();
root.getChildren().addAll(customControl2, customControl3);
stage.setScene(new Scene(root));
stage.setTitle("Custom Control Combo box");
stage.setWidth(300);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
private void loadFathers() {
fathers.clear();
fathers.add(new APerson("Hornigold","Arthur",1,63));
fathers.add(new APerson("Andrews","Sundareson",2,60));
fathers.add(new APerson("Christopher","Easweradoss",3,57));
fathers.add(new APerson("Arthur","Kennedy",4,55));
}
private void loadMothers() {
mothers.clear();
mothers.add(new APerson("Victoria","Arthur",1,95));
mothers.add(new APerson("Eliza", "Daniel",1,60));
mothers.add(new APerson("Nesammal", "Rivington",2,57));
mothers.add(new APerson("Ratnammal","Andews",1,55));
}
}
它需要很多改进。如果有人能够改进，请在这里添加。
