如何从fxml TextField获取文本 [英] How to get Text from fxml TextField
问题描述
我正在尝试从.fxml文件的firstName和lastName框中获取文本到我的控制器.我不知道如何获取那些firstName和lastName TextFields来将文本传递给控制器,这样我就可以使用它们来创建人员对象
I am trying to get the text from the firstName and lastName box from my .fxml file to my controller. I can't figure out how to get those firstName and lastName TextFields to pass the text through to the controller so i can then use them to create a person object
fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.TextField?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.text.Text?>
<AnchorPane id="AnchorPane" fx:id="createPersonAnchor" prefHeight="247.0" prefWidth="285.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1">
<children>
<Button layoutX="171.0" layoutY="180.0" mnemonicParsing="false" onAction="#cancelCreatePersonAction" prefHeight="37.0" prefWidth="79.0" text="Cancel" />
<TextField id="FirstName" fx:id="firstName" layoutX="115.0" layoutY="28.0" />
<TextField id="LastName" fx:id="lastName" layoutX="115.0" layoutY="78.0" />
<Button layoutX="47.0" layoutY="180.0" mnemonicParsing="false" onAction="#createPersonAction" prefHeight="37.0" prefWidth="79.0" text="Create" />
<Text layoutX="29.0" layoutY="45.0" strokeType="OUTSIDE" strokeWidth="0.0" text="First Name:" wrappingWidth="69.677734375" />
<Text layoutX="29.0" layoutY="95.0" strokeType="OUTSIDE" strokeWidth="0.0" text="Last Name:" wrappingWidth="69.677734375" />
</children>
</AnchorPane>
控制器:
package project1;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.scene.layout.AnchorPane;
/**
* FXML Controller class
*
* @author Fomnus
*/
public class FXMLCreatePersonController implements Initializable {
/**
* Initializes the controller class.
*/
public FXMLCreatePersonController(){
FXMLLoader loader = new FXMLLoader(getClass().getResource("FXMLCreatePerson.fxml"));
loader.setController(this);
try{
loader.load();
}catch(Exception e){
System.out.println(e.getMessage()+ "FXMLCreatePersonController failed");
}
}
@FXML AnchorPane createPersonAnchor;
@FXML public void setFXMLCreatePersonAnchorPane(AnchorPane fxmlCreatePerson){
createPersonAnchor = fxmlCreatePerson;
}
@FXML public AnchorPane getFXMLCreatePersonAnchorPane(){
return createPersonAnchor;
}
@FXML
private void createPersonAction(ActionEvent event) {
}
@FXML
private void cancelCreatePersonAction(ActionEvent event) {
System.out.println("Hello World");
}
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
推荐答案
首先,将控制器设置为FXML
:
First you set a controller to your FXML
:
fx:controller=<Controller.Location>
然后在子目录中,使用Node
旁边的Annotation @FXML进行初始化,并在初始化期间参考其在FXML.file中的ID:
then in your cotroller you use the Annotation @FXML next to the Node
to be initialized refering to its id in the FXML.file during the initialization :
//Example :
@FXML TextField textfield;
最后,为每个要控制的节点设置一个ID(将游戏名称称为Node
:
and finally you set an ID to each Node you want to control (refering to the name you game to the Node
:
fx:id=<idFromController>
并获取文字:
textfield.getText();
