Ich habe seit mehreren Tagen damit zu kämpfen, ich habe über Threads, MVC, Bindungen, Schnittstellen und viele interessante Dinge gelesen, aber ich kann sie alle nicht in der richtigen Weise zusammensetzen mach das so.Javafx, wo Labels an StringProperty gebunden werden
Ich möchte nur alle Dateien in mi c aufzulisten: \ und zeigt sie auf eine sich ändernde Label Aber alles, was ich bekommen ist:
Exception in thread "Thread-4" java.lang.IllegalStateException: Not on FX application thread; currentThread = Thread-4
Das ist mein FXML:
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.RowConstraints?>
<GridPane alignment="center" hgap="10" prefHeight="200.0" prefWidth="401.0" vgap="10" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.60" fx:controller="sample.Controller">
<columnConstraints>
<ColumnConstraints />
</columnConstraints>
<rowConstraints>
<RowConstraints />
</rowConstraints>
<children>
<AnchorPane prefHeight="200.0" prefWidth="368.0">
<children>
<Button fx:id="start" layoutX="159.0" layoutY="35.0" mnemonicParsing="false" onAction="#displayFiles" text="Start" />
<Label fx:id="fileLabel" layoutX="20.0" layoutY="100.0" prefHeight="21.0" prefWidth="329.0" text="This label must change on iteration" />
</children>
</AnchorPane>
</children>
</GridPane>
My Main:
import javafx.application.Application;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
primaryStage.setTitle("Dummy App");
primaryStage.setScene(new Scene(root));
primaryStage.setResizable(false);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
My C ontroller:
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
public class Controller {
@FXML
Button start;
@FXML
Label fileLabel;
@FXML
void displayFiles(ActionEvent event) throws Exception{
Model model = new Model();
//BINDING
fileLabel.textProperty().bind(model.status);
Thread thread = new Thread(model);
thread.start();
}
}
Und das Modell:
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import java.io.File;
/**
* Created by R00715649 on 16-Nov-16.
*/
public class Model implements Runnable {
File rootDirectory = new File("C:/");
StringProperty status = new SimpleStringProperty("Starting scan...");
@Override
public void run() {
try{
File[] fileList = rootDirectory.listFiles();
for (File f:fileList){
processDirectory(f);
}
}catch (Exception e){
}
}
void processDirectory (File directory){
if (directory.isDirectory()){
File[] fileList = directory.listFiles();
for (File f:fileList){
processDirectory(f);
}
}else{
System.out.println(directory.getAbsolutePath());
status.set(directory.getAbsolutePath());
}
}
}
