[英]JavaFX - Getting KeyCode for Enter Key to execute Event with Text Field to go to entered web address
I have Tried to get the enter key keycode when the enter key is pressed to go to the entered web address. 我试图在按下回车键转到输入的网址时获取回车键密码。 when I try to do that, it gives me an error.
当我尝试这样做时,它给我一个错误。
How can I fix it so it will work? 我该如何修复它才能起作用?
package fxmlstuffs;
import javafx.fxml.Initializable;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.EventHandler;
import javafx.fxml.FXML;
import javafx.scene.control.TextField;
import javafx.scene.web.WebEngine;
import javafx.scene.input.KeyEvent;
public class FXMLDocumentController implements Initializable {
WebEngine web = new WebEngine();
@FXML
private TextField url;
@Override
public void initialize(URL location, ResourceBundle resources) {
assert url != null : "fx:id =\"url\" was not injected: check your FXML file";
url.setOnKeyPressed(new EventHandler<KeyEvent>(){
@Override
public void handle(KeyEvent ke){
int key = ke.getKeyCode();
if(key == KeyEvent.VK_ENTER){
web.load(url.getText());
}
}
});
}
}
The Specific errors straight from Netbeans: 来自Netbeans的特定错误:
Error 1: 错误1:
error: cannot find symbol
int key = ke.getKeyCode();
symbol: method getKeyCode()
location: variable ke of type KeyEvent
Error 2: 错误2:
error: cannot find symbol
if(key == KeyEvent.VK_ENTER){
symbol: variable VK_ENTER
location: class KeyEvent
To elaborate on blaster's answer, it is because you're mixing up the JavaFX and AWT KeyEvent classes. 要详细说明blaster的答案,这是因为您要混合使用JavaFX和AWT KeyEvent类。 You're using
KeyEvent.getKeyCode()
from javafx.scene.input
while the constants KeyEvent.VK_*
are for java.awt.event
您正在使用
javafx.scene.input
KeyEvent.getKeyCode()
,而常数KeyEvent.VK_*
则用于java.awt.event
I get the ENTER-Key like this: 我得到这样的ENTER键:
public class FXMLDocumentController implements Initializable {
WebEngine web = new WebEngine();
@FXML
private TextField url;
@Override
public void initialize(URL location, ResourceBundle resources) {
assert url != null : "fx:id =\"url\" was not injected: check your FXML file";
url.setOnKeyPressed(new EventHandler<KeyEvent>(){
@Override
public void handle(KeyEvent ke){
KeyCode key = ke.getCode();
if(key == KeyCode.ENTER){
web.load(url.getText());
}
}
});
}
}
