我正在创建一个富UI应用程序,使用FXML在每个部分中都有单独的控制器。我决定遵循这篇教程并将我的FXML用作组件。因此,我使用类作为控制器和组件。一切似乎都正常,但当我尝试将方法放入我的类/控制器时,我遇到了问题。我编辑了我的FXML,所以不直接将控制器放入其中,而是使用类本身。这就是问题所在的地方。
<fx:root fx:id="profilePane" onMouseClicked="#select" onMouseEntered="#hoverOver" onMouseExited="#hoverOut" type="javafx.scene.layout.Pane" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">...etc
每个方法都提示“在根组件上未定义Controller”的错误。我知道我从fxml中删除了那个部分。但是,我按照教程进行操作该怎么办?这是我正在使用的组件类。
imports etc..
public class FxmlProfilePanel extends Pane implements Initializable{
@FXML
private ToggleButton toggleButton;
@FXML
private Pane profilePane;
private FadeTransition fadeTransition=new FadeTransition(Duration.millis(500),toggleButton);
/**
* Initializes the controller class.
*/
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
System.out.println("Is fx thread?:"+Platform.isFxApplicationThread());
}
public FxmlProfilePanel(){
FXMLLoader fxmlLoader=new FXMLLoader(getClass().getResource("/bitcompile/ecps/fxml/FxmlProfilePanel.fxml"));
fxmlLoader.setRoot(this);
fxmlLoader.setController(this);
try {
fxmlLoader.load();
} catch (IOException ex) {
Logger.getLogger(FxmlProfilePanel.class.getName()).log(Level.SEVERE, null, ex);
}
}
public void hoverOver(MouseEvent event){
Platform.runLater(() -> {
if(!toggleButton.isSelected()){
toggleButton.setText("Select profile");
fadeTransition.setFromValue(0);
fadeTransition.setToValue(1.0);
fadeTransition.play();
}else{
toggleButton.setText("Deselect profile");
fadeTransition.setFromValue(0);
fadeTransition.setToValue(1.0);
fadeTransition.play();
}
});
}
public void hoverOut(MouseEvent event){
Platform.runLater(() -> {
if(toggleButton.isSelected())
fadeTransition.setFromValue(1.0);
fadeTransition.setToValue(0);
fadeTransition.play();
});
}
public void selected(MouseEvent event){
if(!toggleButton.isSelected()){
toggleButton.setSelected(true);
toggleButton.setText("Profile Selected");
}else{
toggleButton.setSelected(false);
toggleButton.setText("Select profile");
}
}
}
问题是:当我将fxml/controller作为组件嵌入到另一个fxml中,而这个fxml又嵌套在另一个fxml中时,如何从我的组件类中连接我的方法?(我知道如何遵循普通的fxml样式并使用单独的控制器等来完成所有这些操作,但不是这种方式)我选择了错误的方式吗?应该考虑另一种方法吗?感谢任何见解。
