javafx新手切換按鈕事件

<ToggleButton fx:id="toggleDC1" layoutX="52.0" layoutY="146.0" mnemonicParsing="false" onMouseClicked="#loadDC1" selected="false" text="click"> 
    <font> 
    <Font name="Aparajita" size="22.0" fx:id="x1" /> 
    </font> 
</ToggleButton>

我使用JavaFX場景生成器，我想catch事件onMouseClicked或onMouseReleased，但我不明白該怎麼做。這是錯誤，當我點擊切換按鈕：javafx新手切換按鈕事件

誰能舉個例子？在此先感謝

切換按鈕很奇怪。他們進入ToggleGroup，但它們被單獨添加到容器中。

final ToggleGroup tg = new ToggleGroup(); 
final ToggleButton tb1 = new ToggleButton("toggle 1"); 
tb1.setOnAction((ActionEvent e) -> { 
    System.out.println("toggle1"); 
}); 
final ToggleButton tb2 = new ToggleButton("toggle 2"); 
tb2.setOnAction((ActionEvent e) -> { 
    System.out.println("toggle2"); 
}); 
tg.getToggles().addAll(tb1,tb2); 

hbox.getChildren().addAll(tb1,tb2);

我不認爲你應該使用onMouseClicked按鈕。使用鍵盤或觸摸怎麼樣？

我面臨同樣的錯誤以及&能夠解決。

異常在線程「的JavaFX應用程序線程」 java.lang.IllegalArgumentException異常：參數類型不匹配

這裏是你的代碼想怎麼看都像

@FXML 
public void loadDC1(ActionEvent event){ 
    ToggleButton btnSelected = (ToggleButton) event.getSource(); 

    String name=btnSelected.getId().toString(); 

    if(name.equalsIgnoreCase("toggleDC1")){ 
      //do something 
    } 
}

JavaFX中，你需要在您的fxml文件中將所有fx：id，#action定義到控制器類中;

@FXML private ToggleButton toggleDC1; //作爲一類字段

@FXML公共無效loadDC1（ActionEvent的事件）{} //方法
