如何从javafx的UI视图中删除按钮的实例 [英] How to delete the instance of the button from UI view in javafx

问题描述

我在UI的HBox中存在一个java fx中的按钮，并且我想在单击同一按钮时删除该按钮.我已经为该事件编写了动作事件:

I have a button in the java fx which is present in HBox of the UI and I want to delete that Button on clicking the same button.i have written the action event for the same:

@FXML
private HBOx projectlist;
String buttonid;

字符串buttoname; /** *初始化控制器类. */ @FXML 公共按钮删除；

String buttoname; /** * Initializes the controller class. */ @FXML public Button delete;

button.setOnMouseClicked(new EventHandler<MouseEvent>() {

        @Override
        public void handle(MouseEvent t) {
            buttonid= button.getId();
            buttoname = button.getText();
            projectlist.getChildren().remove(buttoname);
        }
    });

实际上问题是我正在从该功能的其他控制器获取按钮，尽管我能够在delete动作事件中使用buttonid变量，但我无法在另一个button(Delete)动作事件中使用该按钮:public void setButton(Button button，String buttonname){

Actually the problem is I am getting the button from other controller in this function and i am not able to use that button in another button(Delete) action event although i am able to use buttonid variable in delete action event: public void setButton(Button button,String buttonname) {

projectlist.setSpacing(10);

button.setOnMouseClicked(new EventHandler<MouseEvent>() {

    @Override
    public void handle(MouseEvent t) {
        buttonid= button.getId();
        buttoname = button.getText();


    }
});

projectlist.getChildren().add(button);

projectlist.getChildren().add(button);

}                                                                                                  @FXML
private void gotoDelete(ActionEvent event) throws IOException{
     ProjectModule.DeleteProject(Integer.parseInt(buttonid));

projectlist.getChildren().remove(button);
}                                 

推荐答案

尝试

button.setOnMouseClicked(new EventHandler<MouseEvent>() {

    @Override
    public void handle(MouseEvent t) {
        buttonid= button.getId();
        buttoname = button.getText();

        projectList.getChildren().remove(button);

    }
});
