Thanks. 回答1: You can use an expression binding: disable="${!operater.selectedToggle

问题 actually i'm looking for something very similar to this thread: How to hide the controls of HTMLEditor? so basically i try to add a custom button to the javafx html editor but with the difference that it's implemented through FXML. So my question is: Is there a "work-around" to add custom buttons to the html-editor when it's implemented through FXML? 回答1: Here is some sample code which customizes the HTMLEditor and adds a custom button to it. The sample code does not use fxml but really it's

问题 I'm new to JavaFX and I was wondering what are the best practices in this language to develop a MVC database application, I think my question will be pretty simple if you are an senior developer. Let us consider a simple example of a basic application developed in JavaFX : a ToDoList linked with a SQL Database. The database is just one table Task with an id and a taskDescr VARCHAR field. The purpose is pretty easy : we just want to display the task in a TableView or ListView and be able to

问题 I am trying to build a Next/Previous windows using TabPane . I decided to use TabPane as it is easy to use and design in SceneBuilder . At the start fo the app, I used this to hide the TabBar for now- tabPane.setTabMinHeight(-10); tabPane.setTabMaxHeight(-10); The appearance of the TabPane after this- As you can see, there still remains a small part of TabBar (below the titlebar). How can I hide it completely so that my TabPane will look like just a normal Pane but with all its functionality

问题 I am trying to insert an image in a button using JavaFX CSS. Although, I can do it easily using the "-fx-graphic" tag, I cannot find a way to resize the image in whatever size I want. I can do this through the following FXML code, where I give 30 to my preferred width of image, but I would like to do this with pure CSS. Is there any way to do that? FXML <Button text="Press Me"> <graphic> <ImageView fitWidth="30"> <image> <Image url="myImage.png"/> </image> </ImageView> </graphic> </Button>

问题 I'm a tad confused with JavaFX at the minute. Basically, when I run my code, I can only click on a button on the side bar of the application once, then it will swap the center pane for the one that I want displayed. After that though, it appears that the ActionEvent does not trigger... I've tried reattaching them after handling but it doesn't work, and I have no idea whats wrong. I've spent 2 days trying to crack this, and I'm sure it's something so annoyingly simple. Controller: @FXML
