That is the approach taken in this solution. Change the ListView VerticalScrollBar to make it bigger and to make the Inc. Tell the scrollpane to display the ListItems and not to only scroll the pane but the list. One way to do that is to iterate through all of the data and calculate the max length of a field within the data set, then pad all other strings to match that calculation.Īnother approach is to provide a standard width (in characters) for each field, then pad or truncate data to fit this width. There are many possible fixxes on how I could manage this: Make the ListView scrollable like the ScrollPane is and remove the scrollpane. To align data like this in columnar format using strings, you need to calculate a number of additional spaces used to pad each field, then place those padding spaces before or after the data in each field to correctly align the field within the column. Each field will have different lengths of data to be displayed, but must fit within a constant field size. I have provided a sketch below on how I want it to be. But I want to customize the listview so it includes the position and average score aswell. But, the number of spaces required in each field will vary. I am using the listview as an leaderboard and displaying the players name and total score which is done by a string. So if you pass FX containers like HBox it gets simply displayed like the following: HBox hbox new HBox () Label label new Label ('file') ImageView imageView new ImageView ('path to image') hbox. With a mono spaced font, each individual character, including spaces, will have a constant width. when you add a new TreeItem, you can pass alot things to the constructors parameter of TreeItem. Prices, number of reviews and number of nights will have different numbers of digits (and should be right aligned). The host names will have different lengths. I advise you to study a tutorial on TableView usage and consider replacing your solution with a TableView.Įven with a monospaced font, your text won't be aligned. TableViews are also sortable by clicking on column headers, so you don't need the additional combo box for sorting. ![]() Private ObservableList observableList = FXCollections.A TableView is probably a better control for this than a ListView. So you should have public class ListView driversLV Instead, use the initialize() method, which the FXMLLoader will invoke automatically once the fields have been injected. Consequently, of course, they will not be initialized when the constructor is invoked. Make sure the fx:id assigned to the control in the FXML file is the same as the field name.įinally, the FXMLLoader will (by default) create an instance of your controller class by calling its no-argument constructor, then it will initialize the fields. Second, annotate the fields declared in the FXML file with That will allow the FXMLLoader to initialize them even if you declare them private (which you should do). (And the FXMLLoader will not initialize static fields.) The controller is an object associated with the UI loaded from the FXML file, so the fields and methods need to be member of that object, not of the class. Gives: my question is: what is the proper way to initialize ListView? Is my code correct despite this?įirst, don't make anything here static. ![]() Static ObservableList observableList = FXCollections.observableArrayList() Īnd no error then, but ListView is still empty in GUI. ![]() I want it to show some data from xml file, but I have no idea how to properly initialize this ListView. I have my scene made with JavaFX Scene Builder and ListView in it.
