So you should really have a ListView here, and use a cell factory to configure the text and style of the cells: ListView notificationList =. (The other point is that you are violating the separation of the view (the presentation) from the model (the data).) So if you have a large list, your approach will likely lead to performance issues. The whole point of a ListView is that it only creates nodes for each visible cell, and reuses those cells. If you use a Label or other node class as the data type for your ListView, you create one node for every item in the list. Compare that to your actual data class, Consultation, which probably has a dozen properties or fewer and none of the other overhead. Even then you'd probably find it wouldn't work so well.) GUI node classes are very expensive to create they typically have hundreds of properties and lots of overhead associated with styling and CSS parsing, event listeners, etc etc. Finally, the FXMLLoader will (by default) create an instance of your controller.
A class containing a ListCell implementation that. Make sure the fx:id assigned to the control in the FXML file is the same as the field name. You can find answers, opinions and more information for javafx listview properties. That will allow the FXMLLoader to initialize them even if you declare them private (which you should do). The ListCell is the actual cell that is being displayed for each item in your ListView. Second, annotate the fields declared in the FXML file with FXML. In order to do that, you'll need to implement your own ListCell. What you need to do is add a style to the actual text that is being displayed in the ListView.

The code is written such that only those branches of the scenegraph that might need CSS reapplied are visited. 1 Answer Sorted by: 4 You cannot use HTML to style Strings in JavaFX. Styles are first applied to the parent, then to its children. 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. If you use a Label or other node class as the data type for your ListView, you create one node for every item in the list. (The only exception I can think of is if you were writing a GUI builder, such as Scene Builder, where the data really were the actual GUI nodes. CSS styles are applied to nodes in the JavaFX scenegraph in a way similar to the way CSS styles are applied to elements in the HTML DOM. There are many possible fixxes on how I could manage this: Make the ListView scrollable like the ScrollPane is and remove the scrollpane. Reading over the API, I found that I can do the same thing but this time by overriding the FocusModel using. GuiList.It is basically always an error to use a node subclass (such as Label) as the data type for controls such as ListView, TableView, etc. I have a ListView and am currently overriding the SelectionModel to prevent selection of the items, but when you attempt to select an item, it is still showing the outline. String mySelection = Context.getInstance().getSelected() ĪrrayList selectedList = Context.getInstance().getItemsClicked() Ĭontext.getInstance().setItemsClicked(selectedList)
I know there are many related questions about this but maybe I'm missing something because I can't get the behavior I'm expecting, to work.
