The FXMLLoader creates an instance of the class specified in the fx:controller attribute of the FXML root element.

You create an instance … Read more
You can manually install the required version of av libraries downloading them from http://www.ubuntuupdates.org/. Search for packages libavutil51, libavformat53, libavcodec53 Download the ones matches the architecture of your JVM and use sudo dpkg -i libav*.deb to install them.
Yes the field name the controller is injected to is always constructed by concatenating the fx:id of the <fx:include> tag with “Controller”. It’s “hidden” in the documentation of the FXMLLoader.CONTROLLER_SUFFIX field. A suffix for controllers of included fxml files. The full key is stored in namespace map. (The namespace map contains all the objects by … Read more
In JavaFX, you cannot change the contents of an ObservableList while a change is already in progress. What is happening here is that your listeners (any of the ones you try) are being fired as part of the box.getSelctionModel().getSelectedItems() ObservableList changing. So basically, you cannot change the selection while a selection change is being processed. … Read more

There are a few different ways to accomplish this, I’ll outline my favourites. Use a ToggleButton and apply a custom style to it. I suggest this because your required control is “like a toggle button” but just looks different from the default toggle button styling. My preferred method is to define a graphic for the … Read more

Create the ObservableList and set the items of the ListView with the ObservableList (listView.setItems(observableList)). 2. Use the setCellFactory() method of the ListView class. You would prefer to use the setCellFactory() method, because this approach simplies the process as well … Read more
