ComboBox Controls: It is used to present a list of items in a drop-down list. User may select an item from a given list of items. Create a “ComboBox” control using the “ComboBox” class. It is present in the “javafx.scene.control” package. The “ComboBox” class contains a method “setEditable()”. This method contains an argument which takes a “boolean” value. If the user passes “true” in the argument, then the “ComboBox” will be editable. If the user passes “false” in the argument, then the “ComboBox” will be uneditable. Example: The example for “ComboBox” controls is shown below : //create a ComboBox named countryComboBox ComboBox<String> countryComboBox = new ComboBox<>(); //add the fruit items to ComboBox control countryComboBox.getItems().addAll("Africa", "Australia", "India", "China"); From the example “countryComboBox” is a “ComboBox” control and next line code adds the items into a ComboBox control using “getItems().addAll()” method.

If the user passes “false” in the argument, then the “ComboBox” will be uneditable.

Example:

The example for “ComboBox” controls is shown below:

//create a ComboBox named countryComboBox

ComboBox<String> countryComboBox = new ComboBox<>();

//add the fruit items to ComboBox control

countryComboBox.getItems().addAll("Africa", "Australia", "India", "China");
