• Styling FX Buttons with CCS

JavaFX CheckBox

The CheckBox widget provides a selectable checkbox. The checkbox may be in one of three

possible states:

• selected = true – The checkbox is selected

• selected = false – The checkbox is not selected

• indeterminate = true – The checkbox is in an indeterminate state

JavaFX ChoiceBox

The choice box allows the user to pick from one of a set of possible values. The values are shown

in a drop down box. The single value selected is shown in the ChoiceBox area:

A property of the ChoiceBox called "items" contains the items that are available within the

pull-down. A property called "value" contains the currently selected item.

To determine when a value changes, we can use

myChoiceBox.valueProperty().addListener((observable, oldValue, newValue) -> {...});

JavaFX ColorPicker

The ColorPicker component shows a combo-box button that holds the selected color. Clicking this

button produces a pull-down where a color value can be selected.
