4. Basic Controls
A more idiomatic way to control the button text would be to use a StringBinding bound to
the textProperty:
togglebutton {
val stateText = selectedProperty().stringBinding {
if (it == true) "ON" else "OFF"
}
textProperty().bind(stateText)
}
Figure 4.11
You can optionally pass a ToggleGroup to the togglebutton() function. This will ensure all
ToggleButton s in that ToggleGroup can only have one in a selected state at a time (Figure
4.12).
import javafx.scene.control.ToggleGroup
import tornadofx.*
class MyView : View() {
private val toggleGroup = ToggleGroup()
}
override val root = hbox {
togglebutton("YES", toggleGroup)
togglebutton("NO", toggleGroup)
togglebutton("MAYBE", toggleGroup)
}

RadioButton
A RadioButton has the same functionality as a ToggleButton but with a different visual
style. When it is selected, it "fills" in a circular control (Figure 4.13).
