how to make a modal maximized in tornadofx? - javafx

Question

I need to open the modal maximized .
i tried
class BookingDetailView : Fragment("Booking Details") {
override val root: BorderPane by fxml()
init {
modalStage?.isMaximized = true
}
}
edit:
tried to override onDock()
class BookingDetailView : Fragment("Booking Details") {
override val root: BorderPane by fxml()
override fun onDock() {
//modalStage is null here. when i tried to debug .
**modalStage?.isMaximized = true**
}
}
Invoked from this view :
class FindRoomView : View("Find Room") {
override val root: BorderPane by fxml()
private val dpArrivalDate: JFXDatePicker by fxid()
private val tparrivalTime: JFXTimePicker by fxid()
private val dpDepartureDate: JFXDatePicker by fxid()
private val dpDepartureTime: JFXTimePicker by fxid()
private val btnFindRoom: JFXButton by fxid()
private val cbAdult: JFXComboBox<*> by fxid()
private val cbChildren: JFXComboBox<*> by fxid()
private val btnClear: JFXButton by fxid()
private val btnAdvanceBooking: JFXButton by fxid()
private val btnBookNow: JFXButton by fxid()
val count = FXCollections.observableArrayList<Int>()
// val selections = FXCollections.observableArrayList<AdvanceBookingRoomModel>()
val availability = listOf(RoomType("AC"), RoomType("Non-AC")).observable()
init {
// model.item = this
// model.count.value +=1..50
// (1..50).forEach { i -> model.count.value.add(i) }
// dpArrivalDate.bind(model.arrivalDateProperty)
cbChildren.items = count
cbAdult.items = count
// btnBookNow.setOnAction { bookNow() }
btnBookNow.action { bookNow() }
}
private fun bookNow() {
// openInternalWindow(BookingDetailView::class,owner = root)
find(BookingDetailView::class).openWindow()
}
}
it does'not work.
I also want to have minimize and maximize button on modal.
How to do that?

The modalStage is not yet created when your Fragment is initialized, so modalStage is always null at this point. Override onDock instead and set isMaximized = true there.
You can pass a stageStyle parameter to openModal and openWindow to control available icons in the created Window. Here is a complete application that shows how to access modalStage in onDock:
class ModalApp : App(FindRoomView::class)
class FindRoomView : View("Find Room") {
override val root = stackpane {
button("Book now").action {
find(BookingDetailView::class).openWindow()
}
}
}
class BookingDetailView : Fragment("Booking Details") {
override val root = borderpane()
override fun onDock() {
modalStage?.isMaximized = true
println(modalStage)
}
}
