如何在 tornadofx 中最大化模態？

Question

我需要打開模態最大化。 我試過

class BookingDetailView : Fragment("Booking Details") {
    override val root: BorderPane by fxml()
    init {
        modalStage?.isMaximized = true
    } 
}

編輯：試圖覆蓋 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**

}

}

從這個視圖調用：

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()
}
}

這是行不通的。 我還想在模態上最小化和最大化按鈕。 怎么做？

初始化 Fragment 時， modalStage尚未創建，因此modalStage始終為 null。 改寫onDock並在那里設置isMaximized = true 。

您可以將stageStyle參數傳遞給openModal和openWindow以控制創建的 Window 中的可用圖標。 這是一個完整的應用程序，展示了如何在modalStage中訪問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)
    }
}
