在tornadoFX中是否可以将ListView绑定到ListProperty?
我有一个如下的ViewModel:
class MyVm: ItemViewModel<Item>() {
val stringProperty = bind { item?.myString?.toProperty() }
}
class MyView: View() {
...
init {
with (root) {
label(myVm.stringProperty)
}
}
}
如果项目随vm.item = Item(...)
更改,则stringProperty将相应更新,这将更新所有绑定标签等...
现在我想用ListView做同样的事情:
class MyVm: ItemViewModel<Item>() {
val listProperty = bind { item?.myList?.toProperty() }
}
class MyView: View() {
...
init {
with (root) {
listview {
items = myVm.listProperty
}
}
}
}
但在这种情况下,编译器抱怨listview.items需要ObservableList
而不是ListProperty
答案 0 :(得分:3)
将绑定定义为ListProperty并将listProperty传递给listview构建器:
val listProperty = bind(Item::myList) as ListProperty<YourType>
...
listview(myVm.listProperty)
