这种情况下的根布局有内容......
object SomeApp extends JFXApp {
stage = new PrimaryStage {
title = "SomeApp"
width = 800
height = 600
val TheButton = new Button("Add a Button") {
onAction = {
e: ActionEvent => {
root.dd(new Button("Some Button"))
}
}
}
val SomeLayout = new AnchorPane {
styleClass += "someStyle"
content = TheButton
}
scene = new Scene {
stylesheets = List(getClass.getResource("Extend.css").toExternalForm)
root = new AnchorPane {
content = SomeLayout
}
}
}
}
我试图让它在单击TheButton时向根布局添加一个按钮...

这有效:
object SFXAddElemAfterStart extends JFXApp {
stage = new PrimaryStage {
title = "SFXAddElemAfterStart"
width = 800
height = 600
scene = new Scene {
val paneNeedingButton = new AnchorPane {
content = layout
}
root = paneNeedingButton
def layout: AnchorPane = new AnchorPane {
styleClass += "someStyle"
content = button
}
def button = new Button("Add a Button") {
onAction = {
e: ActionEvent => {
paneNeedingButton.children += new Button("Some Button")
}
}
}
}
}
}
您只需将按钮放在合理的位置即可。
