[英]JavaFX: move element on window (stage) resize
I have a simple application on JavaFX, it's actually consist of several panes and buttons. 我在JavaFX上有一个简单的应用程序,它实际上由几个窗格和按钮组成。 I can't figure out how to make a button move when the stage resize.
我不知道如何在调整舞台大小时使按钮移动。 So, I want the left bottom button will always be visible even when resize the window.
因此,我希望即使在调整窗口大小时,左下方按钮也始终可见。

here is fxml: 这是fxml:

Your problem is the margins you set on your Buttons
. 您的问题是在
Buttons
上设置的边距。 Follow this layout. 请遵循此布局。 I used
HBox
as the root node. 我使用
HBox
作为根节点。

Add an empty pane into the middle with VGROW set to ALWAYS. 在VGROW设置为ALWAYS的情况下,在中间添加一个空窗格。
Looks like you could achieve the same effect by using a BorderPane
and a VBox
with overlayed background fills and a Region
that always grows inserted between your buttons: 看起来您可以通过使用
BorderPane
和具有覆盖背景填充的VBox
以及始终在按钮之间插入的Region
来实现相同的效果:
