问题描述
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.我不知道如何在调整舞台大小时使按钮移动.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.
I have a simple application on JavaFX, it's actually consist of several panes and buttons. I can't figure out how to make a button move when the stage resize. So, I want the left bottom button will always be visible even when resize the window.
这是节点概述:
这是fxml:

推荐答案
看起来您可以通过使用BorderPane
和VBox
以及背景填充物和Region
来实现相同的效果,并且总是在两者之间插入您的按钮:
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:
<?xml version="1.0" encoding="UTF-8"?>
<?import com.jfoenix.controls.JFXButton?>
<?import de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.layout.VBox?>
<?import javafx.scene.layout.Region?>
<BorderPane prefHeight="750.0" prefWidth="1000.0"
xmlns="http://javafx.com/javafx/9.0.4"
xmlns:fx="http://javafx.com/fxml/1">
<left>
<VBox alignment="TOP_LEFT"
spacing="35.0"
style="-fx-background-color: #2b4496, #4059a9; -fx-background-insets: 0, 0 0 0 75;"> <!-- overlay 2 backgrounds produce rectangles -->
<padding>
<Insets right="75.0" />
</padding>
<children>
<JFXButton contentDisplay="GRAPHIC_ONLY" prefWidth="82.0" VBox.vgrow="NEVER">
<graphic>
<FontAwesomeIconView fill="WHITE" glyphName="HOME" size="2em" />
</graphic>
<VBox.margin>
<Insets top="25.0" />
</VBox.margin>
</JFXButton>
<Region VBox.vgrow="ALWAYS" /> <!-- filler -->
<JFXButton contentDisplay="GRAPHIC_ONLY" prefWidth="75.0" VBox.vgrow="NEVER">
<VBox.margin>
<Insets bottom="10.0" />
</VBox.margin>
<graphic>
<FontAwesomeIconView fill="WHITE" glyphName="SIGN_OUT" size="2em" />
</graphic>
</JFXButton>
</children>
</VBox>
</left>
</BorderPane>
