How to right align a button in Java FX toolbar

问题

I am building a UI using Java FX scene builder and I want a button in a toolbar to float towards the right side of the toolbar. I have tried changing the node orientation of the parent(toolbar) and also the button but both seem to be ignored.

回答1:

Add a pane with no content which always grows to fit available space between the left aligned tools in the bar and right aligned ones.

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<ToolBar prefHeight="40.0" prefWidth="318.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8">
   <Button text="Apples" />
   <Button text="Oranges" />
   <Pane HBox.hgrow="ALWAYS" />
   <Button text="Help" />
</ToolBar>

If you could place ur button inside a stack pane then u could make use of Stackpane's alignment property that takes javafx.geometry.Pos - The alignment of the child within the stackpane.For example in ur case:

<StackPane >
<Button translateY="-15" translateX="15"  StackPane.alignment="TOP_RIGHT"/>
</StackPane>

BorderPane mainBorderPane = new BorderPane();     
BorderPane ToolBorderPane = new BorderPane();     
ToolBar tBarLeft=new ToolBar();      
ToolBar tBarRight=new ToolBar();     
ToolBorderPane.setLeft(tBarLeft);      
ToolBorderPane.setRight(tBarRight);      
mainBorderPane.setTop(ToolBorderPane);   

... ... for your left aligment items add tBarLeft and your right aligment items add tBarRight
