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.
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>
(Verified in Scene Builder 11.0.0)
One option: Use two ToolBar containers wrapped with an HBox container. Put the Help button in the right ToolBar. Put the left-aligned buttons in the left toolbar. For the left ToolBar, set the HGrow to ALWAYS. For the Right ToolBar, set HGrow to NEVER. For each ToolBar, set all Sizes to USE_COMPUTED_SIZE.
Here is the relevant fxml:
<HBox VBox.vgrow="NEVER">
<children>
<ToolBar HBox.hgrow="ALWAYS">
<items>
<Button text="Apples" />
<Button text="Oranges" />
</items>
</ToolBar>
<ToolBar HBox.hgrow="NEVER">
<items>
<Button text="Help" />
</items>
</ToolBar>
</children>
</HBox>
This is the hierarchy as displayed in Scene Builder:
This is the display within Scene Builder:
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
It can be done with some hack: apply 180 degree rotation around Y-axis for the toolbar and all its buttons.
<ToolBar rotate="-180.0" HBox.hgrow="ALWAYS">
<items>
<Button mnemonicParsing="false" rotate="180.0" text="Button">
<rotationAxis>
<Point3D y="1.0" />
</rotationAxis>
</Button>
</items>
<rotationAxis>
<Point3D y="1.0" />
</rotationAxis>
</ToolBar>

I'm using Scene Builder (v11.0.0) to create FXML files for scenes in JavaFX (v12) but, despite instructing all containers to USE_COMPUTED_SIZE for the preferred widths and heights, the rendered scenes (as seen in Scene Builder and also when run as a JavaFX application which loads those FXML files) are being clipped at the right and bottom edges so that bits of nodes are chopped off.
And in Scene Builder it seems that the renderer must know that the scene won't fit the allowed bounds because the editor shows blue boundary markers which are clearly some way beyond the rendered rectangle.
View in Scene Builder
The view in Scene Builder shows that more space is needed at the bottom in order to give the buttons sufficient space (their bottom edge, and the lower edge of the TitledPane is missing). And more space is needed at the right in order to fit the right edges of the DatePicker and TitledPane. The blue boundary markers show clearly where the actual content ends, so it's not clear why the display area is being calculated to be several pixels shorter than this.
View of running Java application
Once the FXML files are used to populate a window in a JavaFX application, the same thing is seen: the calculated size for the window is a number of pixels too few to fit the whole scene correctly.
If the blue boundary markers have correctly been calculated to show that extra display area width and height are needed, how do I tell the FXML to require this additional space when rendering?
Is this a known bug/limitation in Scene Builder, FXML, or JavaFX. Or is there something more I need to do beyond just selecting USE_COMPUTED_SIZE for the preferred dimensions?
In order to make this explicit, see the example FXML below which displays the problem illustrated.

This does appear to be a bug in JavaFX, specifically DatePicker, as this simple example can reproduce the problem:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.DatePicker;
import javafx.scene.layout.Region;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
VBox root = new VBox(new DatePicker());
// Problem shows up when using USE_COMPUTED_SIZE (the default) as well
root.setMinSize(Region.USE_PREF_SIZE, Region.USE_PREF_SIZE);
root.setMaxSize(Region.USE_PREF_SIZE, Region.USE_PREF_SIZE);
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
}
Resulting in:
Note: It does not seem to matter what parent the DatePicker is put in. Nor does the problem appear with other controls.
A workaround to this issue appears to be calling Window.sizeToScene() after calling show(). I don't understand why that would make a difference, but it does. Unfortunately, this will only help in the real application, not in Scene Builder.
I got a SegmentedButton which contains 3 "glyph only" ToggleButtons like this:
<SegmentedButton maxWidth="Infinity" prefWidth="Infinity">
<buttons>
<fx:define>
<ToggleGroup fx:id="albumViewToggleGroup"/>
</fx:define>
<ToggleButton maxWidth="Infinity" fx:id="tagCloudToggle" mnemonicParsing="false" selected="true" toggleGroup="$albumViewToggleGroup">
<graphic>
<Glyph fontFamily="FontAwesome" icon="TAGS"></Glyph>
</graphic>
</ToggleButton>
<ToggleButton maxWidth="Infinity" fx:id="gridFlowToggle" mnemonicParsing="false" toggleGroup="$albumViewToggleGroup" >
<graphic>
<Glyph fontFamily="FontAwesome" icon="TH"></Glyph>
</graphic>
</ToggleButton>
<ToggleButton maxWidth="Infinity" fx:id="coverFlowToggle" mnemonicParsing="false" toggleGroup="$albumViewToggleGroup">
<graphic>
<Glyph fontFamily="FontAwesome" icon="ELLIPSIS_H"></Glyph>
</graphic>
<VBox.margin>
<Insets top="10.0"/>
</VBox.margin>
</ToggleButton>
</buttons>
</SegmentedButton>
The SegmenedtButton consumes the full width (represented by the red line), though the ToggleButtons are not. I checked this by setting a background color.
I would like that the ToggleButtons are stretched so that they are each 1/3 of the width of the SegmentedButton. How can i achive this?
According to the documentatiom mathematical operators can be used in fxml bindings.
So something like this can be used:
<SegmentedButton fx:id="segButton" maxWidth="1.7976931348623157E308" >
<buttons>
<ToggleButton fx:id="option1" maxWidth="1.7976931348623157E308" prefWidth="${segButton.width / 4}" text="K3" />
<ToggleButton fx:id="option1" maxWidth="1.7976931348623157E308" prefWidth="${segButton.width / 4}" text="K2" />
<ToggleButton fx:id="option1" maxWidth="1.7976931348623157E308" prefWidth="${segButton.width / 4}" text="K1" />
<ToggleButton fx:id="option1" maxWidth="1.7976931348623157E308" prefWidth="${segButton.width / 4}" text="K1,1" />
</buttons>
</SegmentedButton>
Probably no longer needed, but should hopefully be useful for anyone who winds up googling this.
I doubt that you still need help with this problem, but for anyone like me, who googled the problem and got here, here's how I solved it:
button1.prefWidthProperty().bind(segmentedButtons.widthProperty().divide(2));
button2.prefWidthProperty().bind(segmentedButtons.widthProperty().divide(2));
segmentedButtons.getButtons().addAll(button1, button2);
segmentedButtons.setMaxWidth(Double.MAX_VALUE);
So basically, for every ToggleButton that you add to SegmentedButton you bind preferred width to the actual width of SegmentedButton divided by the number of buttons. Since it's binding, the width will adjust on resizing the window, so you need to do it only once on creation. And if you want, you can divide width in some other way to make some buttons bigger and some smaller.
I am currently trying to build a picture viewing program using java and an FXML window. I have had a fiddle about - getting to know FXMLs and accessing them from a program and was able to get buttons to disappear and reappear - but upon adapting said code for this picture viewer, I found that the FXML panel wouldn't open upon running the file. There are no errors/warnings besides warnings about (as yet) unused libraries being declared. Upon start up, there's no error messages, no text boxes and no outputs to the terminal so I can't supply anything from there. The code is as follows:

String viewerFxml = "WindowPanel.fxml";
AnchorPane page = (AnchorPane)fxmlLoader.load(
this.getClass().getResource(viewerFxml).openStream());
Scene scene = new Scene(page);
stage.setScene(scene);

The file "Picture1.png" is located in the workspace with the position being:
WorkspaceA/Practice1/scr/practice1/Picture1.png
Background
The # notation is used in JavaFX to specify a relative location which is "assumed to be located at a path relative to the current FXML file".
What is Wrong
You load the FXML as a stream using the following code:
AnchorPane page = (AnchorPane)fxmlLoader.load(
this.getClass().getResource(viewerFxml).openStream());
A steam is not a location, so there is no concept of locations relative to the stream.
If I run your application locally, I will get a stack trace where it cannot find the picture file (here is just the last portion of it):
Caused by: java.lang.IllegalArgumentException: Invalid URL or resource not found
at javafx.scene.image.Image.validateUrl(Image.java:1081)
... 18 more
How to fix it
Set the location in the loader prior to loading the FXML:
fxmlLoader.setLocation(getClass().getResource(viewerFxml));
AnchorPane page = fxmlLoader.load();
The loader will then be able to resolve the relative reference to your picture file.
Check your directory structure and build output
This may or may not be an issue for you.
You specify your image using the location specifier:
<Image url="#Picture1.png" />
Which tells the FXMLLoader to look for Picture1.png at the same location it got the FXML from; e.g. if you loaded the FXML from the filesystem, the image would be in the same folder on the filesystem as the FXML - similarly if you load the FXML from a jar, the image should be on the same path within the jar as your FXML was retrieved from.
You state that you place your picture at: WorkspaceA/Practice1/scr/practice1/Picture1.png. I'm not sure what that location is, but if it is the same location as your MainProgram.java source, your MyController.java source, WindowPanel.fxml and if your build system is set to copy the image and fxml over to the compile and packaging target directory, then it will work fine - if it's not, you will need to move the image to the appropriate source location.

I'm programming a app with JavaFX and Scene Builder. I want to create a container and insert an image inside.
But, the container have a size so if the image goes out that limits you can't see this image.
For Example, make a container and make the image too much bigger outside that, but just see what is inside the container.
Is that possible?
Solution
Use an ImageView (which is a node container for an Image). You can set a viewport on the ImageView to have the view render a specific part of an image.
Alternative Implementation
Specify your image in CSS and use combinations of -fx-background-image, -fx-background-repeat, -fx-background-position and -fx-background-size as defined in the JavaFX CSS reference guide.
The rest of this answer deals with just the FXML based solution and not the CSS based solution.
Code Based Sample
Here is a code snippet (adapted from the ImageView javadoc) which demonstrates setting a viewport in code:
Image image = new Image("flower.png");
ImageView view = new ImageView();
view.setImage(image);
Rectangle2D viewportRect = new Rectangle2D(40, 35, 110, 110);
view.setViewport(viewportRect);
FXML Based Sample
Here is some FXML to demonstrate the viewport approach.
<ImageView pickOnBounds="true">
<image>
<Image url="http://icons.iconarchive.com/icons/vincentburton/diaguita-ceramic-bowl/128/Diaguita-Ceramic-Bowl-4-icon.png" />
</image>
<viewport>
<Rectangle2D minX="35.0" minY="55.0" width="55.0" height="40.0" />
</viewport>
</ImageView>
Here is a complete example which you can load up into SceneBuilder. The first ImageView displays an unclipped image, the second ImageView displays a clipped image.
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.geometry.Insets?>
<?import javafx.geometry.Rectangle2D?>
<?import javafx.scene.image.Image?>
<?import javafx.scene.image.ImageView?>
<?import javafx.scene.layout.StackPane?>
<?import javafx.scene.layout.VBox?>
<StackPane id="StackPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="-1.0" prefWidth="-1.0" style="-fx-background-color: burlywood;" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2">
<children>
<VBox alignment="CENTER" prefHeight="-1.0" prefWidth="-1.0" spacing="10.0" style="-fx-background-color: cornsilk;">
<children>
<ImageView pickOnBounds="true">
<image>
<Image url="http://icons.iconarchive.com/icons/vincentburton/diaguita-ceramic-bowl/128/Diaguita-Ceramic-Bowl-4-icon.png" />
</image>
</ImageView>
<ImageView pickOnBounds="true">
<image>
<Image url="http://icons.iconarchive.com/icons/vincentburton/diaguita-ceramic-bowl/128/Diaguita-Ceramic-Bowl-4-icon.png" />
</image>
<viewport>
<Rectangle2D height="40.0" minX="35.0" minY="55.0" width="55.0" />
</viewport>
</ImageView>
</children>
<padding>
<Insets bottom="10.0" left="10.0" right="10.0" top="10.0" />
</padding>
</VBox>
</children>
<padding>
<Insets bottom="10.0" left="10.0" right="10.0" top="10.0" />
</padding>
</StackPane>
On using the FXML Based Sample in SceneBuilder
To generate the FXML, the majority of the work was done in SceneBuilder, but setting the viewport was done by hand editing the FXML saved from SceneBuilder (because SceneBuilder 1.1 does not possess the UI to set the viewport on ImageViews from within the SceneBuilder tool). After hand-editing the FXML to add the viewport, you can reload the FXML in SceneBuilder and SceneBuilder will render the viewport in the hand-edited FXML fine.
Also, SceneBuilder 2 build 14 preview did not display images that are located using the http protocol (SceneBuilder 1.1 did not have an issue with this).
