I've been struggling with this problem regarding JavaFx ImageView class. the code written in fxml
<ImageView fitHeight="634.0" fitWidth="1204.0" layoutX="38.0" layoutY="83.0" pickOnBounds="true" preserveRatio="true" rotate="-8.0">
<image>
<Image url="#\PCI%20logoRYB.png" />
</image></ImageView>
and it keeps showing this error
Cannot resolve file '\PCI%20logoRYB.png'
I created all this using scene builder and the image is at the same place as the fxml file/s
Try remove \ from your url, like below. Image must be in the resources directory.
<ImageView fitHeight="634.0" fitWidth="1204.0" layoutX="38.0" layoutY="83.0" pickOnBounds="true" preserveRatio="true" rotate="-8.0">
<image>
<Image url="#PCI%20logoRYB.png" />
</image></ImageView>
if you are using eclipse IDE after adding resources like images you need to clean your project to reload all new resource files which was added to project.

when I build a jar file an run it, i can't see the image.
In Eclipse it is working all good.
The Image should be a Button
<effect>
<ImageInput>
<source>
<Image url="file:./images/record_by_felickzs.PNG" />
</source>
</ImageInput>
</effect>
that is because on eclipse the image is not packed so it is accessible the way you are doing it, however when you export a jar file the image is packed and you can not access file inside the jar that way,,, use relative path instead:
<effect>
<ImageInput>
<source>
<Image url="#../../images/record_by_felickzs.PNG" />
</source>
</ImageInput>
</effect>
edit : replace PNG with png
I'm trying to write a simple Java app for modifying and visualizing logic circuits by dragging gates and connections about. I'm using SceneBuilder to put the interface together. Right now, I'm stuck at getting the available basic logic gates to display in their proper bar and respond to being interacted with. More accurately, I'm trying to get one gate to just display some console output, to confirm that the GUI-logic connection is working.
The biggest problem I'm having is that the ImageViews of the gates, possibly along with some other FXML elements, refuse to display in the actual compiled app for some reason, even though they work and react correctly in SceneBuilder and in its "Preview" feature.
I had to do some experimenting with wrapping them in various other FXML elements which I didn't really understand because apparently ImageWiew doesn't have a onDragDetected() method, even though the text input field for it is available in SceneBuilder. The intended work-in-progress app layout can be seen plainly enough directly from SceneBuilder on the first picture. Compare with the second one, which is of the actual running application.
Possibly relevant code:

I thus need to know:
Why are those gates(or at least one) not displaying as intended? And what's with the ScrollPane, why is it not displaying its sliders as it is in SceneBuilder? What things do I need to set up differently or wiggle with to get those gates to show up and interact correctly?
After a bit of random crapshooting, I found a solution.
First, I looked into View->Show Sample Controller Skeleton. There, I noticed that the handleDragDetectedNAND() method does not have any modifier, whereas mine had private, copied early from some tutorial or the other. I removed the modifier and the application now works. If anyone who passes by cared to explain why this is the case(I have no idea and no time to research, deadline's fast approaching), the value of this answer would rise significantly.

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:
package practice1;
import javafx.application.Application;
import javafx.stage.Stage;
import java.io.IOException;
import javax.imageio.*;

import java.awt.image.BufferedImage;
public class MainProgram extends Application{
public void start(Stage stage) {
try {
FXMLLoader fxmlLoader = new FXMLLoader();
String viewerFxml = "WindowPanel.fxml";
AnchorPane page = (AnchorPane)fxmlLoader.load(
this.getClass().getResource(viewerFxml).openStream());
Scene scene = new Scene(page);
stage.setScene(scene);
stage.show();
} catch (IOException ex) {
Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, null, ex);
System.exit(1);

</AnchorPane>
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).
