I am trying to create a splash screen like the example I've provded.
It seems that AnchorPane does not allow transparent background, I've tried setting the css of the AnchorPane to -fx-background-color: rgba(255,0,255,0.1) ; but the white background still shows up.
All I have in my fxml file is a AnchorPane with ImageView with contain the png image
I've looked everywhere but can't find any solution, any help would be appreciated. Thanks
Try this JavaFX splash sample created for the Stackoverflow question: Designing a splash screen (java). And a follow up sample which also provides application initialization progress feedback.
JavaFX does offer the Preloader interface for smooth transfer from splash to application, but the above samples don't make use of it.
The splash samples above also don't do the transparent effect, but this dialog sample shows you how to do that and you can combine it with the previous splash samples to get the effect you want.
The transparent effect is created by:
stage.initStyle(StageStyle.TRANSPARENT).
scene.setFill(Color.TRANSPARENT).
Ensuring your root node is not an opaque square rectangle.
Which is all demonstrated in Sergey's sample.

How to use javaFX Preloader with stand-alone application in Eclipse?
Update Apr 2016 based on additional questions
the preloader image isnt in the foreground. I have tried stage.toFront(), but doesnt help.
A new API was created in Java 8u20 stage.setAlwaysOnTop(true). I updated the linked sample to use this on the initial splash screen, which helps aid in a smoother transition to the main screen.
For Java8+
For modena.css (the default JavaFX look and feel definition in Java 8), a slight shaded background was introduced for all controls (and also to panes if a control is loaded).
You can remove this by specifying that the default background is transparent. This can be done by adding the following line to your application's CSS file:
.root { -fx-background-color: transparent; }
If you wish, you can use CSS style classes and rules or a setStyle call (as demonstrated in Sergey's answer) to ensure that the setting only applies to the root of your splash screen rather than all of your app screens.

how to make transparent scene and stage in javafx?
You need to have transparent Stage and Scene for that. Pane itself doesn't have a color.
public void start(Stage primaryStage) {
Button btn = new Button("Say 'Hello World'");
AnchorPane root = new AnchorPane();
root.getChildren().add(btn);
// Java 8: requires setting the layout pane background style to transparent
// https://bugs.openjdk.java.net/browse/JDK-8092764
// "Modena uses a non-transparent background by default"
root.setStyle("-fx-background-color: transparent;");
Scene scene = new Scene(root, 300, 250, Color.TRANSPARENT);
primaryStage.initStyle(StageStyle.TRANSPARENT);
primaryStage.setScene(scene);
primaryStage.show();
}

I would like to know how can I adjust the color of my top ( navigator ) of my program, right now it looks like that:
https://i.imgur.com/NdBUQzt.png
but I want it to be colored, or to make it a part of my software, like spotify does:
https://46c4ts1tskv22sdav81j9c69-wpengine.netdna-ssl.com/wp-content/uploads/2017/06/ef6b137fb60f5671e2d92a8096442a46.png
^ You can notice that the close/minimize/maximize buttons are colored ( black ) and are not in a new line, but in the same level as the software.
Another example would be Word for example:
https://filestore.community.support.microsoft.com/api/images/561dc05e-f679-40d0-8a0d-983f3d90333b
I have heard about some solutions included making my own buttons, and make their functionality to behave like the native's windows 10 ( for example ) one, but in that two cases I listed above ( Spotify and Word ), the buttons are native to the OS, I mean I can tell it's a real windows 10 close/minimize/maximize buttons.
It can be done in any way at javaFX? ( not sure if it's worth mention but I also use an Visual editor - Scene builder )
Thanks in advance.
A possible approach to your problem would be to remove the default layout of the primary stage and start modifying it by yourself. To do that you have to use an undecorated toolbar. You do that at your stage controller:
primaryStage.initStyle(StageStyle.UNDECORATED);
After that you can create your customized toolbar. Here is a very basic example:
primaryStage.initStyle(StageStyle.UNDECORATED);
BorderPane borderPane = new BorderPane();
borderPane.setStyle("-fx-background-color: green;");
ToolBar toolBar = new ToolBar();
int height = 25;
toolBar.setPrefHeight(height);
toolBar.setMinHeight(height);
toolBar.setMaxHeight(height);
toolBar.setStyle("-fx-background-color: blue;");
borderPane.setTop(toolBar);
primaryStage.setScene(new Scene(borderPane, 300, 250));
primaryStage.show();
Anyways you can play with the design and try different ways in order to fit your preferences.
As for the part of native toolbar buttons one idea would be imitating them.
Have a look in the following link how to design them.

I'm just starting with Scene Builder and java. I've laid out my main GUI but when I preview it, it has wide borders for all my h/v boxes, anchor panels, etc. How do I hide the borders when I actually run (preview) my UI? Is there a way in scene builder (preferred) or will I have to code this instead?
Default border on layouts
There is NO default-border on layouts which can be visible. In case, you need to remove border from layouts you can set css code using setStyle() method,
yourPane.setStyle("-fx-border-width: 0px");
You can also use external css document for styling components.
Wide border on preview
Actually, the fxml preview means that showing your design in a window. So you might get confused with window frame border as shown in the below preview,
But you can make borderles- window by styling your stage using initStyle(),
primaryStage.initStyle(StageStyle.UNDECORATED);
You can also use TRANSPARENT style as well but you have to manage your title bar for customized-window.

I have a 3D scene in JavaFX and need to overlay GUI over the 3D scene. I have tried adding buttons and text to the scene but they always appear in the 3d view as 3D objects. I have looked around and haven't found how to do it. The only workaround would be creating a whole new window and putting the settings there but that isn't an option in this case. Thanks for the help!!
Something like this
Or this
The best solution for what you are looking for is the SubScene, a built-in JavaFX container:
The SubScene class is the container for content in a scene graph. SubScene provides separation of different parts of a scene, each of which can be rendered with a different camera, depth buffer, or scene anti-aliasing. A SubScene is embedded into the main scene or another sub-scene.
If you have a look at the 3DViewer project, you'll find it is like the pictures you have posted:
You can find a small sample of how to add a subScene to a regular scene in this question.
I'm having a hard time figuring out how to make a transparent background for an application window in javafx. scene.setFill(null) seems to only work with stage.initStyle(StageStyle.TRANSPARENT). Doc for setFill says
Both a null value meaning paint no background and a Paint with transparency are supported, but what is painted behind it will depend on the platform.
but that doesn't make sense to me. It works (on windows 8) only with StageStyle.TRANSPARENT which removes the exit button and such which I still want.
I've looked at http://www.adam-bien.com/roller/abien/entry/completely_transparent_windows_stage_in and a few questions here.
Can this be done on windows?
I've been tinkering with similar settings, and this works for me:
#Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.initStyle(StageStyle.TRANSPARENT);
primaryStage.setOpacity(0.5);
primaryStage.setFullScreen(true);
Scene scene = new Scene(root, 300, 275);
primaryStage.setScene(scene);
scene.getStylesheets().add(Main.class.getResource("main.css")
.toExternalForm());
primaryStage.show();
}
...and the css
.root {
-fx-background-color: rgba(0,0,0,0.5);
}
You can use this library. It is a fully customizable JavaFx Stage (CustomStage). You can see in-detail description of how to use it in this CustomStage Wiki
It has,
Window resizing
Default action buttons and their behaviour (close, maximize/restore, minimize)
Window dragging
Window is automatically scaled as for screen resolution
Very responsive
Stylable
Can achieve transparency
Has in-built navigation panes and drawers
etc.
I have an application that uses a javafx Scene to render something, and I want to put that rendering into some GUI that I made, also in javafx. How would I do that?
Basically is there some container I can put a scene into and then put that container into the GUI.
Sorry if it's a newbie question, I am new to JavaFX
Java 8 has a SubScene, for which some possible uses (from the javadoc) are:
The SubScene class is the container for content in a scene graph.
SubScene provides separation of different parts of a scene, each of
which can be rendered with a different camera, depth buffer, or scene
anti-aliasing. A SubScene is embedded into the main scene or another
sub-scene. Possible use cases are:
Mixing 2D and 3D content
Overlay for UI controls
Underlay for background
Heads-up display
A SubScene is just a Node, so you can place it in the scene graph of an existing scene wherever you want. An example of SubScene usage is in the answer to: How to create custom 3d model in JavaFX 8?
Generally SubScenes are for mixing 2D and 3D content. If you are not doing that, then SubScenes probably don't apply to your situation and Uluk's answer will better serve your needs.
The scene has only a top parent node as a root. You can get it and to put into another scene.
((Pane) scene2.getRoot()).getChildren().add(scene1.getRoot());
