Please take a look at a new site I am working on. It focuses on Java FX 2 application development. Thanks!

I created my own version of a Ribbon Menu. I hope you find it useful.

Personally, I believe the coloring may be too light on the ribbon menu itself. I decided to leave it alone and just post it on WordPress as is. It should be easy for you to manipulate the colors in the CSS style sheet. Also the icons do not seem to render very well. The icons I have selected are too large so they are scaled down. That could be the problem.

Please be mindful that I am no expert programmer – so take this for what it is…some buttons and such on the screen. Here we go!

My Design Approach:
I decided to separate out the code into distinct parts. There is the RibbonBar class which is to be dropped into the main application. Next are the Tab classes which include the Home Tab and Commerce Tab.  Then there are the individual regions on the tabs such as Actions, Clipboard, Font, etc.

Visual Issues:
When running the program you will notice some visual issues. I didnt spend a lot of time making it very professional. I believe I did enough to serve the purpose of learning what I wanted. For example, you will notice I didnt style the SplitMenuButton or ChoiceBoxes. However, I did style some other buttons. My goals were to continue working with layout managers and CSS styles.

Worth Noting:
None of the buttons do anything except print to console. However I would like to share a few notes.

1. SplitMenuButton.
I used a SplitMenuButton in the “Clipboard” region on the Home Tab. As pointed out in the JavaDocs, the SplitMenuButton is divided into two sections: a Button and Menu. You will need to program for the Button’s Event Handler as well as the MenuItem Event Handlers.

When a menu item has been selected, the event is not transferred to the buttons event handler. So the Button does not retain the last selected menu event.

In the sample code below, a SplitMenuButton with a “Clipboard” icon and 3 menu items is created. In this example there are 4 events that are assigned to the SplitMenuButton. Three of these are for each menuItem and the last is for the Button itself.

The clipboard image is retrieved from the images folder and stored in an Image object. The image is then added to an ImageView so it can be rendered on the button. You will see I resized the image to 24H x 24W.

The setGraphicTextGap sets the vertical spacing between the text and image. Based on what I am able to determine, if the GraphicTextGap is not specified, the default is 3 pixels between the icon and Button text. In the example photo, I compare the difference between no GraphicTextGap and 20 pixel text gap.

    /**
     * Creating a SplitMenuButton.
     */
    private void buildSplitMenuButton() {

        //Create button and set text.
        this.pasteButton = new SplitMenuButton();
        this.pasteButton.setText("Paste");

        //Set alignment of button to text. This puts btn text below the image icon.
        this.pasteButton.setContentDisplay(ContentDisplay.TOP);

        //Retrieve and set image of clipboard. I will set image size to 24x24,
        //preserve the ratio and enable smoothing in the Image constructor.
        String imgPath = "/ui/common/images/clipboard.png";
        Image clipboard = new Image(this.getClass().getResourceAsStream(imgPath),
                24.0, 24.0, true, true);

        //Create an ImageView for showing image.
        ImageView imageView = new ImageView(clipboard);

        //Set the gap b/n graphic and text. Assign the ImageView to the button.
        this.pasteButton.setGraphicTextGap(5.0);
        this.pasteButton.setGraphic(imageView);

        //Paste Menu Item
        MenuItem mnuPaste = new MenuItem("Paste");
        mnuPaste.setOnAction(new EventHandler() {

            @Override
            public void handle(Event event) {
                System.out.println("Paste clicked.");
            }

        });

        //Paste Special Menu Item
        MenuItem mnuPasteSpecial = new MenuItem("Paste Special...");
        mnuPasteSpecial.setOnAction(new EventHandler() {

            @Override
            public void handle(Event event) {
                System.out.println("Paste Special clicked.");
            }

        });

        //Paste As Hyperlink Menu Item
        MenuItem mnuPasteHyperlink = new MenuItem("Paste as Hyperlink");
        mnuPasteHyperlink.setOnAction(new EventHandler() {

            @Override
            public void handle(Event event) {
                System.out.println("Paste as Hyperlink clicked.");
            }

        });

        //Add all MenuItems to the MenuSplitButton's menu options.
        this.pasteButton.getItems().addAll(mnuPaste, mnuPasteSpecial, 
                mnuPasteHyperlink);

        //Set the click event of the Button itself. 
        this.pasteButton.setOnAction(new EventHandler() {
            @Override
            public void handle(Event arg0) {
                System.out.println("Button Clicked.");
            }
        });

    }

2. ToggleButtons
I created two types of ToggleButtons. One type is for the Bold, Italics, and Underline buttons. These are independent ToggleButtons that allow each to be selected or deselected.

The other series of ToggleButtons are grouped together in a ToggleGroup. For example, the Superscript and Subscript buttons should not be mutually independent of each other. If one is selected the other should be removed.

As for grouping them together as if one seamless series of buttons is done in CSS styles. I use a GridPane layout manager to group them together. The CSS stylesheet (tabs.css) applies the rounded border on the ends. It also applies a top and bottom border for middle buttons.

/**
  * Middle Toggle Button
  */
.middleToggleButton {
    -fx-background-insets: 0 0 0 1, 1 0 1 0, 2 0 2 0;
    -fx-background-radius: 0 0 0 0, 0 0 0 0, 0 0 0 0;
}

 /**
  * Left side Toggle Button
  */
.leftToggleButton {
    -fx-background-insets: 0 0 0 1, 1 0 1 1, 2 0 2 2;
    -fx-background-radius: 0 0 0 5, 4 0 0 4, 3 0 0 3;
}

 /**
  * Right side Toggle Button
  */
.rightToggleButton {
    -fx-background-insets: 0 1 0 0, 1 1 1 0, 2 2 2 0 ;
    -fx-background-radius: 0 5 0 0, 0 4 4 0, 0 3 3 0;  
}

3. Ribbon Container Background
To style the ribbon strip background, I created a an HBox. Each component added to an HBox will be positioned side by side so it seems to be the appropriate container. I set the spacing between each node that is added by calling the setSpacing() method. I set spacing to 5px.

container.setSpacing(5);

The gradient can be found in the tabs.css style sheet. There are 5 color stops to create the multiple gradient effects. It looks like this:

#container {
    -fx-padding: 3px;
    -fx-background-color: 
        linear-gradient(#ffffff 0%, #ced3da 4%, #c1c6cf 17%, 
        #b4bbc5 18%, #e5ebeb 100%);
}

4. Ribbon Component Group
I’m not sure what to call the group of related controls. So I will go with a component group. This group is similar to the container background shown above. The primary difference is that I chose to use a VBox as the root node for each component. The CSS styles apply the gradient and rounded corners.

.toolbarContainer {
    -fx-background-color: 
        linear-gradient(#dae0e7 0%, #ced4dd 14%, 
        #c8ced7 15%, #dfe5e6 100%),
        linear-gradient(#bdbfc1 0%, #9a9c9f 14%, 
        #888b90 15%, #838686 100%),
        linear-gradient(#eef1f6 0%, #e1e6ee 14%, 
        #d5dbe7 15%, #eef4f4 79%, 
        #ced4e6 79%, #afb6c8 100%);

    -fx-background-insets: 1 0 1 1, 1, 2;
    -fx-background-radius: 5,4,3;
    -fx-padding: 4 8 0 8;
}

I am excited about this one because I used Jasper’s technique of manipulating the background radius and background insets. Specifically, I added a white shadow effect to the right side of each component. I will explain that one another day. A user would probably never notice but its the details that make a nice presentation. Would you agree? I will explain the CSS styles and how I pieced them together another day.

I hope you like the demonstration! Gregg

Java FX 2 Linear Gradients

March 23, 2012 3 comments

I really didnt understand the concept of multiple linear gradients so I decided to study Jasper’s demo on styling fx buttons with CSS. I picked the example “Large iPad Dark Grey” for this demonstration.

As you can see, multiple gradients make up the glossy button effect. I am visual person so to me this example is stunning.

I was pleasantly surprised at the simplicity after reviewing the CSS styles that create these buttons. I suspect its one thing to say it looks easy but I am sure it requires creativity to blend the colors.

The concept behind building this button is working with multiple linear gradients. The trick is creating multiple layers, each with their own gradient effect and adjusting the background radius and background insets.

#ipad-dark-grey {
    -fx-background-color:
        linear-gradient(#686868 0%, #232723 25%, #373837 75%, #757575 100%),
        linear-gradient(#020b02, #3a3a3a),
        linear-gradient(#9d9e9d 0%, #6b6a6b 20%, #343534 80%, #242424 100%),
        linear-gradient(#8a8a8a 0%, #6b6a6b 20%, #343534 80%, #262626 100%),
        linear-gradient(#777777 0%, #606060 50%, #505250 51%, #2a2b2a 100%);
    -fx-background-insets: 0,1,4,5,6;
    -fx-background-radius: 9,8,5,4,3;
    -fx-padding: 15 30 15 30;
    -fx-font-family: "Helvetica";
    -fx-font-size: 18px;
    -fx-font-weight: bold;
    -fx-text-fill: white;
    -fx-effect: dropshadow( three-pass-box , rgba(255,255,255,0.2) ,
                1, 0.0 , 0 , 1);
}

Take notice that there is a background inset and background radius that is paired with each linear gradient. In this example there are 5 linear gradients, 5 background-radius settings, and background-insets settings.

The [unattractive] example below color coordinates the matching linear-gradient and background properties together. I hope it helps to visualize the relationship between the linear-gradient and its inset and radius.

In theory, Jasper has layered multiple background fills on top of each other. With each overlay he has reduced the radius and increased the background inset.

-fx-background-color:
    linear-gradient(#686868 0%, #232723 25%, #373837 75%, #757575 100%),
    linear-gradient(#020b02, #3a3a3a),
    linear-gradient(#9d9e9d 0%, #6b6a6b 20%, #343534 80%, #242424 100%),
    linear-gradient(#8a8a8a 0%, #6b6a6b 20%, #343534 80%, #262626 100%),
    linear-gradient(#777777 0%, #606060 50%, #505250 51%, #2a2b2a 100%);
-fx-background-insets: 0,1,4,5,6;
-fx-background-radius: 9,8,5,4,3;

How a linear gradient works

Using the example above in orange, here is how a linear gradient works. Starting from the top to the bottom, the first color is #686686 and transitions into color #232723. This consumes the first 25% of the button’s vertical space.

The next color #373837 will consume the next 50% of the button’s vertical space. And finally the color range stops at #757575.

Here is a demo program to show the layering effect one gradient at a time. I go into more detail with CSS button styles for JavaFX 2 apps on my website. Please have a look.

Working with JavaFX 2 Layout Managers

March 22, 2012 5 comments

My original objective was to work with the GridPane layout manager. During my learning process I ended up working with the VBox, HBox, BorderPane and GridPane.

Below is the code. Please see attached PDFs. I have two versions of each PDF with our without line numbers. Also consider taking a look at several tutorials on other layout managers in JavaFX 2 on javadesk.co website.

Linking a CSS Style Sheet to JavaFx Scene Graph

March 21, 2012 Leave a comment

The recommended way to link your CSS styles to a Scene Graph in your application is through the stylesheets variable.

Set your css paths relative to your application’s concrete class. This is the class that will extend Application. In the sample project pictured below, the Concrete Application Class is my Driver.java file.

For more information on working with CSS Style Sheets in JavaFX 2 applications please see my article on JavaDesk website. I provide an example where a user can swap Style Sheets dynamically using a ChangeListener.

Driver.java has the class declaration:

public class Driver extends Application {public static void main(String[] args) {
launch(args);
}@Override
public void start(Stage primaryStage) {}
}

Example 1: Connect to CSS Style Sheet in same Package

//Demonstrate in one long line of code.
scene.getStylesheets().add(this.getClass()
.getResource(“Styles.css”).toExternalForm());

//Break up into two lines of code.
String cssURL = this.getClass().getResource(“Styles.css”)
.toExternalForm();
scene.getStylesheets().add(cssURL);

//Replace this keyword with full URL of main class.
scene.getStylesheets().add(ui.Driver.class.getResource(“Styles.css”)
.toExternalForm());

Example 2: Connect to CSS Style Sheet in another Package

//Get a style sheet that is not in same package as Driver.
scene.getStylesheets().add(this.getClass().
getResource(“/cssStyles/base.css”).toExternalForm());

Example 3: Get Multiple CSS Style Sheets

//Use addAll() to attach several stylesheets.
String cssFile1 = this.getClass().getResource(“x.css”)
.toExternalForm();String cssFile2 = this.getClass().getResource(“Styles.css”)
.toExternalForm();String cssFile3 = this.getClass().getResource(“/cssStyles/base.css”)
.toExternalForm();scene.getStylesheets().addAll(cssFile1, cssFile2, cssFile3);
