FX1.2: Understanding Bounds Posted by aim on July 9, 2009 at 8:15 PM PDT This is the first in a series of articles to cover layout for JavaFX 1.2. We changed the api a bit (for the better of course), but that hasn't made it any easier to explain. The visuals displayed within a JavaFX scene are fully represented by a 2D scene graph where each visual element (line, path, image, etc) is represented by a distinct node with variables that can be easily manipulated dynamically. Bounds Class In JavaFX1.2, a node's rectangular bounds are represented by the Bounds class which provides init-only minX, minY, maxX, maxY, width, height variables. Note: The Bounds class was introduced in JavaFX1.2 in anticipation of adding Z in the future. Node Bounds Variables A Bounds object is always relative to a particular coordinate system, and for each node it is useful to look at bounds in both the node's local (untransformed) coordinate space, as well as in its parent's coordinate space once all transforms have been applied.

JavaFX 1.3: Taming the Layout Beast | Aim's Blog In the midst of celebrating JavaFX 1.3‘s performance improvements and CSS-stylable controls, let’s not forget about changes aimed to tame the beast we call “layout”. My JavaFX 1.2 layout blog covered the fundamentals of bridging our declarative, animating scene-graph with traditional GUI layout and here I’ll follow up with some layout guidelines and a series of blogs describing how the changes we made in 1.3 are expressly intended to make your life easier, even if at first, being human, you feel a little resistant to change. Most of the core concepts in JavaFX layout (logical vs. visual bounds, resizable vs not, use of binding vs. containers) remain complex and there’s no getting around spending time to understand them (not unlike 2D or CSS). Use the Container classes (HBox, VBox, Stack, Flow, Tile, *Grid (preview)) (rather than binding or static layout) whenever possible, as they handle the complexities of dynamic scene-graph layout for you.

Optimization Algorithm Toolkit (OAT) About About The Optimization Algorithm Toolkit (OAT) is a workbench and toolkit for developing, evaluating, experimenting, and playing with classical and state-of-the-art optimization algorithms on standard benchmark problem domains. The software includes reference algorithm implementations, graphing, visualizations, and much more. OAT provides a functional computational intelligence library for investigating existing algorithms and problems, as well as implementing new problems and algorithms. Built on top of this library is a simple explorer and experimenter graphical user interface to provide a basic understanding of the functionality in the library. OAT is designed for three core classes of user: Interested Amateurs that may, or may not have training in artificial intelligence and computer science, and that are interested in playing with algorithms and problems in the explorer and experimenter graphical user interfaces.

Getting Started with JavaFX: Animation and Visual Effects in JavaFX | JavaFX 2 Tutorials and Documentation You can use JavaFX to quickly develop applications with rich user experiences. In this Getting Started tutorial, you will learn to create animated objects and attain complex effects with very little coding. Figure 5-1 shows the application to be created. Figure 5-2 shows the scene graph for the ColorfulCircles application. The tool used in this Getting Started tutorial is NetBeans IDE. Set Up the Application Set up your JavaFX project in NetBeans IDE as follows: From the File menu, choose New Project.In the JavaFX application category, choose JavaFX Application. Set Up the Project Delete the ColorfulCircles class from the source file that NetBeans IDE generated and replace it with the code in Example 5-1. Example 5-1 Basic Application For the ColorfulCircles application, it is appropriate to use a group node as the root node for the scene. You can compile and run the ColorfulCircles application now, and at each step of the tutorial, to see the intermediate results. Add Graphics Add Animation

Clarkeman's Weblog Last June, I demonstrated a JavaFX class to access the JSON Weather Service from the GeoNames geographical database at Please see my earlier blog, for more information about the Weather Service and how I implemented it in a pre-release version of JavaFX. With the release of JavaFX 1.0, much has changed so I decided to update this example. I enhanced the example a little, so now you can enter an airport code. The Weather class is basically the same as before. package jsonweather; // ICAO code in US is typically 'K' + IATA airport code// MCO is Orlando FL US IATA code, so ICAO is KMCO.// New York - JFK is KJFK.// See airportCode = "MCO";var url = bind " var jsonInput: InputStream; // holds the input stream for the JSON data input.requestFocus();
bash on Mac OS X bash on Mac OS X Pages: 1, 2 Regular Variables A regular variable typically holds a piece of information that you use frequently. Because variables in shell scripts are loosely typed, unlike C and Java, variables can hold virtually anything: a number, string, or composite value such as an array or hash. Creating a variable is pretty painless: name=value, and retrieving its value is almost as easy: $name. Thus, if you wished to see the current date when opening a new Terminal window, you could place the following lines in your profile: mydate=`date "+%H:%M:%S %m/%d/%y"` echo "hi $USER, the current time is $mydate" For more information on shell scripting, refer to Chris Stone's series of articles mentioned in the introduction. Environment Variables Environment variables are essentially a special case of shell variables; they are visible to all child processes that are spawned from the shell. By convention, the names of environment variables are all uppercase. Aliases Setting Your Prompt
JavaFX 8 Tutorial - Part 4: CSS Styling | code.makery.ch Topics in Part 4 CSS StylingAdding an Application Icon CSS Styling In JavaFX you can style your user interface using Cascading Style Sheets (CSS). This is great! In this tutorial we will create a DarkTheme inspired by the Windows 8 Metro design. Getting Familiar with CSS If you want to style your JavaFX application you should have a basic understanding of CSS in general. For more JavaFX specific information about CSS: Default JavaFX CSS The default source for CSS styles in JavaFX 8 is a file called modena.css. Unzip the jfxrt.jar. This default style sheet is always applied to a JavaFX application. Hint: It helps to look at the default CSS file to see which styles you might need to override. Attaching CSS Style Sheets Add the following CSS file called DarkTheme.css to the view package. DarkTheme.css We now need to attach the CSS to our Scene. Attach CSS to RootLayout.fxml Open the file RootLayout.fxml in Scene Builder. Attach CSS to PersonEditDialog.fxml Attach CSS to PersonOverview.fxml
