tTitle("Setting the Cursor for a Scene") Īn instance of the class represents a mouse cursor. String file = "file:///Path-To-Your-Image/javafx-logo.png" Public static void main(String void start(Stage stage) Public class FxSceneExample1 extends Application Javafx scene with a plain text editor example code#Setting the Cursor for a Scene 2.1 The Code This is the reason you use a Group or a VBox as the root node while creating a Scene object. The root node of a Scene Graph is a special branch node that is the topmost node. Classes that are subclasses of the Node class, but not the Parent class, represent leaf nodes, for example, Rectangle, Circle, Text, Canvas, or ImageView. If you want to add a branch node to a Scene Graph, use objects of one of its concrete subclasses, for example, Group, Pane, HBox, or VBox. It is the base class for all branch nodes in a Scene Graph. If the scene is resized, the Scene Graph is not laid out again. If a Group is the root node of a scene, the content of the Scene Graph is clipped by the size of the scene. Import. Group is a nonresizable parent node that can be set as the root node of a scene. For that we create a new class “ DartEditor” in “ at.” and make it extend “ .TextEditor“. Now that the parsing infrastructure is in place we can create our setup for the editor control. DartPresentationReconciler: This one is responsible to tokenize the different partitions eg to create keyword-tokens, ….DartPartitioner: This one is responsible for partitioning your source file into eg comment-sections, code-sections, string-sections, ….In our case we instruct it to generate some java code for us and your project explorer should show something similar to this. This section holds the configuration for the code generator. I won’t explain most of the files content because I’ve done that already in the last blog post “Defining source editors with a DSL” but in brief it holds the paritioning and tokenizing rules required to provide lexical highlighting for Google Dart. TODO We need a $ => IDENTIFIER_CHAR rule , "implements", "import", "library", "operator", "part", "set", "static" , "dynamic", "export", "external", "factory", "get" Keywords [ "abstract", "as", "assert", "deferred" Keywords [ "break", "case", "catch", "class", "const", "continue", "default" ![]() Rule _dftl_partition_content_type whitespace javawhitespace ', '' ] Multi_line _dart_multiline_comment '/*' => '*/' Multi_line _dart_multilinedoc_comment '/**' => '*/' Single_line _dart_singleline_comment '//' => '' Single_line _dart_singlelinedoc_comment '///' => '' Now paste the following content to the dart.ldef file: So open the project properties and navigate to LDef/Compiler check the “Enable project specific settings” and modify the Output Folder/Directory value to src/main/java The last step before we start defining our language is to make some modifications to the project. Eclipse will prompt you for adding the Xtext nature to your project because of course the DSL is implemented with the help of Xtext. We start with creating a package like “ at.” and there we add a file named “ dart.ldef”Īfter the file is created. Now that we have configured our project appropriately we can start defining our application. Step 2: Create a new maven projectįirst we need modify the source and target version for the Java compiler by adding:īecause the dependencies have not yet been released we need to add the Sonatype snapshot repository with:Īnd finally we add the JavaFX-Code editor component with:Īt the end your pom.xml should look like this: Javafx scene with a plain text editor example download#The following video demonstrates the final application in actionĪt the time of this writing e(fx)clipse 2.1 has not been released so the best option to get started is to download our all-in-one nightly build. To show you that those are not idle words the first blog showing the code editor components in action uses plain Java and maven as build tool – for those who want to use them in OSGi a blog will follow soon. ![]() Our main deployment platform is of course e4 on JavaFX but because we have a clean architecture based on IoC and services our components don’t know about OSGi and hence can be used in any Java(FX) application no matter if you run on OSGi or not. In my last blog post I introduced the DSL we’ll ship with e(fx)clipse 2.1 in August 2015. ![]()
