In this activity you will continue to explore JavaFX nodes, the elements that create the graphics that are displayed on the screen. You will see how multiple nodes in a scene can be grouped together so that you can operate on them together. This makes it easier to build up complex graphics from simpler parts, and them move them around in the scene like they are a single object.
In this activity, you will:
- create an application containing several graphical objects
- group the objects together so they can be treated as a single, more complex object
Skills you will learn include:
- a deeper understanding of the JavaFX Stage/Scene/Node architecture
- building up complex graphical objects from simpler objects, and using grouping to allow operations to be applied to the composite object
- Open NetBeans, and create a new project. Under the File menu, select New Project, and go through the new project wizard, creating a JavaFX project. Remember, if you need help, use the forum! Once you have created the project, you can make it the Main Project to make it easier to perform your edit/build/run cycle.
- Now go to Lesson 3: Presenting UI Objects in a Graphical Scene in the JavaFX GUI Applcation tutorial. Go through the tasks of this lesson.
- Submit your project that you created to the activity. You will submit a jar file (a java archive file) that contains your runnable program. To find the jar file, open your project in NetBeans, and note that in the project pane, there are 3 tabs: Projects, Files, Services. Select the Files tab. Expand your project folder by clicking on the '+' sign. You should see a folder called 'dist'. Expand the dist folder, you will probably see a few files and maybe some folders. One of the filenames should end in .jar. This is the file that you will submit. Open the context menu on that file (on Windows, right-click on the file; on Mac, Ctrl-click on it), and select 'properties' from the menu. One of the properties will be the full path to where the jar file lives on your system. Use your file browser to go get the file, and submit it.
