In this activity you will learn to use the JavaFX layout mechanism. The layout mechanism makes it easy to arrange graphical objects on the screen, and then have them reposition themselves automatically if window geometry is changed. Instead of specifying excatly where objects should be displayed, you describe how objects should be positioned relative to each other, and the layout mechanism takes care of doing the right thing.
In this activity, you will:
- explore small example applications that make use of the JavaFX layout mechanism
Skills you will learn include:
- understanding how to use the JavaFX layout mechanism for things like lists (such as media playlists) or UI components (such as media player controls)
- 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 6: Laying Out GUI Elements 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.
