In this activity you will learn how to respond to user input events. Handling input is a key part of any graphical user interface. Buttons, sliders, menus, etc., all of these components need handler code that is called when the user moves the mouse pointer over the component and clicks or drags.
In this activity, you will:
- work with an interactive application that demonstrates animated UI controls for a media player
Skills you will learn include:
- writing and installing input event handlers
- responding graphically to user actions
- responding functionally to user actions
- 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 8: Bringing Interactivity to 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.
