Creating a New Composer

---

A new MIDlet Composer can be created by selecting the Create MIDlet menu item from the Create menu in the IDE. A MIDlet Composer can also be created by pressing the Create MIDlet button on the tool bar.

The MIDlet Composer

A MIDlet Composer is used to create a Java Application which can run on Java 2 Micro Edition (J2ME) devices using the Mobile Information Device (MID) Profile. Such devices typically include cell phones and wireless pagers, but also include devices running the Palm OS. MIDlets are similar to applications which are used in "Standard Edition" Java, but have a greatly restricted user interface and API. In general, the author of a MIDlet cannot specify the exact placement of GUI elements, but rather requests the relative placement of elements. This restriction makes sense when it is realized that MIDP devices could potentially have screens as small as 96x54 pixels. While Palm OS devices don't have as wide a range of screen sizes, different devices do have different characteristics and this is handled by the MIDP implementation on the Palm OS.

A MIDlet composer will generate a single Java source file corresponding to a public MIDlet class.
