screen properties, button properties, soft button label areas, and icon properties. The tutorial also explains how to set color properties and how to run the emulator for the new device. Chapter 3 describes in depth the components of a device definition and explains how to create a device definition. Appendix A lists the property files for the default emulator, describes the properties for it, and lists the image and icon files for the default emulator. Appendix B explains how to add a bytecode

Customization Steps You customize the J2ME Wireless Toolkit for a new device in three simple steps: 1. Obtain the default J2ME Wireless Toolkit. The toolkit includes a default development environment and a Default Emulator. The Default Emulator is supplied with sets of device property files that enable the emulation of several generic wireless devices. 2. Create new device property files. A company that wants to have applications developed for specific devices using the toolkit can modify the de

For example, suppose the J2ME Wireless Toolkit is installed in the directory C:\WTK21. Then, the Main Device Property File for the device DefaultColorPhone is located at C:\WTK21\wtklib\devices\DefaultColorPhone\DefaultColorPhone.pro perties. For the remainder of this document, {j2mewtk.dir}, denotes the installation directory of the J2ME Wireless Toolkit. Chapter 1 Customizing the Wireless Toolkit 3

CHAPTER 2 Creating Device Property Files This chapter presents a simple tutorial that walks you through the procedures for creating a device property file. You will learn how to use the new device property files to enable the J2ME Wireless Toolkit to emulate applications for the device. See Chapter 3, “Examining Device Property Files” for a detailed reference on device properties, the custom-tailoring options available, and how to use them. In the following step-by-step tutorial, you will create

Note – All directory names in this chapter refer to the installation directory of the J2ME Wireless Toolkit. (If you chose the default option at installation, the directory is C:\WTK21.) 1. Copy the directory wtklib\devices\DefaultColorPhone and its contents as wtklib\devices\NewPhone. 2. Rename the main device property file wtklib\devices\NewPhone\DefaultColorPhone.properties to wtklib\devices\NewPhone\NewPhone.properties.
