Sun Microsystems Computer Accessories manual Obtain and Enter Image Files

Page 20

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.

Obtain and Enter Image Files

You need to provide image files for the new device. These image files should differ only in their representation of the active buttons. (Active buttons are those buttons used in the emulation of the device in the J2ME Wireless Toolkit.)

The image files are:

■a default image file showing the active buttons in normal unpressed position

■an image file showing the active buttons in a pressed position

■an image file showing the active buttons highlighted and an indicator light to indicate that backlighting is turned on the device

■an image of the network indicator icon in the enabled state

These images are used by the Emulator to show visual effects when the user moves the pointer over, or clicks on, a device button. The device backlight is turned when a MIDP API is being called or when communication over the network is taking place. An image file can be in JPEG, GIF, or PNG format.

1.Create the image files such that the size of the device's screen in each image is the same as the pixel size of the display on the real device.

For example, if the device has a screen of 96 pixels horizontally by 128 vertically, your images should have the same size as the screen.

2.Insert the new image files in the NewPhone directory in place of the following files, respectively:

wtklib\devices\NewPhone\ph1_neut.png wtklib\devices\NewPhone\ph1_press.png wtklib\devices\NewPhone\ph1_highlight.png wtklib\devices\NewPhone\indicator.png

3.Change the image file names in the following lines in NewPhone.properties, if they are different from the names already present.

default_image = ph1_neut.png
