Obtain and Enter Icon Properties

An icon in the context of the Emulator is any graphic, constant or variable, that is
displayed on the device screen global region (the region that is outside of the
drawable area). This includes scrolling indicators, the battery level indicator and
any other images of a similar type. See

Appendix A, “Default Emulator Device

Property Files

” for a list of the icons provided with the J2ME Wireless Toolkit.

named states, as long as it has a line in the property file for each state giving the
image associated with that state. If no image file is given for a particular state
then no image is displayed when the icon is in that state.

another, enabling a smooth visual transition on a change of state.
