Note – This type of font supports only eight bit ASCII values (256 characters) and not 16 bit unicode characters.

Font Underlining

The MIDP specification allows underlined fonts. By default, the emulator supports font underlining. You can disable this feature for all fonts by setting the property:

font.all.underline.enabled = false

It is also possible to disable underlining for a specific font by setting the property:

font.<face>.<style>.<size>.underline.enabled = false

Where face, style and size are as described in “Fonts Used by the MIDP APIs” on page 19.

It is possible to specify the thickness of the line used for underlining by a line of the form:

font.<face>.<style>.<size>.underline.width = <width in pixels>

The default width of the line is one pixel for plain and italic font styles and two pixels for the bold font style.

It is also possible to specify the distance of the line used for underlining from the font baseline by a line of the form:

font.<face>.<style>.<size>.underline.offset = <offset from baseline in pixels>

The default offset is one pixel for all fonts.

The Device Image

To specify the device image, you need to specify three separate device graphic images. These image files should differ only in their representation of active buttons (those buttons that are to be used in the emulation of the device in the J2ME Wireless Toolkit).

The image files are:

A base image with all active buttons in a neutral state (not pressed or highlighted)
