Zoom In and Zoom Out Modes
The Motorola T720 supports zoom in and zoom out modes on the display. When zoom in
mode is selected, the display area is enlarged, reducing the number of visible pixels on
the display. The zoom mode is controlled by a user selectable option but is often preset
by region distributors. For example, in Asia, zoom in mode is the default setting, whereas
in the US, zoom out is the default setting.
Developers should note which region they are writing the program for and adjust the
program’s UI accordingly to fit. Just as important, you should test the program under both
zoom conditions to ensure no clipping of the visible portions of the program occur.
If your program requires the use of one zoom mode over another, it should read and store
the current zoom setting, change it as required during execution, and always restore the
original zoom zetting upon exit.
Softkey Character Limits
The softkey area at the bottom of the display is divided into three equal sections of
approximately 40 pixels each. Any text that appears as a softkey selection must fit within
that 40-pixel limit. This limits the number of characters you can use in a softkey to a
maximum of six characters per softkey. Failure to follow this guideline can result in clipped
softkey text displays.
