Operating the MC909X 2 - 29
Alpha/Application
These keys can have an application assigned to the function value and have an alpha
value assigned when used with the ALPHA function key.
On Windows Mobile 5.0 devices: F6
and
F7
keys cannot be remapped and are
dedicated by the Operating System to control volume level. When these keys are
pressed, Shell.exe traps them and displays the volume adjustment window. To get these
keys to an application, call GXOpenInput() at the beginning of the application and call
GXCloseInput() at the end of the application. This redirects all of the key events to an
application, including the
F6
and
F7
keys.
Note:
Other applications cannot receive any key event until GXCloseInput() is called.
For example, if the customer is using the APP1 key to run Calc.exe, this is disabled
during this period.
