Hi,
I'm want to be sure to detect 5way navigator with the correct version, but
there is
so many way to detect it, what is the good one and teh difference between :
FtrGet(navFtrCreator, navFtrVersion, &version);
FtrGet(sysFtrCreator, sysFtrNumFiveWayNavVersion, &version)
FtrGet(hsFtrCreator, hsFtrIDNavigationSupported, &version)
Do I need to the those three requests ?
I use :
if (!FtrGet(hsFtrCreator, hsFtrIDNavigationSupported, &version)) {
if (version >= 2)
OPTIONS_SET(kOpt5WayNavigatorV2);
} else if (!FtrGet(sysFtrCreator, sysFtrNumFiveWayNavVersion,
&version)) {
if (version >= 1) // why 1 ?
OPTIONS_SET(kOpt5WayNavigatorV2);
} else if (!FtrGet(navFtrCreator, navFtrVersion, &version)) {
if (version >= 1)
OPTIONS_SET(kOpt5WayNavigatorV1);
}
Hi Chris,
don't know about hsFtrIDNavigationSupported and
sysFtrNumFiveWayNavVersion but navFtrVersion is the old PalmOne style
used on older Tungstens and Zire models. It is quite important to catch
this then you now you have to wait for PageUp/Down and
NavLeft/Right/Select as described in the PalmOne 5Way SDK. You can also
assume that everything else has either a valid Rocker implementation:
look for PageUP/Down and RockerLeft/Right/Select or doesn't have a 5-way
at all. Then you can only see PageUp/Down and HardButtons. The
HardButtons could be only 2. It's the question if it is usefull to
support such devices in the first case. I usually check for
* navFtrVersion to use NavChange stuff
* TapwaveSDK to use the Function and Trigger buttons
* default: see the Rocker devices above.
Regards
Henk
