Obtain the input method status of Symbian

It is best to use makneditingstateindicator to obtain the input method status. After keyup and keydown, obtain the input method status. The Code is as follows:

Makneditingstateindicator * Ei = caknenv: static ()-> editingstateindicator ();
If (! EI) return eunknown;

Caknindicatorcontainer * Ic = EI-> indicatorcontainer ();
If (! Ic) return eunknown;

If (IC-> indicatorstate (s_uid (eaknnavipaneeditorindicatorpinyin )))
{
// To do... if input method = T9 (pinyin and strokes)
}
If (IC-> indicatorstate (s_uid (eaknnavipaneeditorindicatorstroke )))
{
// To do... if input method = T9 (pinyin and strokes)
}
Else if (IC-> indicatorstate (s_uid (eaknnavipaneeditorindicatorlowercase )))
{
// To do... if input method = "ABC ";
}
Else if (IC-> indicatorstate (s_uid (eaknnavipaneeditorindicatoruppercase )))
{
// To do... if input method = "ABC ";
}
Else if (IC-> indicatorstate (s_uid (eaknnavipaneeditorindicatortextcase )))
{
// To do... if input method = "ABC ";
}
Else if (IC-> indicatorstate (s_uid (eaknnavipaneeditorindicatornumbercase )))
{
// To do... if input method = "123 ";
}
Return eunknown;
