A very good reference for programmers require to track the sliding event for N95 device. It provides the key event code to look for in order to track the slider event.

The Nokia N95's slider sends the following key events:

(1) Open keyboard slider
aType = 0x0003, iCode = 0x0000, iScanCode = 0x00ac  (EStdKeyDevice8)
aType = 0x0002, iCode = 0x0000, iScanCode = 0x00ac
 
(2) Close keyboard slider
aType = 0x0003, iCode = 0x0000, iScanCode = 0x00ad  (EStdKeyDevice9)
aType = 0x0002, iCode = 0x0000, iScanCode = 0x00ad
 
(3) Open music slider
aType = 0x0003, iCode = 0x0000, iScanCode = 0x00a8  (EStdKeyDevice4)
aType = 0x0002, iCode = 0x0000, iScanCode = 0x00a8
 
(4) Close music slider
aType = 0x0003, iCode = 0x0000, iScanCode = 0x00a9  (EStdKeyDevice5)
aType = 0x0002, iCode = 0x0000, iScanCode = 0x00a9

Take care! In the S60 SDK (eikon.hrh), there are some helpful ids defined:

#define EKeyGripOpen EKeyDevice4
#define EKeyGripClose EKeyDevice5
#define EKeyTwistOpen EKeyDevice8
#define EKeyTwistClose EKeyDevice9

But they do not help. There is never a iCode sent. The slider only sends iScanCode events. There is no EStdKeyGripOpen defined, so you have to put the generic defines from Symbian into your code.
