Here is a way to show an icon on the IndicatorPane of Series 60. You can show an icone near to the battery pane or signal pane, for that you have to customise the code.
I’ve used a calss named CIndicatorIcon derived from CCoeControl. Now you have to create the ConstructL() should be like this:
void CIndicatorIcon::ConstructL()
{
iMyWindowGroup = RWindowGroup(iCoeEnv->WsSession());
User::LeaveIfError(iMyWindowGroup.Construct((TUint32)&iMyWindowGroup));
iMyWindowGroup.SetOrdinalPosition(0, ECoeWinPriorityAlwaysAtFront);
iMyWindowGroup.EnableReceiptOfFocus(EFalse);
CreateWindowL(&iMyWindowGroup);
// by default setting the indicator icon to inactive
SetIndicatorIconL(EIndicatorIconAppActive);
ActivateL();
}
In the ConstructL() I was calling another function called SetIndicatorIconL(), to set the icon:
void CIndicatorIcon::SetIndicatorIconL(TIndicatorIcon aIndicatorIconType, TBool aRedraw)
{
switch(aIndicatorIconType)
{
case EIndicatorIconEmpty:
iIndicator = CEikonEnv::Static()->CreateBitmapL(KSysIconFile, EMbmAvkonQgn_prop_empty);
iIndicatorMask = CEikonEnv::Static()->CreateBitmapL(KSysIconFile, EMbmAvkonQgn_prop_empty_mask);
break;
case EIndicatorIconAppActive:
iIndicator = CEikonEnv::Static()->CreateBitmapL(KSysIconFile, EMbmAvkonQgn_bt_connect_on);
iIndicatorMask = CEikonEnv::Static()->CreateBitmapL(KSysIconFile, EMbmAvkonQgn_bt_connect_on_mask);
break;
case EIndicatorIconAppInactive:
iIndicator = CEikonEnv::Static()->CreateBitmapL(KSysIconFile, EMbmAvkonQgn_prop_bt_audio);
iIndicatorMask = CEikonEnv::Static()->CreateBitmapL(KSysIconFile, EMbmAvkonQgn_prop_bt_audio_mask);
break;
default:
break;
}
SetRect(TRect(TPoint(KIndicatorPosX, KIndicatorPosY),iIndicator->SizeInPixels()));
// if aRedraw == ETrue just draw the canvas again.
if(aRedraw)
{
DrawNow();
}
}
You have to over-ride Draw() from CCoeControl. The Draw function is as follows:
void CIndicatorIcon::Draw(const TRect& aRect) const
{
CWindowGc& gc = SystemGc();
gc.Clear();
gc.SetBrushStyle(CGraphicsContext::ENullBrush);
gc.BitBltMasked(TPoint(aRect.iTl.iX, aRect.iTl.iY),
iIndicator,
TRect(TPoint(0, 0), iIndicator->SizeInPixels()),
iIndicatorMask,
ETrue);
}
Now add these lines to the ConstructL() of your Application’s AppUi class:
iIndicatorIcon = CIndicatorIcon::NewL();
// The next line will set the icon to draw and it'll draw to the screen.
iIndicatorIcon->SetIndicatorIconL(CIndicatorIcon::EIndicatorIconAppInactive, ETrue);
