The function examines what type of key was pressed: for UIQ, the hardware navigation and
CONFIRM keys have special key codes that I test for here. The navigation keys result in the
cursor being moved, and the board redrawn to show the new cursor position. A CONFIRM
key event indicates the user shooting at a square. If the square has been shot at before
(IsKnown() is true), then it calls the controller's ViewCmdHitFleet() function so that the
hit request can be processed.
Similarly, the view receives pointer events by implementing the CCoeControl base class
function HandlePointerEventL().
void CFleetView::HandlePointerEventL(const TPointerEvent&
aPointerEvent)
}
{
// check whether we're interested
if (
else
}
aPointerEvent.iType==TPointerEvent::EButton1Down &&
iBoardRect.Contains(aPointerEvent.iPosition)
)
{
// identify the tile that was hit
TInt x=(aPointerEvent.iPosition.iX-iBoardRect.iTl.iX)/
iTileSize;
TInt y=(aPointerEvent.iPosition.iY-iBoardRect.iTl.iY)/
iTileSize;
// move cursor if necessary
TBool iCursorMoved=(x!=iCursorX || y!=iCursorY);
SetCursor(x,y);
// hit square unless it's already known
if (iFleet->IsKnown(x,y))
{
iEikonEnv->InfoMsg(R_GAME_ALREADY_KNOWN);
if (iCursorMoved)
}
DrawTilesNow();
iCmdHandler->ViewCmdHitFleet(x,y);
The function responds to a tap on a screen (a TPointerEvent::EButton1Down event)
by translating the event's x and y coordinates into the coordinates of the relevant square on
