触发事件并不是很复杂的事情，
TKeyResponse CXXContainer::OfferKeyEventL(const TKeyEvent& aKeyEvent, TEventCode aType)
{
TInt code = aKeyEvent.iCode;
switch(code)
{
// is navigator button pressed
case EKeyOK:
{
// pass the key press event to view,
// then view will pass it to ui class's handler
iXXView->ProcessListEvent(iListBox->CurrentItemIndex()) ;
}
return (EKeyWasConsumed);
case EKeyLeftArrow :
case EKeyRightArrow :
return (EKeyWasConsumed);
default:
// Let Listbox take care of its key handling
return iListBox->OfferKeyEventL(aKeyEvent, aType) ;
}
}
这个iXXView的ProcessListEvent()函数就是传入当前用户选择的那个list item的index。 |
