Hi @Sandy.Dahl,
You can get around this, but at some point whether something is a button click or the beginning of a drag or swipe is not something TouchGFX can detect - This is probably something that needs to be handled through UI design. What you can do, though, is to override the handleClick/Drag event methods of your view and evaluate what to do. You can then forward events to the view itself (to be automatically handled, as usual), or send events to concrete widgets manually.
But i'm not totally clear on what you're trying to achieve here. Just to show you part of what we're talking about here, imagine a swipe container with buttons inside. The nature of the swipe container is to react to click and drag, which means that elements inside (Like buttons, or even a smaller swipe container) will not receive anything. For the sake of being pendantic, we're just evaluating a single button, myButton inside a SwipeContainer, myContainer.
void MyView::handleClickEvent(const ClickEvent& evt)
{
// The recipient of the initial touch is impossible to determine. Are we trying to drag but accidentally started on the same position as a button? Logic dictates that we're trying to press the button, so check for intersection and issue event manually.
if(myButton.getRect().intersect(evt.getX(), evt.getY()) && evt.getType() == ClickEvent::PRESSED)
{
myButton.handleClickEvent(evt);
}
else
{
mySwipeContainer.handleClickEvent(evt);
}
// && no longer intersects OR the swipe container is swiping. What should the functionality be? If you're dragging but are within the button rect, should it receive a release event to trigger a callback or not?
if (wasDragging && evt.getType() == ClickEvent::RELEASED)
{
//In this casesend a cancel event. we do not want the button to send a released event
myButton.handleClickEvent(ClickEvent(ClickEvent::CANCEL, 0, 0));
}
}
void MyView::handleDragEvent(const DragEvent& evt)
{
//Here if we start dragging, we should send a CANCEL event to the currently PRESSED item, and start dragging the swipecontainer.
mySwipeContainer.handleDragEvent(evt);
}
