示例1: DispatchMouseOverOut
void EventDispatcher::DispatchMouseOverOut(Widget *target, const Point &mousePos)
{
// do over/out handling for wherever the mouse is right now
if (target != m_lastMouseOverTarget.Get() || target->IsDisabled()) {
if (m_lastMouseOverTarget) {
// if we're switching from float to non-float then we need to force the out event, even if the mouse is still over the last target.
// only the base widget of a floating stack is marked floating, so walk up to find it
// XXX this is doing too much work. should we flag this on the widget somewhere?
Widget *targetBase = target;
while (!targetBase->IsFloating() && targetBase->GetContainer()) targetBase = targetBase->GetContainer();
Widget *lastTargetBase = m_lastMouseOverTarget.Get();
while (!lastTargetBase->IsFloating() && lastTargetBase->GetContainer()) lastTargetBase = lastTargetBase->GetContainer();
// if we're moving from float->non-float or non-float->float,
// or the two targets don't have the same base (eg one just got
// removed from the context in whole ui switch)
// force the out event on the last target by reporting a position
// that is by definition outside itself
const Point outPos =
(targetBase->IsFloating() != lastTargetBase->IsFloating() || targetBase != lastTargetBase) ? Point(-INT_MAX) : mousePos-m_lastMouseOverTarget->GetAbsolutePosition();
m_lastMouseOverTarget->TriggerMouseOut(outPos);
}
if (target->IsDisabled())
m_lastMouseOverTarget.Reset(0);
else {
m_lastMouseOverTarget.Reset(target);
m_lastMouseOverTarget->TriggerMouseOver(mousePos-m_lastMouseOverTarget->GetAbsolutePosition());
}
}
}示例2: IsOnTopLayer
bool Widget::IsOnTopLayer() const
{
const Layer *topLayer = GetContext()->GetTopLayer();
Widget *scan = GetContainer();
while (scan) {
if (scan == topLayer)
return true;
scan = scan->GetContainer();
}
return false;
