@Neku Please tell us what problem you have, not just posting big amount of code without saying what actually does not work...

[Neku]

Sometimes After Pressing Mouse Button it doesn't released Button doesn't come back to its original color same thing happening with mouse hover also

[SGaist]

Hi,

That does not help much more.

You need to provide a clear explanation about what you do, what is happening and what you expect.

Also, reduce your code to the bare minimal so you can provide a minimal compilable example.

Also, post your code between coding tags, that will make it readable unlike the first post in this thread (you can edit it to fix it).

About that code, beside some Qt types here and there, it looks like you either are using some native functionality or some other framework. That's the kind of stuff that you should explain.

[Neku]

I have different tabs button when I press on them or hover on them it is not getting released sometime.

[SGaist]

As already requested, provide a minimal compilable example that shows your issue.

Nobody can help you with the small amount of information you gave.

code for mousepress
bool EventHandler::handleMousePressEvent(QPointF pos, Qt::MouseButton mouseButton)
{
std::shared_ptr<EventInfo> pEventInfo = nullptr;

m_bMousePressed = true;

// Used incase of mouseMove event, to trigger Up event when the mouse pressed is moved outside screen item boundary.

[SGaist]

Can you please provide what was requested and not some snippet of code from your application ?

[Neku]

Problem is after pressing Mouse Button on a Button sometimes it is not releasing it should released

[SGaist]

Do you realize that we are running in circles ?

I have already asked you several time to provide a minimal compilable example that shows your issue.

[Neku]

void DFQuickItem::hoverEnterEvent(QHoverEvent* pEvent)
{
if ((pEvent == nullptr) || (nullptr == m_pEventHandler))
{
TRACE_OUT_F(F::INFO, _M("pEvent or m_pEventHandler is nullptr "));
return;
}

if (!m_pEventHandler->handleHoverEnterEvent(pEvent->pos()))
{

    TRACE_OUT_F(F::INFO, _M("hoverEnter Event is not present for Rete element "
                            "at position x: %1 y: %2")
                             << pEvent->pos().x() << pEvent->pos().y());
}

}
