Virtual Keyboard no clicked(bool) signal emited

Hi,
I got strange problem.
Im during implementation of virtual keyboard and found strange issue. When I use my keyboard via mouse everything is ok, but when I try to work by touch screen I noticed that sometimes QPushButton::clicked(bool) signal is not emitted. Especially when button is pressed a bit longer. As I checked QpushButton::releaseEvent() is also not emmited.

Any ideas?

Best regards,
Tomek

Hi,

What version of Qt ? On what OS ?

Sounds like a "Click and hold" scenario, isn't it ?

"Click and hold" scenerio? Could You be more specific?

Windows 10 Qt 5.5.0

Sorry, I meant Tap and Hold. Meaning a long tap gesture i.e. you keep your finger on the screen longer.

For the most part you're right (if I hold long those event never occures), but it also happens when I just click(sometimes).

As I checked currently it's not possible to use press and hold functionality on QPushButtons on Windows 10 with touch screen. With mouse everything works fine.
