Qwidget transparency is not coming for my application
System: Embedded linux
Kernel Version: Linux 4.4.
My application needs to create a single qwidget with background color:blue, with a 15% transparency.
I used Qt interface setWindowOpacity(0.85); it works good with windows platform but it draws a complete opaque widget in my linux machine. (both in Qt4.8 and Qt5.0)
I also tried with below options.
- setStyleSheet("background-color: rgba( 23, 29, 35, 85%)"); it is working while using Qt4.8, but not working for Qt5.0
- setAttribute(Qt::WA_TranslucentBackground); it gives complete transparency in my linux machine, not working for windows.
- Also tried to overload paintEvent and setting the alpha.
I could not understand why transparency of widget is not working for Qt5.0, although i tried to mention RGBA explicitly for my widget.
Can anybody help me resolving this issue.

Is this a gfx card driver/limitation under Linux/embedded?
Forget about transculency on embedded linux. Your X server there probably doesn't support compositing anyway.
so it is not possible to get translucency on embedded linux anyway?
Thanks JonB for your reply, I am checking my x-server side for this issue.
@JonB : The issue was caused by our wayland compositor (window manager) of embedded system.
