This plugin does not support setting window opacity

IL

Hi all,
I am trying to use opacity animation on my beagle bone like target, when I am running the code I am getting the above message
"This plugin does not support setting window opacity"
I have tried to search that on the WEB but I didn’t find any related issue.
Can anyone tell me what the missing plugin for my target is? (On my fedora it's working great!)

Best regards,
IL

//Summery of my code is
MainWindow::MainWindow(QWidget *parent)
{
    QPropertyAnimation *animation;
    animation = new QPropertyAnimation (myWidgetPage, "windowOpacity", this);
    animation->setStartValue(0.0);
    animation->setEndValue(1.0);
    animation->setDuration(2000);
   ...
}

void MainWindow::startAnimation()
{
    animation->start();
}

Hi,

It's not a problem of missing plugin. This message just tells you that the plugin you are using doesn't provide that feature.

Hi and thanks for replaying,
Anything I can do to change it and support opacity?

I am not sure if you can apply stylesheet to your animation object, but in my app i applied opacity with background:rgba(0-256, 0-256, 0-256, 0-1 (opacity))

Hello,
I want my window to appear after action and disappear slowly using window opacity, actually currently I am implement volume bar window that when changing the volume the volume bar appear and after 3 seconds it start to disappear.
I assume that if you are using stylesheet opacity so you probably holding fix window opacity, am I correct?

Thanks,
IL

You should give more details about the device and Qt backend you are using.
