QWebView opacity rendering trouble
-
Hi eveybody,
I have a strange problem with opacity in a webview.
I am using a QWebView in front of a QGLWidget.
The background of the QWebView is set to transparent, like this :
this->setStyleSheet("background-color: transparent;"); this->setWindowFlags(Qt::FramelessWindowHint); //No windowing this->setAttribute(Qt::WA_TranslucentBackground); // No background
And the background of the HTML page is also set to transparent in the CSS of the page, like this :
body{ background-color: rgba(255,255,255, 0) !important; background:transparent !important; }
I want to create a DIV on the left of the HTML page with a white background at 60% opacity, like this:
the CSS property in the HTML page :background: rgba(255, 255, 255, 0.60);
Normaly the result should be like this :
Under Chrome
(a small white transparency)But
When I am running the program, here the result I've got :
In the app
(an ugly gray transparency)I have tried w/o any success, this :
QPalette palette = this->palette(); //Get webView palette palette.setBrush(QPalette::Base, Qt::transparent); this->page()->setPalette(palette); //Set transparent palette this->setAutoFillBackground(false); this->setAttribute(Qt::WA_OpaquePaintEvent, false);//Remove opaque
I really don't know how to handle this issue : (
Please Can anyone help me on this ?

try to set alpha value 0-255.
ex: rgba(255, 255, 255, 102) instead of rgba(255, 255, 255, 0.60);

@B.-Marley No working cause it's not valid, css3 only accept alpha value between 0 and 1
I also tried hsla() property but same problem.
So I thought "ok whatever, I'll put a white background-image 1px repeating with a opacity of 0.6."
It's not working too. Same result.
So now I'm coming back to my first idea that this issue is from QWidget layering background.
The 3D widget is a QOpenGLWidget and I have my QWebview in front with the properties :this->setStyleSheet("background-color: transparent;"); this->setAttribute(Qt::WA_TranslucentBackground); // No background
Maybe the idea of :
this->setAttribute(Qt::WA_OpaquePaintEvent, false);//Remove opaque
was a good way ?
There is anyway to repaint the background or something else ?
Please help

Can it be a sort of filter on the QOpenGlWidget ?
