when the console open it shows some data that shown in the console in debug mode and I guess the problem is from using QWebEngine the console show me this data that come from the website loaded in QWebEngineView the data always start with JS: like this

js: Phaser.Cache.isSoundDecoded: Key "dealer_12" not found in Cache.
[5684:3840:0731/214213.208:INFO:CONSOLE(27)] "Phaser.Cache.isSoundDecoded: Key "loose" not found in Cache.", source: example/libs.js (27)

this is some of the data appears in the console so the question is how can I make this console not appear when I start my application? I don't know what makes this problem and don't know what should I search for?

@AmrCoder It's a javascript info message (warning/error?). It is coming from the web page you are loading with QWebEngine. You can fix the js code if it's something you own, or you can just ignore it if it is something someone else made.

Edit: I read further and noticed it was pulling up a console that you don't want. I don't know how to suppress that but I will check the docs real quick and see if anything jumps out.

Edit again: Here ya go this should help you in preventing the console popping up. http://doc.qt.io/qt-5/qtwebengine-debugging.html#console-logging. It looks pretty easy to deal with. You just catch the messages and deal with them how you like rather than letting the console come up.
