connect( this->page(), &QWebEngineView::loadFinished(), this, OnPopulateJavaScriptObjects() );

I have a class WebView which is where void OnPopulateJavaScriptObjects is declared and implemented .. all functions in one file. so when I am trying to call this function I am getting this error

/home/poker/QTwrapper/main.cpp:40: error: no matching function for call to ‘WebView::loadFinished()’
         connect( this->page(), &QWebEngineView::loadFinished(), this, OnPopulateJavaScriptObjects() );

AND SO ON... So i know I have a lot of mistakes here... who can help me to explain my mistakes and what can be here the best solution to run this piece of code.

when I am writing connect( this->page(), &QWebEngineView::loadFinished, this, OnPopulateJavaScriptObjects() ); I am getting 

/home/poker/QTwrapper/main.cpp:40: error: invalid use of void expression connect( this->page(), &QWebEngineView::loadFinished, this, OnPopulateJavaScriptObjects() );

Replace

connect( this->page(), &QWebEngineView::loadFinished(), this, OnPopulateJavaScriptObjects() );

with

connect( this->page(), &QWebEngineView::loadFinished, this, &OnPopulateJavaScriptObjects );

with () you call a method. When you want its address, do call it.
