Do you have an idea how can I set that parameter ?

popups: I thought that would not be interesting anyhow for a RIA application embedded(enriched) in lazarus.

Will look into it. Can you give a sample site to test it. I am not an expert in popup technology, maybe there are many types.

With this line in the demo
QWebPage_setLinkDelegationPolicy(QWebView_Page(WebView.Handle),QWebPageDelegateAllLinks); i convert requests to open a new window(or tab) into a signal handled by pascal. I handle these requests by opening in the same window. So this way I let anchors with target attribute _blank open in the same window.
