Detecting if popups are blocked?

[user316]

Hi,

Is there any way within the SmartGWT framework to detect if the user's browser has blocked popups, when they try to open a new tab when clicking on a button/link inside of SmartGWT?

No,we don't provide a built-in function to detect pop-up blocking. By googling a bit you can find lots of advice and approaches.

Thanks, I ended up using a JSNI approach. This is my code in case anyone else could find it useful:

public native static boolean openPopupAndCheckBlocker(String url) /*-{

        var popupBlockerChecker = {
            check: function(popup_window){
                var _scope = this;
                if (popup_window) {
                    if(/chrome/.test(navigator.userAgent.toLowerCase())){
                        setTimeout(function () {
                            _scope._is_popup_blocked(_scope, popup_window);
                         },200);
                    }else{
                        popup_window.onload = function () {
                            _scope._is_popup_blocked(_scope, popup_window);
                        };
                    }
                }else{
                    _scope._displayError();
                }
            },
            _is_popup_blocked: function(scope, popup_window){
                if ((popup_window.innerHeight > 0)==false){ scope._displayError(); }
            },
            _displayError: function(){
                alert("Popup Blocker is enabled! Please add this site to your exception list.");
            }
        };
        var popup = window.open(url, '_blank');
        popupBlockerChecker.check(popup);
        return;
    }-*/;
