Hi list. We need to embed a web browser inside our application, so we
loaded the COM parcels to use IE. Our task is actually very basic: when
the user clicks a link, we check a bunch of things and then decide if
the navigation should proceed or not. In order to do so we decided to
use the event:
beforeNavigate2:url:flags:targetFrameName:postData:headers:cancel:
So basically we have:
postOpenWith: aBuilder
super postOpenWith: aBuilder.
(aBuilder componentAt: #WebBrowser) widget comComponent
when:#beforeNavigate2:url:flags:targetFrameName:postData:headers:cancel:
evaluate: [:p1 :p2 :p3 :p4 :p5 :p6 :p7| self preProcessURL: p2].
So far, so good. Now the problem arises when we need to stop the
navigation started by the user. We tried to set the Cancel parameter of
the event (:p7) and to explicitly stop the navigation by calling the
stop method of the browser[*], but none of those work. As a matter of
fact, the following code makes no changes at all, when I would expect to
cancel any navigation started by clicking on a link:
postOpenWith: aBuilder
super postOpenWith: aBuilder.
(aBuilder componentAt: #WebBrowser) widget comComponent
when:#beforeNavigate2:url:flags:targetFrameName:postData:headers:cancel:
evaluate: [:p1 :p2 :p3 :p4 :p5 :p6 :p7|
p7 value: true.
(aBuilder componentAt: #WebBrowser) widget comComponent stop].
Am I missing something? Did anybody experience something like this before?
I would also really appreciate if someone has had any experiences in
embedding firefox instead of IE, both in windows and/or in linux.
Thanks in advance,
Andrés
[*] The stop method was missing in the WebBrowser class. The code we
added is:
stop
self testDefaultInterface.
^self defaultInterface stop.
