Browser execute function in child window [message #465212]

I have good results from using Browser.execute as a means
to communicate with the embedded browser instance [Windows/IE],
but I am not doing so well in attempting to do the same with
a pop-up from the embedded instance. I would appreciate either
of these types of help:

a. Examples of successful invocation of anything like:

browser.execute ("someFunction();");

where someFunction, at some point does: childWindow = window.open();

browser.execute ("childWindow.someFunction();");

b. Advice on debug/trace method that might help in determining where
the breakdown occurs. IE, as you know, doesn't give me any decent
debug assistance as would Firefox, and hours of trying everything I
can think of has not resulted in any progress.

Thank you.

See:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet173.java?rev=HEAD& amp;content-type=text/vnd.viewcvs-markup

In the OpenWindowListener.open callback you can create your own shell and
Browser widget to manage the new window. Then you can call execute on the
new instance of Browser jsut like you did for the parent instance.

Veronika,

Thank you. I know I can do what you suggest, but the
result is not truly the same as there would not then be
any communication between the parent and the child, unless
I 'wired' that through the Browser status event mechanism.

While your work-around is quite reasonable, should my
problem be submitted as a bug to be worked on? I believe
that the Browser OLE implementation has either an
incompatibility or an outright defect. Whether your answer
to my question is 'yes' or 'no', if you can give me any
guidance on how to trace/debug the failure, I want to see
if I can help define what is broken. It would really be
desirable to have a single Browser instance that could
pop-up children as required AND for the rich client to be
able to communicate with the script engine in that child
with the same facility that we can now communicate with the
script engine in the parent.

Thank you.

You should enter a feature request for this against Eclipse Platform SWT.
