Hi all
I'm encountering a "Stop this script execution?" alert message with
Internet Explorer, not when executing and using my application, but on
closing it (i.e. by quiting the page or refreshing). My application is
indeed quite big in terms of GUI (many tabviews containing
qx.ui.table.Table components that I customized, commands, menuBar and
toolBar, etc), but I really don't know how to fix this...
First, I admit I'm not good at all at writing "destructors" for all my
qooxdoo classes : can it have any influence on the page closing down
speed? Second, I did not add any code in the close() or terminate()
functions of my Application, so all this code called at closing
time is
called by the framework, not by me. Is there a way to disable this? I
know it's not a good idea, but the IE support is unfortunately quite
important for my customers, and I would prefer the application to
leave
a huge memory footprint in the browser than triggering this ugly
javascript alert message and preventing a user from closing his
browser.
Sigh. Yet more IE speed issue. I imagine that your application is
QUITE large if destruction is taking that incredibly long.
You might consider using the close() method and doing some of the
destruction progressively using qx.ui.progressive.Progressive and its
FunctionCaller renderer. An example of using that is in the demobrowser:
http://demo.qooxdoo.org/devel/demobrowser/index.html#progressive~ProgressiveLoader.html
<http://demo.qooxdoo.org/devel/demobrowser/index.html#progressive%7EProgressiveLoader.html>
Although this demo is showing Progressive and the FunctionCaller
renderer being used as a progressive loader, it can just as easily be
used as a progressive unloader. Your difficulty will be in figuring
out what and in what order to destroy. That task, however, is left as
an exercise for the reader. :-)
Cheers,
Derrell
