Hi,
I haven't heard of this before. All js execution is managed by the
underlying native browser, so it's possible that this would work in some
implementations but not in others, due to either a bug or a design
difference.
One possible workaround you can try is to do your execute()s in an
asyncExec(...) block so that they're run when the event queue is idle (which
_may_ indicate that the fade has completed). I'm not sure if this will
help, but if you want to try it, do your execute() like:
browser.getDisplay().asyncExec(new Runnable() {
public void run() {
if (browser.isDisposed()) return;
browser.execute(...);
}
});
If this does not help then it's hard to know what's happening here or if it
can be worked around without a test case. It would also be helpful to know
if it happens in the different native browser implementations (eg.- on
Windows the Browser embeds IE, on Linux it embeds either gecko/mozilla or
webkitgtk, etc.). If you're able to reduce your case to a small case that
reproduces the problem (ideal template:
http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org. eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet148 .java )
then please log a report with swt at
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Platform &component=SWT .
