Hello all,
We are developing quite a complicated application in Laszlo, and I
am facing a problem now.
I am trying to implement something like a 'hourglass cursor' to
indicate to the user that the program is working. Initally I tried
to do it using LzCursor methods - but the cursor just disappeared
when some lengthy operation was in progress. So I decided to use
statusline (I have one being essentially several <text>'s in the
bottom), and tried to do like
lockEvents();
do_something_heavy_and_lengthy();
unlockEvents();
where lockEvents just made my statusline display 'BUSY', and
unlockEvents made converted it back to 'Ready'.
The problem is that looks like things are happening in parallel:
- lockEvents() starts changing the text
- while it is working, something heavy starts and blocks everything
- when something heavy is done, lockEvents() is finished and is
immediately followed by unlock making all the stuff completely
useless: 'busy' appears for a moment AFTER the operation has been
performed.
So
(1) am I right that this strange stuff ('busy' appearing after long
operation) is because of parallel execution?
(2) can I do anything with that?
