G’day
I’ve got a scrolling progress indicator that’s not actually scrolling as it lengthens. The blue diamonds are fixed, and not moving as they should.
Does anyone have any idea how to get it to animate please? The ‘usesThreadedAnimation’ doesn’t work.
Regards
Santa
Progress's usesThreadedAnimation(true)
Progress's incrementBy_(1)
Progress's displayIfNeeded()
Get rid of the usesThreadedAnimation (which should be usesThreadedAnimation_ to work), and get rid of displayIfNeeded.
G’day Shane, & thanks
Unfortunately ‘Progress’s incrementBy_(1)’ didn’t work on it’s own; in order to get the indicator to work it needs updating with ‘displayIfNeeded’, and in order to get it to animate it needed the ‘setUsesThreadedAnimation’ line below. Without them there’s only a sudden update when the script finishes.

on UpDateProgress(incP)
repeat incP times
Progress's setUsesThreadedAnimation_(true)
Progress's incrementBy_(1)
Progress's displayIfNeeded()
end repeat
end UpDateProgress
That suggests your problem is actually elsewhere.
Let me guess: you have a handler triggered by a button, and the attempt to update is happening in that handler, yes?
I would log the start and end of the handler (or more) to check.
G’day Shane
GREAT guess! (estimation)
I’ve got 6 checkboxes that determine if certain reports on data bases are sent, and the code is called by a button that stays blue until the code is finished.

And that’s your real problem. When you push the button, the event is sent to your handler, and the button isn’t released until the handler is finished – meanwhile your dialog is blocked. If you look at the first example here http://www.scriptingmatters.com/ASObjC, you’ll see the same thing, and the solution.
G’day again Shane.
I’ve followed the tutorial, and struck a problem. I can’t for the life of me work out how you bind the ‘isidle’ to the Referencing Bindings.
I don’t even have a group called ‘Referencing Bindings’ to try and work with.
I’ve scoured the net but can’t find a tutorial that explains how to go about creating the bindings.
Can you advise please?
Regards
Santa
It’s OK, I figured it out.
However, I still need to use the following, presumably because I’m triggering the routine from within handler loops.
It gives a nice smooth action, whereas without the line ‘displayIfNeeded’ it is very jerky.
BUT, the button is no longer blue.
on UpDateProgress(incP)
repeat incP times
Progress's setUsesThreadedAnimation_(true)
Progress's incrementBy_(1)
Progress's displayIfNeeded()
end repeat
end UpDateProgress
Oops, I posted too soon. Turns out that the routine only works once, then on subsequent runs refuses to draw as all.
I had the progress indicator set to hide when not drawing, so set it to visible. Now it won’t even draw the first time.
I removed the line ‘Progress’s setUsesThreadedAnimation_(true)’ and it works, but doesn’t animate.
I’ve tried binding the indicator to the Animate setting, bound to a true property, but still no animation.
Anybody got any ideas on what to do please. The scrolling looks pitiful when it’s not animated.
Regards
Santa
You do it in Interface Builder, in the Bindings panel of the Inspector.
But it’s not bindings or lack of it that is your problem; it’s the need to use performSelector_withObject_afterDelay_ so that your handler can return quickly. Doing that will solve the problem that setUsesThreadedAnimation_ and displayIfNeeded cannot.
G’day Shane
I’ve worked out how to bind to ‘isIdle’, and I’ve included the performSelector_withObject_afterDelay_ handler, but I still needed the ‘displayIfNeeded’ to give a smooth animation, otherwise it ‘jerked’ from one position to the next, in large increments.
However it doesn’t animate. I see in the connections inspector a ‘startAnimation’ but can’t figure out how to use it. Is it required?
I’ve bound the ‘Animate’ to a property set to true, but it’s still not animating.
Regards
Santa
That’s the way it works: you tell it to be a number, and a number it is. If you want finer steps, you need to use a bigger range of numbers. The animation stuff you’re playing with is for indeterminate progress bars, not ones where you set the value.
G’day Shane
That’s what I’m doing, but I’m calling the small incrementing routine from within loops, and even though I’m using large numbers, it still jerks from the number at the beginning of the loop, to the number at the end, unless I use the ‘displayIfNeeded’.
I’ll attach a part of my script so you can see one loop that calls it for hundreds of times ( don’t ask why).
Of more importance to me atm is why isn’t it animating?
How on earth do I bind the startAnimation to the progress indicator?

You’re not listening: you don’t. startAnimation is for indeterminate progress bars.
You seem to be doing a lot of incrementing – what have you set as the bar’s maximum value?
Ummm, haven’t read all this post but last time I checked you DO need startAnimation for INdeterminate progressers.
Right – but this code is not meant for an indeterminate progress bar.
Shane, I am listening, but even though I’ve done everything you suggested, the bar isn’t animating. I’m simply trying to find a reason why is damnwell isn’t.
At least when I was not doing things ‘right’ I had an animating progress indicator. I would like one now as well, or I’ll go back to my old ‘incorrect’ script.
Solve this and I’ll shout you a beer if you’re ever in Bendigo.
The indicator is definitely determinate, it has NOT got a barber pole in interface builder.
As for the lot of incrementing, I’ve got 6 possible handlers that a user can select from, 1 thru all of them. Some execute in a few seconds, one (which I posted) takes several minutes. I’ve ‘weighted’ the long one so the progress bar slides along evenly according to the time each takes, not ‘jerking’ from one to the next. I’m fussy about things like that.
In other words, the four minute one uses about 80% of the bar, which is about 11cm long.

Santa
I’ll ask again: what have you set as the bar’s maximum value?
