Scrolling text -- like movie credits

Bernd's stuff is always beautiful and clever.

Did I miss something?

I do not see a solution to the original question, to have a smooth "Star Wars" type of scroll where each line reduces in textSize almost to invisibility as it scrolls toward the top and out to oblivion.

What have the other examples have to do with that? Or is the original query dead, and i just don't know it?

As far as I can tell, the original request was for just scrolling a list without scrollbars. The Star Wars effect was introduced into the discussion two posts later by Richmond.

Richard,

True. I guess I just got caught up with the Star Wars thing. Still working on it...

Guilty as charged.

Richmond.

So glad you did.

But this is a challenge, or at least it is for me, to make LC do whatever we dream up. It seems as though it should be possible. I am having trouble though, since there is no "textHeight" property that can be applied to individual lines, only whole fields.

You could replace the text with the formattedText to make apparent (non-parapraph) lines independently adjustable.

But I think no matter how hard you try to do this by manipulating field contents, it won't likely perform as well as how other systems handle it.

The key is that it becomes a much harder problem attempting that with actual text, instead working with the image of the pre-rendered text.

If LC had a distort operation for images which would let us bring the top two corners together, that would help a lot.

If one had a critical need for this in LC it could be done quite nicely, by wrapping a compiled graphics library with an external or a Builder library.

Richard.

I am sure that solutions out of the "normal" LC world (or my normal world) can do anything at all.

I just like to kludge stuff together.

But what would the formattedText do for me? I am not concerned with line wrapping (or not), only with the appearance and smoothness of a continuously reducing textSize/textHeight scrolling gadget.

Craig

FormattedText will convert soft wraps to hard wraps, simplifying per-line adjustments.

Craig: you're right that textheight only applies to a whole field, but you could experiment with textshift to push the smaller lines down. I haven't tried it and it would probably be fiddly.

[dunbarx]

Jacque.

Good idea. I had thought about setting the margins, but that property is for the field as a whole as well. But reading about the textShift, it seems that it can apply to chunks, and I can exploit that.

Silly question perhaps but has anyone else ever put an acknowledgements page into an app, and did you ask permission before including a persons name?

[richmond62]

I have put a "thanks" page into my Devawriter and did NOT ask anyone's permission.

Come to think of things, as my father is dead, asking his permission would have been a bit difficult.

You are welcome at any time to thank me in any of your work, and I will not object in the slightest.

Thank you Richmond. I appreciate being able to do that. Anyone else have an opinion on this, one way or the other?

I've put acknowledgments into an About dialog but those were requested by the author of the content. I haven't needed to thank anyone independent of that. However, my name was included in the LC acknowledgments some years ago and they didn't ask (there were dozens of us.)

On the other hand, a client saw my name there and thought there was some kind of collusion going on between me and LC and got pretty angry. I had to ask the team to remove my name in case someone else made the same wildly inaccurate assumption.

So I'd say if in doubt, ask. On the other, other hand if they'd asked me I'd have said "sure!", never dreaming it could be misconstrued that way.
