Hi,
Scrollbar = a bar that allows you to scroll. ;) Slider = something that
slides. ;) Same thing, really. I suppose if you look at it from the
point that sliders have no increase/decrease buttons on the end of their
bars, then I can see the difference... However, to get slightly off
topic for a moment, sliders aren't that great... For example, if I want
to increase a colour value I'd much rather have a scrollbar then a
slider (because of the ability to 'step' through values)...
What I meant was scrollbars and sliders (AKA trackbars) are different
controls, i.e. different code altogether. Although you could use either
of them for the same purpose, it wouldn't be standard. Sliders come with
tickmarks (which are disabled on Chaoscope to minimize their size) and
selection range. Scrollbars thumb size varies in proportion to the
scroll area size.
You can step through values with sliders as well, just click on the
wedge, either side of the thumb.
Using a scrollbar in an interface for the user to define a value is
total evil.
Well, I suppose so. ;) Again, I think this really works with what we've
been discussing regarding stopping a render. Implementing it there
would work great... I'm curious, though - any ideas how you're going to
set these methods up? For example, are you going to ask the user, via a
pop-up for example, if they want to continue or stop since one of their
criteria has been met, or is it going to be more interface related (via
boolean(s))?
Interface related : a check box next to each properties. If all of them
are unchecked, it's up to the user to stop the rendering.
Imagine if it was a pop-up, you could get a message like :
"Attractor iterations reached 100,000,000. Would you like to stop the
rendering? Please note you set the view iterations to 250,000,000 so
there could be 150,000,000 more iterations to go. Please note you set
the iterations timer to 20 minutes 0 seconds. 19 minutes 50 seconds have
elapsed since you started rendering. You have 10 seconds to answer Yes
or No. Hurry up." :-)
I'll probably work on a very
basic script-maker for rotating animations (imagine a strange attractor
in a micro-wave) and I'll leave the more advanced stuff to other
programmers. I'll have to describe the project file format in detail.
Or rotating like one of those chicken 'heaters' (rotation over/through a
horizontal, as well as a vertical, line)?
Okay, we'll have three radio buttons for the script-maker animation
type :
- Rotisserie (X axis)
- Microwave (Y axis)
- Washing machine (Z axis)
