- has anyone used tkzinc? On the one hand, all the new feature
requests
I've seen for future versions of tk canvas have the caveat that they are already implemented in
tkzinc, (item grouping, transparency, full text rotation, etc.) but it
seems like an unmaintained library at this point.
It does seem unmaintained but to what extent is it unfinished/buggy?
The biggest problem with TkZinc is not what looks like unfinished stuff
or bugs,
it's that although its API looks a lot like the TkCanvas that Pd uses, it's not compatible enough.
I think I must have sent my last message only to András,
my bad
but I looked around at the tkzinc demos and found at least one obvious bug in the latest version. Additionally there was documentation that said rotation would work without using opengl, but on two machine I experienced a crash with the corresponding demo if I compiled without enabling gl support. (Worked fine with opengl enable, though.)
That's why I thought i may have been a configuration problem (not you messing it up but an outdated configure script), because I suppose the output is the same in both cases, it's just handled by a different library - when not direct opengl, mesa trying to emulate it (if i'm understanding mesa right) Anyway, it is a bug
Additionally, one of the demos showing off graphics interaction and transparency was _extremely_ sluggish just moving a few rectangles around on the screen. Add to that another of the demos showing an air traffic control interface where the interval between graphics updates was about 1sec, and I would say I don't think the tkzinc canvas was designed with efficiency in mind.
I don't even know why that stuff was advertised as proof of performace... the famous tiger is a lot more curves and a lot more movement. I mean, i'm sure the air traffic stuff would be able to run 40 times faster (well, maybe i'll even try)
But the grouping stuff and sensitivity levels are very cool. As is the svg tiger.
All I could think of is adding these gems to the "Put" menu array dialog:
Array Properties
Name: array1
Size: 100
[*] Save contents
Draw as: [] Points [] Polygon [] Bezier curve [*] Svg tigers
Put array into: [] New graph [] Last graph [*] Svg tiger
Well, I'd say I wish a GUI toolkit which:
- is truly cross-platform
- provides standard widgets
- provides an equivalent of tk canvas
- can accelerate standard widgets (and, of course, anything else) by opengl
- fast at the backend
- standard widgets preferably skinnable
- can haz svg tiger or other animals... everyone likes a cute penguin, for
instance :o)
Qt is strong contender... Well, qt on the top of tcl? seems to be a dead cow... Qtscript, however, is ecmascript (javascript) based... I woudn't be surprised if this meant some possible synergy with webpd! (which I'd be personally very happy to see)
