| ssj71 | is such an else if tree necessary for such a thing? https://github.com/openAVproductions/openAV-Fabla2/blob/master/src/ui/fabla2_ui.cxx#L1184 | 22:33 |
|---|---|---|
| ssj71 | seems like a fairly brutish design | 22:34 |
| ssj71 | I'd think you'd want each widget to have its own associated callback | 22:35 |
| rgareus | ssj71: you could use switch() :) | 22:38 |
| rgareus | ssj71: well, more seriously: every widget should implement that callback | 22:38 |
| ssj71 | but the pointers to the widgets will be determined at runtime | 22:38 |
| rgareus | and the top-level just have a virtual | 22:38 |
| rgareus | assuming C++ | 22:38 |
| rgareus | in C you could use function pointers. set them up when the widget is created. just call the function that's pointed to | 22:39 |
| rgareus | I guess it's early prototying code from Harry. just start somewhere | 22:39 |
| ssj71 | thats what I'd think. Perhaps this is actually his method for widgets to interact? | 22:39 |
| ssj71 | so each widget would have its callback to manipulate its data, but if you want dial 1 to turn dial 2 or something you'd do it here | 22:40 |
| rgareus | still, looks rather odd to me | 22:41 |
| rgareus | one would normally use signals / slot | 22:41 |
| ssj71 | I suppose that could still be accomplished with a per-widget array of function pointers. just run through the list and send your CB data to all the functions | 22:41 |
| rgareus | widget 1 emits a signal. all interested widgets subscribe to it. | 22:42 |
| ssj71 | I'm trying to crack the AVTK code, but afaik fabla2 is the only example | 22:42 |
| rgareus | ssj71: or just shoot harry an email | 22:42 |
| ssj71 | yes thats the next step I guess | 22:42 |
| ssj71 | I keep considering rolling my own C version of AVTK, but thats a lot of punishment for not much gain | 22:48 |
