Re: [nebula-dev] Tiled canvas widget
|
Could CWT be an empty bundle that re-exports underlying bundles:
o.e.n.cwt.animation
o.e.n.cwt.panning
etc
This way the maintenance would be much easier.
Regards,
Wim

Hi Wim, Hallvard,
Code sharing is the idea behind CWT, so it makes sense to move common code there.
Animation is already part of it, but Gallery currently has its own copy since it does not depend on cwt yet. (actually it comes with a newer version, cwt has to be updated).
The only issue on cwt is that we probably need a clear process for API/behavior changes since they may affect several widgets. This is yet to be done.
On async image provisioning, gallery does not have this since it uses the same API as Tree or Table. Image management has to be made by the user.
This is a good idea. I think the Animation is not part of CWT (Common Widget Toolkit) but it was the idea to put it there, AFIAK. Nicholas isn't that correct?

Hi,
I was considering the structure of GeoMap yesterday and concluded it consisted of three main parts:
- canvas tiled with images
- async provision/downloading of images
- view management including coordinates and zooming levels
Only the third of these is really specific for GeoMap. A tiled canvas with panning and zooming is useful for many applications, particularly grid-based games like sokoban. Async provision/downloading of images is useful to improve performance. (I can imaging the gallery widget needs/has something similar).
Does it make sense to factor out generic code? Does the Nebula project consider cross-component refactoring and code sharing?
