[E-devel] SDL engine and windows (cvs problem)
Hey Windows is case insensitive and in the SDL engine, 2 files have the same name (regardless of the case). May I rename evas_engine_sdl.h to evas_engine.h ?

[E-devel] SDL Engine in windows?
Hello, I have a question regarding the resent SDL Engine updates. Would the engine allow evas on windows? I do not use windows but I do have to program apps for it and it would be really cool to use evas + edje and even have some portability. I know there maybe more issues getting evas etc to run on windows just wondering if it was a step closer. Thanks Frederick - Take Surveys. Earn Cash.

First it's working and you will see something with evas_sdl_test. But I have already a few questions. ok- since you are using sdl native everything - you want to look at the xrender (and possibly gl) engines. these basically will be examples of exactly what you want to do in punting stuff off to the engines with surfaces, caches, etc. etc. :) I wanted to directly manipulate SDL_Surface inside RGBA_Image, but this means that for the destruction, I need to call SDL_FreeSurface or I didn't find a way to do that using the evas_common API. To handle this case, see above :) I implemented my own cache mechanism and copy/pasted all functions destroying some RGBA_Image. Well that is working, but that's definitely not clean. So I extract the cache mechanism and make it an evas API (separate patch in evas-data-cache.diff). But this didn't change the problem with evas_common function, like module loaders and others need to be copied. I really don't know how to handle this case correctly. Perhaps adding some callbacks for freeing and creating new image to evas_common_image_init() could be a solution to this duplication of code. Did you prefer a separate cache API, or should I put it back in the SDL engine ? Right now SDL cache is only handling one RGBA_Image with the same key/filename at a time. This means that if one RGBA_Image is dirty but still referenced, the new one will not be able to evict it. I could fix this by storing a list of RGBA_Image per key/filename, but right now the evas_sdl_test seems to be correct. Did I need to take care of this kind of issue or is it ok this way ? In the same idea, what are the purpose of engine_image_border_set, engine_image_border_get and engine_image_format_get ? They seem empty in all engine I am looking in. the xrender engine uses border_set. the format_get really isnt used - so returning NULL is fine here for now. Now if you tried the test program and hide the SDL output, you will notice that the part that didn't change stays black. To solve this, I need to handle SDL_ExposeEvent, but I don't really know where. As I understood most events are handle in ecore. But X11 backend for example, seems to be aware of this kind of issue. Did I need to check for SDL pending event every time evas_engine_sdl_output_flush is running ? Or did it exist a better way to do that ? thats just a matter of the test program doing it - look at the x11 ones - they actually just loop in a tight loop, poll the x event queue for expose events and add them to damage regions to the evas.

During insertion it test if this limit are ok. If the limit are reached, it made some attempt to evict old object from the cache (calling a callback each time). If he can't insert due to the limit, it could fail, but you can force the insertion if you absolutely want (In that case, it will just not enforce the limit. But I think I need to change the test, so that it still make some attempt to remove old object from the cache).

[E-devel] SDL Engine
Hi,
I started a SDL engine for evas and would like some feedback. First
it's
working and you will see something with evas_sdl_test. But I have already a
few questions.
I wanted to directly manipulate SDL_Surface inside RGBA_Image, but this
means
that for the destruction, I need to call SDL_FreeSurface or I didn't find a
way to do that using the evas_common API. To handle this case, I implemented
my own cache mechanism and copy/pasted all functions destroying some
RGBA_Image. Well that is working, but that's definitely not clean. So I
extract the cache mechanism and make it an evas API (separate patch in
evas-data-cache.diff). But this didn't change the problem with evas_common
function, like module loaders and others need to be copied. I really don't
know how to handle this case correctly. Perhaps adding some callbacks for
freeing and creating new image to evas_common_image_init() could be a
solution to this duplication of code. Did you prefer a separate cache API, or
should I put it back in the SDL engine ?
Right now SDL cache is only handling one RGBA_Image with the same
key/filename at a time. This means that if one RGBA_Image is dirty but still
referenced, the new one will not be able to evict it. I could fix this by
storing a list of RGBA_Image per key/filename, but right now the
evas_sdl_test seems to be correct. Did I need to take care of this kind of
issue or is it ok this way ?
In the same idea, what are the purpose of engine_image_border_set,
engine_image_border_get and engine_image_format_get ? They seem empty in all
