Re: [clutter] Text Font issue with Clutter 1.0.10
Hi i downloaded clutter 1.2.10 and compiled it with following args. ./configure --with-flavour=eglx --with-gles=2.0 finding the same issue there. Does any one have an idea.

What i experienced is, the very first time i created a cairo texture using cairo apis in between clutter_cairo_texture_create and cairo_destroy, i got a perfect texture. Now if i want to redraw something else on the same texture. i am not able to clean the texture or the cairo context. That is i can see both the drawings, the previous one and the new one overlapping. Is there a way to clear the previous texture or how can i reuse the same cairo-texture rather than destroying the old one and creating a new one again. I tried using cairo_set_source_rgba to clear cairo context, it works for full alpha (1.0), but if alpha is 0.0, the problem arises. By alpha = 0.0 i mean to say, the clutter texture is transparent (i think by default clutter-cairo-texture is transparent) of some width and height. but the cairo drawings are with full opacity.

[clutter] Regarding ClutterFixed
hi I was trying to use tidy adjustment which has ClutterFixed as members. So if try to modify the adjustment value 32767, it overflows. When i checked ClutterFixed implementation its a 16.16. So is there a design issue for making ClutterFixed as a gint32 (16.16)? Can 't it be made gint64(32.32)? Will it give a performance hit? Thanks and Regards Varun

[clutter] Clutter Script Asserts
hi
When i try to un-merge a merge_id returned from
clutter_script_load_from_file
i get following asserts

`CLUTTER_IS_ACTOR (self)' failed
(./a.out:22293): Clutter-CRITICAL **: clutter_actor_destroy: assertion
`CLUTTER_IS_ACTOR (self)' failed
I am just trying to unmerge an id as soon as i get it.
attached test case produces the result
file : test.c and a json file temp.json

test code is working fine as expected, i think i have done some mistake in the application will revert back if i found the problem On Thu, Apr 10, 2008 at 2:53 PM, Matthew Allum [EMAIL PROTECTED] wrote: Hi; Could you write a simple test case showing this and attach to bugzilla.

[clutter] CLutter Script question
hi i have a doubt regarding retrieving objects from ClutterScript The docs for clutter_script_get_object says This function does not increment the reference count of the returned object. Does that mean the object is in floating state and we have to do g_object_ref and g_object_sink to own the ownership or ClutterScript owns a reference to the object and when we do g_object_unref(script), the objects will be unreferenced automatically if we haven't done a g_object_ref on object retrieved. bye

Re: [clutter] Can i use opengl apis in clutter program
CLutter uses OpenGL commands or it uses mesa library for implementing existing clutter actors bye On Jan 31, 2008 3:27 PM, Tomas Frydrych [EMAIL PROTECTED] wrote: varun shrivastava wrote: thanks but where i can find some tutorial about that? There isn't one; if you want to use OpenGL to design a custom actor, then the best thing to do is to have a look at how the existing clutter actors are implemented. If you want to use OpenGL directly outside of a custom actor, then you will need to know enough about OpenGL not to need a tutorial.
