Just tried...the first test I have done was done using this system but I
get
into trouble (better to say complexity) because of the different behavior of
the various values. For example about the different limit a value can have:
color range from 0 to 255, rel1.offset.x from -maxint to +maxint and
text.size
from 0 to +maxint. And also while seaching the object to set the value
to: can be
a program, a state, a part...
You will fall on a function so done
edje_edit_val_int_get(obj,"parts/part/my.part.name/description/default/0.0/rel1.offset.x");
{
switch(type_of_value_to_get)
case rel1.offset.x:
...do the stuff
case color:
...do the stuff
and so on...
}
that is not so different to
edje_edit_rel1_offset_x_get(obj,char* part, char *part)
{
...do the stuff
}
edje_edit_color_get(obj,char* part, char *part)
{
...do the stuff
}
I prefer to add 2 functions (usually get and set) every time edje
change, without have to touch the general code. I'm for making this
api as simple as possible.

This seems to be an unnecessary major complexity, both in the editor and
the
edit_api ... I have to parse the 'long' string first in edje and then
in the editor.
...
Instead I need some help about a way to save the modified edje? I didn't
know
well eet and for now I haven't find a way to rewrite to file :(
Can you give me some direction on this?
Thanks.
