I was just thinking the same as airtonix :)
I use tint2 with openbox and I spent some time yesterday to "fix" the
appearance of
my panel and a openbox theme that I like: my solution was to "flatten" all
gradient
in openbox, but I'd rather applied them to tint2...
Openbox themes have the color/colorTo options for their single elements, and it
would
be perfect if this functionality can be introduced in tint2 for its singles
components (clock, tray, taskbar, tasks, etc).

imlib2 supports linear gradients.
Radial gradients would be nice too.

We are using cairo for drawing backgrounds. The API is the following:
http://cairographics.org/manual-1.0.2/cairo-Patterns.html
Example code:
http://cairographics.org/samples/gradient/
To configure a linear background, a possible option would be to specify:
* the orientation of the gradient, in degrees
* a list of colors and the corresponding distances
* the distances could be given in pixels
* the distances could also be given in percentages. If the gradient is horizontal, we convert them to pixels by muliplying by the object's width; if they are vertical, we muliply by the object's height; if they are at an angle we could use width * sin(angle) + height * cos(angle)
I am not sure about radial gradients.
The relevant parts of tint2 which would be modified are:
* util/area.h (probably add a new member to Background)
* util/area.c (modify draw_background(Area *a, cairo_t *c))
* config.c (read background config options)
This is a lot of work and I don't have time for it but I'm willing to accept
patches (for the release after 0.12). The condition is that performance (CPU &
memory) must not be affected for configs that do not use gradients.

Than you very much for the information and algorithm, in fact that's what i
need.
i'm working on it.
Thank you.

Hi,
I prepared a patch for gradient background and border.
Because of I'm not an experienced developer, most probably it has buggy code.
Please test it before use it.
I could not find any appropirate solution for radial gradient. So I just
implemented linear gradient for now.
New config parameters:
background_color_2 = < same style with the first color >
background_gradient_type = < disabled, linear >
background_gradient_settings = < smoothness( 0 to 5), balance(-200 to 200)
orientationAngle(0 to 360) >
border_color_2 = < same style with the first color >
border_gradient_type = < disabled, linear >
border_gradient_settings = < smoothness( 0 to 5), balance(-200 to 200)
orientationAngle(0 to 360) >
sample:
background_color_2 = #000000 100
background_gradient_type = linear
background_gradient_settings = 5 0 0
Thank you.

Thanks! I will take a look in the weekend.
