Re: [clutter] clutter-gtk CSW work
Excellent work! What is the long term plan for Clutter-Gtk? Will we see Gtk depending on clutter in the near future?

The work also includes a bunch of test cases to check ref-counting, reparenting and a bunch of other things work correctly. It also includes some demos of intermixing Clutter work with GTK+ (some of these are quite hacky). Performance is ok, but some transient updates (like short button presses) can be lost if the widget tree is large (looking into this).

[clutter] Keyboard events when using GtkClutterEmbed

[clutter] clutter_texture_set_from_rgb_data
Hi All, I'm trying to understand what values I need to enter for the function clutter_texture_set_from_rgb_data, see below: rowstride : Distance in bytes between row starts. bpp : bytes per pixel (Currently only 3 and 4 supported, depending on has_alpha) Thanks
Re: [clutter] clutter_texture_set_from_rgb_data
Thanks for that. I'm assuming my RGB data is 24bit, I'm using standard SVG files. On Tue, Jul 7, 2009 at 2:44 AM, Uday Verma uday.ka...@gmail.com wrote: I think it would depend on what kind of RGB (24-bit, 3 bytes per pixel) data you have, whether it has alpha channel along with the RGB channel (RGBA) (32-bit, 4 bytes per pixel). so if you have just plain 24-bit per pixel RGB data, you need to pass 3 for bytes per pixel, otherwise its going to be 4. The rowstride would be a little more tricky. I thing it will be width * (3 or 4, depending on the kind of data, or bytes per pixel) rounded up to a multiple of 4. so for a 640x480 image, with RGB, the the rowstride would be 640*3 (it is divisible by 4), for an image like 201x100 with RGB data it would 201*3 = 603 rounded up to a multiple of 4 = 604 (divisble by four). I think this is how it works. Somebody, please correct me if I am wrong. A simple bit operation can always give you the correct result: rowstride = ((width * bpp) + 3) (~0x3) Hope this makes sense.

Re: [clutter] Capturing image data from stage save as video file.

[clutter] ClutterMotionEvent and moving clutter actor
I'm trying to allow the user to move my actors around by using the ClutterMotionEvent and clutter_actor_set_position. It works, but if I move the mouse too quickly the actor is 'left behind' so to speak. If I move the mouse back of the actor then slowly move the mouse then I can continue to move the actor without having to re-click the mouse button. Could the issue be that I am calling the clutter_actor_set_position on each callback? I wouldn't have thought this would have that much overhead that it would cause this issue. Any idea's?

I didn't try it, but you probably can have a ClutterGroup as the actor
in GtkClutterViewport. Then you are free to add as many actors to that
group.
Try that, and let us know! :)

[clutter] Combination Events
Can somebody give me an example of capturing the following: - a left click - a left click with the control key held down - a left click with the shift key held down Thanks
[clutter] GtkClutterViewport
It's great to see this in Clutter, but I'm not sure it behaves as expected. I've attached a couple of images to show 'what I would expect'. The two images are of a standard 320 X 240 window and the same window maximized. It appears that it is irrelevant whether the window is maximized or not, the scrollable area is always the same. This makes little sense to me, I would have expected a maximized window to no longer 'need', or be able to be scrolled. using clutter-gtk (trunk) attachment: Maximized.pngattachment: Normal Size.png

Re: [clutter] clutter_actor_move_by and clutterbox2d
Alternatively, could I set the actor as 'manipulatable' - some how prevent
the stage from receiving input and send synthetic drag signals to the
actors? Seems to me that it would be easier and more logical to not set
actors as manipulatable and simply move them around using clutter functions
(I did try this by the way but it seems if I don't set an actor's mode, it's
not visible at all).
Looking forward to hearing back.
Thanks and great work.

a. How do I move my actors around (and still simulate)
You should be able to set the position and rotation of the actors
using clutter_actor_set_position, clutter_actor_set_rotation like
normal. ClutterBox2D doesn't mirror the complete set of
transformations possible using the ClutterActor properties, for now
only position and rotation is honored.
b. How do I prevent users from manually grabbing actors and moving them
around.
This only happens when the ClutterBox2d-container child property
manipulatable is set.

Re: [clutter] clutter_actor_move_by and clutterbox2d
I've made some changes to the example provided with clutter-box2d to
illustrate my issue. You'll notice that you can see the left most hand
'attempt' to move but doesn't (or can't).
**
scene-table.c (I also changed util.c [add_hand function] to name the actors)
**
#include clutter/clutter.h
#include clutter-box2d.h
#include blockbox.h
ClutterActor *move;
gboolean moveactor(void)
{
printf(TIMEOUT\n);
gint x,y;
clutter_actor_get_position (move, x, y);
printf (X: %i Y:%i\n, x, y);
clutter_actor_set_position (move, x + 1, y - 1);
return TRUE;
}
void
scene_table (Scene *scene)
{
ClutterActor *stage;
ClutterActor *group;
ClutterVertex gravity = {0,0};
gint i = 10;
stage = clutter_stage_get_default ();
group = clutter_box2d_new ();
add_cage (group, TRUE);
scene-group = group;
clutter_group_add (CLUTTER_GROUP (stage), group);
clutter_box2d_set_simulating (CLUTTER_BOX2D (group), simulating);
g_object_set (group, gravity, gravity, NULL);

{
gint x, y;
x = clutter_actor_get_width (clutter_stage_get_default ()) / 2;
y = clutter_actor_get_height (clutter_stage_get_default ()) * 0.8;

[clutter] Stage size
Hi, What relevance does the size of the stage have to actors contained in it? I can create a stage with a width of 640 pixels yet can place actors at 800 - why is this?
[clutter] Zoom of sorts
Hi all, I'm wanting the user to be able to zoom in and out of my stage (using the scroll button on the mouse), what would be the best and most efficient way of doing this?
Re: [clutter] Clutter-box2d
Great work. Will the HTML documentation be updated?

[clutter] Templates and Effects
Hi, I've setup a template and have applied it along with effects to an actor. However, in some situations I need to be able to stop it (template/timeline) mid execution on a particular actor. How do I accomplish this?
[clutter] Create array of ClutterActor
Hi,
My application will be using an unknown number of clutter actors at build
time. I'm wanting to create a struct of arrays that I can later realloc when
required.
struct cNode
{
int numNodes;
ClutterActor *clutterArray[1];
cairo_t*cr[1];
};
Is this the correct way to go about this? Is there a better way?
