Hi,
We have a ClutterContent subclass that optionally uses a rounded rectangle
clipping path. The code was developed and tested under Clutter 1.14.2,
displaying the clipped content properly. Under Clutter 1.16.0 (with cogl
1.16) the content is not drawn or is completely clipped out. If the
cogl_path_round_rectangle() call is changed to a cogl_path_rectangle() the
code works.
Original code that worked under Clutter 1.14.2
static void xxx_fill_paint_content (ClutterContent *content,
ClutterActor *actor,
ClutterPaintNode *root)
{
...
if (needClip)
{
gfloat width, height;
ClutterActorBox allocation = { 0, };
clipNode = clutter_clip_node_new();
clutter_paint_node_set_name(clipNode, "Clip");
clutter_actor_get_allocation_box (actor, &allocation);
clutter_actor_box_get_size (&allocation, &width, &height);
CoglPath* path = NULL;
cogl_path_new();
cogl_path_round_rectangle (0, 0,
width,
height,
radius,
arcStep);
path = cogl_get_path();
clutter_paint_node_add_path(clipNode, path);
clutter_paint_node_add_child (root, clipNode);
clutter_paint_node_unref(clipNode);
}
ClutterPaintNode* contentNode = clutter_color_node_new (NULL);
// draw content...
// if clipped, hang content node on clipping node
clutter_paint_node_add_child (hasRoundedCorners ? clipNode : root,
contentNode);
clutter_paint_node_unref (contentNode);
}
Any solution on this? We wanted to upgrade because of the fix for
clutter-offscreen-effect: Allocate the cogl texture directly
https://git.gnome.org/browse/clutter/commit/?id=b416224d
In the meantime we'll try upgrading just to 1.15.2 which is when the above
fix was released.
Reza.
