Implemented Interfaces
ShellGenericContainer implements ClutterContainer, ClutterScriptable, ClutterAnimatable and AtkImplementorIface.
Description
ShellGenericContainer is mainly a workaround for the current lack of GObject subclassing + vfunc overrides in gjs. We implement the container interface, but proxy the virtual functions into signals, which gjs can catch.
ShellGenericContainer is an StWidget, and automatically takes its borders and padding into account during size request and allocation.
Functions
shell_generic_container_get_n_skip_paint ()
guint
shell_generic_container_get_n_skip_paint
(ShellGenericContainer *self
);
shell_generic_container_get_skip_paint ()
gboolean shell_generic_container_get_skip_paint (ShellGenericContainer *self
,ClutterActor *child
);
Gets whether or not actor
is skipped when painting.
shell_generic_container_set_skip_paint ()
void shell_generic_container_set_skip_paint (ShellGenericContainer *self
,ClutterActor *child
,gboolean skip
);
Set whether or not we should skip painting actor
. Workaround for
lack of gjs ability to override _paint vfunc.
Types and Values
SHELL_TYPE_GENERIC_CONTAINER
#define SHELL_TYPE_GENERIC_CONTAINER (shell_generic_container_get_type ())
Signal Details
The “allocate”
signal
void user_function (ShellGenericContainer *self, ClutterActorBox *box, ClutterAllocationFlags flags, gpointer user_data)
Emitted when self
is allocated, after chaining up to the parent
allocate method.
Note that box
is self
's content box (qv
st_theme_node_get_content_box()
), NOT its allocation.
Parameters
self |
||
box |
|
|
flags |
the allocation flags. |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
The “get-preferred-height”
signal
void user_function (ShellGenericContainer *self, gfloat for_width, ShellGenericContainerAllocation *alloc, gpointer user_data)
Emitted when clutter_actor_get_preferred_height()
is called
on self
. You should fill in the fields of alloc
with the
your minimum and natural heights. ShellGenericContainer
will deal with taking its borders and padding into account
for you.
alloc
's fields are initialized to 0, so unless you have a fixed
height specified (via “height” or CSS), you must
connect to this signal and fill in the values.
Parameters
self |
||
for_width |
as in |
|
alloc |
a ShellGenericContainerAllocation to be filled in |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
The “get-preferred-width”
signal
void user_function (ShellGenericContainer *self, gfloat for_height, ShellGenericContainerAllocation *alloc, gpointer user_data)

on self
. You should fill in the fields of alloc
with the
your minimum and natural widths. ShellGenericContainer
will deal with taking its borders and padding into account
for you.
