widget: fix class private data usage to be _init() safe Before this commit, adding GtkWidgetAction to class private data would require copying the actions to each subclass as they were built or modified. This was convenient in that it is a sort of "copy on write" semantic. However, due to the way that GTypeInstance works with base _init() functions, the "g_class" pointer in GTypeInstance is updated as each _init() function is called. That means you cannot access the subclasses class private data, but only the parent class private data. If instead we use a singly linked list of GtkWidgetAction, each subclass has their own "head" yet all subclasses share the tail of the GtkWidgetAction chain. This creates one bit of complexity though. You need a stable way to know which "bit" is the "enabled" bit of the action so we can track enabled GAction state. That is easily solved by calculating the distance to the end of the chain for a given action so that base classes sort ahead of subclasses. Since the parent class always knows its parent's actions, the position is stable. A new dynamic bitarray helper also helps us avoid allocations in all the current cases (up to 64 actions per widget) and dynamically switches to malloc if that is to ever be exceeded.

If instead we use a singly linked list of GtkWidgetAction, each subclass has their own "head" yet all subclasses share the tail of the GtkWidgetAction chain. This creates one bit of complexity though. You need a stable way to know which "bit" is the "enabled" bit of the action so we can track enabled GAction state. That is easily solved by calculating the distance to the end of the chain for a given action so that base classes sort ahead of subclasses. Since the parent class always knows its parent's actions, the position is stable. A new dynamic bitarray helper also helps us avoid allocations in all the current cases (up to 64 actions per widget) and dynamically switches to malloc if that is to ever be exceeded.

widget: fix class private data usage to be _init() safe Before this commit, adding GtkWidgetAction to class private data would require copying the actions to each subclass as they were built or modified. This was convenient in that it is a sort of "copy on write" semantic. However, due to the way that GTypeInstance works with base _init() functions, the "g_class" pointer in GTypeInstance is updated as each _init() function is called. That means you cannot access the subclasses class private data, but only the parent class private data. If instead we use a singly linked list of GtkWidgetAction, each subclass has their own "head" yet all subclasses share the tail of the GtkWidgetAction chain. This creates one bit of complexity though. You need a stable way to know which "bit" is the "enabled" bit of the action so we can track enabled GAction state.

GtkActionMuxer: store primary accels Reuse the existing infrastructure in GtkActionMuxer for propagation of accelerator information: in particular, what accel label ought to appear on menu items for a particular action and target. This is a good idea because we want accels to travel along with the actions that they're tied to and reusing GtkActionMuxer will allow us to do that without creating another hierarchy of a different class for the sole purpose of filling in accel labels on menu items. Doing it this ways also allows those who copy/paste GtkActionMuxer to insert the accels for themselves. Add a new method on the GtkActionObserver interface to report changes. This patch introduces a new concept: "action and target" notation for actions. This format looks like so: "'target'|app.action" or for non-targeted actions: "|app.action" and it is used over a number of possible alternative formats for some good reasons: - it's very easy to get a nul-terminated action name out of this format when we need it, by using strrchr('|') + 1 - we can also get the target out of it using g_variant_parse() because this function takes a pointer to a 'limit' character that is not parsed past: we use the '|' for this - it's extremely easy to hash on this format (just use a normal string hash) vs. attempting to hash on a string plus a GVariant A close contender was to use detailed action strings here, but these are not used for two reasons: - it's not possible to easily get the action name or target out of the strings without more work than the "action and target" format requires - we still intend to use detailed action strings on API (since they are a lot nicer to look at) but detailed action strings can be given in non-canonical forms (eg: 'foo::bar' and 'foo("bar")' are equivalent) so we'd have to go through a normalisation step anyway. Since we're doing that already, we may as well convert to a more convenient internal format. This new "action and target" format is going to start appearing in a lot more places as action descriptions are introduced. I suspect that nobody is using '|' in their action names, but in case I am proven wrong, we can always switch to using something more exotic as a separator character (such as '\x01' or '\xff' or the like).

widget: fix class private data usage to be _init() safe Before this commit, adding GtkWidgetAction to class private data would require copying the actions to each subclass as they were built or modified. This was convenient in that it is a sort of "copy on write" semantic.

It will lead to changes on action groups associated with parent muxers being broadcast to all children (regardless of if anybody there is interested or not). An optimised version will follow soon.

widget: fix class private data usage to be _init() safe Before this commit, adding GtkWidgetAction to class private data would require copying the actions to each subclass as they were built or modified. This was convenient in that it is a sort of "copy on write" semantic. However, due to the way that GTypeInstance works with base _init() functions, the "g_class" pointer in GTypeInstance is updated as each _init() function is called. That means you cannot access the subclasses class private data, but only the parent class private data. If instead we use a singly linked list of GtkWidgetAction, each subclass has their own "head" yet all subclasses share the tail of the GtkWidgetAction chain. This creates one bit of complexity though. You need a stable way to know which "bit" is the "enabled" bit of the action so we can track enabled GAction state. That is easily solved by calculating the distance to the end of the chain for a given action so that base classes sort ahead of subclasses. Since the parent class always knows its parent's actions, the position is stable. A new dynamic bitarray helper also helps us avoid allocations in all the current cases (up to 64 actions per widget) and dynamically switches to malloc if that is to ever be exceeded.

widget: fix class private data usage to be _init() safe Before this commit, adding GtkWidgetAction to class private data would require copying the actions to each subclass as they were built or modified. This was convenient in that it is a sort of "copy on write" semantic. However, due to the way that GTypeInstance works with base _init() functions, the "g_class" pointer in GTypeInstance is updated as each _init() function is called. That means you cannot access the subclasses class private data, but only the parent class private data. If instead we use a singly linked list of GtkWidgetAction, each subclass has their own "head" yet all subclasses share the tail of the GtkWidgetAction chain. This creates one bit of complexity though. You need a stable way to know which "bit" is the "enabled" bit of the action so we can track enabled GAction state. That is easily solved by calculating the distance to the end of the chain for a given action so that base classes sort ahead of subclasses. Since the parent class always knows its parent's actions, the position is stable. A new dynamic bitarray helper also helps us avoid allocations in all the current cases (up to 64 actions per widget) and dynamically switches to malloc if that is to ever be exceeded.

widget: fix class private data usage to be _init() safe Before this commit, adding GtkWidgetAction to class private data would require copying the actions to each subclass as they were built or modified. This was convenient in that it is a sort of "copy on write" semantic. However, due to the way that GTypeInstance works with base _init() functions, the "g_class" pointer in GTypeInstance is updated as each _init() function is called. That means you cannot access the subclasses class private data, but only the parent class private data. If instead we use a singly linked list of GtkWidgetAction, each subclass has their own "head" yet all subclasses share the tail of the GtkWidgetAction chain. This creates one bit of complexity though. You need a stable way to know which "bit" is the "enabled" bit of the action so we can track enabled GAction state. That is easily solved by calculating the distance to the end of the chain for a given action so that base classes sort ahead of subclasses. Since the parent class always knows its parent's actions, the position is stable. A new dynamic bitarray helper also helps us avoid allocations in all the current cases (up to 64 actions per widget) and dynamically switches to malloc if that is to ever be exceeded.

GtkActionMuxer *
widget: fix class private data usage to be _init() safe Before this commit, adding GtkWidgetAction to class private data would require copying the actions to each subclass as they were built or modified. This was convenient in that it is a sort of "copy on write" semantic. However, due to the way that GTypeInstance works with base _init() functions, the "g_class" pointer in GTypeInstance is updated as each _init() function is called. That means you cannot access the subclasses class private data, but only the parent class private data. If instead we use a singly linked list of GtkWidgetAction, each subclass has their own "head" yet all subclasses share the tail of the GtkWidgetAction chain. This creates one bit of complexity though. You need a stable way to know which "bit" is the "enabled" bit of the action so we can track enabled GAction state. That is easily solved by calculating the distance to the end of the chain for a given action so that base classes sort ahead of subclasses. Since the parent class always knows its parent's actions, the position is stable. A new dynamic bitarray helper also helps us avoid allocations in all the current cases (up to 64 actions per widget) and dynamically switches to malloc if that is to ever be exceeded.

GtkActionMuxer: store primary accels Reuse the existing infrastructure in GtkActionMuxer for propagation of accelerator information: in particular, what accel label ought to appear on menu items for a particular action and target. This is a good idea because we want accels to travel along with the actions that they're tied to and reusing GtkActionMuxer will allow us to do that without creating another hierarchy of a different class for the sole purpose of filling in accel labels on menu items. Doing it this ways also allows those who copy/paste GtkActionMuxer to insert the accels for themselves. Add a new method on the GtkActionObserver interface to report changes. This patch introduces a new concept: "action and target" notation for actions. This format looks like so: "'target'|app.action" or for non-targeted actions: "|app.action" and it is used over a number of possible alternative formats for some good reasons: - it's very easy to get a nul-terminated action name out of this format when we need it, by using strrchr('|') + 1 - we can also get the target out of it using g_variant_parse() because this function takes a pointer to a 'limit' character that is not parsed past: we use the '|' for this - it's extremely easy to hash on this format (just use a normal string hash) vs. attempting to hash on a string plus a GVariant A close contender was to use detailed action strings here, but these are not used for two reasons: - it's not possible to easily get the action name or target out of the strings without more work than the "action and target" format requires - we still intend to use detailed action strings on API (since they are a lot nicer to look at) but detailed action strings can be given in non-canonical forms (eg: 'foo::bar' and 'foo("bar")' are equivalent) so we'd have to go through a normalisation step anyway. Since we're doing that already, we may as well convert to a more convenient internal format. This new "action and target" format is going to start appearing in a lot more places as action descriptions are introduced. I suspect that nobody is using '|' in their action names, but in case I am proven wrong, we can always switch to using something more exotic as a separator character (such as '\x01' or '\xff' or the like).
