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).

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).

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).

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).

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).

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).
