Refresh a plugin listing

[juju0]

Hello,
I'm currently write a plugin and I want to add/remove items by context menu actions.
So I call actions with
item.addContextMenuItems( [ ("foo", "XBMC.RunPlugin(...)") ] )

but once action is done, how to update listing ?
I've tried
xbmc.executebuiltin("XBMC.RunPlugin(%s)"%sys.argv[0])
But it's not work (apparently, Python is launched and crashes when it fills list : nothing changes at screen)

My config : XBMC rev 15340 (Sep 2 2008) on Ubuntu 8.10

Any way you could post your full code? I have an idea but need to see how you've written everything else first....

[juju0]

Sure,
this is an emulator frontend. I'll try to post correct snippets because code is pretty huge and I've coded it with MVC pattern : just controllers (ie core instructions) are interesting here.

Context menu items are added this way (here for delete a platform):
# add menu options
item.addContextMenuItems([
(misc.locale(117), "XBMC.RunPlugin(%s?platform=del:%s)"%(sys.argv[0], pf["platformId"]))
])
As you can see it restarts the plugin with different arguments that are parsed by generic controller constructor :
## Base class for controllers
class BaseController:
## Universal URI pattern
URI_PATTERN = "^\?%s=(.*)$"

## Create common controller utils
# @param action action type (platform, game, rom, run)
def __init__(self, action):
self.db = model.DataBase(DB_FILE)
self.action = action
self.uri = self._parseURI(sys.argv[2])

xbmcplugin.setContent(int(sys.argv[1]), 'files') # <-- May cause a problem ???

print "Action : "+self.action+" ; Arguments : "+str(self.uri)
I don't if it matters but "xbmcplugin.setContent(int(sys.argv[1]), 'files')" is executed all times (even for actions that doesn't display anything).

And platforms controller :
class Main(BaseController):
## Make platform list window
def __init__(self):
BaseController.__init__(self, "platform")

if self.uri is None:
self._fillList() # fills platforms list
elif self.uri[0] == "del": # <-- this condition is True for deleting
self._delete(self.uri[1])
else:
...
self._close() #just close DB properly


Finally following method is called (still for deleting):
## Ask user confirmation and delete given platform
# @param id platform ID
def _delete(self, id):
name = self.db.getPlatformData(id)["name"]
if misc.dlg.yesno(misc.locale(750), misc.locale(30229)%name, misc.locale(30230)):
self.db.delPlatform(id)

Then a final cleanup instruction
sys.modules.clear()
Fails each times ! (I don't know if it's normal or not)

Didn't really show me what I was looking for, I needed how your directory items are actually listed. Anyways, my idea is this: there is a currently undocumented function xbmcplugin.disableCache(handle). You can see the docs for it here: http://xbmc.org/trac/changeset/14439

I haven't actually used it yet, so no idea if this will work, but you can try it out.

Disable the cache on your plugin, then go into a directory that calls a fake function. This should in theory force xbmc to return to the previous directory & repopulate it.

Hope that makes sense?

Either way I'm looking forward the new emulator plugin!

Thanks for answer but disableCache doesn't exists anymore : it's replaced by cacheToDisc parameter on xbmcplugin.endOfDirectory and there's no change ???

And items are added this way :
## fills lists with each found platform.
def _fillList(self):
# lists all platforms
ok = True
fav = misc.getBoolSetting("favonly") # get favourites status
for pf in self.db.getPlatformList():
print pf["name"]
uri = "%s?game=%s:%s"%(sys.argv[0], pf["platformId"], FAVOURITE[fav])
item = xbmcgui.ListItem(pf["name"])
setThumbnail(item, pf["icon"])

# add menu options
item.addContextMenuItems([
(misc.locale(misc.iif(fav, 30016, 30017)), "XBMC.RunPlugin(%s?game=%s:%s)"%(sys.argv[0], pf["platformId"], FAVOURITE[fav])),
(misc.locale(1026), "XBMC.RunPlugin(%s?platform=addpath:%s)"%(sys.argv[0], pf["platformId"])),
(misc.locale(30231), "XBMC.RunPlugin(%s?platform=refresh:%s)"%(sys.argv[0], pf["platformId"])),
(misc.locale(21435), "XBMC.RunPlugin(%s?dialog=editpf:%s)"%(sys.argv[0], pf["platformId"])),
(misc.locale(117), "XBMC.RunPlugin(%s?platform=del:%s)"%(sys.argv[0], pf["platformId"])),
(misc.locale(30026), "XBMC.RunPlugin(%s?dbcleanup)"%(sys.argv[0]))
])
ok = xbmcplugin.addDirectoryItem(int(sys.argv[1]), uri, item, True)
if not ok : break

# append addition buttons
emu = ("%s?dialog=emu"%sys.argv[0], xbmcgui.ListItem(misc.locale(30202), thumbnailImage=ADD_ICON))
newpf = ("%s?dialog=newpf"%sys.argv[0], xbmcgui.ListItem(misc.locale(30212), thumbnailImage=ADD_ICON))
ok = ok and \
xbmcplugin.addDirectoryItem(int(sys.argv[1]), emu[0], newemu[1], False) and \
xbmcplugin.addDirectoryItem(int(sys.argv[1]), newpf[0], newpf[1], False)

xbmcplugin.addSortMethod(handle=int(sys.argv[1]), sortMethod=xbmcplugin.SORT_METHOD_LABEL)
xbmcplugin.endOfDirectory(int(sys.argv[1]), ok, cacheToDisc=False)

Thanks for answer but disableCache doesn't exists anymore : it's replaced by cacheToDisc parameter on xbmcplugin.endOfDirectory and there's no change


Right you are...

Have you tried simply adding rerunning the plugin after _delete, giving arguments to put the user back where he was?

Not sure what else to try if that doesn't work...
Maybe post a feature request on trac for xbmcplugin.refreshDirectoryItems() or something like that...

[juju0]

Still not working : items adding still fails xbmcplugin.addDirectoryItem() returns False when I try re reload list.

I've noticed that "directory handle" is -1 and after lots of searches, I still not understand what exactly is that handle ??? may be it's the problem source ?

[jmarshall]

Try just calling "Refresh" as a builtin perhaps?

I don't have the actual format in front of me - you can find all builtins listed in CUtil::ExecBuiltIn() (xbmc/Util.cpp)

Cheers,
Jonathan

Fantastic ! It works ! Thank you.
The correct call is :

xbmc.executebuiltin("Container.Refresh")

after an action.

[rwparris2]

Glad you got it working

Guess we should start using the appropriate .cpp files instead of the docs.

[jmarshall]

Glad you got it working :)

In an effort to answer the emails and search patterns requesting active plugin currently in use on 5ThirtyOne, I’ve widdled through the plugins page deciding which ones I relied on most. I realized that quite a number of plugins were activated, yet unused. So I thank readers for their inquiries which prompted me to do a little Spring cleaning and sharing.

Is it possible to delete an item from the container directly?
