Helo,

I've got problem with managing menu list.

My code looks like bellow:

Python

class MyMenu(Screen):
skin = """
    <screen position="50,50" size="740,420" title="Subtitle downloader" >
    <widget name="fileList" position="10,10" size="520,150" scrollbarMode="showOnDemand" />
<widget name="subsList" position="10,180" size="520,150" scrollbarMode="showOnDemand" />
</screen>"""


def __init__(self, session, args = 0):
self.fileListEnable = 1
self.subsListEnable = 2
self.selectedList = 0
self.session = session
Screen.__init__(self, session)
list = []
list.append((_("subtitle one"), "one"))  #ADD LATER
list.append((_(""subtitle tto"), "two"))  #ADD LATER


self["subsList"] = MenuList(list)
self["subsList"].selectionEnabled(0)
self["fileList"] = FileList("/")
self["fileList"].selectionEnabled(0)
self.set_listSubs_enabled()


self["myActionMap"] = ActionMap(["ChannelSelectBaseActions","WizardActions", "DirectionActions","MenuActions","NumberActions","ColorActions"],
{
"ok":  self.ok,
    "back":self.cancel,
    "nextMarker": self.set_listSubs_enabled,
    "prevMarker": self.set_listFile_enabled,
    }, -1)


def set_listFile_enabled(self):
self["fileList"].selectionEnabled(1)
self["subsList"].selectionEnabled(0)
self.selectedList = self.fileListEnable


def set_listSubs_enabled(self):
self["fileList"].selectionEnabled(0)
self["subsList"].selectionEnabled(1)
self.selectedList = self.subsListEnable

Alles anzeigen

After execution screen looks like below:

I can switch between lists and on subslist I can make selection:

BUT ON FILE LIST I CAN'T MAKE ANY SELECTION:

I found solution. It seems that in case of two Menu Lists You have to use class Menu list function down or up and sign them directly to key.

My code is now:

Python

class MyMenu(Screen):
	skin = """
	    	<screen position="50,50" size="740,420" title="Subtitle downloader" >
	    	<widget name="fileList" position="10,10" size="520,150" scrollbarMode="showOnDemand" />
		<widget name="subsList" position="10,180" size="520,150" scrollbarMode="showOnDemand" />
		</screen>"""	

	def __init__(self, session, args = 0):
		self.fileListEnable = 1
		self.subsListEnable = 2
		self.selectedList = 0
		self.session = session
		Screen.__init__(self, session)
		list = []
		list.append((_("subtitle one"), "one"))  #ADD LATER
		list.append((_("subtitle two"), "two"))  #ADD LATER

		self["subsList"] = MenuList(list)
		self["subsList"].selectionEnabled(0)
		self["fileList"] = FileList("/")
		self["fileList"].selectionEnabled(0)
		self.set_listSubs_enabled()

		self["myActionMap"] = ActionMap(["ChannelSelectBaseActions","WizardActions", "DirectionActions","MenuActions","NumberActions","ColorActions"],
		{
			#"ok": self.ok,
			#"cancel": self.cancel
		    	"ok":  	self.ok,
		    	"back":	self.cancel,
		     	"nextMarker": self.set_listSubs_enabled,
		    	"prevMarker": self.set_listFile_enabled,
		    	"up": self.goUp, 	#additional function to add multi list selection possibility
		    	"down": self.goDown,   #additional function to add multi list selection possibility
		     	}, -1)

	def set_listFile_enabled(self):
		self["fileList"].selectionEnabled(1)
		self["subsList"].selectionEnabled(0)
		self.selectedList = self["fileList"]

	def set_listSubs_enabled(self):
		self["fileList"].selectionEnabled(0)
		self["subsList"].selectionEnabled(1)
		self.selectedList = self["subsList"]

	def ok(self):
		if self.selectedList == self["fileList"]:
			pass
			if self["fileList"].canDescent():
				self["fileList"].descent()
			else:
				file = self["fileList"].getCurrentDirectory() + self["fileList"].getFilename()
				#self["myPrices"].
		if self.selectedList == self["subsList"]:
			pass # in this moment nothing

	def cancel(self):
		print "\n[MyMenu] cancel\n"
		#TODO Configuration saver
		self.close(None)

	def goUp(self):         	 #additional function to add multi list selection possibility
		self.selectedList.up()

	def goDown(self):     	 #additional function to add multi list selection possibility
		self.selectedList.down()

if you store the list name in the variable you can make the code a bit easier to read:

Code

self.selectedList = "fileList"
...
	def goUp(self):         	 #additional function to add multi list selection possibility
		self[self.selectedList].up()

	def goDown(self):     	 #additional function to add multi list selection possibility
		self[self.selectedList].down()
