Listener Question

[BobPhoenix]

I think I know the answer to this but I have to ask. On other Widgets you can set one of its properties like this:

=GetProperty("properties_file_key", "default")

But can you set the "Listener Type" property on a Listener this way?

It doesn't appear to work but I thought I might have something wrong like the case or spelling of the event.

Is anyone else doing this to set a listener type?

I never played around with that idea until just now. I'm sure someone else must be doing that already, but my results showed that it doesn't seem to always reload the listener's type value every time you go back to the menu, so it may be using what was in its cache.

Basically: it worked for me to set the listener's type to be equal to some variable or property value, but once set, it didn't catch a new value unless I used F5 on the menu widget to force a reload of the menu. That should mean that it would load the value & use it properly when you restart SageTV after making the change. I'm going to see about getting more details on this.

The property name is 'ListenerEvent' (seen from browsing the XML STV)

I Get it in my multifunction stop import hook...

But, aren't you talking about getting the widget & changing its value via SetWidgetProperty() as part of the import process, rather than using a dynamic property assignment to set its value on the fly as the STV is in use? I believe he wants to have a setting to choose which command is used for some functionality.

Yes I have used that in the STVImported hook but with other Widgets you can do it while the GUI is running.

That is correct I would like to modify it on the fly and set up a popup for the User to change which event to use. Thanks for testing this I wasn't able to get as far as you did so I know it is possible just have to see what I did wrong. Was trying the Custom1-5 commands.

If Custom1-5 are the only ones you're interested in, you could just listen for all of them and call PassiveListen on the ones that aren't enabled:

Listener: Custom1
    targetval = "Custom1"
        if GetProperty("key", ...)
Listener: Custom2
    targetval = "Custom2"
        if GetProperty("key", ...)
Listener: Custom3
    targetval = "Custom3"
        if GetProperty("key", ...)
Listener: Custom4
    targetval = "Custom4"
        if GetProperty("key", ...)
Listener: Custom5
    targetval = "Custom5"
        if GetProperty("key", ...)
            > targetval
                do your thing
            > else
                PassiveListen()

Not as sexy as the dynamic property, but it should work.

That's how I have it currently in one of my plugins but I just wanted more options. Specificly I was looking at a plugin that would allow the user to define any event and direct it to any menu in SageTV. Coding all of the Event Types is possible but I would definately like another option if possible.

The listener type is definitely cached, so a dynamic value isn't going to work to update the listener automatically. It _might_ work if you have the user restart after making a change, but I'm not entirely sure about that... and users might not like having to restart.

You may want to just stick to the 'standard' way of checking the setting for a limited series of commands, as above.

I was afraid of that. Oh well thanks for checking. Just like to have options.
