gkusnick / Sage API question?

[shadeblue.com]

Hello,

I am working on a plugin using Gkusnick'a wrapper API, but this is probably more of a SageAPI question.

I can use the following code to set a global context variable, which works great...

// create API and Sage Configuration
gkusnick.sagetv.api.API sageAPI = new API();
gkusnick.sagetv.api.Global sageGlobal = new gkusnick.sagetv.api.Global(sageAPI);
            
sageGlobal.AddGlobalContext("test","test var value");

But how do I set a context variable for a specific UI context, one that I don't want to be global?

Thank You,

You're getting confused by two different meanings of "global". AddGlobalContext does not affect all UI contexts; it affects only the one in which it's called. "Global" in this case means visible to all widget code in that UI context (as compared to Attribute variables, whose scope is limited to a subset of widgets). There is no such thing as a global variable visible to all code in all UI contexts (unless you count property file entries).

When you instantiate the API object with no UI context argument, you're not getting a "global" API that affects all contexts. You're getting one with no UI context at all, i.e. one that can be reliably used only for core functions and not for UI functions. To affect a specific UI context, pass that context in when you instantiate the API object.

Also, you don't need to instantiate the Global class. The API object already contains a public instance of that class (i.e. sageAPI.global).

Greg,

Thanks for the info! That helps explain things much better.

On the Attribute variables you mentioned where their scope is limited to a subset of widgets in a chain, is there a way from the API to set the value of one of these variables.

For example, if I find a widget in a UI context that defines a variable, can I update this variables runtime value from the API? I don't want to update the permanent value to the widget causing a change to the STV file, just the value of the variable at runtime where I may execute a chain a widgets after this variable value widget.


Thanks, shadeBlue

No, there is no way to read out or change runtime variable values through the API, except for AddGlobalContext and AddStaticContext.
