Question

I’m trying to write a GUI with the following structure (only relevant parts):


Window -> VBox -> HBox -> Frame: Input

               -> ScrolledWindow -> TreeView -> ListStore: Output 

As soon as the input is received, a list will we computed that is the output. How do I send this list to the ListStore so that it will be displayed? Do I need to drag references of the parent element along in every element? Or is there an easier way?

Answer 1

You can just keep references of your input and your output, then do the following:

• bind a method to your input, that will be called on update or validation,
• in this method, do the treatment needed,
• at the end of this method, update your output, directly using its reference and its internal functions (configure or else).

There maybe a better way to do it (using Var classes?) but that’s how I would do it.
