DataModel Abstraction: Example sorting and filtering #582

Closed juliostanley closed 7 years ago

juliostanley commented 7 years ago

Hi, the performance of hypergrid is great! However, I am a little lost with the documentation.

What are the steps to enable sorting and filtering, for the version 1.3.0 of hypergrid (using hyper-analytics tree view data source)?

From master (1.3.0), I am trying to use the tree-view add-on demo (I see that in develop, this is removed). On chrome the sorter does not sort the treeview columns (expected sorting at each depth), and the Filter does not seem to work. For IE11 there is a failure on rendering the headers.

I am using the sample add-ons:

I see hyper-analytics 0.12.0 allows adding a DataSource filter and sorter to the pipeline, but I am not familiar enough with the HyperGrid stack to know which steps I am missing, or what would replace the filter/sorter controller, and or plugins, in order to make the filter and sorter work with the Tree View

@juliostanley We can address your concerns later this week

@dwaynekj sounds good, thanks.

@juliostanley Could you send me an email to dwayne@openfin.co. I tried emailing you but I must've wrote it down wrong

@juliostanley So we have a prelimary example of how sorting interface would look at the moment here particularly we are overriding dataModel.getRow and getValue

We are planning in this ticket in the current sprint to simplify the dataModel interface to just 4 or so verbs to be implemented by user.

Then with filtering, sorting, virtual data, etc, the grid simply renders value that you returned from this methods. It won't care where the data is coming from or how it is managed. The Hypergrid layer simplify renderers cells as fast it can once it has its value. For special cells like header and tree column cells you can define the renderer to implement a UX that indicate what state this data is in (i.e. add an up triangle in the header cell of the relevant column).
