[patch][ccla]New Grid Prototype

[evan]

Use this ticket to track iterative experiments on new Grid prototypes. We shall discuss and pick up most appropriate solutions among following in-progress experiments(or others):

1. ​Mobile Table prototype
   
2. ​Virtual List
   
3. ​DataGrid Plugin Proposal
   
4. ​Evan's in progress work

Will keep discussion and record any new decisions to the ​Grid 2.0 doc

[Seldarly]

It wold be great to have an ability to group rows dynamicly by any column and have any depth.

In progress work from Evan

notes from Evan:

A in-progress prototype(works except for IE) with most ideas experimented in ​DataGrid Plugin Proposal:

1. UI rendering optimization by minimizing rendering times
2. New virtual scrolling model with "padding position" way - gridx.core._Scroller/gridx.core.ui._PageManager
3. Centralized Event dispatching model - gridx.core._EventManager
4. UI logic division(Column, Row, Page, View) - experiment see if we can make layout(either simple or complex) transparent to other components?
5. DataStore? Wrapper - gridx.core._StoreModel/_Cache (this shall be ported to dojo.store() API)
6. Plugin support - gridx.core._PluginManager

TODO:

1. Fix IE rendering issue;
2. Fix sorting marker alignment issue
3. Optimize performance for single view

Once the patch is applied, please try the following test cases(1000 rows for virtual scrolling)

• dojox/grid/tests/gridx/demo/test_grid.html
• dojox/grid/tests/gridx/demo/test_grid_events.html

A new experiment on virtual scrolling - from Nate(IBM, CCLA) - 1. Scrollbar is separated from the main scroll div; 2. Viewport is filled up, rows are kept being removed/appended when scrolled out/into viewport

Adding a '1.7-mobile' just for ​for 1.7 query

[evan]

New grid v.0.1 - experimenting new virtual scrolling & grid model

[evan]

v 0.2 patch from folks working on new grid(Nate, Oliver, Elvis - IBM, CCLA)

[evan]

"new grid_v.0.2.patch" experimented the idea of module - that is doing decomposition as possible so that we may finally have a set of modules (either in core or plugins), and in this way it's possible to provide several Grid profiles e.g. one profile for MiniGrid?(as a base for MobileGrid??), and another one for AdvancedGrid? etc.

1. ​MiniGrid Sample - with only minimal modules loaded, the list of ​minimal modules
   

2. ​AdvancedGrid sample with more features

Is there any design doc for reference about the vitual scroll mechanism? Thanks!

Replying to gbroad:

Yes, here it is ​virtual scrolling doc

[David Schwartz]

This code will be experimental in 1.7. Just to be clear, though, our intent is to deliver a stable solution in v.1.8, not a prototype, that can/should be used instead of the other grid widgets.
