Implement swipe-select for cells

[Adam Peller]

Should be able to click-drag in the grid. Right now, enhanced grid supports this only on the headers. Should this be a feature on the base grid or some sort of mix-in? or just in the enhanced grid?

I'm not quite sure what 'Should be able to click-drag in the grid.' means. Please elaborate. RE your comment 'Swipe select currently works from headers only and not from cells.', cell selection is not yet supported. Swipe select can be used to select those units that are currently supported (columns and rows).

Click+drag in the grid should select cells, much like it does on column/row headers. I figured that what swipe select means. I would personally find it more intuitive if click+drag on row/column headers were used to move the rows/columns rather than select them.

I'm having trouble understanding this ticket too. Sounds like by "click-drag" you are really talking about selecting via swipe, rather than clicking or dragging. Dragging (w.r.t. Grid) refers to reordering.

As for dragging columns to reorder them, that's already supported in standard grid, see ​http://download.dojotoolkit.org/release-1.3.2/dojo-release-1.3.2/dojox/grid/tests/test_grid_column_reorder.html.

As for reordering rows by dragging them, we had a long discussion about that and decided that since dojo.data() has no API related to ordering of rows, that the best we could support would be some callback from Grid notifying that the rows had been moved. Although it's unclear if that feature is useful people.

As for selecting, looking at ​http://archive.dojotoolkit.org/nightly/dojotoolkit/dojox/grid/tests/enhanced/test_enhanced_grid.html selecting rows via swipe is working fine for me. Selecting columns via swipe is also working fine (at least it highlights them). The only missing feature is selecting a region of cells (ie, a certain set of columns in a certain set of rows), which I believe was deferred because it was unclear that anyone needed it.

I meant drag the mouse. I expect that if I "click" over a cell and then "drag" the mouse it would select a range of cells. Plain and simple. That's what I meant by this ticket. We can call that "swipe select" over cells if that means something to you guys. Right now, swipe select only works on row/column headers. I'd expect it to work in the cells also... I think that functionality is even more basic and may belong in the base grid.

I think this should be a mixin - or in EnhancedDataGrid?...what you are talking about is "Spreadsheet-style" selection. The base grid is not intended to be a spreadsheet.

Ditto from me...

The reason that I don't want this as default behavior is that it changes the mouse actions (that I think) users are expecting for both drag of table rows (ex: dropping a mail message into a folder, as seen on yahoo mail, thunderbird, etc), and with reordering of columns. It's still possible to do those things, by selecting the row first via the checkbox but thats different than the standard feel for tables in UI's, and also different than how dragging works in other widgets like Tree. (BTW I can't figure out how to reorder columns)

Anyway, none of that is related to swipe-select for cells pe se, but rather the swipe-select feature in general.

FWIW, CTRL+ drag is a standard shortcut for COPYING objects, not selecting them. CTRL+click is a standard binding for adding non-contiguous objects to a selected set. Also, cell selection is indeed of interest to a variety of IBM product groups and will be implemented as a plugin feature (as will all of our future enhancements).

Moving these grid bugs to future.
