Event on arrow key selection?

From what I can tell, there is no way to catch selection events when moving a selection with the arrow keys. An example: I subscribe to cell clicks with

grid.on_cell_click(cell_changed)

So if I click a cell, my function "cell_changed" triggers. But if I now use the arrow keys on the keyboard to navigate to the next cell I get no event.

Is there such an event? If not, this is a feature request. :-)

That would be a nice feature

[ipcoder]

Agreed!

you can observe selections:

from ipydatagrid import DataGrid
gr = DataGrid(pd.DataFrame({"a": list("abcd"), "b": [1,2,3,4]}), selection_mode = "cell")

# watch selections
gr.observe(lambda change: print(change), "selections")
gr.selections = [{"r1": 1, "r2": 1, "c1": 1, "c2": 1}]
            
# watch changes
# gr.on_cell_change(lambda change: print(change))
# gr.set_cell_value("a", 0, "b")
gr

Thx a lot, works like a charm!
