Hello, I'am trying to hide/show a defined column of the Nebula Grid (12*3)
bellow that contains various GridEditor.
The problem is that even if the column visibility is set to false, the
column is still displayed on the screen.
May I miss something or is it a bug?
Thanks in advance
Rémi

Hi Remi,
Column visibility is an unfinished feature at the moment. You can
workaround this by doing the following:
First, GridColumn.setVisible() isn't redrawing the grid. This can
easily be fixed by simply calling Grid.redraw(). Second, the GridEditor
doesn't have any concept of hidden columns. In order to handle this,
you'll need to set your editor controls visible/invisible when you make
the column visible/invisible. You will also likely have to call
GridEditor.layout() on all your editors when you make a column
visible/invisible.
When column visibility is finished, the appropriate events will be fired
and the GridEditor will know how to respond.
