A normal cell editing session is initiated by double clicking on the cell.
In the demobrowser Table Cell_Editor demo, double clicking on the checkbox
cell begins editing of the cell, which in the case of the check box cell
editor, provides the ability to then click on the checkbox to toggle its
state. When the cell loses focus, the value of the checkbox editor is saved
back into the data model and the cell retains that value.
Clearly that's not the user experience that people expect if they see a
checkbox. An alternative is to listen for the "cellClick" event on the
table. That event's data is a qx.ui.table.pane.CellEvent which has both a
row and a column property. Your listener for that event could easily swap
the state of the checkbox and replace the data for that cell in your data
model. Since the table is a virtual widget (providing the ability to handle
hundreds of thousands or more rows of data) and the cells aren't really
widgets, we don't have the luxury and niceties of widgets, so there's a bit
more work involved in getting the same user experience. It's not difficult,
though; just a bit different.
