Clearing cell decorations in editable table cell [message #1507228]

We have an editable table. One of the editable columns is of type AbstractColumn<TriState> and we use execDecorateCell() to set icons representing the three possible states (unchecked, checked, indeterminate).

Furthermore, we have overwritten execPrepareEdit() to return a TriStateField (a custom control offering a checkbox which toggles through three states) so the user can change these values.

Functionally, this works, we can click in the cell, get the tristate field, can modify the value which then gets written back to the tristate value and the cell decoration is updated.

However, the cell decoration is still visible when the tristate field is drawn, which is confusing and ugly.

Is there any way to clear the cell decoration in execPrepareEdit()? We've tried setting the icondId on the cell to null. Sadly, this does not clear the icon, instead it makes the input field disappear (probably because setIconId() triggers a call to execDecorateCell()).

Is there any way to do this?

This reminds me what we have discussed here: https://www.eclipse.org/forums/index.php/t/796088/

I am not sure if there is a solution... This might be a bug/a limitation of the current SWT renderer.

I had forgotten about the fact that you had already mentioned the lack of a way to hide the icon when editing the field in that old discussion.

Thanks for the reminder, I'll open a bug to see if there is a way to have this fixed.

The requirement was implemented with https://git.eclipse.org/r/#/c/55461/ (will be included in mars.1 rc3)

--> The cell-ediotor will now always be installed over the entire cell. If a icon is present it will be hidden. (same behavior as in Swing). Therefore, with this solution there is no need to clear the icon in the execPrepareEdit() method.
