Removing uitable cell selection highlight

32 views (last 30 days)
I have a uitable that includes a checkboxes in column 1 and string-valued entries in column 2. Some of the entries may be "ghosted", which is faked by prepending HTML tags to change their font color to gray. A corresponding bitvector keeps track of the ghosted rows. Clicking in either column on a ghosted row is ignored, with an immediate return from the CellSelectionCallback routine.
This works OK except for one annoyance: When a ghosted string (column 2 of a ghosted row) is clicked, the blue cell selection highlight remains on after the return from the callback. A subsequent click in column 1 of the same row, will remove it, but that's not a good solution. Can anyone suggest a way to programmatically remove it ("deselect" the clicked cell)?
BTW, I just purchased Yair Altman's excellent book Undocumented Secrets of MATLAB-Java Programming, but this doesn't seem to be a covered topic.

This is covered (briefly) at the bottom of page 169 of my book...

This works for me. It's inside the uitable's CellSelectionCallback:
if any(ghostRows == clickedRow)
myTable = src.Data;
temp = myTable;
temp(end) = {'DUMMY'};
src.Data = temp;
src.Data = myTable;
If I click on a ghosted row in the string-valued column, the focus highlight (dotted box around entry) still appears, but I find that much less objectionable than turning the entire cell background blue as happened before.

You could try setting the uitable to 'enable' 'off', drawnow(), then 'enable' 'on' and drawnow()

This accomplishes what I want, which is unlinking the keyboard from the cell. Now the up and down arrows don't navigate cells, which for my particular program was causing other problems. Note, you still have a visual indication of the cell being selected (gray box instead of blue), which in my case is OK. Ideally TMW would just provide a method to implement the actual desired feature! :/

function [] = DeselectCellinUItable()
uif = uifigure();
uif.Units = 'normalized';
uif.Position = [0.10, 0.50, 0.80, 0.40];
uit = uitable(uif);
uit.Units = 'normalized';
uit.Position = [0.10, 0.50, 0.80, 0.40];
uit.Data = cell2table(num2cell(rand(10,7)));
uit.RowName = 'numbered';
uit.ColumnEditable = true;
uit.SelectionType = 'cell';
uit.Multiselect = 'off';
uit.SelectionChangedFcn = @(src,event) DeselectUItable;
function DeselectUItable
uit.Selection = [];
