Table cells to be edited only on double click - matlab

Question

The table cell is edit with a simple click, I want it to be edit only on double click. Simple click will select the cell.
I'm use this property of uitable:
set(hTable, 'Data',data,...
'ColumnEditable', edit,...

Answer 1

First you need to set the cell editabiliy to false by default:
set(hTable,'ColumnEditable', [false false ...]); %accordingly your number of columns
and introduce a CellSelectionCallback:
set(hTable,'CellSelectionCallback',#cellSelect);
which calls the following function within the same script
function cellSelect(src,evt)
getstate = get(src,'ColumnEditable'); %gets status of editability
index = evt.Indices; %index of clicked cell
state = [false false ...]; %set all cells to default: not editable
state(index) = ~getstate(index); %except the clicked one, was it
%already false before set it true
set(src,'ColumnEditable', state) %pass property to table
end
and also a CellEditCallback:
set(hTable,'CellEditCallback',#cellEdit);
calling
function cellEdit(src,~)
state = [false false ...];
set(src,'ColumnEditable', state)
end
minimal example
function minimalTable
h = figure('Position',[600 400 402 100],'numbertitle','off','MenuBar','none');
defaultData = {'insert number...' , 'insert number...'};
uitable(h,'Units','normalized','Position',[0 0 1 1],...
'Data', defaultData,...
'ColumnName', [],'RowName',[],...
'ColumnWidth', {200 200},...
'ColumnEditable', [false false],...
'ColumnFormat', {'numeric' , 'numeric'},...
'CellSelectionCallback',#cellSelect);
end
function cellSelect(src,evt)
getstate = get(src,'ColumnEditable');
index = evt.Indices;
state = [false false];
state(index) = ~getstate(index);
set(src,'ColumnEditable', state)
end
function cellEdit(src,~)
state = [false false];
set(src,'ColumnEditable', state)
end
As you figured out this is not always working. Because you have the same issues like I had before with popup menus. It's exactly the same problem: ColumnEditable is just a row vector and not a matrix. I had to deal with the ColumnFormat property, which is also just a row vector. If the double click feature is really important to you, you can consult the following two answers:
Is it possible to prevent an uitable popup menu from popping up? Or: How to get a callback by clicking a cell, returning the row & column index?
How to deselect cells in uitable / how to disable cell selection highlighting?
The threads basically suggest to create a unique uitable for every single row, so that every single row has a unique ColumnEditable property. That's the only solution so far.
I'm afraid there is no simple solution. I can't offer you further help, except the complicated workarounds of the other answers. Or just use the simple one above and live with the little drawbacks.

Answer 2

Although this thread is old but in my opinion still valuable to some users.
I have tested the following with R2010b 32bit.
I have achieved editing only on double click simply by setting
set(hTable,'CellSelectionCallback',#tableCellSelectCB,'ColumnEditable',true)
and defining its function the following
function tableCellSelectCB(~,~)
try
h.jtable.getCellEditor().stopCellEditing();
catch
end
end
where h.jtable refers to the underlying java object of your uitable.
This way, I can select even single and multiple cells, without going into edit mode. On a double click on a single cells lets me edit its contents.
Extension to have individual editable rows
I wanted to have checkboxes in the top row and non-editable (not directly at least) data in the rest of the table. You can easily modify the above:
function tableCellSelectCB(~,evd)
if evd.Indices(1) > 1
try
h.jtable.getCellEditor().stopCellEditing();
catch
end
end
end
