Since the “CellEditEvent” data doesn't provide direct information about the input method used to trigger the callback, we can use a workaround by introducing a flag to track the last input method. This flag will be set within a “KeyPressFcn” that listens for the Enter key. When the “CellEditCallback” is invoked, it will check this flag to determine the next action allowing for different behaviours based on the input method.
Here's how you can implement this solution:
Firstly, add a private property to your app class to store the last input method:
properties (Access = private)
LastInputMethod = 'mouse'; % Default to mouse
end
Next, define a “KeyPressFcn” for the table to update this property when the Enter key is pressed
function UITableKeyPress(app, event)
if strcmp(event.Key, 'return')
app.LastInputMethod = 'keyboard';
else
app.LastInputMethod = 'mouse';
end
end
In the “CellEditCallback”, you can then check the LastInputMethod property:
function UITableCellEdit(app, event)
indices = event.Indices;
if strcmp(app.LastInputMethod, 'keyboard')
% Move focus to the cell below if the Enter key was used
nextRow = indices(1) + 1;
if nextRow <= size(app.UITable.Data, 1)
app.UITable.Selection = [nextRow, indices(2)]; % Move focus to the cell below
end
end
% Reset the input method to mouse after processing
app.LastInputMethod = 'mouse';
end
Make sure to assign both the “KeyPressFcn” and the “CellEditCallback” to your table. You can do this in the “startupFcn” of the app
function startupFcn(app)
app.UITable.KeyPressFcn = @app.UITableKeyPress;
app.UITable.CellEditCallback = @app.UITableCellEdit;
end
