I am trying to create a table (UITable_2 with C,D) based on the selected cell of another table (UITable with A,B) . Also, I am trying to set the data of UITable_2 to be editable.

However, while editing a field of UITable_2, if i change the cell selection of UITable, the edit affects the new selection in the UITable rather than previously selected one. Not sure if I put it well.

Here, while the cell with value 1 is selected, if I edit the value in UITable_2 and select value 2 in UITable during the edit, instead of saving the value 3 for the property associated with initial callback (app.a) before moving on, the code jumps to the new callback with 2 and assigns it to the property (app.b) associated with the new cell selected.

How can I ensure that a new cellselection callback completes the previous callback running before executing further??

Following is my complete code :

classdef basic_plot < matlab.apps.AppBase
    % Properties that correspond to app components
    properties (Access = public)
        UIFigure   matlab.ui.Figure
        UITable    matlab.ui.control.Table
        UITable_2  matlab.ui.control.Table
    end
    
    properties (Access = private)
        selectedCell % Description
        a = {0 0};
        b = {0 0};
    end
    
    % Callbacks that handle component events
    methods (Access = private)
        % Code that executes after component creation
        function startupFcn(app)
            app.UITable.Data =[1 2]; 
            app.UITable_2.Data = [0 0];
            app.selectedCell = 1;
            
        end
        % Cell selection callback: UITable
        function UITableCellSelection(app, event)
            indices = event.Indices;
            switch indices(2)
                case 1
                    app.UITable_2.Data =app.a;
                case 2
                    app.UITable_2.Data =app.b;
            end
            app.selectedCell=indices(2); 
        end
        % Cell edit callback: UITable_2
        function UITable_2CellEdit(app, event)
             indices = event.Indices;
             newData = event.NewData;
             switch app.selectedCell
                 case 1
                       switch indices(2)
                        case 1
                            app.a={newData app.a{2}};
                        case 2
                            app.a={app.a{1} newData};
                       end 
                 case 2
                     switch indices(2)
                        case 1
                            app.b={newData app.b{2}};
                        case 2
                            app.b={app.b{1} newData};
                     end 
             end    
           end
    end

For the beginner that I am, what solved it for me was having a drawnow as first line in the cellselection callback that emptied the queue.

This would however refresh all the figures (that is what I read from the doc) and finish the pending processes. If I have many figures and such editable texboxes, is there a way to either 1) specify which task in the queue to finish before moving on for the cellselection callback or 2) have this as a property of the table whose cell is being edited?
