Create a new tab (window) in app designer while still having the old tab open

Hi,

I have an app designer app that plots data sets and can overlay lines and distributions on the plot. It can do this for many different data sets.

I'm wondering if there is a way to open a new tab (like in a browser) so that I can start plotting other data sets from scratch while still having the other plot open in an old tab?

Clearing the plot is not what I want to do. I need the older plot to still be there.

I have researched the idea and found a solution to have the 'new tab' button open another instance of the app designer app (App Designer: How to open a second GUI or a new window with panels, lamps, edit fields, etc. by a ButtonPush callback ? - (mathworks.com)) however I would rather have everything in the same window and the 'new tab' button open a new tab using the tab group container built into app designer.

I hope this question makes sense, and I'd really appreciate any advice or help on the issue.

You can use the uitab function to add a uitab into your tab panel:

https://www.mathworks.com/help/matlab/ref/uitab.html

You'll then have to manually create the elements you want in that tab. Instead of dragging and dropping the ui elements from the library, you can use the command-line functions. E.G.

t = uitab(app.TabGroup);
uia = uiaxes(t);
plot(uia,x,y)

Thank you for your response. I have a button setup to open a new tab now

uitab(app.DistributionFitterTabGroup,'Title',['Tab ' num2str(app.tabNum)]);
            app.tabNum = app.tabNum + 1;
            
            if app.tabNum > 2
                app.CloseTabButton.Enable = "on";
            else
                app.CloseTabButton.Enable = "off";
            end

As you mentioned above, I will have to manually create all the elements in the new tab but is there a way to copy all the elements in tab 1 to tab two when tab 2 is created?

Hey,

you can create a button that will add a new tab.

t = uitab(parent,Name,Value);

Where parent is the handle to the existing uitabgroup component you want to add the tab to.

If you would like to copy all the callbacks and other objects, try with function copyobj. I have never tested it, but it probably should work. Otherwise, you can set up the whole graphic object and wrap it up in a function.
