How to resize panel in app Designer?

Hi all

In 2019b, I could resize 2 panels by using slider and Gridlayout. Of course, I didn't use auto-reflow because there are many other elements which were arranged in app. You can see in attachment file.

I knew that slider has only 1 pointer. So, I am wordering how to resize 3 panels as following picture ???

Do anyone have idea, please help me.

Thank you so much.

Unfortunately, Matlab still doesn't have a good approach to dealing with this issue. Maybe you can use a toolbar with predefined options. See app attached.

function ImageClicked(app, event)
    
    switch event.Source
        case app.Image0; app.GridLayout.ColumnWidth(1:2) = {'1x','1x'};
        case app.Image1; app.GridLayout.ColumnWidth(1:2) = {'1x',0};
        case app.Image2; app.GridLayout.ColumnWidth(1:2) = {0,'1x'};
    end

end
