Speed up resizing of app designer gui

I have a fairly large gui with daisy chained tab groups panels and many individual ui elements. Meanwhile, the time for resizing of the window has become inappropriately big. (>1min).

Inside the tab groups panels are distributed by a grid layout. The auto resize children option is on.

Are there any rules/suggestions how to avoid/debug long resize events?

Using the profile viewer during a resizing leads to this output:

Unfortunately this does not help me to improve my gui.

Thanks in advance,

For a gui, I always manually define the size a location of all my objects. I find it best to use normalized units. If I have several objects, say 3, that I want to distribute evenly within my figure, I just use ratios in the form of fractions for the height.

figure('units','normalized',...
    'position',[0.3 0.3 0.3 0.3])
h.but1 = uicontrol('sytle','pushbutton',...
    'units','normalized',...
    'position',[0 2/3 0.3 1/3],...
    'string','button1')
h.but2 = uicontrol('sytle','pushbutton',...
    'units','normalized',...
    'position',[0 1/3 0.3 1/3],...
    'string','button2')
h.but3 = uicontrol('sytle','pushbutton',...
    'units','normalized',...
    'position',[0 0 0.3 1/3],...
    'string','button1')

The position and sizing can always be changed later. I find it sometimes useful to reference the previous size, expecially if you are using uitable. (uitable has a property called 'extend' that lists the extension of the table so you don't have any remaining white space).

h.but1.Position = h.but1.Position + [0 0 0.2 -0.1];

Is this what you were refering to? Or is it something else in your gui that is slowing down resizing the whole figure?

The positioning of the uielement is done by a grid layout in my application.

app.GridLayout = uigridlayout(app.ATab);
app.GridLayout.ColumnWidth = {'1x','1x','1x','1x','1x','1x'};
app.GridLayout.RowWidth = {'1x','1x','1x','1x','1x','1x'};

app.editOff= ...
    uieditfield(app.GridLayout, 'numeric',"Value",0);
app.editOff.Layout.Row = ii+kk+1;
app.editOff.Layout.Column = 4;  

I don't want to change the size during the execution through a script. The problem is when whole figure is resize by changing the window size. The complete process takes a while.

But I don't know the main cause, and it is not clear to me how to locate it.

Do you have any data stored/plotted in your gui? The GUI may be slow due to the amount of data held; this also goes for a large number of objects in the GUI. Have you also tried running it on a different machine?

[Philipp Soentgerath]

During the run time serveral axes and one hugh table are created dynamically, but resizing is equally slow before and after this.

I think the sheer number of elements could be the problem. There are serveral hunderds of them, distributed over 8 tabs. So only ~100 are present in the figure. (Don't know if that helps). All other gui interactions still work fine without a bothering delay.

The problems occurs on every machine (3 pc with very similar configuration) and they are professional workstations.
