Hello everyone! So i am kind of new to MATLAB. I created a UI with tabs, however when i maximise the UI figure, the tabs do not resize along with it. How can i manage this? Thank you in advance.

clear all
clc
%Creating Tabs
fig = uifigure("Name","BISC");
set(fig, 'Units', 'normalized', 'Position',  [0.1, 0.1, 0.8, 0.8]);
tg = uitabgroup(fig,'Units','normalized',"Position",[0,0,1,1]);
t1 = uitab(tg,"Title","Data");
tg1 = uitabgroup(t1,'Units','normalized',"Position",[0,0,1,1]); 
t3 = uitab(tg1, 'Title', 'Tab 3');
t4 = uitab(tg1, 'Title', 'Tab 4');
t2 = uitab(tg,"Title","Plots");
tg2 = uitabgroup(t2,'Units','normalized',"Position",[0,0,1,1]);
t5 = uitab(tg2, 'Title', 'Tab 5');
t6 = uitab(tg2, 'Title', 'Tab 6');
t1.Scrollable = "on";
t2.Scrollable = "on";

It seems like having AutoResizeChildren set to 'on' (which is the default) conflicts with positioning children whose Units are 'normalized'. To work around that and have the normalized positions respected, set AutoResizeChildren to 'off' for the uifigure and for the uitabs that contain uitabgroups.

%Creating Tabs
fig = uifigure("Name","BISC",'Units','normalized','Position',[0.1, 0.1, 0.8, 0.8],'AutoResizeChildren','off');
tg = uitabgroup(fig,'Units','normalized',"Position",[0,0,1,1]);
t1 = uitab(tg,"Title","Data",'AutoResizeChildren','off');
tg1 = uitabgroup(t1,'Units','normalized',"Position",[0,0,1,1]);
t3 = uitab(tg1, 'Title', 'Tab 3');
t4 = uitab(tg1, 'Title', 'Tab 4');
t2 = uitab(tg,"Title","Plots",'AutoResizeChildren','off');
tg2 = uitabgroup(t2,'Units','normalized',"Position",[0,0,1,1]);
t5 = uitab(tg2, 'Title', 'Tab 5');
t6 = uitab(tg2, 'Title', 'Tab 6');

Thank you for your answer and apologies for my late reply. I tried your suggestion but nothing changes, my tab sizes still don't resize with maximisation of the figure window.

You're welcome!

What version of MATLAB are you using? I tested it on R2022a, and it seems to work.

[ALEXANDROS]

R2023b. What if i create a function? I haven't tried it yet, as i am busy with other university responisbilities and exams, but it is a thought i had.

I have just tested the solution in R2023b and confirmed that it works.
