For figures created by uifigure in Matlab R2021a or later, set the WindowStyle to 'alwaysontop'.

How do you do it with a "msgbox", i.e. keep it always on top? It is still a "figure" and not a "uifigure".
When I try to set 'WindowStyle' as 'alwaysontop', I get error:
>> fig_id = msgbox('test');
>> set(fig_id,'WindowStyle','alwaysontop')
Error using matlab.ui.Figure/set
Functionality not supported with figures created with the figure function.

There are a lot of tools for this job in the FEX, e.g. WindowAPI. This tool can use the Windows HWnd handle as input, such that I expect it to work on not-Matlab windows also - as long as you find a method to get the HWnd...

I don't understand your question. What do you mean?

What I suggested only works within MATLAB. I don't know how to extend it to any window, wait for someone else to answer.
Sorry I couldn't help.

Similar to Jan's suggestion, you can always do the window management with ... your window management tools. Jan's recommendation works in Windows. The following works in Linux.
Attached is a simple function that will set the specified window to be on top. This relies on the use of wmctrl, so you need to have that installed. This works for msgbox windows, regular figure windows, and uifigure windows..
hmb = msgbox('test');
hflg = figure(6);
hfui = uifigure(1);
windowontop(hmb)
windowontop(hflg)
windowontop(hfui)
Of course, you can set other window properties the same way.

Thank you, DGM!
Jan's suggesed WindowAPI works nicely in its demo version, but somehow it doesn't work for me (MATLAB 2021a)! I keep getting this error that WindowAPI_HG2 doesn't exist.
function WinAPI_test
FigH = figure('Color', ones(1, 3), 'Renderer', 'Painters');
% Set topmost status:
WindowAPI(FigH, 'topmost');
drawnow;
>> WinAPI_test
Unrecognized function or variable 'WindowAPI_HG2'.
Error in WindowAPI (line 236)
MexFcn(FigH, varargin{:});
Error in WinAPI_test (line 5)
WindowAPI(FigH, 'topmost');

I have no idea how to use those tools, and I'm in no position to troubleshoot since I don't run Windows.

I have no idea, why this is failing, if the demo runs correctly. I've published a new version, which does do no magic tricks anymore to support old Matlab version (HG1, <= R2014b). Now only one C-mex function is compiled. Please try it again with the new version.

Thank you, Jan! It worked like a charm. :-)

Hi, I want to inform whoever incounters this challage using MATLAB's App Designer, there's a great solution written by Igor Varfolomeev, from my experiance it works great in MATLAB 2018b and 2019b:
Cheers, and thank you Igor!
