app.UIfigure.Visible does not keep the app window on top of all other windows

Hi all

using the following line does not really keep the app window in appdesigner on top of all other windows , I have two pushbuttons and for each, the window should remain on top:

app.UIFigure.Visible = 'on';

Try using drawnow with the figure command in your button callbacks (see this post)

drawnow;
figure(app.UIFigure)

Dear Cris, Maybe I was mistaken, I am talking about the main app window, I don't have a figure window. does this command work on the app window ?

[Cris LaPierre]

Yes, this is for the main app window, which is a blank figure that you can build on. You'll have to call it whatever you named your figure window (if you changed the name). What I shared uses the default name.

Thank you , I did this, still did not succeed :

            app.selectedPath = uigetdir();
            drawnow;
            figure(app.UIFigure)
            app.UIFigure.Visible = 'on'; 
            currentFolder=app.selectedPath;
            cd(currentFolder)
            assignin('base','currentFolder',currentFolder);

I'm having a hard time picturing what your layout is. How many app windows do you have open? Where are the pushbuttons if not on the main app window? How does pushing a button cause the main window to go behind another window?

Could you share some screenshots of the app running? Something to help us better visualize what is happening.

[farzad]

dear Cris, well : I have one single app windows.

the first step I need to do is : to have this push button that when the user presses it, he can choose the working directory for the application.

and all the commands above , are for that push button. All I need is : independently from any next step , while the user chooses the current folder, the app window , should not go in back of other windows, which currently is does

This seems to be very similar to this request, which used uigetfile. The solution was the same. What version of MATLAB are you using? The linked post shows a different solution for releases older than r2018a.

[farzad]

I use 2017b , so I am not sure that post could help me, or not?

[Cris LaPierre]

That explains it. You need to use the second solution from that post:

"For releases prior either turn the visibility off and on again or use the attached p file (change extension from .zip to .p). The usage then would be"

uigetfile; % Could be other dialogs here
drawnow;
FocusUIFigure(app.UIFigure)

Thank you Cris, but I got an error

Undefined function 'FocusUIFigure' for input arguments of type 'matlab.ui.Figure'.

[Cris LaPierre]

FocusUIFigure is a custom function that is attached to the post I linked you to. You'll have to download it in order to use it.
