MATLAB: Making GUI with sub-elements resizable in a quick way

guiguideresize

When developing a GUI in guide, there is a global GUIDE option that let's you make the GUI resizable in a way that all sub-elements resize proprtionately with the figure.

However, I am given a programmatically generated GUI and I would like to modify the mfile so that it is resizable in the same way. Is there a quick way to do this, i.e., by modifying a single property of the parent figure, or do I have to write a ResizeFcn callback that manually alters the size/position of the sub-elements one by one?

Add this line at the end of the code, which defines the GUI

    set( findall( fig_handle, '-property', 'Units' ), 'Units', 'Normalized' )

MATLAB: Maximize the GUI window

If your GUI was created in GUIDE(),

open your gui in guide: guide('mygui')
Select tools > GUI Options...
In the "Resize behavior" dropdown box, select 'Proportional'
Save, close
If your GUI is already opened, close it; run your GUI

If your GUI was created programmatically using UICONTROL(),

Set the units of all GUI components to 'normalized (see below)

% h is the handle to the figure hosting your gui
set(findall(h, '-property', 'Units' ), 'Units', 'Normalized' )

If your GUI was created in APP DESIGNER

open your gui in app designer: appdesigner('mygui')
From the component browser on the right, select the main figure (probably on top of the list)
In the UI Figure Properties window below, select 'Resize components when app is resized'.
Save the app; close.
If your GUI is already opened, close it; run your GUI

Now you can maximize the figure and the components should scale to the new figure size.

MATLAB: Locking All Other GUI Windows While Another is Up

To summarize my and OCDER's suggestions:

Toggle the visibility of the GUI with

handles.GUI.Visible = 'off';  % or 'on'

In the case of a malfunction when the GUI is inivisible one option is to set a try/catch as OCDER suggested in the comments above.

handles.GUI.Visible = 'off';
try
   Out = NewGUI(handles.GUI.Position, ...); %Open your new GUI 
   %Any other stuff that might trigger an error goes here....
catch E
   disp(E);
   handles.GUI.Visible = 'on'; %Restore your GUI Visibility 
end
handles.GUI.Visible = 'on'; %Restore your GUI Visibility

The second option is more reactionary and not automatic. You could write a simple function that searches for your invisible GUI and turns it back on. You could call this function from the command window or from a button in the visible GUIs whenever an error occurs. Of course you won't have the GUI handle any more so you have to search for it.

This function finds all figures, determines which ones are invisible, and turns those ones on.

function h = findMyInvisibleGUI()
% Searches for any figures that are invisible and makes them visible, 
% and returns the handles. 
allFigHandles = findall(0, 'Type', 'figure');
visibleStatus = get(allFigHandles, 'Visible'); 
isOff = strcmpi(visibleStatus, 'off'); 
h = allFigHandles(isOff); 
set(h, 'Visible', 'on')
