How to change automatically generated uibutton properties in another function?

The following code is run at startup that generated buttons based on a number of unique files in a folder. The callbackfcn is another function, where the user would choose one of these buttons. At that point, i'd like to highlight the chosen button, which is easy, but i would also like to grey out, or delete the other buttons. The qquestion is how to I access the other buttons that were generated?! I can get to the button that was clicked easily, just not the other ones.

            %
            % make buttons
            numButtons = max(size(app.orientationUnique));
            for b = 1:numButtons
                posidx = b*(30+app.TheHuntGUI.Position(1));
                app.orientationButtons = uibutton(app.TheHuntGUI, 'push');
                app.orientationButtons.FontName = 'Arial';
                app.orientationButtons.FontSize = 18;
                app.orientationButtons.FontWeight = 'bold';
                app.orientationButtons.Position = [posidx 500 120 40];
                app.orientationButtons.Text = app.orientationUnique{b};
                app.orientationButtons.Tag = app.orientationUnique{b};
                app.orientationButtons.ButtonPushedFcn  = createCallbackFcn(app, @orientationButtonPushed, true);
            end

Resolved.

numButtons = max(size(app.orientationUnique));
for b = 1:numButtons
    posidx = b*(30+app.TheHuntGUI.Position(1));
    app.orientationButtons(b) = uibutton(app.TheHuntGUI, 'push');
    set(app.orientationButtons(b),'FontName','Arial');
    set(app.orientationButtons(b),'FontSize',18);
    set(app.orientationButtons(b),'FontWeight','bold');
    set(app.orientationButtons(b),'Position',[posidx 500 120 40]);
    set(app.orientationButtons(b),'Text', app.orientationUnique{b});
    set(app.orientationButtons(b),'Tag',app.orientationUnique{b});
    set(app.orientationButtons(b),'ButtonPushedFcn',createCallbackFcn(app, @orientationButtonPushed, true));
end

You can store all your buttons as an array in the app property orientationButtons.

function create_buttons(app)
% % make buttons 
numButtons = max(size(app.orientationUnique)); 
for b = 1:numButtons 
    posidx = b*(30+app.TheHuntGUI.Position(1)); 
    app.orientationButtons(b) = uibutton(app.TheHuntGUI, 'push'); 
    app.orientationButtons(b).FontName = 'Arial'; 
    app.orientationButtons(b).FontSize = 18; 
    app.orientationButtons(b).FontWeight = 'bold'; 
    app.orientationButtons(b).Position = [posidx 500 120 40]; 
    app.orientationButtons(b).Text = app.orientationUnique{b}; 
    app.orientationButtons(b).Tag = app.orientationUnique{b}; 
    app.orientationButtons(b).ButtonPushedFcn = createCallbackFcn(app, @orientationButtonPushed, true); 
end
end

function orientationButtonPushed(app,event)
btnclicked = event.Source;
allotherbtns = app.orientationButtons(~ismember(app.orientationButtons,btnclicked));
end

Also I suggest you use uigridlayout as the parent for your buttons. This will automatically adjust the sizes of the button based on the available space instead of manually setting the positions in code.

Hey, thanks for your response. I had tried indexing, but kept running into the error where dot indexing is not supported for the variable. I can create the button with dot indexing, but the error pops up at the like where I try to change the appearance (font).

[Mohammad Sami]

How did you access the fontname property. You need to but the index before the .FontName.

app.orientationButtons(b).FontName = 'Arial';

resolved. cant get your solution to work, but the uigridlayout is a good idea. thank you.
