GUI FAULT INDICATOR (GREEN, RED)

HI, i want a FAULT indicator in my GUI. lets say A red circle, or a green circle. is there something simple, built in the GUI that i can use? i dont really want to draw a circle from scratch every place i want an indicator

Using rectangle makes it trivial to define a circle (yes it is the correct function).

Define your own class, and then instantiate an instance for wherever you need it. Or define a simple function to call to define the circle, and then set its patch color when you need to.

If you are using R2016a and the App Designer you can use

doc uilamp

to do this I would think. I haven't used the App Designer or its components yet myself though so I don't know what the limitations are on GUIs created that way are.

For dead-simple notification, just fill the BackgroundColor of your favorie ui object.

Try this as a template:

function toggleTest
% Make fig
figure('Visible','off',...
    'OuterPosition', [0 40 400 400],...
    'MenuBar', 'none',...
    'ToolBar', 'none');
hFig = gcf;

% A simple pushbutton
uicontrol(hFig,'Style','pushbutton',...
    'Units', 'norm',...
    'Position',[0.2 0.6 0.6 0.25],...
    'String','TOGGLE',...
    'Callback',@toggleColor);

% STATUS INDICATOR --------------------------
uipanel(gcf,'units','norm',...
    'Position',[0.2 0.2 0.6 0.25],...
    'BackgroundColor','g',...
    'tag', 'PANEL_TOGGLE')
% --------------------------------------------

% Save toggle state
data.TOGGLE_STATE = true;

% Pass Handles
data.Handles = guihandles(hFig);

% Save & Launch
guidata(hFig,data);
movegui(hFig,'center')
hFig.Visible = 'on';
end

function toggleColor(hObj,~)
h = guidata(hObj);

switch h.TOGGLE_STATE
    case true
        h.Handles.PANEL_TOGGLE.BackgroundColor = 'r';
    case false
        h.Handles.PANEL_TOGGLE.BackgroundColor = 'g';
end

h.TOGGLE_STATE = ~h.TOGGLE_STATE

guidata(hObj,h);
end
