Wait until object is rendered in App Designer

Hello together,

I'm using the loading screen as desribed here, while my data is loaded.

The loading screen is closed, when the last function has finished. But no objects are rendered at this moment.

I'm creating a lot of buttons and edit fields programatically. But they are rendered very late, after the functions are already finished.

How to wait with closing the loading screen, until everything is rendered (or nearly at least)?

Thanks in advance!

More info would be helpful about interactions of these functions and UI components. I don't think that there is some reliable way to wait for the components to show up on the screen. After creating the last component, I would suggest to use pause and drawnow.

Perfect Mario! It worked with drawnow at the end of the loop for creating buttons.

Thank you very much:)

Here's a snippet.

%...Loop for creatng ~250 buttons...

% Default buttons into MU analog tab - no signal. Date, Time, Time [s], Event

else

app.Logs(app.Log).Variables{2, i} = uibutton(app.MUTab, 'state'); %Creating a Default Button in MU Analog TAB

app.Logs(app.Log).Variables(3, i) = num2cell(2);

app.Logs(app.Log).Variables(4, i) = {'MUTab'};

app.Logs(app.Log).Variables{2, i}.Tag = 'noPlot';

end

app.Logs(app.Log).Variables{2, i}.Position = A; %Giving the Button a position

app.Logs(app.Log).Variables{2, i}.Text = app.Logs(app.Log).Variables(1, i); %Giving the Button it's Text

if i == 2 || i == 3 || i == 4 % Show buttons pushed for the first x columns

app.Logs(app.Log).Variables{2, i}.Value = 1; % Button activated

app.Logs(app.Log).Variables{2, i}.BackgroundColor = [0.75 0.97 0.75]; % Light green for activated state

end

% Random colors per variable for plot

RandomColor = rand(1, 3);

if ((RandomColor(1) > 0.9) && (RandomColor(2)) > 0.9 && (RandomColor(3) > 0.9))

RandomColor = RandomColor - [0.1 0.1 0.1]; % Shift darker if too bright

elseif ((RandomColor(1) < 0.1) && (RandomColor(2) < 0.1) && (RandomColor(3) < 0.1))

RandomColor = RandomColor + [0.1 0.1 0.1]; % Shift lighter if too dark

end % Put random color into button user data

app.Logs(app.Log).Variables{2, i}.UserData(1,2:4) = RandomColor(1:3);

app.Logs(app.Log).Variables{2, i}.ValueChangedFcn = @app.DataButtonPress; %Callback function for variable buttons

app.Logs(app.Log).Variables{2, i}.UserData(1,1) = i; % Put Nr of Variable in Userdata of button

posEdit = A;

posEdit(3) = 24; % Position for Editfield for this button/variable

posEdit(1) = A(3) - A(1) +1 ;

app.Logs(app.Log).Variables{5, i}.Position = posEdit;

app.Logs(app.Log).Variables{5, i}.Value = 0;

A(2) = A(2) -21; %Position change for the next Button

end

% forces rendering before going on(?)

drawnow
