Are you sure drop-down box is not more appropriate? What sort of strings do you expect the user to input and how do you want that to correlate with the outcome?

Im trying to use it for a robot maze I want the person to put in a number that correlates to steps for the robot and when they hit the push button the robot takes that about of steps.

在 MATLAB Online 中打开

fig = uifigure;
edit = uieditfield(fig, 'numeric');
btn = uibutton(fig, 'position', [200 100 100 22]);
label = uilabel(fig, 'position', [350 100 100 22]);
btn.ButtonPushedFcn = {@button_pushed, edit, label};
function button_pushed(obj, event, edit, label)
    use_value(edit.Value, label);
end
function use_value(user_in, label)
    label.Text = string(user_in);
end
