Это просто, когда App1 держит дескриптор для App2.
App1:
properties (Access = private)
hApp2 % Handle to app2
end
Выполнение App2 из App1:
% Code that executes after component creation
function startupFcn(app)
app.hApp2 = App2;
end
Установка метки в App2 из App1 при нажатии кнопки:
% Button button pushed function
function ButtonButtonPushed(app)
app.hApp2.Label.Text = 'Button Pressed';
end
Полный код приложения 1 (образец):
classdef App1 < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
UIFigure matlab.ui.Figure % UI Figure
Button matlab.ui.control.Button % Button
end
properties (Access = private)
hApp2 % Handle to app2
end
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
app.hApp2 = App2;
end
% Button button pushed function
function ButtonButtonPushed(app)
app.hApp2.Label.Text = 'Button Pressed';
end
