Hello
How do i can use an if statement to know if a push button is pushed?
Example:
function button1pushed(app,event)
if button2pushed==1 (error here: To many output arguments)
errordlg('You can't push the 2 buttons','Error');
end
else
do something
end

请先登录，再回答此问题。

A push button cannot "stay pushed", as soon as you click it the callback is called and then the state is reset. If what you mean is the State Button, then you can get it's value as:
if app.button2pushed.Value ==1
However, to make exclusive choices the best option is actually to use a Radio Button Group or Toggle Button Group (some documentation is here).
