How to hide or disable a button?

[Outy]

Hello,

I have to hide or disable(make grey)certain buttons when another one is pushed.
How can I do this?
Is it also possible to display a simple messagebox with information and an ok or cancel button when a button is pushed?


Thx
Outliner

hello
you can disable button as
but1.setEnable(false);
and remove the visiblity is
but1.setVisible(false);

these part of code should be in the other button actionlistenre when on its click we have to disable or remove the button.
