I have a GeDialog subclass that reimplements the Command method.
Whenever The command is called, I get the new parameter values.
How can i also get the previous ones ?

The reason why I need this is because I have a combo box that when switched, some buttons have to switch their images. I want to avoid switching these images if the same combo box value has been selected twice in a row.

So I want to check "If  new value is not the same as previous, switch images".

Thank you for your time.

the command message is sent after the values have been changed. So there's no built in way to get the last/old value. Instead you will have to store the old values yourself.
