I am writing a custom dialog using the custom dialog builder to handle complex contrasts within ANOVA.
What I can't figure out is how to create a number control that will allow you to have multiple numbers in it. For example: -0.5 0 0 1 -.05
What I'd like to do is have a number control where you put one number in and then press a next button where it moves that number to a multiple number control, and then allows for another number to be entered. It would be like the contrast field in the one-way anova contrast options. I have added a picture of the one from ANOVA here.
Any ideas on how to do the part in the red box in the picture?
