There are two ways you can go about this, depending on how you see this fitting into your actual workflow.
1. create() shows a modal dialog that blocks until the user responds, and then the program can continue and the value can be checked 2. create() shows a non-modal dialog that uses callbacks (similar to what you have now), but the calling script needs to provide the callback that should be run when the value is ready. This means the calling script needs to just stop and leave the function after it shows the window, and wait to do something else by having its callback called. I will just show the easier one, doing a modal dialog. Your custom UI example looks exactly like a stock Confirm dialog, so I am going to replace it with that, because it is one of Maya's blocking UI's http://pastebin.com/BFPv9ZKX ======== class UserQueryUI(object): def __init__(self, query, affirmativeReply, negativeReply): self.name = 'userQueryUI' self.title = 'userQueryUI' self.query = query self.affirmativeReply = affirmativeReply self.negativeReply = negativeReply self.reply = None def create(self): print '--Creating userQueryUI with query', self.query yes = self.affirmativeReply no = self.negativeReply ret = cmds.confirmDialog( title = self.title, message = self.query, button = [yes, no], defaultButton = yes, cancelButton = no, dismissString = no ) print "Reply was", ret self.reply = (ret == yes) return self.reply ======== You no longer need those callbacks inside the create() method, and I would also recommend making "reply" an instance attribute instead of a class attribute. Your callbacks before were not actually setting the class attribute. They were just creating a local variable that is garbage collected. If you need it to be even more custom, you would have to use layoutDialog<http://download.autodesk.com/global/docs/maya2012/en_us/CommandsPython/layoutDialog.html> to have it show the custom UI code, but still block until it is dismissed. -- justin On Tue, Oct 30, 2012 at 1:53 PM, Chad Fox <[email protected]>wrote: > Hello > > I would like to create a ubiquitous gui class called "UserQueryUI".
