nsDialogs doesn't appear to have a built in handler so the best thing I can think of is to set a variable to 1 before ::Show and to 0 in the custom page's leave callback function (and in the previous page's pre callback function if there is a previous page). Then check the variable value in your abort callback function (set using MUI_CUSTOMFUNCTION_ABORT) to determine whether or not the user cancelled while on your custom page. Your other option is to write a plug-in which grabs the value of extra_parameters->abort (set to 1 after Cancel has been pressed).
