Screens and Control flow
Please Login to Remove!
I have a question regarding control flow when pushing and popping screens off the stack.
When I push a screen onto the stack, my thread continues on to the end. What would be a good way to wait until the screen is done/popped?
For example if I have screen1 which in turn pushes screen2 am I forced to put the code for pushing screen2 into the code for screen1? Would it make more sense to control the screen pushes from the same place?
As a more real example, I have added a menu item to the Compose email page in the Mail application. When the user invokes it, I send the email and then my own screen is pushed onto the stack. When done, the screen pops itself, but then I am back on the compose page. I know how to pop the current screen, the question is "from where"?
Thanks
John
