Mantaining legacy APIs in a framework

Hi all, a fairly general question. Suppose I have a framework class - e.g. GCBase - that has a public method -foo: Application code that links to the framework can freely subclass GCBase and commonly overrides -foo: Later, I decide that the method would be much better in a different form, let’

How to terminate an NSTask whenever my app terminates?

(I know this has come up here before, but I can’t get the right combination of search terms to find an answer…) I’m writing a little GUI wrapper app around a command-line-based server. It uses NSTask to launch the server. I want to ensure that when the app exits, the server process exits too. I

NSTableView: Rows from bottom up

Normally when one adds the first row to a NSTableView, it will appear at the top of the view and additional rows will appear below it. Is it possible to have the first row appear at the bottom of the NSTableView and for new rows to appear above it? No doubt this would require some extensive cus

Re: How to terminate an NSTask whenever my app terminates?

Normally, when a parent exits, all child processes are killed. This is not specific to terminal/tty sessions. However, a process can be detached from its parent so that it will survive the parent's exit. I doubt that NSTask does this, but you should verify. Create a dummy helper: int main() {wh

Re: How to terminate an NSTask whenever my app terminates?

On the UNIX command line "nohup" prevents children from being killed when the parent exits. If you want to manually start a daemon: $ nohup mydaemon & Then you can log out and it keeps running. -- Michael David Crawford P.E., Consulting Process Architect mdcrawf...@gmail.com http://mike.so
