Hide app icon in dock when minimized

Question

I am new at Mac OSx development.

The app that I am creating requires removing the app icon from the dock throughout the application. The app allows minimizing and closing of the app window. Relaunching or reopening of the closed or minimized app window is done by clicking the app's icon from the status bar.

I was able to set the dock icon to be disabled during app launching; however, when the app is minimized (clicking the minimize button), it captures the image of the app's current window and adds it to the dock. I don't want that to occur. The app should not add any item to the dock.

Questions:

1. Does Apple allow removal of the app's re-launcher image from the dock when minimized?
2. If Apple allows this, how can I hide or remove the app from the dock?

Any help would be a big help! Thanks!

Answer 1

You cannot disable the display of a proxy tile when your window is minimized -- that's the primary way that users will restore a minimized window. If you'd rather that the window disappear entirely when it's not being used, disable minimization (in the window's flags) and have the user close the window instead.
