Hello,
I'm trying to write a very simple oscilloscope in Cocoa as a shell
tool that continuously reads samples via standard input and draws
them as a waveform in a window. I do _not_ want a menu bar (i.e. an
application), just one window that disappears when the parent shell
tool receives the interrupt signal.
- How can I create a window without creating a full fledge
application (i.e. without creating an instance of NSApplication)?
- What is the difference between a Cocoa Shell Tool and a Cocoa
Application? Can a Cocoa Shell Tool draw GUI objects, or is it
restricted to text in the shell?
- How can I read standard input? With the NSFileHandle class? I see
fileHandleWithStandardInput is a class method there, but not an
instance method...
- How can I draw an oscilloscope type "animation"? With the drawRect
method of my own class that inherits from NSView? Or is there a more
appropriate method?
I'd appreciate any pointers in the right direction.
Chris
Another way to do this would be to write the entire app in either C or
Objective C (without any Cocoa frameworks) and use OpenGL to handle
the graphics.
