What is the typical information that people get from a mouse dragged

I have the following:

Thanks Eric. I have a CustomOpenGLView example that I downloaded from
the apple development site (http://developer.apple.com/samplecode/Custom_Cocoa_OpenGL/listing5.html
).
Hopefully that has what I am looking for.
Use NSOpenGLView. It's whole reason to exist is to simplify setup
and use
I think I am close but don't understand how the coordinate system of
an NSView relates to the NSWindow it resides in.
It looks like the NSView setFrame method will help but I am getting
weird results. Am I on the right track?
thanks,

Thanks Greg! Works great.
About the time I noticed your post I had ended up with this: (seems
to work)
- (void) drawRect: (NSRect) rect
{
NSWindow* main_window = [self window];
NSRect window_rect = [main_window frame];
NSLog(@"my_window_width=%f, my_window_height=%f",
window_r
he frame of the view has been
changed. I don't know of a message to track it real time.

You'll want to override the -viewWillStartLiveResize and -

Hope this helps,

Sorry, assume the @implementation/@end are there. It's not an example
meant to compile.
It sounds like what I listed can be considered synonymous with a c++
class?

I am coming from the c++ world and I feel I don't understand how
objects are scoped in obj-c.
What is the scope of m_controller (a c++ class) below? The debugger
shows m_controller as {...} with no other information. Other than that
it seems to run fine.

events are sent to the first responder and then up the responder

Awesome! Thanks Nathan. That makes a lot more sense to me.
Just set the class of the Custom View.
What do you specifically mean by 'set the class'?
