I'm develop an application with an NSTableView and a NSTextField these
will be synchronized, that is, when the user click in the NSTableView
the value of one of its cells will be the value of the NSTextValue.
I implement the tableViewSelectionIsChanging to capture the selection

sorry if this sounds like a stupid question, but i need to know how
to use NSTable,
Are there any tutorials/source code showing how to implement an
NSTable.

Most of my database development was done during my "day job" where I
worked on a PC and used MS's Enterprise Manager. Now that I'm doing
more of this work elsewhere, I'm doing so on my platform of choice
which is the Mac.

I am coding for windows and am trying to establish a gworld to render into,
so that I can later grab the movies pixels for other purposes. No matter
that I try I get a -157 (invalid pixel depth) error. The example can hardly
be simpler than what I have here, so I hope someone can ...

I seem to remember being impressed with the ProjectBuilder's ability to
find the latest Java documentation on Sun's web site.  Maybe it was the
first XCode.  In any case, I haven't used XCode for a while, and after
the Feb 6 RefLib update, the Java documentation lookup no longer ...

I have a program that gets in an uninterruptible wait for
hours and days. I'm using sockets and kqueue. I have never
had problems with sockets before, but kqueue used to crash
the kernel. Does anyone know if kqueue still borks the machine?

hello to everyone!
These days I am trying to create a plug-in for an Image Processing-
Design software running on a Mac. I have been already using a small
document management software which is originally coded (by me) in C++

I have a 10x10 grid of NSColorWells ( the user can choose colors for a
3D visualization based on permutations of 10 parameters).
It would be useful if my app could initially read the values from the
nib. I don't want to have to create 100 IB Outlets, so I thought about

Is there a simple way of doing this? Cocoa does not seem to provide a
method for doing this, at least nothing within either class seems to fit
the fit the bill. It looks like I'll have to write my own parser, is
that the case?

I have a rather large XCode project that seems to have some internal
errors, when I open it and use it I get a stream of dialog boxes
saying:
--------------------

Does anyone know why the NSColorWell stops automatically responding to
mouse clicks when you choose to have it without a border. Space is
tight; I have a grid of them and could do with the extra pixels.
Also, why is there no option to have a matrix of them in IB? Option-

Is there a way to get the duration from an NSSound?

I've subclassed NSTableColumn and overridden the dataCellForRow:
method so that I can add an NSPopupButtonCell to my NSOutlineView.
My PopupButtonCell appears, but the problem is that when I select a
different item in the popup, it immediately returns to first item that

By implementing setDoubleAction: I can trap double-clicks in a table,
but how can I tell what row number was doubleclicked?
Sorry, probably easy but I just can't seem to find out.
Many thanks.

When I try to set the text in one of my NSTextFields, below, I get the
error:
[stringDisplayField    setStringValue: @"Hello"];
*** -[NSTextView setStringValue:]: selector not recognized [self =
