Hi,
I've made a funny cuartz composition with a couple of video filters,
webcam, and so on, and now i'd like to record it to a video file (like
quicktime). Question is, do i need to use OpenGL and render each frame
or whatever, or is there an easier way to accomplish this?
Thanks
Hi, I'm trying to obtain a table header that doesn't disappear when
scrolling rows. tableHeader/Footer properties support custom views that
scroll with rows and so disappear.
Please, anyone knows how to do this?
Thanks in advance

Hi folks,

I saved the project using NSArchiver with an extension say .myExtension. And

See the Runtime Configuration Guidelines:
I've already tried with a custom NSClipView, as explained here:

The output is the same, but there is also:

though, so I am switching to that instead of using
I use this code to change the fontsize:
NSFont *font1 = [NSFont fontWithName:[pop1 titleOfSelectedItem] size:[[pop2

In the second popup’s action method, you should be invoking
-[NSFontManager convertFont:toSize:] to convert the fonts to the right
size.
If you can direct the application via AppleScript to print the document to
the default printer, then you can set up a printer that prints to a PDF
file, and switch the printer programmatically. (Combination of lpadmin
defaults write commands.)

strategy might be to just go ahead and return 0 initially, and then
whenever you have successfully pulled your data from the network, do

at that time,
Yes, that's what i meant. Just to confirm.. It is safe to assume that
numberOfSectionsInTableView will be first function called ? I am thinking of
this sequence..
