Posix error 24

I wrote a cocoa application that periodically gets a posix error 24. I know this means my app's number of open files has exceeded kern.maxfilesperproc, however, I can't figure out when and where I'm leaving files open. This appears to be happening after accessing several hundred web pages.

Forcing ordered-out-window to adjust position

Hello, I was hoping someone could offer me some suggestions: Here is what I'm trying to do. I have a window that I create with the NSBorderlessWindowMask flag set. Since windows with this flag set don't really adopt any of the cocoa movement, sizing, or constraining behavior, I've been forced

If you can't get a direct answer to your question, could you create a subclass of NSWindow with a couple of very simple overrides: - (void) display {} - (void) displayIfNeeded {} You couldn't leave it out lest it muck with event handling, but you could order it in, position it, check its posit

I have only had the reverse problem (in some cases I need to circumvent AppKit mechanism), but have you looked at [NSWindow constrainFrameRect:frameRect toScreen:screen]: http://developer.apple.com/mac/library/documentation/cocoa/reference/ApplicationKit/Classes/NSWindow_Class/Reference/Reference

drawing into a hidden view

Hi, I have an application which swaps NSViews based on which segment of an NSSegmentedControl the user clicks on. There's one specific NSView in which I draw a graph using NSBezierPath's. This view is initialized once my application is started and always exists, it's just not always the currently

SETUP : Regular Expressions - Easy Setup for RegexKitLite

I've been using RegexKitLite for regular expressions for a little while, and the other day when I went to add it to another project, I had forgotten about the project setup. I was getting debugging errors, and finally remembered that I had to add -licucore to the other linker flags. I decided t

How did Snow Leopard kill my table view?

I wrote an application that was built on and for Mac OS X 10.5 Leopard. The main view in its main window is a stock NSTableView. I used Cocoa bindings to populate and manipulate the table view. It works fine running on Leopard, but on Snow Leopard the table view no longer enables itself when I a

This is a data table header cell of type NSPopUpButtonCell where I'm trying to draw the bottom border of the cell. The problem is that the border along the bottom of each NSPopUpButtonCell only extends across part of the cell, not the entire length of the cell. The docs say about the cellFrame "T

Framework linking errors

I'm building a Framework which internally uses OpenSSL, and exposes a sort of OpenSSL wrapper for various small purposes. However, when linking the framework, Xcode complains of missing symbols like: _ERR_error_string_n _ERR_clear_error _SSL_CTX_free _SSL_CTX_new _ERR_get_error _SSL_library_init

Re: Framework linking errors

I should mention that the obvious suggestion of "You need to link your framework against OpenSSL" is not what I'm looking for. If I link my framework statically against OpenSSL, then I force the clients of my framework to use that static version of OpenSSL, which I don't want. If I link my fram
