NSGraphicsContext PDF crash

I'm trying to figure out why I get a crash when drawing to a PDF CG context. From what I can tell, some resources are either corrupt or missing, but it's not easy to tell from the docs since I'm doing nothing complex and following the sample code on the apple website. All of this code lives in a

Re: NSGraphicsContext PDF crash

Are you sure this crash corresponds to your code? It looks like this is crashing when Cocoa tries to draw a window border, but the lowest-level frames are PDF-related. Are you perhaps allowing the NSGraphicsContext to outlive the CGPDFGraphicsContext it references? I wish that were the

Re: NSGraphicsContext PDF crash

NSBezierPath *p = [[NSBezierPath bezierPath] retain]; [p lineToPoint:NSMakePoint(100, 100)];  // - crashes here The 'crash' presumably is an exception stating 'no current point for operation' or words to that effect. You can't do a lineToPoint as the first op in a bezier

Re: NSGraphicsContext PDF crash

Also, the other thing that was messing things up and making it look like the problem was in window drawing is that I wasn't saving the previous NSGraphicsState before setting my PDF one to the current, so that when I call restore, things are corrupted. wes

track files even if moved

I was looking at NSFileManager and the low-level file manage docs, trying to figure out a way to track a file no matter where it gets moved on the system, even if my app is not running. For example, let's say my app references a document, but doesn't store a copy of that document. I'd like to

I've been looking around for examples on how to get tab view too look like they do on Terminal, Safari, etc. Is there any example code around? I've not found any or really any references as to how to provide a custom look to tabs. thanks, wes ___

NSPanel and mouse input / activation

Hi, I have an NSPanel window in my app that I'm putting an OpenGL context in. I want the panel to receive mouse drag events without having to first click on the panel to activate it. I've not been able to find any info on how to do this in the docs or through many google searches. Currently, if

modifier key query

Is there a way to know if a modifier key (shift, ctrl, option, cmd, etc) is pressed? Obviously, there's this: NSUInteger modifierFlags = [theEvent modifierFlags]; but what if you need to know this information independent of an NSEvent? Anyway to get it? So far I haven't seen anything

Re: modifier key query

Given that you are informed with an event each time the modifiers change, I'm not sure why you want to know this information independent of an NSEvent. Mainly because I'd like to be able to control various animating behaviors via key modifiers but if the user isn't generating new mouse or

NSTimer in main NSRunLoop v. InstallEventLoopTimer

Hi, I'm trying to figure out how I can have my app run a timer that never suspends when the user interacts with menus and the like. In Carbon, one can do: EventLoopRef mainLoop; EventLoopTimerUPP timerUPP; EventLoopTimerRef theTimer; mainLoop = GetMainEventLoop();

cmd+w and File menu

I have an application where I generate a number of the menus from scripts and runtime. Something I noticed when I replace the File menu defined in the app's MainMenu.nib is that I can no longer use cmd+w to close windows. I'm not totally sure why this is. The application loads scripts, which

NSenu and memory ownership

Hi List, I have a question regarding memory ownership and NSMenus. Let's say I have an application with a nib file containing the usual menu items like File, Edit, Window etc. If, during the execution of my app, I swap out the Window menu with another NSMenu object generated during runtime, who

Re: NSenu and memory ownership

Removing a menu with -removeItem: or -removeItemAtIndex: doesn't return anything, and in any case you didn't alloc, copy, or retain anything, so you don't have to worry about releasing anything. While this is true, I'm using - (NSMenuItem *)itemWithTitle:(NSString *)aString to get the item if

delegation strategy

Hi list, I'm trying to provide a particular windowing interface that combines NSWindow and NSPanel. For the most part I'm using a custom subclass of NSWindow that adds a decent amount of functionality. Occasionally, I want to make use of NSPanel (for the NSUtilityWindowMask style flag) and I'd
