Hi Frederik,
Have you tried wiring your window to an IBOutlet of your Controller
and displaying it with [window makeKeyAndOrderFront:nil]; ?
This works for me anyway.
HTH,
Florian.

Hi all,
I'm trying to make a Photoshop plugin with a Cocoa user interface,
but I'm running into a persistent problem: after closing the plugin
window, Photoshop crashes 90% of the time with the following call
stack:
#0 0xa04590d8 in _XHNDL_trapback_instruction
#1 0xbf800fac in ??
#2 0x917ea9a2 in __CFRunLoopDoObservers
#3 0x917ebcfc in CFRunLoopRunSpecific
#4 0x917eccd8 in CFRunLoopRunInMode
#5 0x969f42c0 in RunCurrentEventLoopInMode
#6 0x96aa7904 in GetNextEventMatchingMask
#7 0x96aa7766 in WNEInternal
#8 0x96aa76c5 in WaitNextEvent
I've tried every suggestion I could find. The main plugin is a
Carbon bundle that locates the Cocoa bundle that actually contains
the core plugin as suggested here:
http://furbo.org/2008/07/08/plug-ins-the-cocoa-way/
The Cocoa bundle exports a plugin entry point as a C function. The
Carbon bundle calls this from its own entry point using
CFBundleCreate / CFBundleGetFunctionPointerForName, but it never
releases the Cocoa bundle since apparently Cocoa bundles should not
be unloaded. The whole idea behind this, as far as I can see, is
that Photoshop unloads the Carbon bundle, but does not unload the
core Cocoa bundle.
Next, the Cocoa bundle calls NSApplicationLoad, displays an empty
window using [NSApp runModalForWindow], then closes the window and
returns. At this point, I get the aforementioned crash.
What am I doing wrong? Any pointers would be highly appreciated --
I've been staring at this for about three days now...
Best regards,
Frederik Slijkerman
