Hello,
Sorry for a pretty long mail but my (still) desperate attempts
deserve some explanation (-:.
I'm in need of WebKit therefore I have to use Cocoa. Not that I did
not like Cocoa (it's truly amazing!!), but I have to use C/C++ for a
plug-in I'm programming and have to do that in CodeWarrior to match
the structure of STL.
The problem I have is that I need to create NSWindow and embed
WebView into it. I created a Cocoa bundle project in Xcode and put a
simple code that creates a window first:
void* WVB_CreateWindow(const Rect *iRect)
{
NSWindow* progress = [[[NSWindow alloc]
initWithContentRect:NSMakeRect(iRect->left,iRect->top,iRect->right-iRect->left,iRect->bottom-iRect->top)
styleMask:NSBorderlessWindowMask backing:NSBackingStoreRetained
defer:NO] autorelease];
[progress setHasShadow:NO];
[progress setOpaque:YES];
[progress makeKeyAndOrderFront:nil];
return progress;
}
and use Carbon code to load that bundle, find WVB_CreateWindow's
function pointer and execute it. The problem is however that the
application plug-in runs in is a Carbon app and therefore no
NSApplication object exists and AppKit is not initialized. The
program ends with:
*** Uncaught exception: <NSInternalInconsistencyException> Error
(1002) creating CGSWindow
If the same code gets executed from a -(void)awakeFromNib method from
a testing cocoa app that calls NSApplicationMain, everything works
normal.
I'd like to get advised on how to:
a) have Cocoa/AppKit initialized (I assume I cannot call
NSApplicationMain(argc,argv) to not let underlying app go mad )
I don't know what AppKit does in its initialization but this seems that
it estabilishes a connection with WindowServer and creates a raw window
with CoreGraphics Services API. That would explain why the buffering
method is required with initWithContentRect method.
b) make this work
c) make this work better (-:
Thanks,
Tomas
