Mixing Qt and platform-dependent development

[Peppy]

Hello guys, I wonder how can develop with Qt and Objective-C in QtCreator? I'd like to use the full "power" of the platform...

Hi,

Just have a look at the qtmacextras code/examples to see how to mix both

Hope it helps

Okay, is there any way I can configure QtCreator to work with Objective-C code?
Somehow my syntax-highlighter of Objective-C code seems to be broken. (http://goo.gl/oybesZ )

[SGaist]

Nothing to configure, in your pro file just add the objective-c/c++ source files to OBJECTIVE_SOURCES rather than SOURCES

[Peppy]

Yes, but QtCreator somehow does not handle those files (syntax highlighting is somehow broken).

[SGaist]

Which version of Qt Creator are you using ?

[Peppy]

Well 3.1.2 now. I am not sure how should correct syntax highlight look like.

[SGaist]

Did you download the syntax highlight definition file for Objective-C/C++ ?

[Peppy]

Yes I did, but it doesn't work correctly.

Well, I have figured out how to compile Objective-C/C++ code within QtCreator but I am not able to somehow connect C++ and Objective-C code. I'm getting weird errors like:

@.../System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:422: error: unknown type name 'NSString'; did you mean 'QString'?
FOUNDATION_EXPORT void NSLog(NSString *format, ...) NS_FORMAT_FUNCTION(1,2);
@

I'm really not sure how to bind these two guys together.

[SGaist]

Can you show your code ?

[Peppy]

Well, okay:
I have in MainWindow.cpp something like this:

@
#include "NativeWindowExtensions.h"

struct NativeWindowExtensions;
class MainWindow : public QMainWindow {
NativeWindowExtensions * native;
};
@

NativeWindowExtensions.h contains C++ struct which stores Objective-C object (NSWindow):

@
#import <Cocoa/Cocoa.h>

//objective-C code

// c++ code
@

which doesn't work.

[SGaist]

It would help to have the content of NativeWindowExtensions.h
