To start of: I've have no cocoa or objective-c programming experience. I don't plan on learning either one (or at least learn it GOOD). So I'd like someone to help me with a little problem to help me on my way.

So, what I basicly want to use c++ in my entire game-engine and only use objective-c when encapsulating an openGL view (which I want to create dynamicly). This because I need to (i guess..) create one from my main loop and from what I've gathered about cocoa is that you pre-define a view in the .nib file in Xcode. I'll give my main loop as an example of what I want to achieve (this works in window or linux (with x11 which I do not want to use either because I don't know it^.^)):

EXAMPLE:
Code:
#include "glwindow.h"
#include "applicationEntrypoint.h"

// Some main function...
int main(int argc, char** argv)
{
    //example window settings
    const int windowWidth = 1024;
    const int windowHeight = 768;
    const int windowBPP = 16;
    const int windowFullscreen = false;

    GLWindow programWindow;

    //Add application to the window (app calls openGL stuff within)
    applicationEntrypoint app;
    programWindow.attachApplication(&app);

    //Attempt to create the window
    if (!programWindow.create(windowWidth, windowHeight, windowBPP, windowFullscreen))
    {
        //If it fails
      // Do some notification
      programWindow.destroy(); //Reset the display and exit
        return 1;
    }

    if (!app.init())
    {
        ///do some stuff..
        programWindow.destroy(); //Reset the display and exit
        return 1;
    }

    //This is the mainloop, we render frames until isRunning returns false
    while(programWindow.isRunning())
    {
        programWindow.processEvents(); //Process any window events

        //We get the time that passed since the last frame
        float elapsedTime = programWindow.getElapsedSeconds();

        app.prepare(elapsedTime); //Do any pre-rendering logic
        app.render(); //Render the scene

        programWindow.swapBuffers(); // probably different in macos?
    }

    app.shutdown(); //Free any resources
    programWindow.destroy(); //Destroy the program window

    return 0;
}

I understand the concepts but I can't get RaiseMan even started - i.e. no GUI window shows up even though the console logs normally.

I will try starting from the beginning, presumably I have confused something along the way.

My particular problem though is that none of the files match the filenames in the book, presumably because of OSX and XCode changes since publishing.
The book states: "Note that the class MyDocument has already been created for you. MyDocument is a subclass of NSDocument."
But I only have RaiseManDocument.h, RaiseManDocument.m, RaiseManDocument.xib and MainMenu.xib...and main.m in supporting files.
I think I need to sort this out before I go any further?
Any comments would be appreciated.

}

When I compile, I don't get some error but several warnings like :

When the user click the customer button the customer window (Customers.xib) should be loaded) from MainMenu.xib I get this error message :

I have tryed this in mainMenuController.m

but I get a warning like this ""CustomerWindowController could not respond to initWithNibName message "

What can I do to resolve this issue ?

- I need a to keep a list of all the students (current and old students) and each student can be in more than one year (i.e. they can take the course in several years if they fail).

- For the current curse (for ex. 2011) I want to keep track of 1) the attendance to classes.

I have made one entity named Students, with a relationship to another entity Course (many to one) (See the attached graph). So no problem yet. Then I have created another entity named Classes which stores info about each class of the course and have a many to one relationship to Course. The problem arises here, because then I want to keep track of the attendance of each "Student" belonging to the "Course" for each "Class", and I cannot figure out how to do that. I have created one entity named AssistanceToClass, with a relationship to Class (many to one) which was meant to store the assistance for each Student to the corresponding class, so I need to have one managed object "AssistanceToClass" for each Class, for each Student in the Course corresponding to the Class, but that is not possible, I think.

Is my graph correct or should I reorder the entities to something more convenient? Or just trash this graph and start over with a new approach? All this, keeping in mind that then I need to make a table of assistance, with one column for each class, and one row for each student.

Thanks in advance,

Roger
