Question

For my application I want to set a custom length and width for my NSWindow from within the application itself. I have everything set up (the NSTextfields) however I’m stumped with how I should do it.

Answer 1

NSRect is defined like this:

typedef struct _NSRect {
    NSPoint origin;
    NSSize size;
} NSRect;

And NSSize is defined like this:

typedef struct _NSSize {
    CGFloat width;
    CGFloat height;
} NSSize;

You need to convert your NSStrings to numbers first. You can do that like this:

CGFloat numericalValue = [stringValue doubleValue];

(I don’t actually remember if CGFloat is defined as a float or double. I’m just too lazy to look it up right now.) Note that this will cause an exception if stringValue does not represent a properly formatted number.
