Re: allKeys and allValues

Hi Dave, Thanks. Your solution seems to be fine NSArray * allKeys = [dictionary allKeys]; NSArray * allValues = [dictionary objectsForKeys:allKeys notFoundMarker:[NSNull null]]; I also took a better look at the iTunes Music Library.xml dictionary, and there is a fine trick. The Tracks dictionary

Confused about floats

I've got two float values (x and y) that I'm using to change the coordinates of a drawing action that is being looped through. I can add a value to x and it draws the next image along, but I want to test the value of x and if it is out of bounds I want to reset it to zero and increase y, so

FSCatalogSearch miss file

Hello folks, I'm using FSCatalogSearch to find files on HFS+ formatted RAID and found that I don't have one file in the search results. There is nothing different on the file (permissions, special characters etc). Does anybody have an idea what could be wrong? Corrupted index? Thanks Robert __

Partially opaque window with opaque views

Is there a way to have a window with a 50% opaque background, but several odd-shaped views that are 100% opaque? The dock does this but seems be one window per icon. Can I do it all as one window? My NSWindow subclass looks like: [self setOpaque:NO]; [self setHasShadow: YES]; [self setLevel:NSFlo

NSOutlineView multi cell type binding query

Re: Partially opaque window with opaque views

Yes, but you should leave the window's alpha at 1.0. Off top of my head, it goes something like this: Create a subclass of NSView and set that class as the class for the contentView of the window (in IB) Change that class's drawRect to : - (void)drawRect:(NSRect)rect { // Clear the drawin

Checking for nil-return

Hi, I'm cleaning up my code and I'm wondering about constructs like the next one: [NSNumber numberWithUnsignedChar:i] The documentation does not say it can return nil on failure, but does that mean it simply will never fail? What if there is no memory left? Kind regards, Remco Poelstra

RE: Confused about floats

Also if x is a float, make sure you use the proper type cast, or values, ie ( x = x + 120.00) or (x = y + (double)z , where x and y are double and z is an int). Remember int, float, double, are C types, and typecasting rules should be in effect. > From: gwes...@mac.com > Date: Tue, 5 Oct

Re: Confused about floats

Both C and Objective-C support implicit casting for the primitive types. float f = 100.0f; f += 100; will give the expected result, because the compiler will see (float) + (int) and cast the int to a float automatically. The conversion rules are part of the ANSI C standard and apply in Objectiv

RE: Confused about floats

:*S Yes... I see the point. Correct. For a constant value this is true, in the instance of x = x + 1 (which I see where the error was), where x is a float this makes no difference. However, for clarity of the OP, x = x + y where y is an int, should be typecast correctly as x = x + (float)y

Re: Confused about floats

You can, but again this is just being explicit - the compiler bases promotion decisions on type alone, not whether or not an expression is a constant or a variable. The one important thing to remember is that promotion of assignment is applied *after* the RHS is evaluated, i.e. float f = 1 /
