Thanks! (on both counts, although the extra retain was a last ditch,
"just in case I'm not retaining it" check. honest ;) )

I'd like to be able to create and display an NSTextField
programatically (rather than linking to a pre-made one from IB). I've
had a go at making one appear in the drawRect of the view I want it to
appear in by doing...
tempTextField = [[[NSTextField alloc]
initWithFrame:tr] retain];
[tempTextField setEditable:YES];
[tempTextField setSelectable:YES];
[tempTextField setStringValue:[tempObject
objectName]];
[tempTextField setBackgroundColor:[NSColor
whiteColor]];
[tempTextField setDrawsBackground:YES];
[tempTextField setBordered:YES];
[tempTextField setNeedsDisplay:YES];
but nothing displays. kind of indicating I'm doing something wrong.
I haven't been able to find any examples where someone's
programatically creating a text field. They all seem to use the
Interface Builder route. Does anyone know if it's possible and if so,
Of course it's possible (i.e. there's nothing magic about IB; anything
it can do, you can do in code).
what am I doing wrong ?
You're not adding the textfield to any view or window. In order for a
view to be displayed, it must be in the view hierarchy of a visible
window. For example, if you have a pointer to the window in which you
want the text field to reside, you can do this:
[[myWindow contentView] addSubview: tempTextField];
(Also, BTW, you're retaining that text field too many times. When you
create it via -alloc, it is already implicitly retained once, and you
are retaining it a second time)
