So, this is what a formatter method that successfully works for floating point
looks like in this case:
control = [[NSTextField alloc]
initWithFrame:NSMakeRect(0, kVOffset + totalHeight - 3, kDefaultWidth, 19)];
[[control cell] setWraps:NO];
[[control cell] setScrollable:YES];
[[control cell] setFont:[NSFont
systemFontOfSize:[NSFont smallSystemFontSize]]];
formatter = [NSNumberFormatter new];
[formatter
setFormatterBehavior:NSNumberFormatterBehavior10_4];
[formatter setMinimumFractionDigits:0];
[formatter setMaximumFractionDigits:20];
[formatter
setNumberStyle:kCFNumberFormatterDecimalStyle];
[formatter setMinimum:minNumber];
[formatter setMaximum:maxNumber];
[[control cell] setFormatter:formatter];
[formatter release];
[[control cell] setSendsActionOnEndEditing:YES];
Where maximum fraction digits helps control... the maximum fraction digits
obviously :-) (In some cases QC truncates this in weird lengths for the
purpose of display, so this was a little interesting find). What's crucial is
setting the formatter behavior and decimal style.
BTW, I noticed that the version of the QCTV project that's on the ADC seems to
be older than the one that was in the 10.5 Developer Examples folder. The one
at the ADC seems to be from the WWDC from back then.
