I have an NSTextField with an associated NSNumberFormatter which I am
using to format the values shown to a specific number of decimal
places. I have a second NSTextField which I am using to display and
edit the number of decimal places that I want shown and I have used
the controlTextDidEndEditing delegate method to detect a change. Upon
a change I am using the setMinimumFractionDigits and
setMaximumFractionDigits methods of the NSNumberFormatter to change
the number of decimal places to be shown but I am having trouble
getting the NSTextField to refresh without giving the control the focus.
If I change the value of the field then the value is displayed
correctly:
float temp;
temp = [netAmountField floatValue];
temp++;
[netAmountField setIntValue:(int)temp];
If I don't actually change the value then the NSTextField is not
refreshed:
[netAmountField setFloatValue:[netAmountField floatValue]];
I'm fairly sure that this is simply due to the NSTextField being
clever enough to realise that the value has not changed and therefore
it doesn't re-display the value and trigger the new format and I am
equally sure that I'm missing a simple way to achieve the refresh but
after an hour of messing around I though I'd ask wiser folk.
Many thanks.
Simon
