Guillaume Borios fixed bug #508
When unicode translation is ON, pressing the escape key raise an NSBeep()
because the NSTextView interprets the key as a special command (in that case
impossible to interpret)... The NSTextView instance should replaced by
something subclassed so that doCommandBySelector: does nothing.
Example code :
@interface SDLTranslatorResponder : NSTextView
{
}
- (void) doCommandBySelector:(SEL)myselector;
@end
@implementation SDLTranslatorResponder
- (void) doCommandBySelector:(SEL) myselector {}
@end

Each table is an array of 256 Uint16 values, representing a mapping between the input and output for that channel\&. The input is the index into the array, and the output is the 16-bit gamma value at that index, scaled to the output color precision\&. You may pass NULL to any of the channels to leave them unchanged\&. .PP This function adjusts the gamma based on lookup tables, you can also have the gamma calculated based on a "gamma function" parameter with \fISDL_SetGamma\fR\&. .PP Not all display hardware is able to change gamma\&. .SH "RETURN VALUE" .PP Returns -1 on error (or if gamma adjustment is not supported)\&. .SH "SEE ALSO" .PP \fISDL_SetGamma\fR \fISDL_GetGammaRamp\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:01
