For example the following code snippet makes the insertion point change (it
moves to the next line) (whereas the code never uses the insertion point) :
- (void)textStorageWillProcessEditing:(NSNotification *)aNotification
{
NSTextStorage *storage=[aNotification object];
if ([storage editedMask] & NSTextStorageEditedCharacters)
{
NSRange range=[[storage string] lineRangeForRange:[storage
editedRange]];
NSDictionary *attrs=[NSDictionary
dictionaryWithObjectsAndKeys:[NSColor
textColor],NSForegroundColorAttributeName,nil];
[storage setAttributes:attrs range:range];
}
}
Is there an obvious bug here ?
All I want to do is to reset the paragraph's color (here it is dumb, but in
fact it's an extract - which is bugging too - from some syntax-colorization
code).
Thanks in advance (and sorry if my question is stupid),
